Cough strength predict extubation outcomes of patients who have passed a spontaneous breathing trial (SBT) (1,2)
The two groups of patients according to the peak expiratory flow (PEF), were similar regarding age, APACHE II, underlying chronic disease and duration of mechanical ventilation before extubation
No significant differences were found between the prophylactic devices of assistance at risk group of extubation failure
Summary
Weak cough was defined by peak expiratory flow (PEF) < 60 L/min. The patients with PEF>60 L/min conventional oxygen therapy was applied, and groups at risk of extubation failure (PEF< 60 L/min) was applied prophylactic noninvasive ventilation (vni) [BiLEVEL/CPAP mode] vs humidified high-flow nasal cannula (HFNC) randomly. Extubation failure was defined as the need of reintubation within 48 h following extubation We compared both groups of patients according to the PEF, and prophylactic assistance on groups patients with weak cough, on outcome extubation. Continuous variables were expressed as mean ± SD or median (IRQ) and categorical variables as absolute value and percentage. The comparison of continuous variables was performed by Student t test and Mann-Whitney test and comparison between categorical variables was performed by Fisher’s exact test and Chi-square test
