Plateau Pressure Safety Limit (<=30 cmH2O)

Measure plateau pressure during an inspiratory hold (0.5-2 sec pause at end-inspiration) to assess alveolar overdistension risk. Goal <= 30 cmH2O per ARDSNet protocol. Values > 30 cmH2O require tidal volume reduction or other interventions.

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. Measure plateau pressure during an inspiratory hold (0.5-2 sec pause at end-inspiration) to assess alveolar overdistension risk. Goal <= 30 cmH2O per ARDSNet protocol. Values > 30 cmH2O require tidal volume reduction or other interventions. Use the plateau pressure result to inform your calculation.
