On 27 November 2022, we completed the first stage of our underwater research on the use of the Mobile Medical Module (MMM) to perform cardiopulmonary resuscitation under microgravity conditions. The version of MMM 4.0, developed in the Disaster Medicine and Emergency Department, met all our expectations. Now we are facing detailed tests and research in simulated microgravity.

The authors thank Analog Astronaut Training Center (@astronaut.center) and Safe Diving Academy for their assistance in the first phase of the MMM Project. There is still a lot of hard work ahead of us and lots of fun both underwater and in the air during parabolic flights.
