Both PVC and silicone laryngeal masks are supraglottic airway ventilation tools with the same purpose: general anesthesia, emergency care, and simple ventilation. Their structures are basically the same: mask body, ventilation tube, inflation bag, and connector. However, they differ in materials, comfort, temperature characteristics, and usage scenarios. Similarities and differences between PVC and silicone laryngeal masks 1

As one of the three core tools of modern airway management, the silicone laryngeal mask fills the gap between face masks and endotracheal tubes, serving as a first-line alternative for difficult airway emergencies and a key device for balancing infection control and cost. It belongs to the supraglottic airway ventilation category, used to establish a temporary artificial airway during general anesthesia and emergency situations. It does not enter the trachea but only conforms to the pharyngeal cavity.

Although anesthesia masks and oxygen masks appear similar and are both classified as basic respiratory-assist medical consumables—serving as indispensable, essential equipment for emergency care, the perioperative period, and the management of cr...

The primary function of the tracheal tube cuff is to seal the airway and secure the tube in place. It ensures an airtight seal during mechanical ventilation and prevents the aspiration of oropharyngeal secretions or gastric contents into the lungs,...
