Finding the Best Finger Pulse Oximeter
Pulse oximeter is a tool that measures oxygen in the blood. This tool is important because a person has to maintain a consistent supply of oxygen in order to function well. Medical experts use this tool to keep track of patients’ oxygen saturation during recovery treatment. Over the years, the way hospitals and medical professionals measure oxygen in the bloodstream has advanced from invasive, collecting blood sample and testing, to non-invasive methods using a finger pulse oximeter.
A finger pulse oximeter is easy to use and looks like a clip with sensors. It is normally clipped on the index finger. The sensor passes a light wavelength through the skin and detects oxygen levels in the bloodstream. It is used in recovery rooms, intensive care units, or even at home. These are small and read accurate oxygen levels. Some even have a heart rate reader included to track both oxygen and blood flow.
Choosing a Pulse Oximeter
Other than hospital use, a pulse oximeter can easily be owned for home use or athletic use. There are a number of these products in the market that caters to different needs. The best way to get a pulse oximeter is by going online and comparing available devices depending on your need and budget. Those with asthma use this to measure oxygen saturation in their blood. It helps them see how much their asthma allergy is affecting their oxygen supply. If you own a clinic, you might want to look for those pulse oximeters labelled for hospital use. Same goes if you want to use it for athletic purposes.
In choosing a pulse oximeter, consider your need for it and how it will help you. Although this tool can help you determine your oxygen saturation, it has limitations like it does not measure oxygen metabolism. It cannot detect how your body is using your oxygen supply. You may have 90% and above readings but it cannot detect if blood is circulating properly in your body. Try those with heart rate sensors to determine how your heart is distributing oxygen in your body.
