Varies from 21% (room air) to 100% with > 50-60% considered toxic (reactive oxygen species, free radical formation etc). Respiratory rate as set on the ventilator (patient will receive at least these many breaths/min but can spontaneously breathe above this set rate) 1:4, with obstructive lung disease or high airway resistance) A typical ratio is 1:2 (may need to be much greater, i.e. Generally, expiration takes longer than inspiration. If I time is set at 1 second, then E time is necessarily 2 seconds For example, a respiratory rate of 20 breaths/min means each breath is 3 seconds. Generally not directly set but determined by the set rate and inspiratory time. during a spontaneous pressure support breath) during control breath, or determined by the patient, i.e. Time spent in inspiration (can be set, i.e. Volume of gas entering the patient's lung during inspiration The pressure applied to the lungs never drops below this value. Pressure maintained at the airways at the end of expiration. Sum of PEEP and IP (in a pressure control mode) Total pressure delivered (used to overcome both respiratory system compliance as well as airway resistance).
