It is important to use oxygen at the flow rate that has been prescribed. Never increase or decrease the flow rate without first consulting your child’s doctor.
If you care for a child or baby who needs oxygen therapy as part of their respiratory care, there are a number of important things you should know.
Low flow concentrators are available for children and babies. These deliver oxygen at much lower flow rates to a standard concentrator (flow rate settings for Millennium Paediatric concentrator: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 lpm).
Your child’s concentrator will be locked at the prescribed flow rate by your Air Products technician. Any further adjustments should only be undertaken on the recommendation of your doctor. However, if your child has been prescribed a variable flow rate, you will need to adjust the flow rate and relock the machine.

Note
The flow of oxygen is very low. If you are concerned the concentrator is not delivering any oxygen, place the end of the supply hose onto some water and check for bubbles.
When your Air Products technician first installs your child’s equipment, you will be offered a piped oxygen system. This will allow your child to use oxygen in more than one room without the need to move the oxygen concentrator.
For more information download our > leaflet [PDF 92 KB]Portable oxygen cylinders are filled with oxygen to help you and your child go out and do everyday things. To set the flow rate of oxygen for your child from the oxygen cylinder, it may have been fitted with a flowmeter.

How long your child’s oxygen cylinder lasts is based on the type of oxygen cylinder you are using and the flow rate setting.

B10 Paediatric - this is the largest paediatric cylinder available fitted with a flowmeter to make it suitable as a long lasting backup supply for paediatric patients. Note: the cylinder is white to distinguish it from the standard black B10.
The duration of this oxygen cylinder varies depending on the type of flowmeter being used and the litres per minute (flow rate).
Fixed with a low flowmeter this oxygen cylinder will last from 1 day, 14 hours (at 0.9 litres per minute) to 14 days, 16 hours (at 0.1 litres per minute)
Fixed with a micro flowmeter, this oxygen cylinder will last from 16 days (at 0.09 litres per minute) to 147 days (at 0.01 litres per minute)

Caution:
It is very important to use the oxygen cylinder at the flow rate that has been prescribed. Never increase or decrease the flow rate without first consulting your child’s doctor or respiratory specialist.
Your child’s oxygen mask and cannula are important pieces of oxygen equipment.
A cannula can become easily blocked by nasal excretions and mucus. Both masks and cannulae should therefore be kept as clean as possible.

You should also check oxygen tubing daily for any obvious signs of damage such as kinking, flattening or splitting. If you notice any damage, replace the tubing immediately.
It is important to keep spare masks and cannulae to hand at all times. If you are running short, please call our Homecare Service Helpline on 0800 373 580 between 8.00am and 5.30pm and we will send you more by post.
Take care that tubing does not become trapped, e.g. in furniture, doors, babies’ cots, infants’ high chairs etc as this will restrict, or even stop, the flow of oxygen.
