What is a portable pulse oximeter?
Portable pulse oximeter is a medical device used to measure blood oxygen concentration. In the hospital environment, the oximeter of the pulse can be a large piece of equipment capable of other measurements in addition to the oxygen concentration. The oximeter is often associated with a monitoring device to continuously monitor the patient's vital features. Someone who needs to measure the blood oxygen at home can use a portable pulse oximeter. These portable devices are small enough to fit into the bag or pockets and are as sensitive as hospital equipment. Low blood oxygen can indicate a serious health problem such as heart disease or circulatory disease. Pulse oximeters are often used in the hospital environment, as monitoring of blood oxygen is important for emergency medical care, during and after surgery and in intensive care situations. At home, a patient with heart, pulmonary or circulatory disease can wear a portable device for monitoring its blood oxygen. To is useful for people who have to use additional oxygen as a treatment.
Portable pulse oximeters work by measuring the wavelength of light issued from the patient's finger. A small sleeve is worn on the finger and the sleeve is connected to a portable unit that shows the measurement. The pulse oximeter is equipped with a sensor that emits red and infrared light and calculates how much light is absorbed compared to how much it is reflected. The device uses these measurements to calculate the amount of oxygen that is present in the blood circulating finger.
It works because hemoglobin, a protein molecule that carries the oxygen in the blood, absorbs the light of differentnuts when it carries oxygen. The portable pulse oximeter detects the reflection and absorption of red and infrared light and then calculates the ratio of oxygenated to deoxygenated hemoglobin. This measurement is then displayed on the digital device deduction.
Pulse oxymmetry is an indirect method of measurementblood oxygen. On the other hand, the use of blood oxygen levels is a direct way to measure the blood oxygen level. The use of a portable pulse oxymeter is a much more convenient and faster way to get this measurement, as the patient can wear this device at your fingertips and subtracts are carried out automatically. Portable pulse oximeters perform measurements in time with a heart rhythm of the wearer, which increases the accuracy of the hemoglobin ratio.
