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.
The reason why oximeters may be used is when someone's oxygenation is unstable. They are a device that are mostly found in various departments of hospitals. They are common in emergency rooms, and in intensive and critical care rooms. However, oximeters have also been developed that are ideal for home usage, as they fit around a patient's arm, and look just like a wristwatch.
Wristwatch oximeters are not cumbersome in any way, and have all the features of a hospital's unit. They have a memory of possibly up to eighty hours, which means that every reading can be stored. However, when the memory is full, the information must first be deleted or transferred before the device will work again. These wristwatch devices have been approved for usage by the FDA.
Persons who would like to monitor their heart rates and their oxygen levels at home, while they study or while they sleep, will find these devices ideal. Persons who would like to monitor their asthmatic condition may consider using them as well. Oximeters, including the wristwatch variety, have a non-invasive probe that produces red and infrared light. They are usually shined onto a finger, toe or earlobe.
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.
The patient who requires the test should also not be moving around, as motion could cause the device to give an unreliable response. The light is disturbed by movement. The device should not be used around other very bright lights, as this could effect its own light. One reading is often not sufficient to determine an accurate level of oxygen.
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.
