Causal analysis of cardiorespiratory coupling on the ISS — Human bodies are best suited to life on Earth. When astronauts travel to space and live in a weightless environment, their cardiorespiratory systems adapt – sometimes in ways that can affect their health. For example, the fluids that circulate in their bodies decrease in volume, which means their blood pressure is lower than on Earth.

Researchers are working to understand more about how astronauts' cardiorespiratory systems decondition when they are in microgravity. CARDIOBREATH looks at what can be done to protect astronauts' blood pressure regulation, by examining how astronauts' cardiovascular and respiratory systems interact with their blood pressure control during missions on the International Space Station.
