Official title
Evaluation of Sensifree's Alpha Sensor Signal Morphology in Comparison to Invasive Radial Arterial Line Pressure Waveform and PPG Signal Morphology
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of the protocol is to compare Sensifree Alpha sensor signal morphology, measured at the radial artery, to an invasive arterial line pressure signal and the oxygen saturation as read by a pulse oximeter. The study will be split into two phases: the first phase will collect data for morphology analysis and algorithm development, the second phase will compare device performance to the reference invasive blood pressures. A secondary objective is to evaluate signal morphology changes due to changes in subject arm position.
