Final answer:
Organs from brain-dead patients require oxygenation and blood circulation via artificial means or devices like the TransMedic Organ Care System to remain viable for transplantation. This system helps in extending the time organs can be used and improves transplant success rates.
Step-by-step explanation:
To maintain the health of organs for donation from brain-dead patients, several measures are taken, including the maintenance of adequate oxygenation and perfusion, and the use of technological solutions such as the TransMedic Organ Care System. Brain-dead patients require medical intervention to keep organs viable for transplantation. Organs must be oxygenated and have blood circulation maintained through artificial means. Devices like the Organ Care System can extend the viability of organs, particularly the heart.
It warms the heart and pumps oxygenated blood through it, keeping the organ in a near-physiological state for up to 12 hours, thus expanding the window of time for a heart to be transported and transplanted. This also lowers the risk of the organ being rejected by the recipient's immune system and increases success rates for transplants.
