We can put a certain volume of air into the patient with each breath in mechanical ventilation
We can put air into the patient until the pressure reaches a certain value.
We can decide how often we give the patient a breath each minute, or how often the patient is initiating their own breath each minute, or a combination of the two.
In other words the oxygen concentration we give to the patient, from 21% (room air) to 100%.
Maximum pressure in the proximal airway at the end of inspiration
Equilibrium pressure reached if the expiratory tubing is occluded at the end of inspiration. It is a surrogate for end-inspiratory alveolar pressure
Do we have the patient decide when they want to breathe, or do we have the ventilator decide when to initiate a breath. Or indeed a combination of the two? Is it ventilator controlled or patient controlled?
