53-531: Common types of standers include: sit to stand, prone, supine , upright, multi-positioning standers, and standing wheelchairs . Long leg braces are also a standing device but not used often today. Standers are used by people with mild to severe disabilities such as spinal cord injury , traumatic brain injury , cerebral palsy , spina bifida , muscular dystrophy , multiple sclerosis , stroke , Rett syndrome , and post-polio syndrome . Standers are used by people with both paraplegia and quadriplegia since

106-425: A blood pressure, it is not recommended to remove the collar without adequate personnel to manually hold the head in place. In contrast to basic airway management maneuvers such as head-tilt or jaw-thrust, advanced airway management relies on the use of medical equipment. Advanced airway management can be performed "blindly" or with visualization of the glottis by using a laryngoscope . Advanced airway management

159-454: A conduit through which to administer certain drugs. The most widely used route is orotracheal, in which an endotracheal tube is passed through the mouth and vocal apparatus into the trachea. In a nasotracheal procedure, an endotracheal tube is passed through the nose and vocal apparatus into the trachea. Alternatives to standard endotracheal tubes include laryngeal tube and combitube . Surgical methods for airway management rely on making

212-406: A cuff, and anatomic location of the device's distal end. The most commonly used devices are laryngeal masks and supraglottic tubes, such as oropharyngeal (OPA) and nasopharyngeal airways (NPA). In general, features of an ideal supraglottic airway include the ability to bypass the upper airway, produce low airway resistance, allow both positive pressure as well as spontaneous ventilation, protect

265-443: A standing frame, has traditionally been incorporated into rehabilitation programs for those with chronic spinal cord injury in order to prevent osteoporosis. A systematic review of the literature conducted by Biering-Sorenson et al. (2009) shows that therapeutic standing in the chronic phase of injury, defined as one year after injury, has no effect on maintaining bone density . Results on the effectiveness of therapeutic standing during

318-520: A supraglottic airway can be utilized to aid in oxygenation and maintenance of a patent airway. An oropharyngeal airway is acceptable, however nasopharyngeal airways should be avoided in trauma, particularly if a basilar skull fracture is suspected. Endotracheal intubation carries with it many risks, particularly when paralytics are used, as maintenance of the airway becomes a challenge if intubation fails. It should therefore be attempted by experienced personnel, only when less invasive methods fail or when it

371-519: A surgical incision below the glottis in order to achieve direct access to the lower respiratory tract , bypassing the upper respiratory tract . Surgical airway management is often performed as a last resort in cases where orotracheal and nasotracheal intubation are impossible or contraindicated . Surgical airway management is also used when a person will need a mechanical ventilator for a longer period. Surgical methods for airway management include cricothyrotomy and tracheostomy . A cricothyrotomy

424-419: A variety of support options are available to accommodate for mild to severe disabilities. Doug Betters and Mike Utley are both former NFL football players who are quadriplegics due to spinal cord injury. They both stand using active standers. Bone mineral loss and osteoporosis are common consequences after spinal cord injury . Therapeutic standing, a weight-bearing intervention that can be applied using

477-442: Is non-invasive , quick, and relatively simple to perform. The simplest way to determine if the airway is obstructed is by assessing whether the patient is able to speak. Basic airway management can be divided into treatment and prevention of an obstruction in the airway. Treatment includes different maneuvers that aim to remove the foreign body that is obstructing the airway. This type of obstruction most often occurs when someone

530-461: Is a primary consideration in the fields of cardiopulmonary resuscitation , anaesthesia , emergency medicine , intensive care medicine , neonatology , and first aid . The "A" in the ABC treatment mnemonic is for airway. Basic airway management involves maneuvers that do not require specialized medical equipment (in contrast to advanced airway management). It is mainly used in first aid since it

583-561: Is a surgical procedure in which a surgeon makes incision in the neck and a breathing tube is inserted directly into the trachea. A common reason for performing a tracheotomy includes requiring to be put on a mechanical ventilator for a longer period. The advantages of a tracheotomy include less risk of infection and damage to the trachea during the immediate post-surgical period. Although rare, some long term complications of tracheotomies include tracheal stenosis and tracheoinnominate fistulas. The optimal method of airway management during CPR

