Masimo oximeter's greater PTT variability cautions against interchangeable use for timing metrics; leaves open optimal device selection for photoplethysmographic cardiovascular monitoring.
Does the Masimo SET Rad-9 pulse oximeter improve photoplethysmographic signal phase characteristics compared to the Novametrix Oxypleth in healthy adults?
Raw photoplethysmography signals obtained from different modern pulse oximeters exhibit significant variability in phase delay, which can substantially affect the accuracy of timing-related cardiovascular measurements like pulse transit time.
