Wrist Pulse Oximeter
With cardiac arrests and asthma attacks getting common every day, the need to measure the pulse rate and oxygen saturation instantly on the move is also increasing. This has led to the evolution of wrist pulse oximeters which are highly portable and easy to handle that they have found common use among individuals. Wrist pulse oximeters are very simple to use - they only require that the sensor be fit to the fingertip and the display be worn around the wrist. The sensor measures the level of pulse rate of the individual by sensing through the fingertips. It further measures the level of oxygen saturation through the percentage of oxygen present in the hemoglobin of the blood. The results are thereby displayed on the screen that is around the wrist of the individual. The wrist pulse oximeter proves to be highly attractive compared to the other models like table top oximeters or hand held oximeters due to various features.
First of all, the wrist pulse oximeters are portable and very simple to use and handle. They just require two actions – wearing the display around the wrist and fitting the sensor to the fingertip. Unlike the portable pulse oximeter or table top oximeters, wrist pulse oximeters do not have the difficulty of carrying long cables in the hand which would at times get tangled. This is especially useful for measuring the pulse rate and oxygen saturation level I children who would at times turn messy and refuse to cooperate to take the readings.
Second, the wrist pulse oximeters are provided with the features to record continuous measurements of pulse rate and oxygen concentration in the individual. The data measured from the individual is saved and recorded into the device. Wrist pulse oximeters have the ability to store data ranging from 80 hours to 270 hours of measurements of pulse rate and oxygen saturation. In order to avail this facility, the software to record the data should be downloaded and the records of measurements could be viewed on the desktop screen of PCs or laptops. Some wrist pulse oximeters also have the features to connect through Bluetooth devices so that the recorded measurements could be viewed on mobile phones or other devices with Bluetooth connectivity.
Third, wrist pulse oximeters can be used for measuring the pulse rate and oxygen saturation levels for longer periods continuously. The sensor of the oximeter is designed in such a way that it would not cause fatigue when it is kept for longer duration on the fingertips. In addition, the battery of wrist pulse oximeters are also designed to record measurements for longer time periods without getting switched off. This enables continuous monitoring of individuals especially when they suffer from cardiac problems or asthma attacks. Finally, wrist pulse oximeters are designed to suit the needs of adults and children with specific calibrations related to their anatomic needs. The sensor is designed based on the finger size of adults and children and are therefore available in two different models.