636-465: Is achievable in most developed countries, but usually requires medical justification and a letter of medical necessity (a detailed medical prescription ) written by a physical therapist or medical professional. Supine position The supine position ( / ˈ s uː p aɪ n / ) means lying horizontally with the face and torso facing up, as opposed to the prone position , which is face down. When used in surgical procedures, it grants access to

689-578: Is an emergency surgical procedure in which an incision is made through the cricothyroid membrane to establish a patent airway during certain life-threatening situations, such as airway obstruction by a foreign body, angioedema , or massive facial trauma. Cricothyrotomy is much easier and quicker to perform than tracheotomy, does not require manipulation of the cervical spine and is associated with fewer immediate complications. Some complications of cricothyrotomy include bleeding, infection, and injury to surrounding skin and soft tissue structures. A tracheotomy

742-735: Is clenched or if the patient is semiconscious and cannot tolerate an OPA. NPAs, however, are generally not recommended if there is suspicion of a fracture to the base of the skull . In these circumstances, insertion of the NPA can cause neurological damage by entering the cranium during placement. There is no consensus, however, regarding the risk of neurological damage secondary to a basilar skull fracture compared to hypoxia due to insufficient airway management. Other complications of Nasopharyngeal airways use includes laryngospasm, epistaxis, vomiting, and tissue necrosis with prolonged use. Oropharyngeal airways are curved, rigid plastic devices, inserted into

795-467: Is deemed necessary for safe transport of the patient, to reduce risk of failure and the associated increase in morbidity and mortality due to hypoxia. Management of the airway in the emergency department is optimal given the presence of trained personnel from multiple specialties, as well as access to "difficult airway equipment" ( videolaryngoscopy , eschmann tracheal tube introducer , fiberoptic bronchoscopy , surgical methods, etc.). Of primary concern

848-571: Is eating or drinking. Most modern protocols, including those of the American Heart Association , American Red Cross and the European Resuscitation Council , recommend several stages, designed to apply increasingly more pressure. Most protocols recommend first encouraging the victims to cough, and allowing them an opportunity to spontaneously clear the foreign body if they are coughing forcefully. If

901-461: Is frequently performed in the critically injured, those with extensive pulmonary disease, or anesthetized patients to facilitate oxygenation and mechanical ventilation . Additionally, implementation of a cuffing system is used to prevent the possibility of asphyxiation or airway obstruction. Many methods are used in Advanced airway management. Examples in increasing order of invasiveness include

954-557: Is limited evidence that the head down position can be used for self-treatment of suffocation and appears to be an option only if other maneuvers do not work. In contrast, in children under 1 it is recommended that the child be placed in a head down position as this appears to help increase the effectiveness of back slaps and abdominal thrusts. When the victim can not receive pressures on the abdomen (it can happen in case of pregnancy or excessive obesity, for example), chest thrusts are advised instead of abdominal thrusts. The chest thrusts are

1007-476: Is not possible, other surgical methods should be considered. Supraglottic techniques use devices that are designed to have the distal tip resting above the level of the glottis when in its final seated position. Supraglottic devices ensure patency of the upper respiratory tract without entry into the trachea by bridging the oral and pharyngeal spaces. There are many methods of subcategorizing this family of devices including route of insertion, absence or presence of

1060-815: Is not well established at this time given that the majority of studies on the topic are observational in nature. These studies, however, guide recommendations until prospective, randomized controlled trials are conducted. Current evidence suggests that for out-of-hospital cardiac arrest, basic airway interventions (head-tilt–chin-lift maneuvers, bag-valve-masking or mouth-to-mouth ventilations, nasopharyngeal and/or oropharyngeal airways) resulted in greater short-term and long-term survival, as well as improved neurological outcomes in comparison to advanced airway interventions (endotracheal intubation, laryngeal mask airway, all types of supraglottic airways (SGA), and trans-tracheal or trans-cricothyroid membrane airways). Given that these are observational studies, caution must be given to

