Abstract The findings of this thesis represent a novel aspect in lung ventilation imaging involving a series of experiments with a new apparatus known as the Technegas Easy Breather Accessory (TEBA). The investigations were undertaken with both normal and Chronic Airways Limitation (CAL) volunteers and with Intubated Intensive Care patients.

The data presented in this research were collected from 144 patients in total. In experiment one there were 25 normal volunteers who underwent conventional ventilation imaging and 25 normal volunteers who underwent TEBA assisted ventilation imaging, while in experiment two, there were 25 volunteers with CAL for conventional ventilation and 25 for TEBA; in experiment three, 25 intubated Intensive Care Patients successfully completed ventilation scintigraphy using TEBA. For experiment four, 20 patients volunteered to complete a Technegas ventilation study prior to their bronchoscopy procedure.

Experiments one and two demonstrated that TEBA was effective in distinguishing normal lung ventilation from ventilation defects found in Chronic Airways Limitation (CAL) and Pulmonary Embolism (PE). Experiment three showed TEBA ventilation imaging could be successfully undertaken by intubated and unconscious patients. This has significant implications for the diagnosis and treatment for patients in ICU who formerly could not undergo this procedure. The results of this experiment will have implications for improving the diagnosis and treatment of patients in critical care.

The findings of this thesis provide further evidence for the first line role of lung scintigraphy in the diagnosis of Pulmonary Embolism (PE). This is of vital importance to the large number of patients who are at risk from the life-threatening diseases of PE and Deep Venous Thrombosis (DVT). This is because timely lung ventilation imaging in the diagnosis and follow-up phase of these diseases will reduce the clinical uncertainty in directing treatment and consequently lower health care costs.
