Oxygen therapy is essential for many people with chronic respiratory conditions. Two common delivery methods are pulse dose and continuous flow, each with its own advantages depending on the patient’s lifestyle, needs, and oxygen prescription. Here’s what to know about how pulse dose vs. continuous flow oxygen systems work, their differences, and which may be a better fit for specific situations.
How Pulse Dose Oxygen Delivery Works
Pulse dose oxygen delivery provides oxygen only when the user inhales. A built-in sensor detects inhalation and triggers a short burst—or “pulse”—of oxygen. The device conserves oxygen by not delivering it during exhalation or between breaths. Pulse dose technology is often found in portable oxygen concentrators (POCs), like our DISCOV-R™ and X-PLOR® concentrators, and is designed for ambulatory use, meaning it’s ideal for those who want to stay active.
Pulse dose units are generally smaller and lighter than continuous flow systems, making them more convenient for travel, errands, and everyday activities outside the home. Pulse dose settings do not correspond directly to continuous flow liters per minute but are based on breath volume and frequency. This delivery method is efficient and helps extend battery life for mobile users.
How Continuous Flow Oxygen Delivery Works
Continuous flow oxygen delivery provides a constant stream of oxygen, regardless of the patient’s breathing pattern. The flow is measured in liters per minute (LPM), and the oxygen is delivered whether the user is inhaling or exhaling. This type of delivery is most often provided by stationary home concentrators or with oxygen tanks for patients who need a higher, consistent oxygen supply, but is available through our DISCOV-R portable oxygen concentrator so you can get back to doing the things you love.
Continuous flow is generally recommended for people who require oxygen during sleep, as pulse dose systems may not detect shallow nighttime breathing. It is also required for people who use oxygen with a CPAP or BiPAP machine, as these machines interfere with the inhalation sensor of pulse dose concentrators. This method is also preferred during certain medical procedures or for patients with high oxygen needs who are less active or bedbound.
Pros and Cons of Pulse Dose and Continuous Flow
Each delivery system has strengths and limitations. Pulse dose concentrators are lightweight, portable, and energy-efficient. They allow greater freedom and mobility but may not be suitable for users who need oxygen during sleep or those with very high oxygen requirements. Some users may also find pulse dosing less effective if they have irregular or shallow breathing patterns. Continuous flow systems are better suited for consistent, high-volume oxygen needs.
Choosing the Right Delivery Method
The right oxygen delivery method depends on multiple factors, including the prescribed flow rate, lifestyle, activity level, and whether the patient needs oxygen during sleep. For those who are active and mobile, a pulse dose system may be the better option. For users who need oxygen continuously, especially overnight or at higher flow rates, a continuous flow setup may be necessary. It’s important to follow medical guidance and undergo proper oxygen titration testing to ensure the system meets the user’s clinical needs.
