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.
Spectrophotometry is the main principle that the working of these gadgets bases on. This principle is dependent on the mode of absorption of red and infrared radiation by deoxygenated and oxygenated blood cells. These rates of absorption are recorded by the sensor and passed to the main machine for processing. The main machine gives fresh values at intervals of 0.5 or 1 seconds after processing. This high rate ensures high accuracy.
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.
Oximeters have several uses besides measuring oxygen saturation. First, oximetry can serve as a replacement for blood gas analysis except in cases where acid-base state or PaCO2 is necessary. This method is also cheaper, easier to perform, and less painful compared to many others. It also has a higher level of accuracy especially in cases where the patient is conscious. Recorded values can be used to determine variations and to set standards in patients.
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 recording function in recording oximeters makes them to cost a little higher than other models. Prices vary according to the degree of complexity. Stores that sell medical equipment are among the places one can buy these devices from.
