Intrapulmonary and intracardiac shunting with exercise at altitude.

Conference item

Recent studies in normal participants have shown that right to left shunt blood vessels in the lung open up during exercise. We describe the first field study to investigate this phenomenon at altitude. This study aimed to assess the effect of altitude and partial acclimatization on inducible right to left shunting at rest and with exercise. A contrast-enhanced transcranial Doppler imaging technique to detect microbubbles after injection of blood and saline agitated with air was used to measu...
