Evaluation of peak cough flow in Brazilian healthy adults
UNLABELLED INTRODUCTION In this study we aimed to evaluate the peak cough flow (PCF) in healthy Brazilian subjects. METHODS We evaluated 484 healthy subjects between 18 and 40 years old. Subjects were seated and oriented were asked to perform a maximal inspiration followed by a quick, short and explosive expiration on the peak flow meter. Three measures were carried out and recorded the av...
متن کاملCough peak expiratory flow. assistance at extubation and outcomes
Methods Prospective collected database was conducted from December 2014 to April 2015. Weak cough was defined by peak expiratory flow (PEF) < 60 L/min. The PEF was measured with Cosmed Pony Graphic spirometer v.4.0 S-CZ before extubation, for the patients mechanically ventilated >24 h, who passed successfully SBT at least of 30 min of pressure support 5-8 cmH2O, CPAP, or T-T. The patients were ...
متن کاملCoughing correlates: insights into an innovative study using cough peak expiratory flow to predict extubation failure
Main text We read the innovative study by Duan et al. [1] with great interest. However, key results need to be interpreted carefully to reach the proper conclusions. First, their primary finding that patients with low cough peak expiratory flow (CPEF) have significant benefit from non-invasive positive pressure ventilation (NIPPV) in the prevention of re-intubation and 90-day mortality is not u...

متن کاملTowards a quantitative description of asthmatic cough sounds.
This study describes a method of quantitatively characterizing cough sounds using digital signal processing techniques. Differences between asthmatic and non-asthmatic cough sounds are presented. Coughs from 12 asthmatic and 5 non-asthmatic subjects were analysed. Cough sounds and flows were digitized, at a sampling rate of 5 kHz, before and after a free-running exercise test. Individual coughs...
