During the pressure trigger ventilation the minute ventilation was greater than that in the flow triggering ventilation without affecting the other ventilatory parameters.

N Engl J Med ; About this article Cite this article Correa, T. Grippi MA. Physiological effects of flow and pressure triggering during non-invasive mechanical ventilation in patients with chronic obstructive pulmonary disease. Patients and methods: One hundred patients with acute respiratory failure of pulmonary origin were assigned randomly to two groups: 50 patients ventilated with PT and 50 patients ventilated with FT.
Much of the difference between pressure and flow triggering during CPAP is. There was also a significant difference between patients for deltaP, deltaT, and PTP for each trigger method (p<). For this group of patients, flow triggering.
Of these, time pressure and flow triggers are the most common. detect a difference between inspiratory (Vin) and expiratory (Vout) flow rates.
