Buyer's Guide: Oximeter Tester

What Is the Significance of Pulse Oximeter Testing?

The purpose of the present study was to assess the reliability of the oxidizer-based and non-oximeter pulse oximeter sensor. The test was done on nine patients with heart disease who were being treated at the time for chronic myocardial infarction, a life-threatening condition. During the clinical trial, the oximeters measured the percentage of saturated and nonsaturated arterial oxygen saturation. The patient's medical history, clinical presentation, blood flow measurements and previous treatments were also analyzed.

There are different types of oximeter pulse oximeters. One of them is the infrared-based probe and the second one is the optical based probe. The infrared-based probe has more accurate results but has shorter range. Optical based probe has higher reliability rate but has shorter range as well. Therefore, the purpose of the present study was to assess the reliability of both types of pulse oximeters.

The study was done using a handheld infrared-based pulse oximeter tester. The procedure of testing was done by using standard surgical procedures and hospital equipment. The procedure of testing involved placing the infrared-based probe into the patient's fingertip area. The patient was required to cover his eyes with a plastic bag. An infrared light passing through the skin of the finger was detected by the handheld pulse oximeter tester, which resulted in obtaining detailed information about the patient's blood oxygenation status.

In the process of clinical trial, it is expected that the accuracy rate of the oximeter pulse oximeter tester will be greater than ninety percent. However, this rate depends on the type of sensor used. It should be noted that some manufacturers use external electrical resistors instead of electronic transducers. These external resistors have lower power requirements and are therefore easier to use, which in turn result in an increase in their usability.

The second part of the clinical trials assessed the reliability of the pulse oximeter sensor. The studies also showed that both types of sensors had good response when determining the percentage of saturation. However, there were differences in both the percentages of saturation. The percentage of saturation that the oximeter sensor can detect changes depends on the length of the pulse and the sensitivity of the sensor. The higher the sensitivity of the sensor, the better it would be in detecting percentage of saturation changes.

Sensitivity of the sensor also differs from one type of sensor to another. For example, the majority of pulse oximeters available in the market today have higher sensitivity level than the one from the previous generation. This is because the earlier generation sensor has a shorter reaction time when determining the percentage of light emitting diode (LED) or infrared light entering the patient's blood stream. On the other hand, the latest generation of oximeters is able to measure light emitting diode (LED) and infrared light entering the patient's blood stream with higher sensitivity.

The process of obtaining reliable results and evaluating the accuracy of the device are two important factors for the success of pulse oximeter application. The percentage of light that enters the blood stream plays a major role in this process. Therefore, it is significant to evaluate whether the LED light emission is higher or lower than the percentage of light entering the arterial oxygen saturation. This is also evaluated through a Spo2 measurement, which is considered to be the most reliable method in determining percentage of light entering the arterial oxygen saturation.

The importance of testing procedures and the standard flex features of the oximeter are further highlighted in studies. Studies reveal that these two factors have a significant impact on the results of the pulse oximeter test. While the test procedures may be influenced by environmental conditions such as room temperature, individuals with certain health problems are more sensitive to environmental factors such as elevated temperatures. The importance of standard flex features, which allow the use of different body parts in pulse oximeter tests, is also highlighted in this study. Studies reveal that individuals with neurological disorders, diabetics, and patients undergoing laboratory tests are most sensitive to changes in temperature.
