Merlin Finger Pulse Oximeters

These are a range of lightweight finger clip oximeters that can be carried in your pocket or handbag.

They measure SpO², Pulse Rate & Pleth Waveform - in other words they measure both pulse rate and the arterial oxygen saturation of hemoglobin at the peripheral capillary level in your finger.

They can be used on infants, children and adults.

If you have covid, these devices should tell you quickly whether your breathing difficulties are getting dangerous, so that you can call an ambulance.
