Frequently Asked Oxygen Concentrator Questions

General / Operational:

1. What is Pulse Flow and how is it different from Continuous Flow ?

  • Answer: Pulse and continuous flow (or pulse dose and continuous flow dose) refer to how the oxygen is delivered to the patient. A pulse flow machine delivers oxygen only when the patient inhales and is triggered by inhaling. A continuous flow machine delivers a continuous flow of oxygen. Most continuous flow machines will deliver BOTH pulse and continuous flow.

2. Can I use pulse dose at night when I sleep ?

  • This is a question that should be answered by your doctor. Most doctors recommend continuous flow for sleeping.
