Bestsellers for Oximeters
Pulse oximetry is a non-invasive method used to measure the oxygen saturation level in the blood. However, certain conditions can cause false readings. These include poor circulation, cold extremities, and nail polish or artificial nails. Additionally, movement and ambient light can also interfere with the readings. Lastly, carbon monoxide poisoning can also give a false reading as pulse oximeters cannot differentiate between oxygen and carbon monoxide.
Understanding Pulse Oximetry
Pulse oximetry is a simple, non-invasive method of monitoring the level of oxygen carried in the body. This type of measurement is known as oxygen saturation or SpO2. A sensor device is placed on a thin part of the patient's body, usually a fingertip or earlobe, or in the case of infants, across a foot. The pulse oximeter measures light absorption of oxygenated (bright red) and deoxygenated (dark red/purple) blood in the patient's body to determine oxygen saturation.
Factors Affecting Pulse Oximetry Readings
Several factors can affect the accuracy of pulse oximetry readings. For instance, poor peripheral circulation can result in inaccurate readings. This is because blood flow to the extremities can be reduced under certain conditions, such as hypothermia or in patients with certain vascular diseases. In such cases, the pulse oximeter may not receive a strong enough signal to provide an accurate reading.
The Impact of Cold Extremities on Pulse Oximetry
Cold fingers or toes can cause vasoconstriction, which means less blood flows to these areas. This can make it difficult for the pulse oximeter to detect a pulse and measure the oxygen saturation level accurately. Warming up the hands or feet before taking a reading can help improve accuracy.
Nail Polish and Artificial Nails: A Barrier to Accurate Readings
Nail polish, especially dark colors, and artificial nails can absorb some of the light emitted by the pulse oximeter, leading to inaccurate readings. If possible, the sensor should be placed on a finger without nail polish or artificial nails.
The Effect of Movement and Ambient Light
Excessive movement can cause the pulse oximeter to give inaccurate readings due to the movement of blood. Similarly, ambient light, particularly bright sunlight, can interfere with the sensor's ability to detect changes in light absorption. Therefore, it is recommended to minimize movement and avoid direct sunlight when taking a reading.
Carbon Monoxide Poisoning: A Hidden Danger
Carbon monoxide (CO) binds to hemoglobin in red blood cells much more readily than oxygen does, forming carboxyhemoglobin. Unfortunately, pulse oximeters cannot differentiate between carboxyhemoglobin and oxyhemoglobin. Therefore, in cases of carbon monoxide poisoning, the pulse oximeter may show a normal oxygen saturation level, leading to a potentially dangerous false reading.
