WebOct 12, 2024 · However, measuring cough peak flow with an external flowmeter requires a dedicated device. This may limit the use of this method. As the AUC was 0.77 when cough peak flow was measured with a ventilator, indicating moderate accuracy for predicting extubation failure, it can be used to predict extubation failure if an external flowmeter is ... WebFeb 1, 2024 · In fact, the expiratory flow bias for secretion movement would favor a slow rise time (ie, low inspiratory flow), in opposition of the findings reported by Chatwin and Simonds. 10 This is further supported by the work of Lancombe et al, 19 which suggests that the time spent above a cough peak flow that causes secretion movement is more ...

WebIntroduction. Both percentages of predicted forced expiratory volume in 1 second (FEV 1) and peak expiratory flow rate (PEFR) are widely used to estimate the degree of pulmonary impairment in patients with COPD. 1–3 In general, FEV 1 measurements by spirometry are preferred as it is much more reproducible. 4 However, spirometry is not widely available, … WebBackground: Cough efficacy assessment is of clinical relevance in neuromuscular patients. Tests of varying complexity and invasiveness, such as cough peak flow (CPF), maximal expiratory pressure (PEmax) and gastric pressure …
WebMay 1, 2024 · Cough strength is strongly associated with re-intubation; patients with a weak cough are more likely to experience re-intubation. 5,9–20 Cough peak flow (CPF) is commonly used to reflect cough strength because it is an objective measurement.
