The wrist pulse oximeter is a device that is used to find out the levels of oxygen in a person's blood at any time of the day or night, and is ideal for personal use. It also measures the heart rate of a patient. These facts sometimes need to be known for various reasons that relate to someone's health.
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.
Oximeters for home use are most often purchased by persons who need to keep a constant track of their oxygenation percentage. This could be necessary during times of rest, or because they suffer from asthma. The device works with a probe that does not penetrate the skin, and that normally fits over someone's finger. It shines red and infrared light.
The light that is shined onto the skin is mostly absorbed by tissue, but some is not, and it is this small amount of light that is used to show the level of oxygen in the blood, or the hemoglobin levels. An individual in good health will be expected to get a reading of between 95% and 98%. It will rarely be at 100%. However, for some people it could be normal that the percentage is anything down to 90% as well. Below this percentage, the patient may be having trouble breathing.
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.
It is not recommended to use oximeters under strong lights, and the patient will have to be as still as possible when the reading is taken. Movement, as well as bright lights, could cause the device to give an unreliable percentage. Since that a few factors could cause discrepancies, a sole reading is insufficient.
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.
