Hypoxic pulmonary vasoconstriction (HPV) matches lung perfusion with ventilation to optimize pulmonary gas exchange. However, it remains unclear whether acute HPV (occurring within seconds) and the vasoconstrictor response to sustained alveolar hypoxia (developing over several hours) are triggered by identical mechanisms. We investigated the effect of(More)
BACKGROUND The sources and measurement of reactive oxygen species (ROS) in intact organs are largely unresolved. This may be related to methodological problems associated with the techniques currently employed for ROS detection. Electron spin resonance (ESR) with spin trapping is a specific method for ROS detection, and may address some these technical(More)
