What are the airway devices?

What are the airway devices?

Supraglottic airway devices (SADs) are used to keep the upper airway open to provide unobstructed ventilation. Early (first-generation) SADs rapidly replaced endotracheal intubation and face masks in > 40% of general anesthesia cases due to their versatility and ease of use.

What is a medical airway?

1. A natural passage for air to enter and exit the lungs. 2. A device to prevent or correct an obstructed respiratory passage, esp. one inserted into the trachea and used during anesthesia or cardiopulmonary resuscitation.

When are airway devices used?

For anesthesia, these devices are used for primary airway management, for rescue ventilation when facemask ventilation is difficult, and as a conduit for endotracheal intubation.

What are the two types of airways?

Types of airway include:

  • oropharyngeal.
  • nasopharyngeal.
  • endotracheal.
  • laryngeal mask airway.
  • cricothyroidotomy.
  • tracheostomy.

What is face mask ventilation?

Mask ventilation is a straightforward, noninvasive technique for airway management that can be used as a primary mode of ventilation for an anesthetic of short duration or as a bridge to establish a more definitive airway.

How do you use an airway device?

The tube is inserted blind into the patient’s mouth and guided over the tongue until resistance is encountered. The tube can then be connected to a ventilation device and airway patency confirmed with chest movement, fogging of the tube and a CO2 trace.

What is a ventilator machine?

A ventilator is a machine that helps you breathe when you’re sick, injured, or sedated for an operation. It pumps oxygen-rich air into your lungs. It also helps you breathe out carbon dioxide, a harmful waste gas your body needs to get rid of.

What is airway management techniques?

Basic airway management involves the use of non-invasive techniques without the need for specialized medical equipment. Examples include chest compressions, abdominal thrusts, and back blows, all of which may be used independently or in combination to relieve foreign body airway obstruction.

Which laryngoscope is most commonly used?

The most common laryngoscope blade used for intubation in adults is the curved Macintosh blade (Figure 34-4). This is inserted into the right side of the mouth to displace the tongue laterally. The tip of the blade sits in the vallecula and is lifted forward to elevate the epiglottis and expose the laryngeal inlet.

What is advanced airway device?

Advanced airway management is the subset of airway management that involves advanced training, skill and invasiveness. It encompasses various techniques performed to create an open or patent airway – a clear path between a patient’s lungs and the outside world.

What is basic airway management?

Basic airway management are a set of medical procedures performed in order to prevent airway obstruction and thus ensuring an open pathway between a patient’s lungs and the outside world.

What are airway structures?

The upper airway consists of the nose, pharynx, epiglottis, and larynx. The upper airway structures protect the lower airway from foreign materials, and warm, filter, and humidify inspired air. Lower airway structures include the trachea, left and right mainstem bronchi, segmental bronchi, and terminal bronchioles.

What is an oral airway device?

An oropharyngeal airway (also known as an oral airway, OPA or Guedel pattern airway) is a medical device called an airway adjunct used to maintain or open a patient’s airway. It does this by preventing the tongue from covering the epiglottis, which could prevent the person from breathing.
