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