Data Collection Study Using CS BP Pillow System
A Data Collection Study to Collect Blood Pressure Data Using the CardiacSense BP Pillow System for Algorithm Development
연구 개요
상세 설명
This is a prospective data collection single-site study designed to collect blood pressure (BP) waveforms and estimate BP via the CS BP Pillow System, in parallel with arterial line (A-line data). The data collected will be used for algorithm development of the CS BP system.
The study includes a screening phase followed by BP data collection session using the CS Pillow System and an A-line. Participants will be recruited by the Investigator according to the study eligibility criteria.
A total of 40 participants who meet eligibility criteria will be enrolled in the study in 2 cohorts: Cohort I and Cohort II. Each Cohort will include 20 participants. The cohorts will be identical with respect to study procedures and distribution of sex, body mass index (BMI), age, and blood pressure classification groups.
After informed consent is obtained, demographic information, medical history, current medications use and wrist circumference measurement will be recorded. A modified Allen's test, a lateral difference test and additional assessments will be performed to confirm eligibility criteria. In participants who meet the eligibility criteria, the CS BP Pillow will be placed over the radial artery and an A-line will be inserted into the radial artery of the contralateral hand. 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 the CS BP Pillow System and the A-line will begin and continue for about 1 hour.
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 completion of adverse event follow-up. The end of the study is defined as completion of 40 evaluable participant datasets

실험적: CS BP Pillow System
Data collected from the CS BP Pillow System will be compared to data collected from Arterial Line
|
Device: CS Pillow System - The 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 Pillow System will be compared to data collected using Arterial Line.