1113-447: Is recommended in attempts to quickly secure an airway prior to progression of the swelling. Furthermore, blood and vomitus in the airway may prove visualization of the vocal cords difficult rendering direct and video laryngoscopy, as well as fiberoptic bronchoscopy challenging. Establishment of a surgical airway is challenging in the setting of restricted neck extension (such as in a c-collar ), laryngotracheal disruption, or distortion of

1166-596: Is said to be attributable to having babies sleep in the supine position. The realization that infants sleeping face down, or in a prone position, had an increased mortality rate re-emerged into medical awareness at the end of the 1980s when two researchers, Susan Beal in Australia and Gus De Jonge in the Netherlands, independently noted the association. It is believed that in the prone position babies are more at risk to re-breathe their own carbon dioxide . Because of

1219-703: Is suggested to be due, in part, to decreased no-flow-time in which vital organs, including the heart are not adequately perfused. Establishment of an advanced airway ( endotracheal tube , laryngeal mask airway ) allows for asynchronous ventilation, reducing the no-flow ratio, as compared to the basic airway ( bag-valve mask ) for which compressions must be paused to adequately ventilate the patient. Bystanders without medical training who see an individual suddenly collapse should call for help and begin chest compressions immediately. The American Heart Association currently supports "Hands-only" CPR , which advocates chest compressions without rescue breaths for teens or adults. This

1272-484: Is the condition and patency of the maxillofacial structures, larynx , trachea , and bronchi as these are all components of the respiratory tract and failure anywhere along this path may impede ventilation. Excessive facial hair, severe burns, and maxillofacial trauma may prevent acquisition of a good mask seal, rendering bag-valve mask ventilation difficult. Edema of the airway can make laryngoscopy difficult, and therefore in those with suspected thermal burns, intubation

1325-425: Is to minimize the reluctance to start CPR due to concern for having to provide mouth-to-mouth resuscitation . Airway represents the "A" in the ABC mnemonic for trauma resuscitation. Management of the airway in trauma can be particularly complicated, and is dependent on the mechanism, location, and severity of injury to the airway and its surrounding tissues. Injuries to the cervical spine, traumatic disruption of

1378-529: The gag reflex , it should only be used in a deeply sedated or unresponsive patient to avoid vomiting and aspiration. Careful attention must be made while inserting an OPA. The user must avoid pushing the tongue further down the patient's throat. This is usually done by inserting the OPA with its curve facing cephalad and rotating it 180 degrees as you enter the posterior pharynx. Extraglottic devices are another family of supraglottic devices that are inserted through

1431-859: The obtunded patient, or medical sedation. Airway obstruction can be caused by the tongue, foreign objects, the tissues of the airway itself, and bodily fluids such as blood and gastric contents ( aspiration ). Airway management is commonly divided into two categories: basic and advanced . Basic techniques are generally non-invasive and do not require specialized medical equipment or advanced training. These include head and neck maneuvers to optimize ventilation, abdominal thrusts , and back blows. Advanced techniques require specialized medical training and equipment, and are further categorized anatomically into supraglottic devices (such as oropharyngeal and nasopharyngeal airways ), infraglottic techniques (such as tracheal intubation ), and surgical methods (such as cricothyrotomy and tracheotomy ). Airway management

1484-427: The peritoneal , thoracic and pericardial regions; as well as the head, neck and extremities. Using anatomical terms of location , the dorsal side is down, and the ventral side is up, when supine. In scientific literature "semi-supine" commonly refers to positions where the upper body is tilted (at 45° or variations) and not completely horizontal. The decline in death due to sudden infant death syndrome (SIDS)

1537-595: The airway itself, edema in the setting of caustic or thermal trauma, and the combative patient are examples of scenarios a provider may need to take into account in assessing the urgency of securing an airway and the means of doing so. The pre-hospital setting provides unique challenges to management of the airway including tight spaces, neck immobilization, poor lighting, and often the added complexity of attempting procedures during transport. When possible, basic airway management should be prioritized including head-tilt-chin-lift maneuvers, and bag-valve masking. If ineffective,

1590-469: The airway tract and cause significant obstruction of the airway. Complete obstruction of the airway represents a medical emergency . During such crisis, caretakers may attempt back blows, abdominal thrust, or the Heimlich maneuver to dislodge the inhaled object and reestablish airflow into the lungs. In the hospital setting, healthcare practitioners will make the diagnosis of foreign body aspiration from

