Severe Atelectasis and Refractory Hyoxemia and Severe Systemic Hypotension

Severe Atelectasis with resultant Refractory Hypoxemia and Severe Systemic Hypotension … Mechanism of Action (MoA).

Understanding cardiac physiology 001 – unravel the heart

The traditional picture does not help in understanding cardiac physiology.


The cutaway heart does not help either.


It is important to unravel the heart and its vasculature.


And then, line the heart up in a unidirectional flow :


In a nutshell : the pulmonary circuit (vasculature) is shown in the diagram above.

Blood has to traverse the route of : RA > RV > pulmonary circuit > RA > RV (and then out the Aorta).
