“…A study by Kitsiripant et al [34] compared the Nellcor™ Bedside Respiratory Patient Monitoring System PM1000N to the Radical-7®, in terms of the devices' ability to detect apnea in volunteers. However, since the PM1000N's intended use does not include apnea detection, the purpose of the study is not clear.…”

Respiration rate (RR) is a critical vital sign that provides early detection of respiratory compromise. The acoustic technique of measuring continuous respiration rate (RR a ) interprets the large airway sound envelope to calculate respiratory rate while pulse oximetry-derived respiratory rate (RR oxi ) interprets modulations of the photoplethsymograph in response to hemodynamic changes during the respiratory cycle. The aim of this study was to compare the performance of these technologies to each other and to a capnography-based reference device. Subjects were asked to decrease their RR from 14 to 4 breaths per minute (BPM) and then increase RR from 14 to 24 BPM. The effects of physiological noise, ambient noise, and head movement and shallow breathing on device performance were also evaluated. The test devices were: (1) RR a , Radical-7 (Masimo Corporation), (2) RR oxi , Nellcor™ Bedside Respiratory Patient Monitoring System (Medtronic), and (3) reference device, Capnostream20p™ (Medtronic). All devices were configured with their default settings. Twenty-nine healthy adult subjects were included in the study. During abrupt changes in breathing, overall RR oxi was accurate for longer periods of time than RR a ; specifically, RR oxi was more accurate during low and normal RR, but not during high RR. RR oxi also displayed a value for significantly longer time periods than RR a when the subjects produced physiological sounds and moved their heads, but not during shallow breathing or ambient noise. RR oxi may be more accurate than RR a during development of bradypnea. Also, RR oxi may display a more reliable RR value during routine patient activities.
