Philips M3/M4 Portable Monitor - Refurbished

(800) 462-8195


Patient demographics, measurement data and trends, acquired and stored in the MMS, can be transferred to the M-Series (M3/M4)3 and Philips IntelliVue (MP60/MP70/MP90) patient monitors.

EASI™-derived 12-lead ECG4 using a 5-electrode cable set.

Multi-lead Arrhythmia.

Up to 3 channels of ECG with basic Arrhythmia and ST Analysis capability.

FAST-SpO2 measurement, using Fourier Artifact Suppression Technology, for accurate performance even with low perfusion.

Respiration, Non-invasive and Invasive Blood Pressure, and Temperature measurements.

Mainstream or Sidestream CO2, a second Invasive Blood Pressure and Temperature measurements, and enhanced Arrhythmia capability, available optionally.

The M3/M4 Compact Portable Patient Monitor (M3046A) is a small, light patient monitor offering a flexible monitoring solution to suit a broad spectrum of monitoring needs. The monitor works together with the M3001A Multi-Measurement Server (MMS) and the M3012A/M3015A/M3016A Measurement Server Extensions to give you standard-of-care measurements.


  • Choice of serial interface for a dedicated external strip chart recorder (as default), or IrDA interface for connecting to a local printer.
  • 3-wave or 4-wave displays are available.
  • Trend data, with manual and automatic event storage, together with a range of report styles help you track and document your patient's progress.
  • Color display with a wide viewing angle.
  • Optional battery informs you of remaining capacity, and allows longer transport times. It can be easily exchanged during transport with no loss of settings.
  • TouchBar human interface — quick to learn and easy to use.
  • Rubber bezel protector, available in four colors, gives additional protection in transport scenarios.

Patient Transfers Patient demographics, measurement data and trends (for up to the last eight hours at one minute resolution for all numerics), are stored in the MMS, and can be uploaded to other Philips patient monitors - up to the last four hours to the M-Series (M3/M4)5, and the full eight hours to the IntelliVue family. Patients can be transferred by disconnecting the MMS from the monitor, and then reconnecting it at a new monitor.

Local Recorder

You can connect a dedicated, standalone strip chart recorder (GSI Lumonics XE-50p, order number M3080A #H20) to your monitor via the optional serial recorder interface (see Ordering Information).

The following recordings are supported:

  • Real-time local strips
  • Delayed local strips
  • Alarms
  • Vital signs
  • Trends and stored events


The color display has a wide viewing angle, and excellent visibility from a distance, so you can easily recognize and see the data you need for decision making. For applications where a larger display is required, an additional display can be connected to the monitor via the standard VGA output (consult your Philips representative for further information).

Networked Systems

In larger installations, several of these monitors can be networked and connected to a Philips

Information Center — with or without wires, for ultimate flexibility. Such a networked system not only allows central monitoring, but also bed-to-bed overview on any connected monitor. A permanent indication at the top of the screen conveniently shows the alarm status for beds assigned to the caregiver's group at all times.

Intended Use

The M3 and M4 patient monitors are designed for use by clinicians for adult, pediatric and neonatal patients in Critical and Intermediate Care areas, in Operating Rooms and General Wards, and for transport inside and outside the hospital. U.S. Federal Law restricts this device to sale by or on the order of a physician.
