Pulse oximetry is a measurement method used on patients to monitor O2 saturation in blood. This monitoring is done using a recording pulse oximeter. The gadget monitors and records any changes in the degree of oxygen concentration in blood cells and alerts the doctor. Notification can be in form of a sound and only happens when the level falls too low. Early medical intervention can therefore be done following the alerts.
The principle of pectrophotometry is the one these gadgets base on in their working. This principle is in turn reliant on how deoxygenated and oxygenated blood cells absorb red and infrared light. The sensor records these rates of absorption and passes the values to the main machine to be processed. The machine processes and gives new values after every of 0.5-1 seconds. High accuracy is ensured by this high rate.
The gadget comprises of two light emitting diodes that emit infrared and red radiations. When in use, the diodes must be placed directly opposite to their respective detectors. The detectors and the diodes should then be separated by 5-10 mm of tissue. This is why an oximeter must be placed on an organ with thin tissues like an earlobe or fingertip. Sensors of the device are made into clips or wraps. Recent studies show that oxygen saturation inside the body cannot be measured effectively through earlobes.
These devices can be employed in all medical settings where it is important to monitor blood oxygen saturation in patients. Major facilities in which they are used include treatment wards, recovery wards, operation rooms, intensive care, and emergency units. Accuracy of recorded values can be achieved by the patient staying in a calm position. Devices with recording function are better because they keep a record of values for a given period for future use.
Besides determining oxygen saturation in blood cells, oximeters can be used in many other situations. First, blood gas analysis may be replaced with oximetry except in situations where PaCO2 or acid-base state is needed. When compared to other techques, oximetry is less painful, costs less, and is simpler to perform. In cases where the patient is conscious, this method has a high level of accuracy. Recorded values are used as standards and can be utilized in determining variations.
Oximeters also prevent wastage of oxygen supplied to patients by keeping usage only to required levels. Intrapartum fetal monitoring and neonatal care are the other areas of usage. Use in neonatal care and intrapartum fetal monitoring are not developed and standardized fully but soon they will. First aid in modern ambulances is provided by these devices. GP kits are progressively getting equipped with oximeters.
In primary care, these gadgets are useful in the diagnosis and management exacerbation of COPD in places. This method can also be employed in grading severity of asthma attacks. An attack is said to life-threatening if the reading falls below ninety two percent. Oximetry can also be used to assess and care for bronchiolitis in kids.
The capability of recording oximeters to record readings raises their prices above those of other models. Costs are dictated by the number of additional functionalities in the gadget. Purchases may be made from shops that sell medical apparatus.
