Indirect Calorimetry: The Effects Of Overfeeding And Underfeeding Mechanically Ventilated Patients, Hailee Schirm Jan 2025

Indirect Calorimetry: The Effects Of Overfeeding And Underfeeding Mechanically Ventilated Patients, Hailee Schirm

Williams Honors College, Honors Research Projects

This research focuses on the effects of overfeeding and underfeeding mechanically ventilated patients in the ICU and how indirect calorimetry plays a role in improving patient outcomes. Research was pulled from eight peer reviewed sources written within the last ten years to support this statement. It includes multiple types of studies including but not limited to a retrospective cohort study, meta-analysis, review, and deterministic cost-sequences analysis. Indirect calorimetry measures carbon dioxide production and oxygen consumption to calculate energy expenditure and determine the number of calories needed to sustain one’s body. This allows us to determine the number of calories a …


The Accuracy Of Recreational Athletes In Self Detecting Ventilation Threshold During A Maximal Exercise Test, Andrew Biegner Jan 2023

The Accuracy Of Recreational Athletes In Self Detecting Ventilation Threshold During A Maximal Exercise Test, Andrew Biegner

Williams Honors College, Honors Research Projects

INTRODUCTION: Ventilatory threshold (VT) is where minute ventilation (VE) increases nonlinearly with increasing exercise intensity. Prior studies have shown that subjects can recognize VT by changes in breathing during exercise. Teaching recreational athletes to use VT as a training method could result in better quality training. PURPOSE: Determine if recreational athletes can accurately perceive changes in ventilation associated with VT during maximal exercise testing. METHODS: Subjects were recruited (n=20, age= 20.5 ± 1.7 yrs.) to participate in the study. Subjects performed a modified maximal treadmill protocol with gas analysis. Subjects indicated when they noticed a considerable change …


Mouthpiece For Patients With Neuromuscular Disorders, Rebekah Starkey, Carissa Thompson, Michael Dickens, Andrew Pero Jan 2023

Mouthpiece For Patients With Neuromuscular Disorders, Rebekah Starkey, Carissa Thompson, Michael Dickens, Andrew Pero

Neuromuscular Disorders (NMDs) impact people throughout the world. An early hallmark of these disorders includes some degree of facial muscle weakness. Respiratory testing is important to evaluate the progression of these patients’ NMDs. However, these tests require that the patient purses their lips around a mouthpiece to create a tight seal. This is a difficult task for one with facial muscle degeneration. This often leads to results that fail to reflect the patient’s true respiratory ability and prevents their physician from providing the appropriate degree of care. The objective of this project was to develop a face mask or mouthpiece …


Neurally Adjusted Ventilatory Assist: Summation Of The Safety Proofs And Benefits, Landry Carneal Jan 2021

Neurally Adjusted Ventilatory Assist: Summation Of The Safety Proofs And Benefits, Landry Carneal

Williams Honors College, Honors Research Projects

Neurally Adjusted Ventilatory Assist (NAVA) is a mode of ventilation that is triggered by neither flow nor pressure but by the electrical activity of the diaphragm (Stein & Firestone, 2018, p. 227). NAVA puts ventilatory control into the hands of the patient and is often used in neonates who are more challenging to ventilate. Medical practitioners, however, are skeptical to put this mode of ventilation into practice with fear that neonates are neither strong enough nor capable to manage their own respiratory efforts without hypoventilation or damage to the lungs (Lubarsky et al., 2020, p. 3). Research shows that despite …


Åstrand-Rhyming And Ymca: A Compare And Contrast Literature Review Of Two Submaximal Cycle Ergometer Tests, Sean Roberts Jan 2019

Åstrand-Rhyming And Ymca: A Compare And Contrast Literature Review Of Two Submaximal Cycle Ergometer Tests, Sean Roberts

Williams Honors College, Honors Research Projects

In the world of exercise prescription there are two major protocols that are used to test an individual’s aerobic capacity at a submaximal intensity using a stationary bicycle. These protocols require participants to exercise at a constant work rate until a specified hear rate is reached. Data can then be analyzed to determine the participant’s aerobic capacity. The objective of this literature review is to look at these two tests – the Åstrand-Rhyming cycle ergometer test (ARCET) and the YMCA cycle ergometer test – and determine if one is better than the other for different populations and which one an …


Quickcough: An Instrumentational Proximal Airway Clearance Technique (Act) For Select Patients With Neuromuscular Disease (Nmd), Sean X. Sullivan, Russell K. Catania, Madison K. Plaster, Sydney E. Kandray, Mariah Costa Jan 2019

Quickcough: An Instrumentational Proximal Airway Clearance Technique (Act) For Select Patients With Neuromuscular Disease (Nmd), Sean X. Sullivan, Russell K. Catania, Madison K. Plaster, Sydney E. Kandray, Mariah Costa

Williams Honors College, Honors Research Projects

Patients with neuromuscular disease (NMD) requiring tracheostomy and mechanical ventilation secondary to respiratory failure encounter increased difficulty in removing pulmonary secretions from the airways. To combat issues associated with current treatment modalities for insufficient cough efficacy (cost, poor mobility, discomfort, lack of evidence), we have developed an instrumentational proximal airway clearance technique (ACT) which augments a manual proximal ACT developed by a client with NMD. QuickCough is a 3D-printed PLA attachment to the tracheostomy apparatus which has demonstrated its ability to facilitate pressure changes necessary to increase patient’s peak cough flow (PCF) by providing a stronger exsufflation for the patient. …
