Use of bacteria fiters in the expiratory side of the patient circuit can cause an undesirable increase in breathing resistance. Particularly when nebulizing aerosols or humidifying the breathing gas, resistance caused by a bacteria filter may slowly increase, leading to increased work of breathing and to intrinsic PEEP.

  • Page 132 Synchronization of mandatory ventilator breaths by itself effectively reduces SIMV time, which would result in an undesirable increase in the effective IMV rate. Savina therefore extends the subsequent time allowed for spontaneous breathing by the missing time difference ∆T – thus preventing an increase in SIMV rate.

  • Page 134 Theory of Operation PCV+ (BIPAP) PCV+ (BIPAP) Pressure Controlled Ventilation plus Biphasic Positive Airway Pressure PCV+ is a pressure controlled/time cycled ventilation mode which allows the patient to breathe spontaneously at any time. PCV+ is therefore often described as a time cycled alternation between two CPAP levels.
