How to Choose The Right Flow Rate

How to Choose the Right Flow Rate (5 LPM vs 10 LPM) for Oxygen Therapy

When it comes to oxygen therapy , one of the most common questions people have is — what flow rate is right for me: 5 LPM or 10 LPM? Choosing the correct oxygen concentrator flow rate is essential for effective treatment, comfort, and energy efficiency.

In this article, we’ll explain the difference between 5 LPM and 10 LPM concentrators, and help you decide which one best suits your needs.

Understanding LPM (Litres Per Minute).

LPM (litres per minute) refers to the amount of oxygen delivered to the patient each minute.

• 5 LPM concentrators are designed for moderate oxygen needs.
• 10 LPM concentrators provide higher oxygen output and are ideal for patients with severe respiratory conditions or those requiring dual-user setups.

Your doctor or pulmonologist will prescribe the right oxygen flow based on your SpO₂ levels, oxygen saturation test results, and overall health condition.
