ProSim 8 Vital Signs and ECG Patient Simulator

You can execute factory autosequences in 2 ways
a) 1st way: Open a factory template from the Ansur template library. Click play button from Ansur toolbar and click Start button from the testguide
b) 2nd way: Open Ansur Mini Plug-In. Click Autosequence tab. Select any autosequence from the list. Click Play button. Click start button from the testguide

To create autosequence similar to the autosequence present in the ProSim
simulator follow the steps below
a) Drag and drop Autosequence container to the template
b) Drag and drop one more autosequence container under it. This becomes the step which simulates the test elements in parallel
c) Drag and drop test elements under the step
d) Save it as custom templates in the Ansur test library or to any other location in PC

a) The total duration of the execution of the step is the sum of the duration set in each test elements under the step
b) If any one of the duration is set as indefinite then the step execution will be continuous until Next button or Stop button is clicked.

a) If you want to execute tests sequentially one by one and enter the results individually and navigate to next test element manually then, drag and drop the test elements into the template without autosequence container
b) If you want to execute tests sequentially one by one and enter the results individually and navigate to next test element automatically then, drag and drop the test elements into the template under the autosequence container
c) If you want to execute tests in parallel at the same time and enter the results after each step then, drag and drop the appropriate test elements under the step

1. Made clear mention of it in the user manuals.
2. Added a colored flag to the battery charger (ProSim 4 = yellow label, ProSim 8 = red label).
3. Designed electrical protection from possible burn-out from application of the wrong battery charger. Please keep in mind: though this protection is in place, using the wrong battery charger can cause loss of some battery life if connected to the wrong voltage for extended periods of time.

The ProSim power circuits were designed to operate over a specific range of battery voltage levels. As the battery charge is depleted, the battery voltage drops. At a point just above the minimum design voltage for the power supplies, the ProSim will shut itself off. The firmware monitors the battery charge level and warns the customer in advance of this shutdown so that they can respond appropriately (e.g., save date, plug in the charger, swap out the battery pack, etc.).

As long as there is sufficient battery voltage for the ProSim to remain powered on, all circuits will operate normally, even at 0 % charge level. This is because the ProSim doesn't run directly on the battery voltage, because the battery voltage varies and precision circuits need a stable power supply voltage to work properly. The ProSim first converts the variable battery voltage into a stable voltage that doesn't change even when the battery charge level is very low.

Improper cuff size has been considered one of the most common errors with blood pressure measurements. It is well documented that readings can be falsely elevated, sometimes to the extreme with a cuff that is too small. The rule established by the American Heart Association (AHA) suggests cuff width should be at least 40 % of the greatest arm circumference.

Doctors have determined a normal range for both systolic and diastolic blood pressure after examining the blood pressure of many people. The following figures can be used as a guide for adult blood pressure:
1. Normal blood pressure: less than 120/80 mmHg
2. High/Normal: between 120/80 and 140/90 mmHg
3. High: equal to or more than 140/90 mmHg
4. Very high: equal to or more than 180/110
Individuals whose blood pressure is consistently higher than this norm are said to have high blood pressure, or hypertension. Uncontrolled high blood pressure is indirectly responsible for many deaths and disability resulting from heart attack, stroke, and kidney failure.

The design of the NIBP parameter of a patient monitor is required to be proven to be safe and effective for use in the diagnosis, and treatment of disease states and underlying chronic conditions, and in the prescribing of medications and other therapies. This testing is governed by national and international standards including AAMI/ANSI SP10 and IEC 80601-1-2-30 for minimum performance and safety. The performance of NIBP monitors are required to be evaluated or tested during scheduled maintenance by the manufacturer.

Each individual manufacturer utilizes their proprietary algorithm for identification of the systolic and diastolic points. Some may use the height of the pressure waveform to mark these points; others may use the slope of the pressure signal. Given that algorithms vary, it is difficult to compare between different blood pressure monitors from different manufacturers.

The auscultatory technique is based on the sounds caused by the blood flow through the artery that is surrounded by the cuff. These sounds are known as Korotkoff (K) sounds. In manual blood pressure measurement, these sounds are detected by a human observer using a stethoscope.

The oscillometric technique does not use K sounds to determine blood pressure. The oscillometric technique monitors the changes/vibrations in cuff pressure caused by the flow of blood through the artery. The monitor inflates the cuff to a pressure that occludes the artery.

Variability between auscultatory and oscillometric blood pressure readings may be due to many factors including human observer's skill and hearing sensitivity. The main reason an oscillometric reading is typically higher is that the human ear can only pick up sound, not vibrations. Vibrations in the artery occur before any sounds have appeared, so by the time the human ear hears the Korotkoff sounds, systolic may have already occurred.

• Connect ProSim 8 and HP Viridia monitor with proper IBP cables
• Select IBP on ProSim 8, ZERO both IBP channels
• On HP/Viridia, select MODULE SETUP
• Then select PRESS 1 ABP
• Press ZERO XDUCER
• ZERO IN PROCESS should display on the monitor
• Initiate the ProSim 8 IBP simulation. IBP numbers should display on the HP Viridia monitor

ProSim 4 simulates following 4 parameters:
1) ECG (including normal and Arrhythmias)
2) Respiration
3) IBP (Invasive Blood Pressures)
4) NIBP (Non-Invasive Blood Pressure)
