PCV (ventilation mode)

from Wikipedia, the free encyclopedia

PCV is pressure controlled ventilation ( pressure-controlled ventilation ) and a controlled ventilation mode in the medicine . It is pressure-controlled, so only up to the maximum pressure set in the ventilator is ventilated, optionally a lower limit can also be set, the so-called PEEP (positive end expiratory pressure). Depending on the patient's compliance, this then results in the individual tidal volume (volume that is supplied to the patient with each breath). It results from the formula V = C * p. V = volume, C = compliance and p = pressure. Sufficient ventilation of the lungs and thus the alveoli is only guaranteed if the tidal volume is large enough.

As an alternative to this pressure-controlled ventilation mode, there is the volume-controlled VCV mode ( volume controlled ventilation ).
