詳細な説明
This is a prospective single-site data collection study designed to collect blood pressure (BP) waveforms and estimate BP via the CardiacSense (CS) BP Watch and CS BP Pillow Systems, in parallel with arterial line (A-line data), auscultatory BP cuff measurements and SpO2 measurements. The data collected will be used for algorithms development of the CS BP Systems.
The study includes a screening phase followed by BP data collection session. Participants will be recruited by the Investigator according to the study eligibility criteria. Each enrolled participant will be fitted with 2 CS BP Watches (one on each hand), a CS BP Pillow, A-line and a cuff for auscultatory BP measurement.
A minimum of 100 participants who meet eligibility criteria will be enrolled in the study. After informed consent is obtained, demographic information, medical history, current medication use, Monk Skin Tone Scale, wrist and bicep circumference measurements and baseline vital signs measurements will be recorded. A modified Allen's test, a lateral difference test using non-invasive cuff auscultatory readings and additional assessments will be performed to confirm eligibility criteria.
In participants who meet the eligibility criteria, study devices (CS BP Watch and CS BP Pillow systems) will be fitted, and an A-line will be inserted into the radial artery. A dynamic response calculation will be performed to confirm the integrity of the inserted line.
After the participant has rested for at least 5 minutes, simultaneous BP recordings using both Watches, the Pillow and the A-line will begin and continue for 1 hour. During the 1-hour recording, a few dual-observer auscultatory BP cuff measurements will be performed on the arm contralateral to the A-line arm by two trained observers.
Upon completion of data collection, all devices will be removed, and adverse events will be assessed and documented.
The end of study for each participant is defined as the completion of device removal and after AE follow up by the study team. The end of the trial is defined as the completion of at least 100 valid participant datasets.

実験的:CS BP Watch System and CS BP Pillow System
Data collected from the CS BP Watch and Pillow Systems will be compared to data collected from Arterial Line and auscultatory BP cuff measurements
|
The CS BP Watch System is a wrist-worn data acquisition system designed to estimate BP from time-synchronized ECG and PPG signals. The CS Pillow System estimates BP using a combination of ECG and tonometry signals. The system is comprised of a tonometry-based sensor which is embedded in a biocompatible "pillow" for improved sensitivity and comfort. The Pillow is placed over the pulsatile area of the radial artery using a wristband. Data collected using the CS Watch and CS Pillow Systems will be compared to data collected using Arterial Line and auscultatory BP cuff measurements
