If you have been told by your doctor that you need to keep an eye on the level of oxygen in your blood, you are probably in the market for an oxygen monitor. You can find these pulse oximeters for sale in many different locations. They are available at pharmacies or from medical supply companies or from online stores. It may surprise you to find that you might find your best deal by shopping online. We have some tips on evaluating pulse oximeter price and effectiveness below.
To begin with, you should understand that some of these devices are relatively cheap. You can buy one for around $29 on the low end. However, those lower end models may not be as durable or as reliable or accurate as a unit that costs just a bit more. If your life depends on this reading, you will want to make sure that you are buying a quality unit. Your doctor can probably provide you with specific recommendations, but you can also make sure that whichever unit you choose, it is an FDA approved unit. This means that it is certified to meet certain standards regarding accuracy so you can rest easier on that account if you buy such a unit. A unit of this type might cost more in the range of $90 or so.
You will, of course, want to use the unit according to your doctor’s recommendations. Otherwise, you can just follow the directions. The unit works by slipping it onto the end of your finger. When you turn it on, it shines a red and an infrared light through the tip of your finger. The machine takes a reading how much and what type of light is penetrating through your flesh. This is helpful because the blood that is carrying oxygen blocks a specific wavelength of light, whereas blood that is not bound to oxygen blocks a different part of the spectrum.
Keeping Track of Your Blood Oxygen Level
If you have reason to monitor the level of oxygen in your blood on a daily basis or even more frequently, you will probably want to use a home finger oximeter. This is a little device that slips on the end of your finger and tells you whether your blood is carrying enough oxygen. You can find these oximeters for sale at many different retailers, including both online shops and bricks and mortar shops such as Target. However, you may want to do some research before you make a purchase to make sure that you are buying a quality item.
You can read reviews of specific models on Amazon. People who have bought these items write reviews telling you how accurate and how well constructed the items are. If an item is flimsy, they will definitely let you know. It is much better to get advice from actual customers than just relying on the promotional material supplied by the manufacturer because average consumers will tell you what they really think in an unbiased way. To get even more reassurance that you are buying a quality product, you can search for an FDA approved oximeter only.
To use the oximeter, you simply slide it on the end of your finger and turn it on. It works by shining a light through your fingernail. The light is measured as it comes out the other side, and then the little computer in the device is able to calculate what percent of your blood that is flowing through your arteries is carrying oxygen as it should. You will want to follow the advice of your doctor because there is no way for an article of this nature to cover all the reasons that you might be short of oxygen, so make sure your doctor provides you with clear instructions.
