Question

Which gas is used in hospitals for storing and preventing blood and tissues?

Answer 1

• Medical nitrogen in liquid form is mainly used in hospitals for cryosurgery.
• They find use in surgery for the removal of cancers, and skin lesions and for storage of tissues, cells, and blood samples.
• Nitrogen helps in storing these samples in cryogenic temperatures to prevent oxidation.
• The cryogenic temperature range has been defined as from −150 °C to absolute zero (−273 °C), the temperature at which molecular motion comes as close as theoretically possible to ceasing completely.
• Therefore nitrogen gas is used in hospitals for storing and preventing blood and tissues.
