The purpose of this study is to meet the respiration rate accuracy specifications for the study pulse oximeter monitoring system (study device) in a hospitalized volunteer population when compared to established technologies for measuring parameters related to respiration, such as Capnograph Respiration Rate (RR)(CO2).
Volunteer subjects from a hospital setting (see specific inclusion/exclusion criteria) over the age of 18, male and female, who provide written informed consent prior to the procedure, and are without any contact skin allergies to adhesives found in standard pulse oximetry sensors. A cross section of demographics - cardiovascular, respiratory, and metabolic type cases should be considered for a broad distribution of medical and surgical patients.
The study consists of measuring parameters related to respiration in hospitalized volunteers by means of the Bedside Respiratory Patient Monitoring System with RR V2.0 (Nightingale). The production-equivalent Nightingale device and multiparameter reference devices will be attached to the subject via sensors, nasal cannulas and ECG leads and the information from all devices will be captured continuously for up to 40 minutes to allow for at least 30 minutes of artifact free data 30 minutes.

| Mean Error (ME) +/- 1 Breath Per Minute, RR Sensor | The software calculates respiration rate values via Adult Respiratory Sensor with a mean error of +/- 1 breath per minute relative to a capnography based reference. The Mean Error value estimates the mean difference in simultaneous estimates of respiration rate (the Respiration Rate calculated from the sensor and the Respiration Rate calculated from capnography). | up to 40 minutes of continuous monitoring |

| Mean Error (ME) +/- 1 Breath Per Minute, Max-N Sensor | The software calculates respiration rate values via the Max-N Sensor with a mean error of +/- 1 breath per minute relative to a capnography based reference. The Mean Error value estimates the mean difference in simultaneous estimates of respiration rate (the Respiration Rate calculated from the sensor and the Respiration Rate calculated from capnography). The error value estimates the mean difference in simultaneous estimates of respiration rate (the Respiration Rate calculated from the Max-N sensor minus the Respiration Rate calculated from capnography. |
