Biofoam

Biofoam is a self-sealing, space-filling coagulant and an antibacterial, tissue-regenerative foam polymer used by the United Nations Space Command as a form of medical first aid. This foam keeps damaged organs in place and helps stop bleeding and hemorrhaging. Biofoam is inserted into the skin and deeper into the body. It is very painful to use, at least initially, described as feeling like "burning ants crawling around the wound" and "thousands of tiny knives" stabbing the recipient. However, biofoam has been described as being able to numb pain. It is likely that only the application is painful, and that the biofoam quickly numbs the wound after settling. Biofoam does not seem to have this kind of painful reaction when applied to an unwounded area, as the Rookie is seen spraying a small amount on his uninjured fingers and does not react in pain. It is often used as a medical option when there are no medical personnel available. Bottles of biofoam are found in health packs. Often UNSC medics will use it as a sealing agent during treatment in field hospital.

The effects of biofoam are temporary, and after a time, usually a few hours, it simply breaks down. Therefore, it is normally a form of first aid, used only as a temporary sealant until proper medical attention can be sought.

The MJOLNIR Mark VI armor contains automatic biofoam injectors, which negate the need for SPARTANs to use health packs.

Trivia

 * Despite the insertion process being rather painful, when biofoam is applied to Romeo's wound in Halo 3: ODST, he sighs with relief, rather than showing signs of discomfort. This might result from his rigorous ODST training, or be due to his relief that he can breathe properly again.
