Pulse oximeter JPD-500F.
A pulse oximeter is a device recommended for health monitoring during a pandemic. The fingertip pulse oximeter monitors blood oxygen saturation (SpO2) and pulse.
Indispensable during the Covid 19 pandemic.
A pulse oximeter is especially important for people who have the coronavirus with little or no symptoms. It should be a mandatory part of the home first aid kit during the pandemic. The device is small, so you can always have it at hand. A pulse oximeter measures vital signs in a non-invasive manner within seconds.
Who is the pulse oximeter intended for?
People staying in home quarantine, people who suspect the possibility of infection, seniors, people with reduced immunity, people with respiratory disorders, asthmatics, people with cardiovascular problems, people who want to check their vital functions.
How to use an oximeter.
Insert your finger into the device (fingertip down).
Press the button to start the measurement.
Wait 5-7 seconds for the result.
The range of saturation in healthy people is between 93 and 99%.
The heart rate range is 60-90 beats per minute.
Interpretation of results.
Saturation equal to or higher than 95% - adequate level.
Saturation 90-95% - monitor your saturation level.
Saturation below 90% - risk of hypoxia - contact your doctor. 
Saturation below 80% - hypoxia - urgent medical help.
Saturation below 70% - risk of loss of consciousness.
CE certificate.
The pulse oximeter is a medical device with a CE certificate (certificate of conformity) issued by an authorized EU notified body: TÜV SÜD PRODUCT SERVICE GMBH RIDLERSTR 65, D-80339 MÜNCHEN, GERMANY
