Figure 8: Effect of Standard of Care on Evacuation Tim (Text Description)

This bar chart has a vertical axis labeled hours and a horizontal axis with three standards of care: Standard, 50% ALS->BLS, and ALS<->BLS. Each standard of care has three bars, one each for ALS, BLS, and Wheelchair. Standard is the baseline assumption (40 percent of patients require ALS ambulances and 20 % require BLS ambulances). The next category shows the time if half of the ALS patients were transported via BLS. The last shows the time if the proportions were reversed, i.e., if 40% of patients required BLS and only 20% required ALS transport.

ALS evacuation time 105.3 hours
BLS evacuation time 6.6 hours
Wheelchair evacuation time 5.4 hours

50% ALS->BLS
ALS evacuation time 33 hours
BLS evacuation time 17.6 hours
Wheelchair evacuation time 5.4 hours

ALS evacuation time 18.9 hours
BLS evacuation time 19.4 hours
Wheelchair evacuation time 5.4 hours
