Full description

The source of data for this study was from a sheep model being treated for smoke-induced acute lung injury using veno-venous extracorporeal membrane oxygenation, a form of extracorporeal life support (ECLS) developed to complement the treatment of acute lung injury in humans. During this type of ECLS, venous blood is carried from the patient to a gas exchange device where it becomes enriched with oxygen, has carbon dioxide removed, and is returned to the patient’s circulation in the right heart. This method can be used for treatment, as respiratory support during lung transplantation, and in critically ill patients with potentially reversible respiratory failure.
The source study was an ongoing publicly funded animal experimentation study (Queensland University of Technology Animal Ethics Approval No. 110000053).
The overall goal of the study was to provide useful information relevant to the sheep model, itself, and to those interested in large animal experimentation and veterinary medicine, generally. The specific objectives were: 1) use the raw data from the sheep model study to create a data management system for tabulating large data sets from human studies using animal models and, 2) analyse that data to provide biological information that is not currently available for sheep receiving ECLS following smoke-induced acute lung injury.
Data from 19 adult mechanically ventilated ewes undergoing intensive care in a previous study evaluating a form of extracorporeal life support (treatment) for acute lung injury were used to develop a comprehensive method for processing manual and electronically gathered clinical observations. Eight sheep were injured by acute smoke inhalation prior to treatment (injured/treated), while another eight were not injured but treated (uninjured/treated).