1643-400: The airways it may dislodge them further down the airways and thereby cause more blockage and harder removal. The head-tilt/chin-lift is the primary maneuver used in any patient in whom cervical spine injury is not a concern. This maneuver involves flexion of the neck and extension of the head at Atlanto-occipital joint (also called the sniffing position), which opens up the airway by lifting

1696-404: The airways, laparoscopic procedures and others due to its bulkier design and inferior ability to prevent aspiration. In these circumstances, endotracheal intubation is generally preferred. The most commonly used extraglottic device is the laryngeal mask airway (LMA). An LMA is a cuffed perilaryngeal sealer that is inserted into the mouth and set over the glottis. Once it is in its seated position,

1749-457: The cuff is inflated. Other variations include devices with oesophageal access ports, so that a separate tube can be inserted from the mouth to the stomach to decompress accumulated gases and drain liquid contents. Other variations of the device can have an endotracheal tube passed through the LMA and into the trachea. In contrast to supraglottic devices, infraglottic devices create a conduit between

1802-413: The device is gently inserted through a patient's nose after careful lubrication with a viscous lidocaine gel. Successful placement will facilitate spontaneous ventilation, masked ventilation, or machine assisted ventilation with a modified nasopharyngeal airway designed with special attachments at the proximal end. Patients generally tolerate NPAs very well. NPAs are preferred over OPAs when the patient's jaw

1855-460: The first year of injury are conflicting and show that shorter, less aggressive intervention is less effective. If therapeutic standing is to be incorporated into treatment, it should be more aggressive and initiated in the early stages of injury if any beneficial impacts on bone mineral density are hoped to be achieved. Standing devices are used in a variety of settings including: Funding (government funding or health insurance) for standing equipment

1908-464: The head in a dependent position so fluids do not drain down the airway, reducing the risk of aspiration. Most airway maneuvers are associated with some movement of the cervical spine . When there is a possibility of cervical injury, collars are used to help hold the head in-line. Most of these airway maneuvers are associated with some movement of the cervical spine. Even though cervical collars can cause problems maintaining an airway and maintaining

1961-443: The head of their bed up in a 30- or 45-degree angle. Airway management Airway management includes a set of maneuvers and medical procedures performed to prevent and relieve airway obstruction . This ensures an open pathway for gas exchange between a patient's lungs and the atmosphere. This is accomplished by either clearing a previously obstructed airway; or by preventing airway obstruction in cases such as anaphylaxis ,

2014-426: The immature state of their central chemoreceptors , infants do not respond to the subsequent respiratory acidosis that develops. Typical non-infants realize autonomic responses of increased rate and depth of respiration ( hyperventilation , yawning). Obstructive sleep apnea (OSA) is a form of sleep apnea that occurs more frequently when throat muscles relax and is most severe when individuals are sleeping in

2067-420: The medical history and physical exam findings. In some cases, providers will order chest radiographs, which may show signs of air-trapping in the affected lung. In advanced airway management, the inhaled foreign objects, however, are either removed by using a simple plastic suction device (such as a Yankauer suction tip ) or under direct inspection of the airway with a laryngoscope or bronchoscope . If removal

2120-430: The mouth to sit on top of the larynx . Extraglottic devices are used in the majority of operative procedures performed under general anaesthesia. Compared to a cuffed tracheal tube, extraglottic devices provide less protection against aspiration but are more easily inserted and causes less laryngeal trauma. Limitations of extraglottic devices arise in morbidly obese patients, lengthy surgical procedures, surgery involving

2173-435: The mouth, passing through the glottis, and into the trachea. There are many infraglottic methods available and the chosen technique is reliant on the accessibility of medical equipment, competence of the clinician and the patient's injury or disease. Tracheal intubation , often simply referred to as intubation , is the placement of a flexible plastic or rubber tube into the trachea to maintain an open airway or to serve as

