Pulse flow: check with the doctor first
- This machine gives oxygen in pulses when the patient breathes in. It does not give continuous flow.
- Pulse flow is not right for every patient, for example during sleep or for patients prescribed a continuous flow. Ask the patient’s doctor before buying.
- Keep it away from flames, smoking and heat, and charge the battery as the manual says.
Who it is for
Patients whose doctor has approved pulse-flow oxygen and who want oxygen while travelling or away from home. Always follow the patient’s doctor on the settings and type of equipment.
