Abstract:

An automated system for quantitative respirator fit testing by negative pressure was evaluated by comparison testing with a computerized aerosol fit test system (Dynatech Frontier Model 260A). The new negative pressure system measures leakage flow while inspiratory pressures are sustained in a respirator facepiece rather than by pressure decay. Four phases of comparison testing were graduated by level of control, ranging from non-subject tests with hypodermic needle leakages to fit tests of 125 Air Force personnel. Throughout the series of tests, negative pressure fit factors were consistently

Abstract:

Physiologic and Extracorporeal Shock Wave Lithotripsy (ESWL) data were collected before, during and after ESWL from four patient groups employing different anesthetic techniques (epidural anesthesia, general anesthesia with low-volume conventional mechanical ventilation or with unsynchronized high frequency jet ventilation (HFJV) or with HFJV synchronized to the heart rate). The primary goal was to determine if synchronized HFJV had any beneficial effects. A synchronization unit was fabricated that triggered one HFJV breath, per heart beat, delivered 30 milliseconds after the shock wave. This

Abstract:

A negative pressure quantitative fit testing device was used to test the effect exercise protocol has on leakage rates into a negative pressure respirator. Modified exercise protocols were developed for use with the negative pressure system. Aerosol data was analyzed to determine the effect exercises have had on leakage rates using other QNFT systems. Results show that the position of the head affects the amount of leakage into the facepiece. Mean leakage into the respirator mask increased for all positions tested in one phase of the study. However, statistical analysis of the data showed that

Abstract:

This study determined the parameters which affect the internal mask inspiratory pressure and flow rate during respirator wear. The average inspiratory pressure and inspiratory flow rate were measured on 30 subjects who performed various submaximal work rates on a cycle ergometer while wearing air purifying respirators. The half-mask and full-face respirators were equipped with three levels of cartridge resistance. The results indicated that work rate, cartridge resistance, and mask type affected the inspiratory pressure and flow rate significantly. The findings of this study would allow the qu

Abstract:

Firefighting operations are characterised by high time pressures, a high degree of task and environment uncertainty, life-or-death situations, and the continuous emergence of novel events. Despite this, the factors considered most demanding to firefighters and the strategies that lead to effective management of physiological and psychological stressors at the fire scene are yet to be fully understood. To address this issue, study 1 utilised a qualitative approach employing a series of focus groups and individual interviews to establish the operational tasks considered to be most demanding by f

While patients with Obstructive Sleep Apnea Syndrome (OSAS) commonly have depressive symptoms, evidence about the link between OSAS and depression has been inconsistent. Similarly, while Continuous Positive Airway Pressure (CPAP) treatment for OSAS has been claimed to be effective in ameliorating depressive symptoms, results of the impact of CPAP on depressive symptoms have been inconclusive. This thesis describes two studies which aim to contribute to the clarification of these issues.
