Tidal Volume

494 mL

Ideal Body Weight70.5 kg
Respiratory Rate14 breaths/min
Minute Ventilation6.92 L/min
Suggested PEEP5 cmH₂O
Initial FiO₂100%
How to Use This Calculator
  1. Enter the patient's weight in kg and height in cm.
  2. Select patient sex to compute predicted body weight for lung-protective ventilation.
  3. Choose ventilator mode (e.g., volume control, pressure control).
  4. Review the suggested tidal volume (6 mL/kg PBW), respiratory rate, and PEEP.
  5. Adjust settings based on arterial blood gas results and clinical response — physician oversight required.

How the result changes with Height (cm)

Height (cm)Tidal Volume

142284 mL
178512 mL
208702 mL

What each input means

Patient Weight (kg)
Actual body weight. Ideal body weight is calculated from height.
Height (cm)
Patient height used to calculate ideal body weight for tidal volume.
Gender
1 = male, 2 = female. Affects ideal body weight calculation.
Ventilation Mode
1 = volume control, 2 = pressure control, 3 = SIMV.

What each result means

Tidal Volume
Based on 7 mL/kg ideal body weight (lung-protective).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Patient Weight (kg) = 75, Height (cm) = 175, Gender = 1, Ventilation Mode = 1 = 4 input(s) provided
  2. Calculate Tidal Volume
    Tidal Volume
    494 = 494
  3. Calculate Ideal Body Weight
    Ideal Body Weight
    70.5 = 70.5
  4. Calculate Respiratory Rate
    Respiratory Rate
    14 = 14
