Even if the person who is being treated doesn’t seem to be having troubles breathing, finger pulse oximeters are still a good idea. However, in cases of breathing troubles or a fever, the use of these monitors is especially necessary. Patients with lung disorders, cancers, and other chronic illnesses may want to have finger pulse oximeters around to ensure that their blood is getting oxygenated. These devices are also helpful when you are heading out to a secluded area where you might not be able to access medical attention quickly. After purchasing a finger pulse oximeter, it's essential that you read the instructions which come with the device itself. Since each monitor is different, you will want to make sure you are using the oximeter correctly. In addition, you will need to make sure the finger pulse oximeter is securely fastened to the finger and that the finger is resting level with the body. What you may also want to keep in mind is that each person's version of 'normal' is different. So, if your blood oxygen level isn't as high as someone else's, this doesn't mean that something is wrong necessarily. Smokers, for example, tend to have lower oxygen saturation levels and those who are avid exercisers tend to have higher levels. Pulse Oximeters also come in different models and options:
