4.6.11 APRV (Airway Pressure Release Ventilation)

Airway ventilation and pressure release: this type of
ventilation features two positive pressure levels.

The system displays all PRP relative to the set
operative mode.
APRV is a spontaneous ventilation mode with constant positive pressure on 2 different
levels, during which the lung ventilator keeps the two pressure levels set constant.
In this operative mode the patient is free to breath spontaneously inside the circuit but at a
pressure greater than the atmospheric one, with increased residual functional capacity. The
User can set on the lung ventilator the pressure of the two levels and the relative times.

LOW LEVEL pressure - LOW level TIME

HIGH LEVEL pressure - HIGH level TIME
During spontaneous breathing the pressure value varies around the set value, it tends to
drop when the patient inhales and to rise when the patient exhales. If during spontaneous
breathing the patient does not reach the airway low pressure limit (LOW PAW), after 20
seconds the system enables the relative alarm.
