Cuffed oropharyngeal airway
WebA face mask, a cuffed oropharyngeal airway, or an LMA were placed in each patient in a random sequence. After 15 minutes of spontaneous breathing through each of the airways, ventilatory variables, as well as arterial, end-tidal, and mixed expired CO2 partial pressure, were measured, and physiological dead space/tidal volume ratio was calculated. WebThe mechanism of sealing comprises an airway with a pharyngeal cuff that seals at the base of the tongue; it consists of a simple cuff surrounding a tube. Here, the forces that achieve an effective seal are approximately perpendicular to the direction of the airway channel and the direction of potential airway expulsion.
