Quizplus · Accepted Answer

A Venturi mask is a medical device used to deliver a precise concentration of oxygen to a patient. It works by mixing oxygen with room air in a specific ratio to provide a precise concentration of oxygen to the patient. This is useful in patients with both hypoxia and hypercapnia, where a precise balance of oxygen and carbon dioxide is required. The mask does not provide positive pressure ventilation or a seal over the larynx to prevent aspiration. It also does not deliver a 100% concentration of oxygen.
