Objective:
The aim of the study was to compare the Polar H10 and Bittium Faros™ heart rate variability monitors for use in occupational and environmental health research, considering data collection, storage, transfer, resource needs, and limitations.
Methods:
A literature review, device testing, and expert interviews were conducted to assess device performance and usability.
Results:
Polar H10 is affordable, records RR intervals for up to 20 hours offline, and requires a smartwatch and app for extended storage. Bittium Faros™ is a certified electrocardiogram monitor that records full waveforms, supports long measurements, and enables automatic data transfer. Both devices can be worn with a chest strap, but placement issues may affect data quality. Patch electrodes improve stability but may cause skin irritation.
Conclusions:
This assessment highlights key device differences to guide HRV monitor selection for occupational and environmental epidemiological studies.

01:30Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
