Summary
Thirty VATS patients were monitored with a camera-based photoplethysmography system (FaCare) across four anesthesia stages and compared against a GE CARESCAPE B850. Agreement was strong: 88.1% of heart-rate correlation coefficients >0.8 and tight Bland–Altman limits for heartbeat intervals. Performance held under OR lighting, suggesting a viable noncontact option.
Practical implications
• Useful as a noncontact adjunct when infection control or patient comfort matter.
• Works under typical OR conditions, but algorithms, sync, and sampling need refinement before routine adoption.
• Consider parallel use with standard monitors during implementation to validate in your setting.
