Verified Answer
With reference to the pulse oximeter, consider the following statement...
The UK government’s Department of Health and Social Care announced that an independent review will be carried out to find out if there is a potential bias in medical items such as pulse oximeters and how they impact patients from various ethnic groups.
- This move comes amid rising concerns that many medical devices are designed and calibrated for white patients.
- why is the device racist? The initial step in an oximeter is the light passing through your skin and most of these devices are calibrated for light skin and can give errors for nonwhite people.
Working
- A pulse oximeter is a small clip-like device used to calculate the amount of oxygen in your blood. It can be attached to the fingertip, earlobe or toes.
- The oximeter has a small electronic processor and a pair of LEDs – one emitting red light and another infrared. The oximeter shines these two lights which pass through your finger and the device senses what comes through the other side.
- Our blood contains haemoglobin and when it is saturated with oxygen it is called oxygenated haemoglobin and is bright red in colour. The hemoglobin without oxygen is called deoxygenated haemoglobin.
- Oxygenated haemoglobin and deoxygenated haemoglobin absorb red and infrared light differently. Oxygenated haemoglobin absorbs more infrared light and allows more red light to pass through than deoxygenated haemoglobin.
- The amount of light that is transmitted is measured by the processor and the device displays the oxygen saturation or the percentage of oxygenated haemoglobin in your blood.
Hence only statement 1 is correct.
