What is required at all times for certain organ donors to prevent damage to the organs?

• A. Blood pressure maintenance
• B. Oxygen
• C. Temperature control
• D. Fluid replacement

Answer: (B)

For certain organ donors, maintaining oxygen supply to the organs is crucial to prevent damage. Organs, particularly the heart, lungs, liver, and kidneys, rely heavily on oxygen to maintain cellular function and integrity. When organs are deprived of oxygen, they begin to experience ischemia, which can lead to cellular death and disqualify the organs for transplantation.

The continuous supply of oxygen helps ensure that the organs remain viable and functional until they can be harvested and transplanted. This is especially important during the critical period after a donor has been determined but before the organ retrieval process. Ensuring adequate oxygenation can involve various support measures, such as maintaining ventilation and circulation, which contribute to overall organ preservation.
