Brief Summary:
In this study, the investigators will compare the accuracy of the Biostrap wristband, a wearable device with a clinical-grade Photoplethysmography (PPG) sensor, to measure ejection fraction and cardiac output in patients undergoing a cardiac ultrasound and pulmonary arterial catheterization, respectively.
Detailed Description:
This in an introductory clinical study with both cardiac patients undergoing elective cardiac ultrasound and cardiac ICU patients with pulmonary arterial catheters featuring Biostrap wristband. This is a single site, non-blinded, non-randomized study. The wristband is a wearable device that contains a clinical-grade Photoplethysmography (PPG) sensor which will measure parameters quasi-continuously and non-invasively. The device, Biostrap wristband, will measure cardiac ejection fraction (EF) and cardiac output (CO). We will enroll a total of 100 patients: 2 groups of 50. 50 patients undergoing an elective cardiac ultrasound as part of their routine medical care will wear the device for 1-2 hours as an outpatient depending on the duration of the test. 50 hospitalized patients with a scheduled or completed pulmonary arterial catheter inserted as part of their standard medical care will wear the device for 7 days.
The investigators will perform a retrospective analysis comparing the accuracy of EF and CO measured by the device in comparison to those from a 'reference device', which is the cardiac ultrasound for ejection fraction and the pulmonary arterial catheter for cardiac output values. Cardiac Ultrasound and pulmonary arterial catheters are standard of care procedures.
