The Med-Bed Rest status effect is assigned to Duplicants who are resting in a Med-Bed. A Med-Bed must first be assigned to a patient Duplicant, then they will travel there for a rest. Duplicants' injury and disease recovery times are improved.
An available Duplicant can treat the patient Duplicant to increase this bonus. (See Receiving Treatment)
If a patient leaves a Med-Bed that's assigned to them, they lose all medical status effects and gain Runaway Patient.
