Medical Evacuation

Medical Evacuations (often called Medevacs) are rare instances where an emergency forces a Contestant to be removed from the game without being voted out. For a medical evacuation to occur, the medical staff will be called in to assess the contestant's condition and decide whether or not they are fit to continue in the game.

Big Brother Canada 2:
The first and only time in Big Brother history where a houseguest had to be Medically Evacuated was during season two of Big Brother Canada where Week 5 HOH Baka had a medical emergency right before the live eviction when he got too "hyped" which caused his heart to stop, Baka ended up passing out and had to be taken to the hospital and be removed from the game immediately for his health and safety. Baka ended up making a full recovery.
