UPPER AIRWAY MUSCLE ACTIVITY AND LUNG VOLUME DURING STABLE AND PERIODIC BREATHIN

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The specific aim of this study is to determine whether upper airway muscle activity or lung volume differs between periods of stable sleep/breathing and periods of cyclical breathing in OSA patients. The hypothesis is that differences in upper airway dilator muscle activity and/or end expiratory lung volume contribute to the variability of apnea severity within and between sleep stages in a given patient with OSA.
