Cough Peak Flow Assessment Without Disconnection From the ICU Ventilator in Mechanically Ventilated Patients.

ABSTRACT:

Background

Because ICU ventilators incorporate flow velocity measurement, cough peak expiratory flow (CPF) can be assessed without disconnecting the patient from the ICU ventilator. Our goal was to estimate the correlation between CPF obtained with the built-in ventilator flow meter (ventilator CPF) and CPF obtained with an electronic portable handheld peak flow meter connected to the endotracheal tube.

Methods

Cooperative mechanically ventilated patients who entered the weaning process and who were ventilated with pressure support < 15 cm H₂O and PEEP < 9 cm H₂O were eligible for the study. Their CPF measurements obtained on the extubation day were kept for analysis.

Results

We analyzed CPF obtained in 61 subjects. The mean ± SD value of ventila
