Predicted body weights

The mantra of "low tidal volume" in ARDS is based on predicted body weight. This is a calculation based on age, gender and height.

Predicted body weight for men:

50 + (2.3 x [height in inches - 60])
or
50 + (0.91 x [height in centimeters - 152.4])

.

Predicted body weight for women:

45 + (2.3 x [height in inches - 60])
or
45 + (0.91 x [height in centimeters-152.4])
