CHAPTER 1 INTRODUCTION 1.1 General MMED6000DP is a Portable Patient Monitor that has abundant monitoring functions and is used for the clinical monitoring of adult, pediatric and neonate. Besides, the user may select the different parameter configuration according to different requirements. MMED6000DP MMED6000 DP can be connected to the central working station to form a network monitoring system. MMED6000DP can monitor vital signals as ECG, RR, SpO2, PR, NIBP, TEMP, Dual-channel IBP (optional), CO2 (optional). It integrates parameter measuring modules, display and recorder in one device, featuring in compactness, lightweight and portability. Large true color  display provides clear view of 6 waveforms w aveforms and full monitoring paramete parameters. rs.

Fig.1-1 The display of MMED6000DP patient monitor is TFT LCD, which displays the patient

parameters, waveforms, historical data and monitor status. The screen is divided into five areas: (1) monitor status, (2) waveforms, (3) the table of  historical data, (4) parameters (5) menu as well as (6) frame of menu status.

Monitoring status frame Bed No.: indicates the bed number of the patient being monitored when the patient monitor is connected with the workstation. DEMO: indicates the device is in DEMO monitoring mode now. In clinical application, this function is not recommended because the DEMO will mislead the hospital workers to treat the waveform and parameter as actual data of the patient, which may result in delay of treatment or mistreatment. Start time: indicates the time powered on the monitor, it shows in “16:25”. Current time: indicates the current date and time, it shows in “05/16/2004, 10:10” Waveforms displaying area The waveform area can maximally display 6 waveforms. The colour of waveforms matches with the parameter’s on the right of the screen. For the maximum configuration, the waveforms provided by the system for selection are (from up to bottom): 2-lead ECG waveforms SpO2 waveform RESP waveform There are two means means to gain RESP RESP waveform, trans-thoracic impedance impedance and Et-CO2 (optional). If operator selects Et-CO2 (side stream) to monitor the patient’s respiration, respiration, the CO2 waveform will instead of the RESP waveform acquired by Trans-thoracic impedance. 2 IBP waveforms(option) waveforms(option) If operator selects IBP operation, the table of historical data will be instead of 2 IBP waveforms.

Numeric displaying displaying area The parameter area lies to the right side of the graphic g raphic area, which includes: includes:   ECG: heart rate (unit: beats/minute)   NIBP: from left to right, there are Systolic pressure, Mean pressure and Diastolic

     

     

pressure (unit: mmHg or kPa) IBP: the BP of channel 1 and 2. From left to right, there are Systolic pressure, Mean pressure and Diastolic pressure (unit: mmHg or kPa) SpO2: SpO2(unit: %) pulse rate (unit: beats/minute) RESP: respiration rate (unit: breaths/minute) TEMP: temperature of channel 1 and 2 (unit: Et CO2: unit: mmHg or kPa
