The purpose of this study is to study Non-Invasive Performance evaluation of monitoring algorithm.

Focus of the Study is Measuring Respiratory Rate

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Novel Cardio-Respiratory Parameter in Healthy Volunteers

Further study details as provided by Covidien:

Primary Outcome Measures:
  • The Covidien Nellcor Respiration Rate Software Shall Determine Respiration Rate Measured as Mean and Standard Deviation With Accuracy That is Non-inferior to Predicate Device. [ Time Frame: Participants were monitorerd on average of 30 minute period ] [ Designated as safety issue: No ]
    Mean and standard deviations of respiration rates collected from healthy volunteers were compared between Covidien Respiration Rate Software, Transthoracic Impedance and Overscored End-Tidal Carbon Dioxide Waveforms. Each volunteer served as its own control.

Secondary Outcome Measures:
  • The Covidien Nellcor Respiration Rate Software Shall Calculate Respiration Rate With a Root Mean Square Difference (RMSD) of < 3 Breaths Per Minute Compared With a End-Tidal Carbon Dioxide Waveforms, With 95% Confidence. [ Time Frame: Participants were monitored on average of 30 minute periods ] [ Designated as safety issue: No ]

    The data used for analysis consisted of multiple simultaneous measures of RR_TTI, RR_V1.0 and RR_EtCO2 for each subject. Given N sets of simultaneous RR values for each of P patients, the simultaneous RR values were used to calculate a pair of RMSD values for each subject.

    The two RMSD values, RMSDRR_V1.0_vs_EtCO2, and RMSDTTI_vs_EtCO2, quantify the mean absolute difference in simultaneous estimates of respiratory rate between RR_V1.0 compared with RR_EtCO2 and RR_TTI compared with RR_EtCO2, respectively for the subjects with 95% confidence of mean ± 3.38 BrPM. The Measure type is Number and represents the RMSD of Covidien Nellcor Respiration Rate Software
