EVALUATION OF A PERSONAL MOBILE TRAINER SYSTEM DESIGNED FOR FACILITATING EXERCISE THERAPY FOR TRAUMATIC BRAIN INJURY PATIENTS
Turki, Ahmad Fawzi G; 0000-0002-1328-9937 (2021-08-16)There are no effective pharmacological agents that can prevent or treat post-TBI cognitive deterioration. Previous research has shown that exercise can be an effective means of enhancing the patients condition with mild ... -
Influence Of Hypoxia, Hypercapnia And Inspiratory Efforts On Sympathoexcitation During Apnea
Rao, Vikram (Biomedical Engineering, 2008-09-17)Obstructive Sleep Apnea (OSA) is characterized by frequent periods of apnea resulting in hypoxia, hypercapnia and fluctuations of intrathoracic pressure (inspiratory efforts). Hypoxia, hypercapnia and inspiratory efforts ... -
An Investigation Of Concurrent Variations In Blood Oxygen Saturation And Cerebral Blood Flow During Apnea
Swittens, Jennifer (Biomedical Engineering, 2013-07-22)Sleep apnea derived from Greek word "apnoia" which means "without air or temporary interruption in breathing", is a sleep - associated breathing disorder that involves a decrease or complete stop in airflow despite a ... -
Investigation Of End-tidal Carbon Dioxide (ETCO₂) And Heart Rate Variations During Sleep Apnea
Bashaboyina, Aditya (Biomedical Engineering, 2010-11-01)Sleep Apnea is a sleep disorder where limitation or cessation of breathing occurs. It is characterized by abnormalities in the respiratory pattern and quantity of ventilation during sleep. According to a study 4% of men ... -
INVESTIGATION OF FUNCTIONAL CONNECTIVITY AND NEUROVASCULAR COUPLING IN DIFFERENT VIGILANCE / BREATH-HOLD STATES OF THE BRAIN FROM SIMULTANEOUS EEG-fNIRS MEASUREMENTS
Babawale, Olajide (2019-07-10)Functional connectivity and neurovascular coupling are important phenomena that occur in the brain. Functional connectivity is the study of functional brain networks and their characteristics. While neurovascular coupling ... -
An Investigation Of Peripheral Blood Volume And Oxygen Saturation Change In Obstructive Sleep Apnea
Iyer, Swathi (Biomedical Engineering, 2010-11-01)Obstructive sleep apnea (OSA) is a type of sleep disordered breathing in which the airway collapse partially or fully and causes arousal to resume breathing. In a 2009 National sleep foundation poll of 1000 people, 63% ... -
An Investigation Of Support Vector Machine Classifier In Detecting Nocturnal Airway Obstruction From Spontaneous Heart Rate Combined With ECG Morphology Changes
Ravi, Harshan (Biomedical Engineering, 2011-10-11)Sleep apnea is a sleep disordered breathing resulting from limitation or cessation to breathing for 10 or more seconds. The prevalence of sleep apnea has increased exponentially in the past decade. The increase in epidemic ... -
An Investigation Of The Covariations Between Variations In Exhaled Carbon Dioxide And Cerebral Blood Flow Levels During Apnea
Kanal, Varun AjaySleep apnea is a breathing disorder characterized by repetitive reduction or cessation of breathing during sleep. It is estimated that that around 17% of adults suffer from mild to severe sleep disordered breathing. The ... -
An Investigation Of The Effect Of Obstructive Sleep Apnea On Cerebral Hemodynamics In Relation With Systemic Hemodynamics
Alex, Raichel MaryObstructive Sleep Apnea (OSA) is a major sleep disorder affecting approximately 18 million adults in the US. Recent studies have observed cognitive impairments and brain structural changes in OSA subjects where these ... -
