Fingertip pulse oximeters

The fingertip pulse oximeters are small, portable medical devices that use light-based technology to measure oxygen saturation levels in the blood. They attach to the tip of a person's finger or earlobe, allowing a small light source to pass through tissue and measure the amount of oxygen in the blood. The device then displays the oxygen saturation levels on a digital display.

Fingertip pulse oximeters are an important tool for monitoring oxygen levels in the blood. They are non-invasive devices, meaning they don't require needles or other invasive procedures. It is a quick and easy way to monitor blood oxygen levels and detect any changes in oxygen saturation levels. 

Using a fingertip pulse oximeter is relatively simple. First, place the device on the fingertip or earlobe of the person being monitored. Make sure that the light source is pointed toward the tissue and that the device is securely fastened. Once the device is in place, turn the device on and wait for the oxygen saturation levels to appear on the display. It is important to ensure that the device is in the correct position and that the readings are accurate. Avoid painted fingernails and frozen limbs to avoid incorrect readings.

Normal blood oxygen values range from 94% - 100%, and in cases where the pulse oximeter reads below 90%, it is necessary to consult your doctor.
