Table 2.

Sensitivity analyses results showing the best case, estimated case, and worst case costs and the proportion of costs compared to Option One (status quo)

	Best case		Estimated case		Worst case
	Cost	a	Cost	a	Cost	a
Option One – cylinders only	–	–	$793,034	0.0	–	–
Variables
Cylinders	$327,940	0.41	$434,032	0.55	$552,587	0.70
Concentrators	$412,580	0.52	$434,032	0.55	$454,398	0.57

Shipping	$412,163	0.52	$434,032	0.55	$506,920	0.64

^aThe cost of the best case, estimated case, and worst case is divided by the cost of the oxygen system that is currently in place (i.e. Option One - cylinders only)
