This simple to use photoelectric oximeter from Rova is well priced at £22.99 and sports a bright and easy to read OLED display and gives you an almost instant reading of your SpO2 levels – the oxygen saturation level of your blood – as well as your pulse on a bright and easy to read OLED screen. It also alerts you to abnormal readings and shows the pulse in graphical as well as numeric form. In the box are the Oximeter itself, together with a soft carry case, lanyard, User Guide and two AAA batteries.
There are no settings or configuration to worry about, all you need to know is to switch it on and put your finger into it to get an instant reading.
So what does it do?
It works by passing a beam of red and infrared light through a pulsating capillary bed in the fingertip below the nail. The ratio of red to infrared blood light transmitted gives a measure of the oxygen saturation of the blood. The oximeter detects the pulse and then subtracts the intensity of colour detected when the pulse is absent. The remaining intensity of colour represents only the oxygenated red blood. This is displayed on the electronic screen as a percentage of oxygen saturation in the blood.
The purpose of pulse oximetry is to check how well your heart is pumping oxygen through your body. It may be used to monitor the health of individuals with any type of condition that can affect blood oxygen levels. Normal Peripheral oxygen saturation readings should lie in the 85-100 range and the device will alert you if the reading is out of that range, although the device can be configured for custom alert levels.
I have no way of checking the accuracy of the results but equally have no reason to doubt them and found the readings to be as I expected and consistent.
The device is well made and has an attractive professional look to it as well as being both the fastest and easiest to use oximeter I have yet tried. The price is pretty much in line with rival products and the attractive design and the presentation makes it a very decent buy.
