Overview
Brief Summary
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.

Outcomes
Primary Outcomes
Correlation coefficient for the two CPF assessment methods, on extubation day
Time Frame: Within 1 hour before mechanical ventilation termination (extubation)
Correlation coefficient for the two CPF assessment methods, on extubation day
Secondary Outcomes
- 3. Correlation between the two CPF assessment methods the days before extubation(During the mechanical ventilation until 72 hours post extubation)
- Assess the correlation between CPF and length of mechanical ventilation(During the mechanical ventilation until 72 hours post extubation)
- Discriminatory power of CPF to predict successful weaning of mechanical ventilation, i.e. no reintubation within 72 hours after extubation, or unsuccessful weaning.(During the mechanical ventilation until 72 hours post extubation)
