2017.1 : SAQ 2

Compare and contrast oxygen delivery via nasal cannulae (nasal prongs/specs), simple face mask (eg Hudson or CIG mask) and Venturi mask.

BT_SQ 1.14

A very practical question, understanding the physics of oxygen delivery by these different means will aid you in appropriate use.

 

Having an end-expiratory pause will affect the performance of the Hudson mask   TRUE/FALSE

Having a high peak inspiratory flow will affect the performance of nasal cannulae   TRUE/FALSE

Low flow rates may lead to an increased inspired pCO2 with the Hudson mask TRUE/FALSE

The Bernoulli effect is relevant for Venturi mask function   TRUE/FALSE

With nasal cannulae the nasopharynx acts as an oxygen reservoir   TRUE/FALSE
