About

Cough Peak Flow (CPF) seems to be an efficient tool to assess cough capacity for the intensive care unit (ICU) ventilated patient. CPF can be used in the ventilator weaning process, as reflecting the upper airways protection capacity.

CPF requires disconnection of the patient from the ICU ventilator, supplemental material (handheld spirometer, antibacterial filter) and an excellent synchronization between the specialized caregiver and the patient.

We aimed that CPF with the ventilator built-in flow-meter is correlated with CPF using a handheld flowmeter connected to the endotracheal tube.

cough peak flow measurement

Description:

All enrolled patients will undergo measurement of cough peak flow by two methods, i.e. using a handheld electronic spirometer, and using the ventilator flowmeter, in a randomized order.
