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 emits infrared and red lights from two light emitting diodes comprised in the sensor. When in use, the detectors and diodes should be opposite to each other. A tissue of about 5-10 mm should separate the detector from the diode. For this reason, the sensor of the oximeter must be attached onto thin tissues. Sensors are normally made to look like wraps or clips. According to recent findings, oxygen saturation is not effectively measured through earlobes.
These devices are very useful in any setting where the amount of oxygen saturation within the body needs to be known at all times. Such settings include emergency units, intensive care, operation rooms, and in recovery and treatment wards in hospitals. Patients are advised to keep calm or minimize major movements in order to ensure accuracy of the readings. Devices with recording capability are better because they maintain a history of all values taken over a given period.
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 ensure economical use of oxygen supplied to patients in tanks hence avoiding wastage. Additional uses are in intrapartum fetal monitoring and neonatal care. However, use in intrapartum fetal monitoring and neonatal care are not fully developed and standardized but they will soon. Modern ambulances are equipped with these devices for first aid to patients. GP kits are also becoming 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.
