The value of cough peak flow measurements in the assessment of extubation or decannulation readiness

Rev Port Pneumol (2006). 2015 Mar-Apr;21(2):94-8. doi: 10.1016/j.rppnen.2014.12.002. Epub 2015 Feb 14.


Insufficient cough strength has a major role in extubation and decannulation outcomes. Cough capacity can be easily evaluated by measuring flows during coughing. Values vary depending on whether cough flows are measured through the mouth or through a tracheostomy or endotracheal tube. It is important to standardize these measurements and start using them routinely in the extubation and decannulation processes. Values of cough peak flow >160 L/min measured at the mouth or a value of cough PEF >60 L/min measured at the endotracheal tube suggest successful decannulation or extubation.
