Portable concentrator machines

A portable concentrator machine is a small device that can give mobility outside the home and is designed to work on pulse dose delivery. It has the ability to use mains, battery and DC power supply.

Portable concentrator machines are not suitable for everyone, a specific ambulatory assessment should be completed by your Healthcare Professional before one is ordered.

Your flow setting on a portable concentrator machine may vary from what you require using a standard concentrator machine or oxygen cylinder. It is important that you use the flow rate requested by your Healthcare Professional, and only change this if you are instructed to by them and shown how to by our Healthcare Technician.
