Adaptive Closed-Loop Neuromorphic Controller For Use In Respiratory Pacing, Ricardo Siu
FIU Electronic Theses and Dissertations
Respiratory pacing can treat ventilatory insufficiency through electrical stimulation of the respiratory muscles, or the respective innervating nerves, to induce ventilation. It avoids some of the adverse effects associated with mechanical ventilation such as risk of diaphragm atrophy and lung damage. However, current respiratory pacing systems provide stimulation in an open-loop manner. This often requires users to undergo frequent tuning sessions with trained clinicians if the specified stimulation parameters are unable to induce sufficient ventilation in the presence of time-varying changes in muscle properties, chest biomechanics, and metabolic demand. Lack of adaptation to these changes may lead to complications arising …

Cuffed Pediatric Endotracheal Tubes, Jennifer Nutter, Emmanuela Oppong, Colleen Pouliot
Honors Theses
Endotracheal tubes (ET) are used to provide patients with an adequate airway when they are unable to breathe on their own. ET tubes can be used in emergency situations, surgical procedures, and on-floor intubations. The two main types of ET tubes are cuffed and uncuffed. Due to the fragile structure of a child's throat, uncuffed tubes are primarily used in pediatric patients. Uncuffed tubes can slip out of place resulting in air leakage and improper oxygenation. In contrast, cuffed ET tubes provide a proper seal to the airway and prevent against aspiration. The following work proposes an improved design for …

The Second Wind device is a set of sensors and a data processing unit capable of recording data necessary to conduct a simplified version of a complex cardiopulmonary stress test (CPET). This data includes VO2, VCO2, ventilation, and pulse oximetry data. VO2 and VCO2 are the percent, by volume, of oxygen and carbon dioxide in the patient's breath, spirometry is the measure of air flow, and the pulse oximetry data includes heart rate (HR) and percent oxygen in the blood (SpO2). In addition, the device was designed to be portable, so this test could be run from patients’ homes or …
