Question: 1 / 400

Describe the purpose of a laryngeal mask airway (LMA).

To secure the airway during intubation

To provide a clear airway for ventilation while minimizing trauma to the airway

The laryngeal mask airway (LMA) is designed specifically to provide a clear airway for ventilation while minimizing trauma to the airway. It sits above the larynx and creates a seal around the laryngeal opening, allowing for effective ventilation without the need for full intubation. This is particularly beneficial in situations where rapid airway management is required, as the LMA can be inserted quickly and easily, reducing the risk of trauma that may come with endotracheal intubation.

Its use often occurs in situations where a secure airway is needed but where traditional intubation may pose additional risks or challenges. The LMA is also less invasive than tracheal tubes, which contributes to its ability to minimize trauma, create a comfortable experience for patients, and allow for effective ventilation. Additionally, the LMA can be used in various patient populations, making it a versatile tool in the airway management toolkit.
