Cuff Leak Test for Post-Extubation Stridor Prediction

Calculate cuff leak volume (inspired VT minus expired VT with cuff deflated) to predict post-extubation laryngeal edema. Leak <110 mL or <12% of VT is associated with post-extubation stridor risk.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.
