Spontaneous Breathing Trial Readiness

Assess readiness for a spontaneous breathing trial (SBT) using standard ICU criteria: hemodynamic stability, oxygenation, mental status, and resolution of acute illness.

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

Assess readiness for a spontaneous breathing trial (SBT) using standard ICU criteria: hemodynamic stability, oxygenation, mental status, and resolution of acute illness

Each component has a specific meaning:

  • Standard ICU criteria: hemodynamic stability — The standard icu criteria: hemodynamic stability recorded for the scenario being assessed.
  • Oxygenation — The oxygenation recorded for the scenario being assessed.
  • Mental status — The mental status recorded for the scenario being assessed.
  • Resolution of acute illness — The resolution of acute illness recorded for the scenario being assessed.

Note: Interpret the sbt readiness result against the thresholds and context described above.

How to Use

Enter the standard ICU criteria: hemodynamic stability, oxygenation, mental status, resolution of acute illness for the scenario you are assessing. Assess readiness for a spontaneous breathing trial (SBT) using standard ICU criteria: hemodynamic stability, oxygenation, mental status, and resolution of acute illness. Use the sbt readiness result to inform your calculation.
