Why the study?
Do pulse oximeters accurately estimate heart rate compared to ECG during rest and exercise in men?
Do pulse oximeters accurately estimate heart rate compared to ECG during rest and exercise in men?
Pulse oximeters significantly underestimate heart rates above 155 beats/min during strenuous exercise compared to ECG, questioning their reliability as heart rate monitors in this setting.
No takes yet. Share an insight, caveat, or question.
Pulse oximeters warrant caution for heart-rate monitoring above 155 bpm during exercise; leaves open prospective validation against ECG.
Iyriboz et al. (1991) studied this question.
