Adjusting the respiratory rate on a mechanical ventilator can be used to adjust a patient's PaCO2.
(1) current respiratory rate in breaths per minute
(2) current PaCO2 in mm Hg
(3) desired PaCO2 in mm Hg
target respiratory rate in breaths per minute =
= (current PaCO2) / (desired PaCO2) * (current respiratory rate)
• It is assumed that there is no change in tidal volume.
• The minute volume is the tidal volume in L times the respiratory rate.
• The target respiratory rate may need to be ROUNDed to an integer.
