<unk>  <unk>  is the highest level of<unk>  applied to the lungs during inhalation. In mechanical ventilation the number reflects a positive<unk>  in centimeters of water<unk>  (cmH2O). In normal breathing, it may sometimes be referred to as the maximal<unk><unk>  (MIPO), which is a negative value.<unk>  increases with any airway resistance. Things that may increase<unk>  could be increased secretions, bronchospasm, biting down on ventilation tubing, and decreased lung compliance.<unk>  should never be chronically higher than 40(cmH2O) unless the patient has acute respiratory distress syndrome.
