What are the supraglottic airway devices?

Supraglottic airways (SGAs) are a group of airway devices that can be inserted into the pharynx to allow ventilation, oxygenation, and administration of anesthetic gases, without the need for endotracheal intubation.

What are the different types of airway devices?

The five types include:
  • Facemask ventilation devices, which may use additional attachments.
  • Supraglottic airway devices.
  • Tracheal intubation.
  • Suction machines for airway clearance.
  • Transtracheal access.

How many types of LMA are there?

Laryngeal mask airways come in several types, as follows: The LMA Classic is the original reusable design. The LMA Unique is a disposable version, making it ideal for emergency and prehospital settings. The LMA Fastrach, an intubating LMA (ILMA), is designed to serve as a conduit for intubation.

What is difference between LMA and Igel?

Laryngeal mask airway (LMA) Classic™ has an inflatable cuff while i-gel™ has a noninflatable cuff made of thermoplastic elastomer.

What are the 5 P’s for intubation?

The sequential process for quickly intubating a patient in an emergency situation is referred to asrapid-sequence intubation. The steps in performing RSI are often described by the six “P’s”: preparation, preoxygenation, pretreatment, paralysis and induction, placement of the tube, and postintubation management (Fig.

Is an OPA a supraglottic airway device?

In roughly increasing order of invasiveness are the use of supraglottic devices such as oropharyngeal (OPA), nasopharyngeal (NPA), and laryngeal mask airways (LMA). Laryngeal mask airways can even be used to deliver general anesthesia.

Why is the Igel better than the LMA?

I-gel is a simple device which is easy to insert without much of manipulations rapidly. It has a potential advantage of effective seal pressure which is less as compared to LMA-Proseal, but is enough to prevent aspiration and maintain an effective ventilation and oxygenation.

When should you not use Igel?

  1. Responsive patient with intact airway –protective reflexes.
  2. Patients with known esophageal disease.
  3. Caustic ingestions.
  4. Upper-airway obstructions due to foreign bodies or pathology.
  5. Trismus, limited mouth opening, airway abscess, trauma or mass.

What type of airway is an Igel?

Abstract. The i-gel, invented by Muhammed Aslam Nasir, is a new supraglottic airway, consisting of a mask and a tube. One notable feature of the i-gel is that the rim of the mask is designed to conform to the anatomical shape of the larynx. This enables the device to provide an airtight seal without the cuff mechanism.

When are airway devices used?

10-8, A). The oral airway device is primarily used to alleviate upper airway obstruction caused by tonsillar or adenoidal hypertrophy, or normal pharyngeal tissue obstruction, as often occurs in small infants (see Chapter 3, Respiratory Physiology).

What is an example of an advanced airway?

Advanced Airway

Examples are supraglottic devices (laryngeal mask airway, laryngeal tube, esophageal-tracheal) and endotracheal tube.

What is an oral airway used for?

An oropharyngeal airway (oral airway, OPA) is an airway adjunct used to maintain or open the airway by stopping the tongue from covering the epiglottis. In this position, the tongue may prevent an individual from breathing.

Why is Ambu bag used?

A bag valve mask (BVM), sometimes referred to as an Ambu bag, is a handheld tool that is used to deliver positive pressure ventilation to any subject with insufficient or ineffective breaths. It consists of a self-inflating bag, one-way valve, mask, and an oxygen reservoir.

Is an LMA an advanced airway?

The laryngeal mask airway (LMA) is an advanced airway alternative to ET intubation and provides comparable ventilation. It is acceptable to use the LMA as an alternative to an esophageal-tracheal tube for airway management in cardiac arrest.

Is an Igel an advanced airway?

Advanced airway equipment protects the airway during CPR to ensure that rescue breaths don’t cause negative secondary effects, like vomit aspiration. The i-gel is a simpler, faster, and safer supraglottic airway device.
