Minute ventilation

Calculate the patient's minute ventilation thresholds.

Please enter the baseline minute ventilation and click the 'Calculate' button. The values in the outlined boxes will show the lower and upper thresholds based on the low and high threshold percentages. Simply slide the percentage values to calculate different threshold levels. You can also adjust the threshold values, which will update the percentage value. Click the 'Reset' button to reset the values and start again.

Cylinder duration with oxygen blender module (OBM)

Calculate OBM cylinder depletion for passive circuit configurations

Important: Please review the following conditions before using this calculator. The duration tables presented below may return non-applicable and/or null values if these conditions are not observed.

  • Use only positive integers in the entry fields
  • The starting pressure should be less than the nominal charge pressure of the cylinder i.e. it’s not possible for a cylinder to contain a pressure higher than its nominal charge pressure
  • Starting pressure should be greater than zero
  • Starting pressure should be greater than the ending pressure
  • Ending pressure should be greater than zero
