Martin John Tobin (born 23 April 1951) is an Irish-American critical care physician, pulmonologist, and academic who is a recognised expert in acute respiratory failure, mechanical ventilation, and neuromuscular control of breathing.
[1] According to the American Thoracic Society, Tobin is "the supreme scholar of critical care medicine and editor or author of seven extraordinary textbooks on the subject."
[4] Tobin was born in Freshford, County Kilkenny,[5] and attended medical school at University College Dublin (1969-1975) and where he earned a MB BCh BAO.
[3][7][8] Tobin is a pulmonologist at Edward Hines Jr. Veterans Administration Hospital and Loyola University Medical Center near Chicago.
He said: ‘This is the science behind that plot.’ As footnote indicated, the plot was extracted from the article ‘Tracheal stenosis: a flow dynamics study’ by Mark Brouns, Santhosh T. Jayaraju, Chris Lacor, Johan De Mey, Marc Noppen, Walter Vincken, and Sylvia Verbanck, Journal of Applied Physiology 102: 1178– 1184, 2007.
Tobin was called as a rebuttal witness after the defense team's forensic pathologist David Fowler suggested that prolonged inhalation of carbon monoxide (CO) fumes from the police cruiser's exhaust tailpipe could have been a cause-of-death factor.
Tobin cited Floyd's Emergency Room arterial blood oxygen saturation level (98%) as inconsistent with carbon monoxide poisoning.
