Work of breathing in exercise and disease
… require little or no volitional effort on behalf of the participants being tested. Specifically to attempt to detach the behaviour of the patient from the accuracy of the test of respiratory function, resulting in techniques that are simpler and easier to administer and undertake for both assessor …

Work of Breathing: Development of a Construct
<p>Critical care nurses are often required to assess a patient’s work of breathing and make clinical decisions based on their findings. There is currently no objective work of breathing assessment tool available. The purpose of this descriptive study was to discover how nurses conceptually describe …

Physiological consequences of the work of breathing and of inspiratory muscle training
… the inspiratory muscles are, in part, the source of these reductions remains unknown. Accordingly, this thesis investigated: (I) the contribution of the respiratory muscles to the systemic [lac-]B and (II) the effects of IMT upon inspiratory muscle lactate exchange and clearance. In addition, the …

Design and Evaluation of a Novel Method to Noninvasively Estimate Tidal Volumes During Administration of Nasal Cannula Therapy
Administration of nasal cannula therapy tasks providers with periodically monitoring their patients and adjusting settings according to patient needs. Conventionally, providers monitor a patient's oxygen demand using pulse oximetry and a qualitative assessment of the patient's work of breathing. …

Optimisation of neonatal ventilation
… evaluated. <br/>Aim: To optimise the delivery of new techniques using physiological outcome measures. <br/>Methods: A series of studies were undertaken. The objectives were: <br/>• In prematurely born infants with acute respiratory distress, to determine the optimal level of volume targeted …

EVALUATION OF TRANSIENT COGNITIVE CHANGES FROM MAXIMAL EXERTION AND RESPIRATOR WEAR
… program is mandated by federal law to protect workers exposed to breathing hazardous atmospheres. Those wearing respirators and/or performing high-intensity physical work may endure physiological and/or psychological impairment from cardiorespiratory stress, respirator anxiety, and working in …

Soft Robotics Applied to the Development of a Diaphragm Assist System
… like speech and swallowing. This thesis works towards a soft robotic alternative that aims to intervene internally at the diaphragm as opposed to the mouth. For medical problems that are mechanical in nature, soft robotics offer a promising solution by coupling advanced robotic control …

Adaptive and neuroadaptive control for nonnegative and compartmental dynamical systems
Neural networks have been extensively used for adaptive system identification as well as adaptive and neuroadaptive control of highly uncertain systems. The goal of adaptive and neuroadaptive control is to achieve system performance without excessive reliance on system models. To improve robustness …

PERFLUOROCHEMICAL AUGMENTED INTRATRACHEAL DELIVERY OF ANTIOXIDANT ENZYMES AND GENES TO ATTENUATE OXIDATIVE STRESS-INDUCED LUNG AND RESPIRATORY MUSCLE ALTERATIONS
Supraphysiologic concentrations of oxygen are used in the management of critically ill patients across the lifespan. However, hyperoxia (HO) results in alveolar- capillary membrane destruction, pulmonary edema, pleural effusions, infiltration and activation of inflammatory cells, altered pulmonary …
