The perfusion index can help you determine how appropriate the application site is it can help you find the best location to attach the pulse oximeter. Simply put, the stronger your pulse is at the monitoring site (where the pulse oximeter is attached), the more accurate the readings of it will be. The reason having a perfusion index on your pulse oximeter is a good idea is because it can help increase the accuracy of the readings which the pulse oximeter gives you in relation to your blood oxygen levels. Using the Perfusion Index with Pulse Oximeters In essence, the perfusion index is a measure of the strength of the pulse or the blood flow to a given area of the body, generally small extremities like toes, fingers, and ear lobes. Keep in mind that if you need a pulse oximeter with the perfusion index included, these extra sensors required to measure the perfusion index will also add more to the price of the pulse oximeter. With that said, most people who are in good health have no need for a pulse oximeter that includes the perfusion index, as a low perfusion index is usually associated with bad health. What is important to note is that pulse oximeter readings can be highly inaccurate if your perfusion index is too low, generally speaking, if your perfusion index is below or at 0.4%.ĭue to the lack of pulse, the pulse oximeter cannot accurately measure the amount of oxygen in the blood. The perfusion index can also be an indication of how reliable the reading from the pulse oximeter is. This is then expressed as a percentage which ranges from 0.02% to 20%. The perfusion index is calculated by dividing the pulsatile signal (AC) by the non-pulsatile signal (DC), multiplied by 100.
The most widely used monitoring tool to keep track of the perfusion index is the pulse oximeter. This might all sound very complicated, but what it really means is that the perfusion index measures the strength of the pulse at the site where the sensor is connected, which in this case is the pulse oximeter.
The perfusion index represents the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in the peripheral tissues and limbs, such as toes, finger tips, and ear lobes. Using the Perfusion Index with Pulse Oximeters.Buy a fingertip oximeter in Canada online from BIOS Medical today. We accept payment via PayPal, GPay, and ShopPay. These two devices also check pulse rate and oxygen saturation.īIOS Medical is a pulse oximeter manufacturer in Canada. They are the Fingertip Pulse Oximeter and Fingertip Pulse Oximeter – Blue. The BIOS Diagnostics Fingertip Pulse Oximeter checks your pulse rate and the oxygen saturation of arterial hemoglobin (SP02). All pulse oximeter devices are suitable for adult and pediatric use. What types of pulse oximeters are on offer?įor a fingertip oximeter in Canada, BIOS Medical has the best options for home use. If the pulse oximeter detects a drop in oxygen saturation, medical intervention might be needed. When the lungs struggle to transport oxygen into the blood, blood oxygen saturation declines. The heart then pumps it through the rest of the body via arteries, including to the organs. These capillaries send oxygen-rich blood to the heart. When we breathe, our lungs transmit oxygen into our capillaries. Our organs need a constant supply of oxygen to work properly. Why is it important to know what the oxygen saturation of my lungs is? With this measurement, the device calculates the blood oxygen saturation. On the other side of the finger, a sensor detects and measures the amount of light passing through the finger without getting absorbed by the blood and tissue. When activated, it emits a light that passes through the fingernail, skin, blood, and tissue. The small digital device is clipped onto the fingertip and covers the front and back of the fingertip. Pulse oximetry is non-invasive and painless. All the devices are Health Canada approved. Need a pulse oximeter in Canada to measure your oxygen saturation at home? As a pulse oximeter manufacturer, BIOS Medical offers three fingertip devices to use in the home setting.
