Abstract:
The nasal positive pressure oxygenation device, SuperNO2VA™ (Vyaire Medical™), represents a significant advancement in airway management and perioperative care, particularly in patients at high risk for hypoxemia. This paper traces the historical development, underlying technology, and clinical adoption of the device, emphasizing its role in improving patient outcomes. By addressing gaps in traditional airway management and leveraging innovative design, the SuperNO2VA™ device has become a useful tool in modern anesthesiology.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
