Post-Extubation Stridor Risk Score

Calculate risk of post-extubation laryngeal edema requiring reintubation based on cuff leak volume, intubation duration, age, sex, and tube-to-trachea size ratio.

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.

How It Works

Calculate risk of post-extubation laryngeal edema requiring reintubation based on cuff leak volume, intubation duration, age, sex, and tube-to-trachea size ratio

Each component has a specific meaning:

  • Cuff leak volume — The cuff leak volume recorded for the scenario being assessed.
  • Intubation duration — The intubation duration recorded for the scenario being assessed.
  • Age — The age recorded for the scenario being assessed.
  • Sex — The sex recorded for the scenario being assessed.
  • Tube-to-trachea size ratio — The tube-to-trachea size ratio recorded for the scenario being assessed.

Note: Interpret the post-extubation stridor risk result against the thresholds and context described above.

How to Use

Enter the cuff leak volume, intubation duration, age, sex, tube-to-trachea size ratio for the scenario you are assessing. Calculate risk of post-extubation laryngeal edema requiring reintubation based on cuff leak volume, intubation duration, age, sex, and tube-to-trachea size ratio. Use the post-extubation stridor risk result to inform your calculation.
