Comparative Study
A pilot study to investigate any relationship between sustained maximal inspiratory pressure and extubation outcome.
To establish whether any relationship exists between extubation outcome and sustained maximal inspiratory pressures (SMIP). ⋯ In this study, peak MIP was not specific enough to be clinically useful as a predictor of extubation outcome. SMIP was associated with extubation outcome with equally high sensitivity and specificity and may therefore have a role in outcome prediction.
