As lung protective strategy you prefer volume control or pressure control ventilator mode?!
The choice of ventilation mode dependen on the patients condition.I prefer PC mode.
There might be no significant difference in the PC and VC mode when the decreation square is used.
Pressure control mode offers better lung protection if other factors remain same.
Depends on what you want to protect. PC protects from high pressures, and if you accept some permissive hypoxemia regarding a low tidal volume, it is a good choice.
PC protects from high airway pressure. Lung damage comes from high trans-alveolar pressure, which may happen if there is a large inspiratory effort (ie, Pmus adds to Paw). We are talking about simple, set-point targeting of PC modes. You could choose to use adaptive targeting in PC (eg, PRVC or VC+ modes). It all depends on what your goal is. There are only 3 goals of ventilation, safety (gas exchange and lung protection), comfort (patient-ventilator synchrony), and liberation (minimize time on vent). The choice of mode, not just PC vs VC depends on your assessment of the patient's need and hence your clinical goal. There is a rational approach to selecting modes. See attached paper.
Pressure control mode with careful titration of volume would be better option for effective ventilation.
Pressure Control One Lung Ventilation (PCV-OLV) reduces peak airway pressures and may have a small effect on plateau pressures.