2226-432: The oral cavity (for example, cutting a finger on jagged teeth). Prevention techniques focus on preventing airway obstruction by the tongue and reducing the likelihood of aspiration of stomach contents or blood. The head-tilt/chin-lift and jaw-thrust maneuvers are useful for the former while the recovery position is useful for the latter. If head-tilt/chin-lift and jaw-thrust maneuvers are performed with any objects in

2279-412: The patient's mouth. Oropharyngeal airways are produced in various lengths and diameters to accommodate for gender and anatomical variations. It is especially useful in patients with excessive tongue and other soft tissues. OPAs prevent airway obstruction by ensuring that the patient's tongue does not obstruct the epiglottis by creating a conduit. Because an oropharyngeal airway can mechanically stimulate

2332-554: The person's airway continues to be blocked, more forceful maneuvers such as hard back slaps and abdominal thrusts ( Heimlich maneuver ) can be performed. Some guidelines recommend alternating between abdominal thrusts and back slaps while others recommend the same starting with the back slaps first. Having the person lean forward reduces the chances of the foreign body going back down the airway when coming up. Performing abdominal thrusts on someone else involves standing behind them, and providing inward and upward forceful compressions in

2385-432: The possibility of confounding by indication. That is, patients requiring an advanced airway may have had a poorer prognosis in relation to those requiring basic interventions to begin with. For the management of in-hospital cardiac arrest however, studies currently support the establishment of an advanced airway. It is well documented that quality chest compressions with minimal interruption result in improved survival. This

2438-435: The posterior aspects of the mandible upwards while their thumbs push down on the chin to open the mouth. When the mandible is displaced forward, it pulls the tongue forward and prevents it from occluding the entrance to the trachea. The recovery position is an important prevention technique for an unconscious person that is breathing casually. This position entails having the person lie in a stable position on their side with

2491-509: The respiratory tract from gastric and nasal secretions, be easily inserted by even a nonspecialist, produce high first-time insertion rate, remain in place once in seated position, minimize risk of aspiration, and produce minimal side effects. A nasopharyngeal airway is a soft rubber or plastic tube that is passed through the nose and into the posterior pharynx . Nasopharyngeal airways are produced in various lengths and diameters to accommodate for gender and anatomical variations. Functionally,

2544-451: The same type of compressions but applied on the lower half of the chest bone (not in the very extreme, which is a point named xiphoid process and could be broken). The American Medical Association and Australian Resuscitation Council advocate sweeping the fingers across the back of the throat to attempt to dislodge airway obstructions, once the choking victim becomes unconscious. However, many modern protocols and literature recommend against

2597-421: The supine position. Studies and evidence show that OSA related to sleeping in the supine position is related to the airway positioning , reduced lung volume , and the inability of airway muscles to dilate enough to compensate as the airway collapses. With individuals who have OSA, many health care providers encourage their patients to avoid the supine position while asleep and sleep laterally or sleep with

2650-409: The tongue away from the back of the throat. Placing a folded towel behind the head accomplishes the same result. The jaw-thrust maneuver is an effective airway technique, particularly in the patient in whom cervical spine injury is a concern. It is easiest when the patient is positioned supine . The practitioner places their index and middle fingers behind the angle of the mandible to physically push

2703-453: The upper abdomen, concretely in the area located between the chest and the belly button. The rescuer usually gives the compressions using a fist that is grasped with the other hand. Abdominal thrusts can also be performed on oneself with the help of the objects near, for example: by leaning over a chair. Anyway, when the choking victim is oneself, one of the more reliable options is the usage of any specific anti-choking device. In adults, there

2756-476: The use of supraglottic devices such as oropharyngeal or nasopharyngeal airways , infraglottic techniques such as tracheal intubation and finally surgical methods. The ingestion and aspiration of foreign objects pose a common and dangerous problem in young children. It remains one of the leading cause of death in children under the age of 5. Common food items (baby carrots, peanuts, etc.) and household objects (coins, metals, etc.) may lodge in various levels of

2809-425: The use of the finger sweep. If the person is conscious, they should be able to remove the foreign object themselves, and if they are unconscious, a finger sweep can cause more harm. A finger sweep can push the foreign body further down the airway, making it harder to remove, or cause aspiration by inducing the person to vomit. Additionally, there is the potential for harm to the rescuer if they are unable to clearly see
