Roscosmos cosmonauts Anna Kikina and Pyotr Dubrov practice CPR in microgravity
iss075e0088769 (Sept. 4, 2026) --- Expedition 75 flight engineers Anna Kikina and Pyotr Dubrov, both Roscosmos cosmonauts, practice CPR in the weightless environment of the International Space Station. Conducting chest compressions in microgravity requires securing the patient with restraints while the crew member braces their feet against a fixed surface to generate effective force.
