      comparison study.

AB  - 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.
