## Device Name:

Trade Name: Atlas Monitor Common Name: Vital Signs Monitor Classification Name: Cardiac Monitor (including cardiotachometer and rate alarm)

## Predicate Device:

The predicate device for the Atlas Monitor is the Atlas Monitor cleared for market under 510(k) submission K984033, except for the improved SpO2 channel. The predicate device for the improved SpO2 channel in the Atlas Monitor is the Nellcor model N-395 pulse oximeter cleared for market under 510(k) submissions K991823 and K993637.

## Device Description:

The Atlas Monitor is a multi-parameter device used to monitor human physiological vital signs. It combines a CRT to display ECG and CO2 waveforms and LED's for other numeric values. There are (3) different models available.

The ECG front end will meet all applicable AAMI and harmonized EU standards (see safety reference section for particular standards). The Atlas Monitor will provide a 5 wire front end and will be compatible with both a 3 wire and 5 wire cable. Diagnostic (0.05Hz to 100Hz) and monitor (0.5Hz to 40Hz) bandwidth will be provided. The corresponding ECG waveform is displayed on the CRT. User can select which lead the monitor is displaying. If optional printer is installed that waveform can be printed.

The SpO2 value is obtained by the measurement of the red and infrared light absorbed by the patient's tissue. A probe, consisting of a detector and emitter, is placed on a patient at a point where profusion of a body part is close to the skin surface, like a hand digit. The changes in absorption are used to determine oxygen saturation and heart rate. The pulse signal graph LED bar indicates the relative strength of the pulses detected by the SpO2 module. The control board requires a single voltage input and generates all the necessary internal voltages. Communication to the Atlas Main board is via an internal serial communication interface. The SpO2 capability in Atlas is obtained by the utilization of OEM modules.

The OEM SpO2 modules are manufactured by:

| OEM P/N: MMONX75 | Nonin Medical, Inc. |
|------------------|-------------------------------|
| | 2605 Fernbrook Lane |
| | North Plymouth, MN 55447-4755 |
| OEM P/N: MP205 | Nellcor Puritan Bennett, Inc. |
| | 4280 Hacienda Drive |
| | Pleasanton, CA 94588-2719 |

The NIBP portion of the Atlas monitor utilizes the oscillometric method of blood pressure determination. In this method, the patient's arm is compressed and blood flow occluded through the use of a cuff and bladder combination. Each time the patient's heartbeats, a slight variation of pressure occurs in the cuff. The cuff pressure is decreased in a step fashion. The device measures and catalogs the pressure pulses at each step in cuff pressure. The patient's systolic and diastolic pressures are determined through the examination of these pulses.

The temperature portion of the Atlas monitor uses well established precision YSI 400 probes to monitor surface temperature of a patient. The YSI probes work on the principle of interchangeable thermistors (NTC Type) that exhibits a steep drop in resistance as temperature changes, providing high sensitivity to temperature changes. Welch Allyn, Inc. does not manufacture probes but it does recommend use of YSI 400 probes manufactured by:

YSI Inc 1700/1725 Brannum Lane PO Box 279 Yellow Springs, OH 45387

The impedance respiration feature utilizes the ECG lead set and patient surface ECG electrodes, together with additional electronics processing. The respiration rate in breaths/minute is displayed in numerical format on the CRT.

{2}------------------------------------------------

The end tidal CO2 (ETCO>) measurement is performed by utilizing an OEM PCB from:

Prvon Corporation N93 W14575 Whittaker Way Menomonee Falls, WI 53051

The Pryon side stream CO2 control board (LC101) is designed to acquire CO2 data utilizing an on board pump to aspirate a patient gas sample. Employing a proprietary side stream sensor, the C-cap bench. Patient waveform is obtained. The sensor is based on single beam single frequency and dual thermopile detector. The control board requires a single voltage input and generates all the necessary internal voltages. The control board outputs the CO2 waveform and performs all calculations for CO2 data and respiration rate, Communication to the Atlas main board is via an internal serial communication interface.

## Indications for Use:

The indications for use for the Atlas Monitor, model numbers 200, 210 and 220 include the monitoring of the following human physiological vital signs:

- Blood Oxygenation (SpO2) measurement .
- ECG waveform derived from 3 or 5 lead measurement .
- Respiration rate/waveform derived from ECG or CO2 .
- Temperature measurement via YSI 400 series probes .
- Non-Invasive Blood Pressure (NIBP) measurement .
- CO2 End-Tidal sidestream/waveform .
- Heart Rate derived from selected source (ECG, SpO2) .

The target populations are adult and pediatric populations. The monitor is intended for use within the healthcare facility setting.

## Technological Comparison to the Predicate Device:

The Atlas Monitor is the same as the Atlas Monitor cleared for market under 510(k) submission K984033. The improved SpO2 channel in the Atlas Monitor is a replacement for the SpO2 channel currently in the Atlas Monitor. Nellcor Puritan Bennett manufactures the SpO2 channel currently in the Atlas Monitor. The improved SpO2 channel is substantially equivalent to the SpO2 channel in the Nellcor model N-395 pulse oximeter. The Nellcor model N-395 was cleared for market under 510(k) submissions K991823 and K993637.
