  1. LAWP: leak airway pressure, defined as the lowest peak airway pressure at which air leakage was detected. LCP: leak cuff pressure, defined as the highest cuff pressure at which air leakage was detected. When leakage was not detected, the highest peak airway pressure or the lowest cuff pressure studied was defined as LAWP or LCP, respectively
  2. The values are reported as median and (range). N = 5 for the experiments with ID 40 mm and N = 10 for those with ID 5.0 mm
