Cylinder Use Times
The pulse dose will vary on each individual's breathing patterns. The use time will vary depending on the patient's
prescription, breath rate and type of conserving device being used. All use times are calculated using a setting of 2 and
at a breath rate of 20-breaths per minute for pulse dose.
Respironics will offer both an oxygen conserving device (CHAD Therapeutics Bonsai) and two regulators (CHAD
Therapeutics 4800 and 3100) with our system package. The use times are calculated below:
