II. Indications

  1. Patient height must be at least 60 inches (5 feet) or 152.4 cm for these Ideal Body Weight calculations

III. Calculation: Male Predicted Body Weight (PBW, using Devine Formula)

  1. Ideal Weight (Devine, 1974), Predicted Body Weight (PBW) used in ARDS-NET Tidal Volume calculation
    1. Weight (kg) = 50 + 2.3 * (htIn - 60)
    2. Weight (kg) = 50 + 0.91 * (htCm - 152.4)
  2. Alternative PBW estimates
    1. Ideal Weight (Robinson, 1983)
      1. Weight (kg) = 52 + 1.9 * (htIn - 60)
    2. Ideal Weight (Miller, 1983)
      1. Weight (kg) = 56.2 + 1.41 * (htIn - 60)
    3. Ideal Weight (Hamwi, (1964)
      1. Weight (kg) = 48.0 + 2.7 * (htIn - 60)
    4. Ideal Weight (Approximate quick calculation, modified from Broca's Index, 1871)
      1. Weight (lb) = 106 + 6 * (htIn - 60)
  3. Calculated Male Predicted Body Weights (PBW, using Devine Formula)
    1. Ht 155 cm: 52 kg
    2. Ht 160 cm: 57 kg
    3. Ht 165 cm: 61 kg
    4. Ht 170 cm: 66 kg
    5. Ht 175 cm: 71 kg
    6. Ht 180 cm: 75 kg
    7. Ht: 185 cm: 80 kg
    8. Ht: 190 cm: 84 kg
    9. Ht: 195 cm: 89 kg
    10. Ht: 200 cm: 93 kg
    11. Ht: 205 cm: 98 kg

IV. Calculation: Female Predicted Body Weight (PBW, using Devine Formula)

  1. Ideal Weight (Devine, 1974), Predicted Body Weight (PBW) used in ARDS-NET Tidal Volume calculation
    1. Weight (kg) = 45.5 + 2.3 * (htIn - 60)
    2. Weight (kg) = 45.5 + 0.91 * (htCm - 152.4)
  2. Alternative PBW estimates
    1. Ideal Weight (Robinson, 1983)
      1. Weight (kg) = 49 + 1.7 * (htIn - 60)
    2. Ideal Weight (Miller, 1983)
      1. Weight (kg) = 53.1 + 1.36 * (htIn - 60)
    3. Ideal Weight (Hamwi, (1964)
      1. Weight (kg) = 45.5 + 2.2 * (htIn - 60)
    4. Ideal Weight (Approximate quick calculation, , modified from Broca's Index, 1871)
      1. Weight (lb) = 100 + 5 * (htIn - 60)
  3. Calculated Female Predicted Body Weights (PBW, using Devine Formula)
    1. Ht 155 cm: 48 kg
    2. Ht 160 cm: 52 kg
    3. Ht 165 cm: 57 kg
    4. Ht 170 cm: 62 kg
    5. Ht 175 cm: 66 kg
    6. Ht 180 cm: 71 kg
    7. Ht: 185 cm: 75 kg
    8. Ht: 190 cm: 80 kg
    9. Ht: 195 cm: 84 kg
    10. Ht: 200 cm: 89 kg
    11. Ht: 205 cm: 93 kg
