A cardiac tissue donor's time and date of death was 2100 on 03/19/06, and the heart was placed into cold storage at 2300 on 03/19/06. The heart recovery began at 0320 on 03/20/06 and was placed into transport solution at 0445 on 03/20/06. The heart arrived at the processing facility at 1035 on 03/20/06 and was placed into disinfection solution at 1215 on 03/20/06. The grafts completed their controlled-rate freezing cycle at 1545 on 03/21/06.

What is the cold ischemic time?

a. 2 hours
b. 5 hours 45 minutes
c. 7 hours 30 minutes
d. 13 hours 15 minutes

Answer :

Final answer:

The cold ischemic time is 10 hours.

Explanation:

The cold ischemic time is the duration between the time the heart stops functioning and the time it is placed into a cold storage or transport solution. In this case, the cold ischemic time can be calculated as follows:

  • Time between death and placement in cold storage = 0 hours and 20 minutes
  • Time between cold storage and heart recovery = 4 hours and 20 minutes
  • Time between heart recovery and placement in transport solution = 1 hour and 25 minutes
  • Time between transport solution and arrival at processing facility = 5 hours and 50 minutes
  • Total cold ischemic time = 0 hours + 4 hours + 1 hour + 5 hours = 10 hours
