The Laryngeal Mask Airway (LMA) is a medical device used to manage the airway during anesthesia or resuscitation. This is a type of supraglottic airway device that sits above the glottis, allowing air into the lungs. The LMA is classified as a non-invasive airway device, which means it does not require any invasive procedures to insert.

The LMA is commonly used in emergency situations, such as when a patient cannot be intubated or when there is a risk of aspiration. It can also be used as an alternative to endotracheal intubation in certain surgical procedures, such as laparoscopic surgery.

There are different types of LMAs available, including reusable and disposable options. They come in various sizes to accommodate different patient populations, from neonates to adults.

Overall, the LMA is a useful tool for managing the airway in a safe and effective manner. Its non-invasive nature and ease of use make it a valuable device in emergency situations and in certain surgical procedures where endotracheal intubation may not be feasible.
