Mice perform CPR-like rescue on their fellow rodents, according to a study conducted by researchers in California.
The study observed that mice helped their unconscious peers by opening their mouths and providing oxygen, resembling how humans perform Cardiopulmonary Resuscitation (CPR).
A scientific journal led by Huizhong Whit Tao stated, “clearance of foreign objects from the mouth, improved airway opening, and hastened recovery suggested reviving-like efforts.”
Researchers found that this behavior triggers the release of oxytocin hormones, a substance linked to social bonding, which is activated when mice encounter an unconscious companion.
“Assisting unresponsive group members may be an innate behaviour widely present among social animals,” the study noted.
Further research indicated that, similar to elephants, dolphins, and chimpanzees, mice exhibit an instinctive tendency to help others in medical emergencies.
Mice were also observed engaging in remarkable actions such as carrying, stroking, and cradling their distressed companions.
The study highlighted how rodents efficiently remove obstructions from the mouths of their peers to restore breathing when they lose consciousness.
Scientists confirmed that 80% of the observed cases were successful, as mice consistently applied the same method of clearing airway blockages in their peers.
The University of Colorado emphasized that these findings showcase the natural inclination of animals to help one another, stating that such behaviors are “shared by many other species.”
