Does Increasing Flow To A High Flow Nasal Cannula Affect Mean Airway Pressure In An In Vitro Model?, Robert Brent Murray
Does Increasing Flow To A High Flow Nasal Cannula Affect Mean Airway Pressure In An In Vitro Model?, Robert Brent Murray
Respiratory Therapy Theses
DOES INCREASING FLOW TO A HIGH FLOW NASAL CANNULA AFFECT MEAN AIRWAY PRESSURE IN AN IN VITRO MODEL? Introduction: High-flow nasal cannulas (HFNC) have become popular with many institutions for administration of oxygen (O2). HFNCs are also being used in pediatric and neonatal populations for administration of continuous positive airway pressure (CPAP) as a treatment for respiratory distress. Adult patients are being treated with HFNCs in a effort to provide a high percentage of O2 and correct hypoxemia and other related conditions. The purpose of this study was to examine the effect of increasing flow via a HFNC to an …
Correlational Study For Predictor Variables Affecting Duration On Bubble Cpap, Alison Louise Stoeri
Correlational Study For Predictor Variables Affecting Duration On Bubble Cpap, Alison Louise Stoeri
Respiratory Therapy Theses
Bubble CPAP (BCPAP) is used in the neonatal intensive care unit (NICU) as a form of non-invasive ventilation and is commonly employed in neonates demonstrating respiratory distress. BCPAP may be used to avoid the need for intubation and mechanical ventilation thereby reducing lung injury and other morbidities as well as decrease hospital stay. PURPOSE: The purpose of this study is to retrospectively investigate the length of stay on bubble CPAP (BCPAP) considering gestational age, birth weight, and surfactant delivery in the neonatal population born at an urban tertiary high load level three (NICU). METHODS: A retrospective study using existing data …
The Effect Of Compliance Changes On Delivered Volumes In An Adult Patient Ventilated With High Frequency Oscillatory Ventilation: A Bench Model, John England
Respiratory Therapy Theses
Clinical concerns exist regarding the delivered tidal volume (Vt) during high-frequency oscillatory ventilation (HFOV). HFOV is increasingly being used as a lung protective mode of ventilation for patients with Adult Respiratory Distress Syndrome (ARDS), but caution must be utilized. The purpose of this study was to investigate the effect of airway compliance on Vt delivered by HFOV to the adult patient. Method: An in vitro model was used to simulate an adult passive patient with ARDS, using a high fidelity breathing simulator (ASL 5000, IngMar Medical). The simulation included independent lung ventilation with a fixed resistance and adjustable compliance for …
The Effects Of Aerosol Drug Delivery On Airway Resistance Through Heat-Moisutre Exchangers, Matthew Thomas Hart
The Effects Of Aerosol Drug Delivery On Airway Resistance Through Heat-Moisutre Exchangers, Matthew Thomas Hart
Respiratory Therapy Theses
Introduction: The use of heat moisture exchangers (HMEs) is becoming more popular with many institutions delivering aerosolized medications between the HME and the endotracheal tube of patients being mechanically ventilated. When HMEs become saturated resistance can increase which can cause changes that can lead to patient-ventilator dysnchrony, development of intrinsic PEEP, and weaning difficulty. The purpose of this study was to determine the effects of aerosol drug delivery on resistance through heat-moisture exchangers. Method: An in-vitro model to simulate exhaled heat and humidity from a patient’s lungs was developed by connecting the test lung to a cascade humidifier that was …
How Does Alteration Of Airway Resistance Affect Delivered Tidal Volume In Adult Patients Receiving High-Frequency Oscillatory Ventilation?, Essam Ali Aljamhan
How Does Alteration Of Airway Resistance Affect Delivered Tidal Volume In Adult Patients Receiving High-Frequency Oscillatory Ventilation?, Essam Ali Aljamhan
Respiratory Therapy Theses
Concerns exist regarding the ability of HFOV to provide the needed lung protective ventilation for adult patients with ARDS. HFOV is increasingly being used as a lung protecting ventilation mode even if some of its protective attributes may be lost as the airway resistance (Raw) increases or decreases. In fact, in cases of shifting air resistance, HFOV may have caused lung injury. PURPOSE: The purpose of this study was to investigate the effect of airway resistance on tidal volume (Vt) delivered by HFOV to adult patients. Also, the study intended to determine direction for volume change when resistance increases or …
