Research Focus: 

Dr Magder has had a long standing interest in Heart-lung interactions and the control of cardiac output. Early studies were on respiratory muscle blood flow and vascular regulation. He has emphasized the importance of the use of central venous pressure and cardiac output to better manage the use of fluids.  His studies have been both in animal models and human subjects. His basic research has included studies on the role of the endothelium in the sepsis-induced abnormalities of vascular dysfunction. This has included studies on the cellular signalling responses to nitric oxide, oxygen radicals and oestrogen. He also has an ongoing interest in acid-base balance and fluid and electrolyte management.
