Device Story

Model 2001 MARSpO2 Pulse Oximeter provides continuous, non-invasive monitoring of functional arterial oxygen saturation (SpO2) and pulse rate. Device uses ratiometric technique with red and infrared light sources; sensors (finger/toe) measure light absorbance through pulsating vascular bed. Dual microprocessor system: primary handles data acquisition, display, trending, and external communication; secondary (digital signal processor) performs filtering, pulse rate/saturation calculations, and noise reduction. Used in hospitals, EDs, ICUs, and during intra-hospital transport by trained operators. Output includes digital SpO2/pulse rate values and plethysmogram waveform. Audible/visual alarms for saturation/pulse rate limits and low battery. Serial port allows data output to printers/external devices. Benefits include reduced false/nuisance alarms via motion artifact filtering, improving monitoring reliability.

Clinical Evidence

Non-clinical bench testing and inter-device comparison studies conducted. Non-invasive controlled hypoxia studies performed to establish accuracy and ensure sensors meet published specifications. No clinical trial data on patient outcomes reported.

Technological Characteristics

Dual microprocessor architecture; digital signal processor for filtering/calculations. Red and infrared LED light sources; photodiode sensor. Measures SpO2 via ratiometric absorbance. Powered by AC or internal rechargeable lead-acid gel battery. Serial port connectivity. Software includes proprietary algorithms for signal processing and motion artifact reduction.

Indications for Use

Indicated for continuous, non-invasive monitoring of functional arterial oxygen saturation and pulse rate in neonatal, pediatric, and adult patients in hospital, hospital-type facilities, and intra-hospital transport environments (OR, ED, ICU). Use by trained operators when required by physician judgment.

Regulatory Classification

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.

#### d. Equivalent Devices

Substantial equivalence to the following legally marketed predicate devices with the same or similar indications for use has been demonstrated by a comparison of product features as described in the labeling and promotional literature for predicate devices and for the Model 2001, as well as testing to accepted industry standards. In addition, inter-device comparison studies and non-invasive controlled hypoxia studies were conducted to establish the Model 2001 accuracy and to ensure that the sensors meet their currently published accuracy specifications with the Model 2001. The predicate devices are as follows:

- Model 520A Pulse Oximeter, Novametrix Medical Systems, Inc., K913516 1.
- 2. Model 2000 Pulse Oximeter, Ivy Biomedical Systems, Inc., K982255
- N-395 Pulse Oximeter, Nellcor Puritan Bennett Inc., K991823 3.

#### Device Description e.

The Model 2001 Pulse Oximeter is designed for continuous, non-invasive monitoring of the functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate. Oxygen saturation is measured with ratiometric technique using red and infrared absorbance of oxy- and deoxyhemoqlobin and pulse rate is measured using the time between successive pulses. The O2 saturation sensors are already legally marketed as accessories to the Model 520A monitor. The Model 2001 displays digital values of SpO2 and pulse rate as well as a graphic display of the plethysmogram. The Model 2001 monitor consists of a dual microprocessor based data acquisition system that measures oxygen saturation data. The firmware for the primary microprocessor performs the functions of the existing Model 520A including data acquisition, display, trending and communications with external devices. The firmware for the second microprocessor, a digital signal processor, performs the filtering, pulse rate and saturation calculations of the existing algorithms and additional calculations which analyze the incoming signals and perform noise reduction on that signal when the presence of noise is detected.

{1}------------------------------------------------

The Model 2001 can be powered by either an internal power supply operating on AC or by a sealed rechargeable lead-acid gel battery. Audible and visual alarms for high/low saturation and pulse rate are available. The Model 2001 also includes a temporary (2 minute) and permanent alarm silence and other configurable settings. The Model 2001 provides an audible low battery warning to alert the user of impending loss of power and consequent loss of monitoring capability. The Model 2001 Pulse Oximeter has visual indicators for pulse error conditions, power mode (i.e. AC vs. battery) and alarm silence. There is also a serial port that provides user configurable data output capable of communicating with printers and other devices.

#### Intended Use f.

The Model 2001 Pulse Oximeter is intended to provide continuous, non-invasive monitoring of functional arterial oxygen saturation and pulse rate in neonatal, pediatric and adult patients in hospital, hospital-type facilities and intra-hospital transport environments such as the operating room, emergency department and intensive care The Model 2001 Pulse Oximeter and its sensors are intended to be used by units. trained operators when pulse oximetry monitoring is required in the judgement of a physician. The intended use, patient population and environments of use are the same or similar to the predicate devices, the Novametrix Model 520A Pulse Oximeter, Ivy Biomedical Model 2000 Oximeter, and the Nellcor Puritan Bennett N-395 Pulse Oximeter.

#### Technological Characteristics q.

The Model 2001 Pulse Oximeter measures functional oxygen saturation and pulse rate with sensors that contain red and infrared light sources. Since oxygen saturated blood absorbs different amounts of light at each wavelength (red and infrared) as compared with unsaturated blood, the amount of light absorbed at each wavelength by the blood in each pulse can be used to calculate oxygen saturation. The light energy from red and infrared LEDs is beamed through a sample cell- a pulsating vascular bed, the patient's finger or toe for example. The remaining light energy not absorbed by the sample cell reaches a photodiode, on the opposing side of the sensor. The signal received by the photodiode is split into its red and infrared components, sampled, software filtered, processed using proprietary algorithms and displayed as a numerical value for functional oxygen saturation and as a waveform, the plethysogram.

The Model 2001 uses a similar SpO2 and pulse rate software algorithm to process the information from the sensor as the predicate device, Model 520A Pulse Oximeter, cleared under K913516. In addition, the Model 2001 possesses artifact filtering software that reduces the effects of artifact such as patient/sensor motion. This allows the Model 2001 to provide valid SpO2 and pulse rate readings for increased levels of artifact as compared to previous generations. With this capability the Model 2001 provides a decrease in false/nuisance alarms due to the effect of motion artifact.
