Table 2 Prevalence of asynchrony in enrolled patients and among different classifications of brain injury
From: Patient–ventilator asynchrony in acute brain-injured patients: a prospective observational study
Type of asynchrony | All patients (n = 100) | Types of brain injury | P* | ||
|---|---|---|---|---|---|
Stroke (n = 44) | Post-craniotomy (n = 37) | Traumatic brain injury (n = 19) | |||
