The key difference between pulse flow and continuous flow in oxygen therapy lies in how oxygen is delivered to the user:
1. Pulse Flow: Breath of Efficiency
- Mechanism: Oxygen is delivered in bursts or pulses, triggered when the user inhales. The machine detects the user's breath and delivers a concentrated pulse of oxygen only during inhalation.
- Efficiency: More efficient in conserving oxygen, as it only supplies oxygen when needed, during inhalation.
- Portability: Pulse flow devices are generally more compact, lightweight, and suitable for portable oxygen concentrators (POCs).
- Use: Typically recommended for people with less severe oxygen needs, especially for those who are mobile or active. However, it may not be suitable for those who need oxygen while sleeping, as breathing patterns can change.
2. Continuous Flow: A Steady Stream of Support
- Mechanism: Oxygen is delivered continuously, regardless of whether the patient is inhaling or exhaling. This provides a steady stream of oxygen at a preset rate (e.g., 2 liters per minute).
- Efficiency: Less efficient in terms of oxygen conservation but provides constant support, which is necessary for certain conditions.
- Portability: Continuous flow machines are usually larger and less portable, often used for stationary home oxygen concentrators. However, some portable devices offer continuous flow but tend to be heavier.
- Use: Suitable for people who require a consistent and uninterrupted flow of oxygen, especially during sleep or when their oxygen needs are higher.
Which One to Choose?
- For portability and efficiency: Pulse flow is better for those who are active and need oxygen only during exertion or daytime activities.

- For high oxygen needs or night use: Continuous flow is preferred for users who need a steady supply of oxygen, such as those with more severe respiratory conditions or those who use oxygen while sleeping.

Both pulse and continuous flow systems have their advantages, and the right choice will depend on your specific oxygen needs and lifestyle.
Pulse flow is often preferred for portability and efficiency, especially for active individuals, while continuous flow is necessary for patients who require constant oxygen or need support while sleeping.
