Most people know that their pulse, or heart rate, can be measured, and that this measurement may be necessary for several medical reasons. During a general check up at the doctor, your heart rate will most likely be determined to see if it is normal. Oximetry is the medical term used to describe the measurement of how much oxygen is within the blood at any given time. For this purpose, the wrist pulse oximeter has been developed.
Oximeters are equipment with various designs, and mostly they are found in large health institutions, such as hospitals. Nurses and doctors will use them in the critical care units and in the emergency department of the facility; and possibly in other areas as well. However, people also need the device outside of a hospital, and this is why they have been created in the form of a wristwatch. They will be needed when someone is in danger of their oxygen levels falling below an acceptable range.
The oximeters that can be used at home are of a convenient size, and are easy to operate. They are also quite reliable, and are able to store information for more than three days. You will just need to clear the device of stored data when the memory is full, otherwise it will not work. If you are considering buying a medical device such as this one, you can feel rest assured that it is safe to use, as it has been accepted under the requirements of the FDA.
The wristwatch oximeters are usually used on one's finger, but on the earlobe or on a toe are common places too. The device does not hurt in any way, as it is non-invasive, and works with red and infrared lights. They are ideally bought by people who wish to monitor their levels of oxygen during sleep, study or exercise, or because they have asthma.
A small amount of the light is not absorbed by the skin and surrounding tissue, and highlights the hemoglobin within. The device will give a reading in percentage form, which can be between ninety-five and ninety-eight percent in a healthy person. This percentage may also drop lower at times, or for some people due to various reasons, but under ninety percent is considered problematic. Oxygen will then need to be provided so that the body cells can function, and so that the patient can breathe normally.
Oximeters give quite accurate readings, but there are certain things that cause unreliable readings. There must be a strong pulse rate in order for the device to work. Patients who have an irregular heartbeat will not be able to get an accurate reading. A patient will also struggle if they have a very weak heart rate.
Furthermore, the accuracy of the device is hindered by movement, as it affects the way the light is produced. The person being tested must remain still. The device works with light, and therefore the presence of other bright lights could affect its reliability. Since that oximeters can produce results that are inaccurate, several readings should always be taken.
The wrist pulse oximeter is equipped with a long-lasting battery, and can be used with various software programs that are readily available. The device can also be used when you are wearing nail polish, regardless of the color. They are usually purchased with at least a year warranty.
