What are the Characteristics of Menntor X7 monitors?

A:  Menntor X7 is a modular, invasive, patient monitor with built-in 15″ display, with a Multi Parameter, plug in Module (MPM)

How does the MPM function when out of host?

MPM has an optional display of 5.8″ , with the display the MPM can be used during patient transfer, to monitor the patient and then merge the data from the transfer with data recorder on the host.

Does the Enguard remote monitor have full control on bedside monitors?

  1. In System Setup it is possible to set the Enguard to Read only mode, in which case the Enguard will enable only to view data from the bedside monitors and not modify the bedside display
  2. If in system setup the Enguard is set to Read/Write all monitor functions that do not require action as the bedside can be controlled and modified from the Enguard.
  3. The following functions can NOT be performed via the Enguard:
  • Invasive BP Zeroing
  • PCWP procedure
  • CVP from PAP
  • Cardiac Output Acquire
  • Timer
  • Freeze
  • NIBP Leakage test
  • EtCO2 Calibration

Can the Enguard view data of saved patients?

The Enguard has a “View Saved” mode, to view save patients data from any monitor on the network.

How many beds can be monitored at the Ensemble Central Station?

Does the Ensemble store patient data?

All patient data is stored at the bedside monitor, the Ensemble has full control, and view of the bedside monitors.

Do we need the Ensemble Central station to print patient data?

No, patient data is printed by the monitors via the LAN network, the Ensemble can command any monitor to send data to the printer.

Can the Ensemble control bedside function?

In System Setup it is possible to set the Ensemble to Read/Right or to Read only mode

What data will be lost, if the Ensemble central station looses power?

No data will be lost, since the patient data is stored in the bedside monitors and not in the central, that only provides access to the data stored at the bedside monitors

Does monitors provide analog output of vital signs waveforms?

Yes, Analog output is an option that has to be ordered with the monitor. The signal amplitudes are shown in the table below:

Signal

Amplitude

ECG II

1 Volt p-p / 1 mV

ECG V1

1 Volt p-p / 1 mV

ECG Sync

How is Cardiac output measured by Mennen Medical monitors?

CO can be calculated by Fick method or measured by Thermal Dilution measurement method

Could CO be measured in patient in Hypothermia or Hyperthermia?

The CO will work for body temperature  between 27 and 45  degree Celsius . Providing that injectate temperature is sufficiently low. In Hypothermic patient the injectate must be at zero temperature (Iced saline).

Could CO be measured in patient with unstable blood temperature?

To start a measurement we need to have a stable temperature with less then 0.07 degree change for at least 5 seconds.
To perform a measurement the core body temperature should be stable to better than 0.1 degree for the measurement period (10 – 20 seconds from injection).

Explanation : The measurement itself takes about 10 to 20 seconds during which the CO curve is built. The amplitude of the curve may be of about 0.5 degree. This means that to get a good measurement the core body temperature should be stable to better than 0.1 degree for that period.

Is CO compatible with all CO Swan–Ganz catheters?

YES ,What we need to know is the “Computation Constant”  that is provided by   the Swan-Ganz catheter manufacturer for each catheter and injectate volume and  temperature.

Are Mennen Medical monitor compatible with the various injectate methods?

Two different interface cables are available for CO.
One for COSET injection sets and one for YSI 400 temperature sensor.

Do the monitors have Continuous Cardiac Output (CCO) measurement?

No, the monitor do not provide CCO. The monitor could display CCO by interface with Vigilence, Vigileo or PiCCO.

In what forms Mennen Medical monitors store patient data?

Numeric data is stored numerically in Charts, and stored graphically in Trend.
ECG Waveforms are stored in Full Disclosure.

Vital signs are stored in the monitor at 1 minute resolution.
Chart: Data can be displayed as numeric Chart at selected time intervals (1 to 120 minutes).
Trend: Data can be displayed as graphic Trend with 30 minutes to 96 hours per panel.

How are waveforms stored in the patient monitor?

Full Disclosure:  ECG Full Disclosure waveforms are displayed on 10 minute panels of single channel, or  zoom in to10 second panels of 7 channels, or  4 second panels of 12 lead ECG.
Overview: Waveforms of all vital signs are displayed as 10 seconds panels

How are QRS marked in Full disclosure?

In “Zoom in” Full disclosure QRS are marked with RR interval in mSec as:
Dot: Normal, supra-ventricular QRS
V: Ventricular QRS

Beats with doubtful morphology where the algorithm does not come to conclusive definition
a  =  Abnormal QRS
b  =  Borderline QRS
c  =  Close to Normal QRS
B =  Bundle Branch Block (Regular, slow rate with Ventricular morphology)

Is patient data saved after patient discharge from the monitor?

Numeric Vital Signs and 20 second event strips of all waveforms can be saved after discharge. Check monitor specification for the data volume of Saved and Discharged patient data.

How are Event strips stored in the monitor?

How is Heart Rate (HR) calculated and displayed?

HR is averaged from a series of RR intervals and displayed every second the RR averaging formula is :
New Average = 3/4 old Average + 1/4  New value
HR = 60,000 / RR average [mSec]

Is 12 lead diagnostic ECC from chest leads same as 12 lead diagnostic ECC from limb leads?

No, Putting limb leads on the chest, may create a different vector directions compared to electrodes set on the limbs.

Does the patient monitor detect Arrhythmia?

Yes, the monitor uses the two top displayed ECG leads to detect arrhythmia.

Which leads are used to detect ST level?

ST level is measured on each of the ECG leads.

Could the ST measurement point be manually modified?

The default ST point is J+60 mSec. , it can be change manually.

Is it possible to compare the ECG shape at different time points?

ST  Watch panel enables to compare real time PQRST complex with up to three reference complexes.

Does the monitor detect Pacemaker beats?

Yes, pacemaker artifacts are marked by a red line.

Can ECG cables be sterilized?

Yes, sterilize with Ethylene Oxide gas. Do not use high temperature autoclave.

Does Microstream and MicroPod require calibration?

The only parameter that require calibration is Microstream or MicroPod that measure EtCO2.
The EtCO2 requires calibration after 1200 hours from first activation and then annually or after 4000 hours of use.
Use a gas canister of  5%CO2, 20% O2, Balanced with N2 for validation.

Is EtCO2 representing reliably the blood pCO2?

CO2 in alveolar air is balanced with pCO2 in the blood.
EtCO2, the end tidal CO2 is assumed to reach equilibrium  with the blood CO2 at high respiration rates the CO2 curve does not reach plateau and thus does not represent the alveolar air. Due to the high neonatal respiration rate, this situation is typical to neonatal EtCO2 measurement.

How is respiration measured?

Respiration is measured by chest impedance between LA-RA or RA-LL ECG electrodes.

What is the difference between Respiration Rate (RR) and Apnea?

RR is measured by number of Breath per minute, while apnea is measure by time without a breath

Can respiration be monitored in parallel with EtCO2?

No, when EtCO2 is monitored the RR is taken from the CO2 monitor and respiration from electrode impedance is disabled.
