What is the device utilization ratio for a facility that has 600 ventilator days and 3,000 patient days?

• A. 0.1
• B. 0.2
• C. 0.3
• D. 0.4

Answer: (B)

The device utilization ratio is calculated by dividing the number of ventilator days by the total patient days. Here, 600 ventilator days divided by 3,000 patient days equals 0.2, so the ratio is 0.2. This means the ventilator is used on 20% of patient days. This metric helps gauge how intensively ventilators are being used relative to patient volume; the other numbers would result from different input values.
