WebbMedian (range) RR from RIP and pleth were not significantly different at 42 (25-65) and 42 (25-64) breaths/minute. Median (range) % of epochs rejected due to artefact was 20 (8-75) for pleth and 10 (3-53) for RIP. Our results suggest that home respiratory rate monitoring by pulse oximeter pleth signal is accurate and feasible.

WebbTo investigate whether valid respiratory data can be extracted from the pulse oximeter plethysmographic (pleth) trace in healthy newborn infants, pleth data were collected from the foot, and respiratory airflow was simultaneously measured using a facemask. WebbOf note, in the face of a low signal (or low perfusion) some oximeters may auto adjust the scale of the display (y axis) to increase the visual amplitude of the pleth. This can be misleading to clinicians who must also pay attention to signal quality indicators when available. References: Jubran, Crit Care 2015 Keywords: pleth, waveform, PPG
