Dr. Matt Morgan, a Consultant in Intensive Care Medicine, discusses the significance of comparative physiology in understanding respiratory therapies in the ICU. He explores the unique breathing mechanisms of animals such as frogs, giraffes, and peregrine falcons, emphasizing the importance of comparative physiology in treating critically ill patients. He also delves into the concept of One Medicine and its connection to breathing characteristics of the Bedwin Spiny Tailed Lizard.
Understanding the natural breathing mechanisms of animals, like frogs, can inform respiratory therapies in the ICU.
Studying respiratory adaptations in animals, such as the Peregrine Falcon and Bedwin Spiny Tailed Lizard, can provide valuable insights for improving patient care in critical care settings.

Comparative Physiology and ICU: A Rebirth of Physiology
Dr. Matt Volgan discusses the importance of physiology in critical care and how it complements clinical research. He highlights the concept of 'physiology 2.0' and the value of understanding physiology in treating critically ill patients. Drawing examples from animals like frogs, he explains how positive pressure ventilation, which is now commonly used in humans, has been a natural breathing mechanism for frogs for millions of years. He also explores how giraffes utilize respiratory physiology to minimize dead space and maintain cerebral perfusion under challenging anatomical constraints.
Learning from Peregrine Falcon and Bedwin Spiny Tailed Lizard
Dr. Volgan shares insights from the Peregrine Falcon and Bedwin Spiny Tailed Lizard and their relevance to patient care. He draws a connection between high-flow nasal oxygen therapy and the Peregrine Falcon's diving technique, highlighting how the falcon protects its eyes, ears, and nasal passages during high-speed dives, which can inform patient care strategies. Additionally, he discusses the respiratory pattern of the Bedwin Spiny Tailed Lizard, which closely resembles the ventilator trace observed in humans with severe respiratory failure. Understanding these animal physiological adaptations can provide valuable insights for improving patient care in critical care settings.
In this episode we welcome back good friend, Dr. Matt Morgan.
Dr. Morgan is a Consultant in Intensive Care Medicine at the University Hospital of Wales, UK and The Royal Perth Hospital, Australia. He is an adjunct Clinical Professor at Curtin University, an Honorary Senior Research Fellow at Cardiff University and regular columnist at the BMJ. In his off time, he has penned 2 books thus far. In his is first book “Critical" he tells the remarkable stories of patients he has met as a guide through the intensive care unit. His second book, "One Medicine", explores how understanding the lives of animals can help treat human disease.
In this episode, recorded remotely from Perth, Australia, Matt highlights animal physiology to help understand respiratory therapies in the ICU.
