Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to the reliability and feasibility of a novel optical heart rate monitor in hospital patients. Especially patients with atrial fibrillation are included. Patients will be monitored for two hours during routine post-operative care. The data from study device will be compared to routine monitoring. The design of the study is a Pilot feasibility study.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary use of photoplethysmography (PPG) measurement in clinical settings is usually the determination of the blood oxygen saturation level of the patient. The same device often reports also an average pulse rate of the subject.

If the subject has low blood perfusion in the hands or suffers from acute atrial fibrillation, the determination of the pulse rate is challenging and therefore the readings provided by current technology are unreliable.

Optical heart rate monitors (OHR) have recently become popular in sports and wellness applications and their performance in healthy subjects having normal blood perfusion in the extremities is well studied and documented and good accuracy has been shown healthy subjects. The performance of wrist-worn OHR monitors in hospital patients, however, has not been extensively studied.

The aim of the study is to test novel wrist-worn photoplethysmographic (PPG) device in surgery patients and study its feasibility in detecting heart rate and beat to beat heart rate of patients having normal sinus rhythm or arrhythmia, such as atrial fibrillation (AF).
