## Indications for Use
Nonin's Model X-100C CO-Met™ Oximetry System is indicated for noninvasive measuring of functional oxygen saturation of arterial hemoglobin (%SpO2), carboxyhemoglobin saturation (%COHb), methemoglobin saturation (%MetHb), and pulse rate of adult and pediatric patients (>66 lbs / 30 kg) using the Model 8300AA sensor. The measurements may be multiple spot-checks to observe change and/or continuous monitoring. The X-100C system is indicated for use by trained personnel in clinical settings, including Emergency Medical Service (EMS), hospitals, medical facilities, and mobile environments. This device is not meant for sole use in clinical decision making; it must be used in conjunction with additional methods of assessing clinical signs and symptoms.
## Device Story
Model X-100C CO-Met Oximetry System uses Model 8300AA reusable finger clip sensor to measure arterial hemoglobin saturation (%SpO2), carboxyhemoglobin (%COHb), methemoglobin (%MetHb), and pulse rate. Device processes signals from sensor; displays numeric values, pleth waveform, and alarm status on backlit LCD. Used by trained healthcare professionals in hospitals, EMS, and mobile environments. Provides real-time data and alarm management; supports AC or battery power. Output interfaces include Bluetooth, RS-232, and Nurse Call/Analog. Device intended for use alongside other clinical assessment methods to aid patient monitoring; does not provide diagnostic conclusions independently.
## Clinical Evidence
Clinical accuracy testing conducted on healthy adult subjects (18+ years) of varying skin tones. COHb and MetHb accuracy evaluated against co-oximetry (0-15% range). SpO2 accuracy evaluated during induced hypoxia (70-100% range) and in the presence of COHb/MetHb (80-100% SpO2, 0-15% COHb/MetHb). All testing performed per ISO 80601-2-61. Results demonstrated performance within acceptance criteria.
## Technological Characteristics
Noninvasive pulse oximetry using reusable finger clip sensor (Model 8300AA). Backlit LCD display. Powered by 7.2V Li-ion battery or 100-240 VAC. Connectivity: Bluetooth, RS-232, Nurse Call/Analog. Biocompatible materials (ISO 10993). IP32 ingress protection. Complies with IEC 60601-1, IEC 60601-1-2, and ISO 80601-2-61.
## Regulatory Identification
An oximeter is a device used to transmit radiation at a known wavelength(s) through blood and to measure the blood oxygen saturation based on the amount of reflected or scattered radiation. It may be used alone or in conjunction with a fiberoptic oximeter catheter.

COHb accuracy testing was conducted at an independent research laboratory on healthy, male and female, non-smoking, light to darkskinned subjects that were 18 years of age and older.
The measured carboxyhemoglobin value (%COHb) of the sensors was compared to simultaneous arterial blood samples as assessed by cooximetry. The accuracy of the sensors in comparison to the co-oximeter samples measured over the COHb range of 0-15% with 95 - 100% SaO2. Accuracy data was calculated using the root-mean-squared (Arms value) for all subjects, per ISO 80601-2-61, Medical Electrical Equipment- Particular requirements for basic safety and essential performance of pulse oximeter equipment.

#### MetHb Accuracy Testing
MetHb accuracy testing was conducted at an independent research laboratory on healthy, male and female, non-smoking, light to darkskinned subjects that were 18 years of age and older.
The measured methemoglobin value (%MetHb) of the sensors was compared to simultaneous arterial blood samples as assessed by cooximetry. The accuracy of the sensors in comparison to the co-oximeter samples measured over the MetHb range of 0 – 15% with 95 – 100% SaO2.
Accuracy data was calculated using the root-mean-squared (Arms value) for all subjects, per ISO 80601-2-61, Medical Electrical Equipment- Particular requirements for basic safety and essential performance of pulse oximeter equipment.
#### SpO2 Accuracy Testing
During no-motion conditions at an independent research laboratory, SpO2 accuracy testing was conducted during induced hypoxia studies on healthy, male and female, non-smoking, light- to dark-skinned subjects that were 18 years of age and older. The measured arterial hemoglobin saturation value (SpO2) of the sensors was compared to arterial hemoglobin oxygen (SaO2) value, determined from blood samples witha laboratory co-oximeter. The accuracy of the sensors in comparison tothe co-oximeter samples measured over the SpO2 range of 70 - 100%. Accuracy data was calculated using the root-mean-squared (Arms value) for all subjects, per ISO 80601-2-61, Medical Electrical Equipment— Particular requirements for basic safety and essential performance of pulse oximeter equipment.
#### SpO2 Accuracy Testing in Presence of COHb and MetHb
During no-motion conditions at an independent research laboratory, SpO2 accuracy testing in the presence of COHb and MetHb was conducted during induced hypoxia studies on healthy, male and female, non-smoking, light- to dark-skinned subjects that were 18 years of age and older.
The measured arterial hemoglobin saturation value (SpO2) of the sensors was compared to arterial hemoglobin oxygen (SaO2) value, determined from blood samples with a laboratory co-oximeter.
The accuracy of the sensors in comparison to the co-oximeter samples measured over the SpO2 range of 80 - 100%, range 0 - 15% COHb and SpO2 range of 80 – 100%, range 0 – 15% MetHb.
