Oxygen Therapy – Pulse Dose vs. Continuous Flow


Each respiratory patient has different criteria for what they need from their oxygen equipment and concentrators. When it comes to oxygen delivery, two methods are considered the standard:

  • Pulse Dose
  • Continuous Flow

Each of these delivery methods has its purpose and benefits, so how do you know which oxygen delivery method is right for you? At Hart Medical, we are driven by service excellence and our goal is to work with you and your doctor to find the right oxygen equipment to meet your needs. Part of that responsibility is making sure you understand the benefits of each type of oxygen delivery system.

What is Pulse Dose Delivery?

Pulse dose oxygen delivery is customized to the way you breathe, it is breath initiate and how fast the oxygen is delivered is based on how often you breathe. This ensures that no oxygen is wasted and that you are only using the oxygen as you need it. Pulse dose delivery concentrators are a great option for time spent outside the home or when traveling. While pulse dose oxygen delivery can be a great convenience, it is not the best therapy for everyone. You may need continuous flow to keep your oxygen levels in a safe range.

What is Continuous Flow Delivery?

Continuous flow oxygen delivery is not breath initiated and provides a continuous flow of oxygen. With a continuous flow oxygen concentrator, oxygen is delivered at the same rate and does not change depending on your breathing rate. Continuous flow home oxygen concentrators tend to be heavier, which makes it more difficult to use them when you are traveling. There are portable oxygen concentrators that provide a continuous flow option, so you can still enjoy traveling while getting the oxygen delivery you need.

How Do I Choose My Oxygen Delivery Method?
