Pressure Time Product (PTP)

FluxMed respiratory monitors are the only monitors that calculate the pressure time product (PTP) breath by breath. The PTP quantifies the patient’s effort.

According to ATS and ERS recommendations on the evaluation of the respiratory muscles: the PTP, be it expressed for each breath or by minute, is the best tool for measuring the respiratory effort of ventilated patients (ATS/ERS Statement on Respiratory Muscle Testing, page. 613).

The PTP allows for the calculation of the patient’s effort on the three areas it comprises. One area corresponding to the patient’s resistive effort and two to the elastic one. The elastic effort is divided between the PEEPi-associated effort (intrinsic PEEP or AUTO PEEP) and the effort not associated to PEEPi, the thoracic-pulmonary elastic effort.
