Multipara monitor -Application and Maintenance

A multiparameter monitor is a medical device for monitoring a patient's vital signs. It is mainly used in intensive care, hospitalization or Emergency Room.
It is also known as Vital Signs Monitor in its basic model. In general, basic models are used to monitor cardiac activity (ECG), blood pressure (NIBP), respiration (RESP), oxygen saturation (SpO2) and temperature (TEMP).

6. Patient Monitors Parameters

7. Other Critical Parameters in ICU The other parameters being monitored in the ICU are: Cardiac Output- It is the Volume of Blood pumped by Heart in one minute. It reflects the efficiency of Heart. Temperature EtCO2.- - End-tidal carbon dioxide is the level of carbon dioxide that is released at the end of an exhaled breath. ETCO 2  levels reflect the adequacy with which carbon dioxide (CO 2 ) is carried in the blood back to the lungs and exhaled. SpO2- Oxygen saturation  is a vital parameter to  define  blood oxygen content and oxygen delivery.  Invasive Blood Pressure.- Invasive  (intra-arterial)  blood pressure  (IBP)  monitoring  is a commonly used technique in the Intensive Care Unit (ICU) and is also often used in the operating theatre. This technique involves direct  measurement  of arterial pressure by inserting a cannula needle in a suitable artery.

8. Specific Physiological Monitoring

9. Components of Medical monitor Sensor and Transducers- Convert the physiological signals into electrical signals. Modules- Processes the electrical signals for displaying on Monitors. Display device- LCD/LED/TFT Displays Communication links-Interface to other devices like central monitoring. Alarm- Audio and visual alarms for critical parameters. Power Supply units- To power the various modules.

26. Performance Checking with a simulator You can check the performance of the Device with ProSim 8 from Fluke Biomedical. Watch the you tube link as below: https://www.youtube.com/watch?v=QUNtyaaWZ3Q

27. Troubleshooting Problem Possible causes and action to be taken 1. The unit is not powering ON. Check the Mains Power Supply. If the mains is OK then check the power cable. If it is OK then open the unit and check for the fuse in the power supply and replace with the same rating of Fuse in case of problem. If the fuses are OK check the voltages at various test points. If nothing works out replace the Power Supply board. 2. One of the parameters is not working. Check for the performance with a simulator and replace the module or the cable for that module. 3. The Machine is switching ON but the display will not switch ON. Check the fuses on the display board and replace if defective. Else replace the Display Unit. 4. Unit frequently trips. Check for the filters and clean the same. If not then do as in step number 1.

28. Preventive Maintenance Test to ensure the battery is charging correctly, and holding a charge. Note the charge  time, discharge time and voltage.    Ensure all alarms are functioning properly, including the Nurse Call Relay.    Check the cuff pressure (adult, pediatric or neonate) at the appropriate rate.    Check overpressure cut-off.    Run NIBP characterization test and verification.    Check SpO2.    Check for pressure leakage and accuracy.    Wipe down equipment, and check for any visible cracks or damage.
