Oxygen is integral in the survival of any human being. As such, it is but important to maintain the level of oxygen in the body for it to function well and survive. To do this, oxygen levels in a person's body is monitored through the use of a medical device called pulse oximeter. It is the small device attached on the fingernail or the earlobe that will determine the oxygen's saturation level in the blood. Normal readings are between 95 to 100 percent, below those readings, a person must seek the physician's medical attention.
In hospitals, a pulse oximeter is normally connected to a TV monitor so doctors can check the status of the person. Although normally used at hospitals, pulse oximeters are fairly easy to use that even people that do not have any medical background can perform them if they know how to follow instructions. With this, pulse oximeters used at home are made available in the market now. If you want to buy one to monitor you or a family member's level of blood oxygen, here are some tips that you should know to buy the right one.
Firstly, you should know that there are different types of pulse oximeters. The larger oximeter is used at hospitals. Smaller ones on the other hand are used at home and are made portable. They are used for transportation and for people who are engaging in strenuous exercises and people who are at risk of having low levels of oxygen.
Then it is also important to note that there are now pulse oximeters that are specifically designed for children. They are smaller that will fit on a child's finger for more accurate readings. So if you need a oximeter for a child, then make sure to buy one that is designed for children.
Pulse oximeter also differs in prices so it is important to know how much you are willing to spend for one. Some costs at least some few hundred bucks while others can go as high as a couple hundred dollars. What you should know is that an oximeter that has a higher price does not necessarily mean that it is the better option. What you should take note of is an oximeter that gives the right readings and pulse rates.
Lastly, make sure that the oximeter is easy and simple to use. You do not need a very sophisticated device that will only make it hard for you to use it. Choose one that you can easily understand. Likewise, you can also check for online tutorials and information that will help you know the basics of getting a pulse oximeter reading.
