Clinical Studies
Two (2) prospective, observational, non-randomized clinical studies were conduct-
ed to demonstrate the accuracy of Respiration Rate Version 2.0 when used in con-
junction with the Nellcor™ Bedside Respiratory Patient Monitoring System, using
the Nellcor™ Adult Respiratory Sensor. One study was performed with healthy
recruited volunteers at a single clinical laboratory. A second study enrolled volun-
teer subjects from a hospital population. Accuracy was established by comparison
to respiration rate determined from capnography waveforms.
1.11.1
Methods
Data from 105 enrolled subjects were included in the analysis: 30 healthy vol-
unteers and 75 hospitalized patients. Subjects were studied for approximately
30 minutes during which data from capnography and the Nellcor pulse oxim-
eter were collected. Respiration rate was derived every five seconds using Res-
piration Rate Version 2.0. The reference was obtained from counting breaths
on the capnography waveforms by an anesthesiologist blinded to all other
data.
