No
The document describes standard physiological monitoring techniques (SpO2, ECG, NIBP, Temperature, Respiration, CO2) and does not mention any AI or ML algorithms for data processing, analysis, or interpretation. The device description focuses on hardware components and established measurement principles.
No
The device is a multi-parameter monitor for human physiological vital signs. It measures and displays various physiological data (e.g., SpO2, ECG, NIBP, temperature, CO2, heart rate, respiration rate) but does not actively provide therapy or treatment. Its function is limited to monitoring for diagnostic or observational purposes.
Yes
The device is intended to monitor physiological vital signs such as blood oxygenation, ECG, respiration rate, temperature, non-invasive blood pressure, CO2 End-Tidal, and heart rate, which are measurements used to assess a patient's health status and potentially aid in diagnosis. Additionally, the ECG feature provides "Diagnostic (0.05Hz to 100Hz) and monitor (0.5Hz to 40Hz) bandwidth", explicitly stating a diagnostic capability for ECG.
No
The device description clearly outlines multiple hardware components including a CRT display, LEDs, probes, cuffs, bladders, and OEM modules for SpO2 and CO2 measurement. It is a multi-parameter hardware device with integrated software.
Based on the provided information, the Atlas Monitor is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Atlas Monitor's Function: The Atlas Monitor directly measures physiological vital signs from the patient's body using non-invasive methods (SpO2, NIBP, Temperature, ECG, Respiration, ETCO2). It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states the monitoring of human physiological vital signs, not the analysis of in vitro specimens.
Therefore, the Atlas Monitor falls under the category of a patient monitoring device, not an IVD.

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.
| FEATURES | MODEL 200 | MODEL 210 | MODEL 220 |
|---|---|---|---|
| ECG | Yes | Yes | Yes |
| SpO2 Nellcor MP506 | Yes | Yes | No |
| SpO2 Nonin | No | No | Yes |
| NIBP | Yes | Yes | Yes |
| Temperature | No | Yes | Yes |
| Impedance Respiration | No | Yes | Only if ETCO₂ is not running |
| ETCO₂ | No | No | Yes |
| Printer | Option | Option | Standard |
| Battery Backup | Not Available | Standard | Standard |
| RS423 I/O | Not Available | Standard | Standard |
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 | |

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.
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.
