Intravenous hydration is required, and should be given through an infusion pump so that therate is optimally controlled. All facilities must have readily accessible resuscitation equipment. Chill berths above TL 12 usually have built-in automeds, or provision for these to be installed. Water is at its maximum density. Bacterial and fungal growth is maximally inhibited.
Fast drug takes about two months or sixty days to be eliminated.
Agents which can safely reverse the effect before this time are not developed until TL 12. It is generally realised that the size of water crystals formed is the main determinant of successful revival from freezing. The development of compounds which depress the freezing point of water without being toxic to an organism enables the first successful revival from cryogenic freezing at about the same time as the development of hibernation. Cryogenic freezing technology becomes known as vitrification, as tissue water is changed to a supercooled liquid and then a solid with falling temperature. Installing a patient into low berth in the early days was equivalent to connecting them to life support.
