Rejection Quick Reference: Refers to the rejection of transplanted organs.
Advanced Reference: Involves the host forming antibodies against the transplanted tissue, leading to eventual rejection.
Relative humidity Quick Reference: This is the ratio of the mass of water vapour in a given volume of the air to the mass.
Advanced Reference: Relative humidity is the absolute humidity divided by the amount present when the gas(air) is fully saturated at the same temperature and pressure. Applicable to theatre environment where it should be approximately 50% to 55% and measured with a hygrometer.
Relaxant Quick Reference: Refers to muscle-relaxant drugs. To paralyse the patient.
