Step 2: Specify Number and/or Type of Casualties

After you select a scenario on the Scenario Selection Screen, you must specify the number and/or type of casualties that you want to assume your hospital(s) will have to treat.

There are three buttons or links on this Web page:

• Select Previous to return to the Scenario Selection Screen.
• Select Run Model to have the Hospital Surge Model estimate the resources required to treat the casualties you have specified.
• Select Help to display the User Manual (note: you may need to disable your pop-up blocker to view the Help text).

For example, if you select the sarin scenario, the following Web page is displayed:

Scenario Selection Screen (for the sarin scenario)

For each of the scenarios, you have two options for specifying casualties:

• Specify the number and type of casualties. For example, you could specify that your hospital(s) receives 100 mild, 20 moderate, and 10 severe cases of sarin.
• Specify the number of casualties. For example, you could simply specify that your hospital(s) receives 130 cases of sarin. In this case, the casualties you receive are randomly selected from among all casualties from the attack.

The table below lists the type of casualties you can specify for each scenario:
