Standard Functions of VITALMAX 4100

EKG / ECG – Choose a 3 or 5 lead cable.

Blood Pressure measurement (systolic, diastolic, and mean arterial pressures) can be set to three different modes:

  • Manual – Press button to take one immediate blood pressure.
  • Automatic Mode – Set up time interval for automatic readings from 1 to 480 minutes. Caregivers typically set the interval to 10 minutes before surgery, 5 minutes post surgery.
  • Stat Mode – The monitor takes continuous readings, one begins as soon as the previous ends.

Hook up the included finger probe for SpO2 readings and heart rate. Set patient specific high and low levels to alarm immediately when a patient goes out of range.

Two skin surface temperature readings are available with YSI 400 series skin probes (standard in the industry). One reusable probe comes with every unit, disposable probes are available at any medical supply company.


The second skin temperature (taken with an esophageal or rectal probe) reading can be used during invasive pressure when delta temperature (the difference between the skin temperature and the core temperature) is necessary

Thoracic Impedance respiration measure the rate of breathing as taken through ECG leads on the patient’s chest, instead of using nasal cannula in the nose

Cardiac Arrhythmia are abnormalities in a patient’s heartbeat, the VITALMAX 4000 measures 13 different types. The graphical analysis in the monitor detects the arrhythmia, indicates its type, and shows the PVC counts (the frequency of the arrhythmia during that time). It can be turned on and off. St Segment Analysis measures the amplitude of the spike during each arrhythmia.

Optional Functions of VITALMAX 4100

There are two ways of measuring blood pressure: Direct (Invasive Pressure or IP) and Indirect (Non-invasive Blood Pressure or NIBP) method. The indirect method uses simple equipment but provides limited physiological information. The direct or invasive method (IP) provides accurate pressure measurements in regions of the cardiovascular system that are inaccessible to the indirect method.


To measure blood pressure by the invasive method, a catheter is inserted in a blood vessel and taken to the point of interest. The catheter has a transducer that provides electrical signals, which are then processed and analyzed by the monitor. Measurements of blood pressure by the invasive method give the systolic (maximum), diastolic (minimum) and mean pressures.


The invasive pressure range is from -30 to 300 mmHg, allowing the operator to use the monitor for measuring arterial pressure, pulmonary artery pressure and central venous pressure.


ΔTemperature comes with the invasive pressure module.

Both wave forms and numerical tabular data continuous real-time printing at the monitor.

The Anesthetic Agent Module (AAM) incorporates the latest design techniques and solid-state technology to redefine compactness and reliability. Miniaturization and performance advancements lead to an extremely cost-effective measuring of all five relevant anesthetic agents, as well as carbon dioxide and nitrous oxide. Ingenious solid-state design means that there are no moving parts to wear out.


The result is a solution that is highly shock-proof, while featuring low power consumption and an exceptional degree of integration flexibility into the finished product.


The infrared technology consists of a multi-spectral detector that operates according to the principles of absorption measuring and ray mixture. During each use, the infrared light is reflected in four directions after which it passes through a filter. The filters are laid out so that they are only permeable for a small wave length bandwidth in which the analyzed gas shows a particular absorption characteristic. Consequently, it is possible to determine the concentration of the gas, based on the light intensity measured by a sensor. And unlike other sensors, the AAM is not susceptible to cross-sensitivities due to gases like water vapor, ethanol or acetone.


A rapid response time of less than 350ms for CO2 and less than 500 ms for other gases enables the AAM to differentiate between inhaled and exhaled gas concentrations. Plus, the functional range of the AAM provides automatic identification of the agent, including identifying and quantifying a mixture of two different anesthetic gases. Yet both sensors are lifetime calibrated and require only minimal maintenance.

The external module for End-tidal CO2 monitors the patient’s continuous carbon dioxide levels before a breath compared to the levels after. States are increasingly mandating that during any procedure including sedation, conscious sedation, caregivers must monitor end-tidal CO2.


All VITALMAX monitors have an end-tidal CO2 port connector standard on the front panel. Either include the module with your purchase or easily upgrade at a later date.


The VITALMAX uses a reusable Nafion tube line that absorbs moisture in the patient’s breath (dehumidification), eliminating the need for a water trap and risks of cross contamination.

Delta Temperature automatically included when invasive pressure is added to unit.

Standard Features of VITALMAX 4100

The large 15″ TFT LCD, high definition touch screen is fully configurable to the needs of your care setting. View a large screenshot and learn more about this amazing monitor interface. View examples and read more about the VITALMAX touch screen display.

Audio and visual alarms for all parameters. Alarms are fully programmable for each patient.

  • Alarm Events – caregivers can check the unit at any time to recall alarm events that transpired during the patient’s monitoring. It detects the event parameter and measurement that caused the alarm.
  • Alarm Triggered Printing – automatically prints a paper trail of any alarmed events.

This is a measurement from the ECG and SpO2 that combines heart rate, respiration rate, oxygen levels, and oxygen levels to indicate breathing efficiency.

All Monitor manufacturers send out data in a standard format over the Ethernet/RS-232 , the electronic health record software determines how to manipulate the data within its system.

All monitoring information can be displayed in either numerical or waveform graphical form. Graphical display can be frozen or recalled to any point in the current monitoring session

The VITALMAX 4000 is adaptable for use in settings involving all types of patients

The lead acid battery recharges when the unit is plugged into an outlet

All parameters can be displayed in real time graphical wave forms. Configure up to 8 channels in any order or color. Large fonts are also available for viewing from across the room. Users can freeze the waveform at any time by touching it on the screen or recall any point within the current session

Automatic switch-over to battery operation occurs upon removal of AC power. While operating from AC power, the battery is automatically recharged

Recalled patient history data in graphical or tabular format can be displayed on the screen or transferred to on the computer for analysis via RS232 interface and printed, if a recorder is installed.


The recall patient history data for all parameters is the average of a 6-second sample of the data. Ninety-six (96) hours of recalled data is stored in a nonvolatile memory. The memory can save the data, alarm events, and the latest waveforms for each patient in the recall patient history
