Which is not an obvious advantage of high pressure oxygen through cannula:
(A) Bypassing nasopharyngeal dead space (B) Decreases need for intubation (C) PEEP (D) Hot and Humidification of air
(A) High pressure oxygen through cannula: Oxygen supply system capable of delivering up to 100% humidified and heated oxygen at a flowrate of up to 60 liters per minute. This device increases the FiO2 (21-100%) and reduces the need for intubation. It also creates some amount of PEEP: 3-5mmhg
