Question

Of the devices listed below, which device is designed to deliver a more predictable FiO2?

A) Nasal cannula
B) Face mask
C) Shovel mask
D) Venturi mask

Answer 1

The Venturi mask is designed to deliver a more predictable FiO2 by allowing precise control of the oxygen concentration being delivered. This is achieved through the use of different color-coded adapters that correspond to specific FiO2 levels, allowing for accurate titration of oxygen therapy.

Step-by-step explanation:

Of the devices listed, the Venturi mask is designed to deliver a more predictable FiO2. Unlike other devices such as the nasal cannula or face mask, which rely on fixed flow rates to deliver oxygen, the Venturi mask has a built-in mechanism that allows for precise control of the oxygen concentration being delivered. This is achieved through the use of different color-coded adapters that correspond to specific FiO2 levels, allowing for accurate titration of oxygen therapy.
