Adults are aware of the fact that their heart rate can be monitored, and sometimes this is necessary. Most also know how to measure their pulse in the conventional way by finding it in various parts of the body. Less commonly known is the meaning of oximetry, which is the way to determine how much oxygen the blood contains. Equipment has been designed to measure oxygen levels, such as the wrist pulse oximeter.
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.
Oximeters in the form of wristwatches are compact, but effective. They work in a similar way to those used at hospitals. Conveniently, they can remember data for up to eighty hours, at which time they will need to be cleared in order to be used again. The data can either be saved elsewhere, or removed from the device. These special oximeters are considered as safe to use by 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.
