Guaranteed Tidal Volume with Volume Control Ventilation

Patient transport with MEDUMAT Easy<sup>CPR</sup>

Volume control ventilation defines the volume administered to the patient (tidal volume Vt as the control variable). Airway pressure results from the compliance of the lungs and the inhaled volume. One of the most common volume controlled ventilation modes is IPPV (Intermittent Positive Pressure Ventilation).

The IPPV mode is used for mandatory, volume control ventilation with a fixed tidal volume and fixed frequency. This mode is used on patients who have no spontaneous respiration. However, a spontaneously breathing patient can breathe deeply and freely during expiration.

Once the maximum ventilation pressure (pMax) has been reached, the device maintains the pMax until the end of the inspiratory time and then switches to expiration. It is therefore possible that the set tidal volume will not be fully applied if the maximum ventilation pressure (pMax) has been reached during inspiration.

The following ventilation parameters can be set:

Vt: Tidal volume (breathing volume) in ml
Freq.: Ventilation rate in bpm
pMax: Maximum inspiratory pressure in cmH2O

The volume-controlled IPPV ventilation mode is included in:
