Spontaneous Awakening Trial (SAT) Criteria Checker

Evaluates safety criteria for spontaneous awakening trials (SAT) in mechanically ventilated ICU patients. Safety screen PASS criteria: off sedation or low infusion, no agitation (RASS ≤2), SpO2 >88%, RR <35/min, pH >7.25, FiO2 ≤0.70, PEEP ≤10 cmH2O. FAIL criteria: active seizures, alcohol withdrawal, elevated ICP, open abdomen, ongoing NMB. SAT followed by SBT improves extubation rates and reduces ICU LOS.

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 to Use

Enter the values for the scenario you are assessing. Evaluates safety criteria for spontaneous awakening trials (SAT) in mechanically ventilated ICU patients. Safety screen PASS criteria: off sedation or low infusion, no agitation (RASS ≤2), SpO2 >88%, RR <35/min, pH >7.25, FiO2 ≤0.70, PEEP ≤10 cmH2O. FAIL criteria: active seizures, alcohol withdrawal, elevated ICP, open abdomen, ongoing NMB. SAT followed by SBT improves extubation rates and reduces ICU LOS. Use the sat criteria result to inform your calculation.
