Polar rs800cx bike

Indicators related to the blood circulation system include HR, BLa-, PI, and SaO₂. The HR was continuously monitored by Polar RS800CX BIKE. After entering the laboratory, subjects wore Polar RS800CX BIKE, and the HR was recorded at the required time. Lactate Plus™ BLa- analyzer, Nova Biomedical, USA, was used for BLa- testing. A calibration test is performed before the test, BLa- is tested at the required time points, and the results are recorded. PI and SaO₂ were monitored continuously using Masimo Radical-7. The tester was clamped on the nondominant ring finger of the subject, and the PI and SaO₂ were recorded at the required time point.
