Clinical Trial Summary

The purpose of this clinical study is to validate the SpO2 accuracy of the Stryker Sustainability Solutions pulse oximetry sensors during motion conditions over the range of 70-100% SaO2 as compared to arterial blood samples assessed by CO-Oximetry. The end goal is to provide supporting documentation for the SpO2 accuracy validation of the reprocessed sensors.

Description:

In this study, the level of oxygen within the blood will be reduced in a controlled manner by reducing the concentration of oxygen the participant breathes. The accuracy of a noninvasive pulse oximeter sensor will be assessed by comparison to the oxygen saturation measurements from a laboratory blood gas analyzer.

It is required that the Accuracy Root Mean Square (ARMS) performance of the Stryker pulse oximetry sensors will meet a specification of +/-3% or better in motion conditions for the range of 70 - 100% SaO2 (typically, saturation is determined once with air breathing and then at one of 6 levels, e.g. 94%, 90%, 85%, 80%, 75% and 70% saturation for about 30-60 seconds at each level), thereby demonstrating an acceptable SpO2 accuracy performance specification. Motion is defined as controlled rubbing or tapping of the subject's fingers in a 2-4 Hz or random sine motion with 2-3 cm amplitude.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Accuracy of Sensor by Arms Calculation Under Motion Conditions	Percentage of SpO2 (oxygen saturation by pulse oximetry) measured by the Reprocessed Oximeter pulse oximetry sensors during motion conditions over the range of 70-100% SaO2 as compared to arterial blood samples assessed by CO-Oximetry. Accuracy root mean square (ARMS) between measured SpO2 and reference SaO2 (arterial oxygen saturation) must meet the 3% specification for each reprocessed pulse oximetry sensor style. Accuracy will be determined by comparing the noninvasive blood oxygen saturation measurement of the pulse oximeter to that obtained from a blood sample and calculating the arithmetic root mean square error (Arms) value. Standard deviation of the differences is computed as the precision. Square root of the sum of the squares of bias and precision is computed as the Arms Error value.	1-2 hours
