Jordan, Amy S., Andrew Wellman, Jill K. Edwards, Karen Schory, Louise Dover, Mary MacDonald, Sanjay R. Patel, Robert B. Fogel, Atul Malhotra, and David P. White. Respiratory control stability and upper airway collapsibility in men and women with obstructive sleep apnea. J Appl Physiol 99: 2020–2027, 2006.

This study assessed the effects of inhaled lignocaine to reduce upper airway surface mechanoreceptor activity on 1) basal genioglossus and tensor palatini EMG, 2) genioglossus reflex responses to large pulses (∼10 cmH2O) of negative airway pressure, and 3) upper airway collapsibility in 15 awake individuals. Genioglossus and tensor palatini muscle EMG and airway pressures were recorded during q...
BACKGROUND This study aimed to investigate the relationship between the inferior vena cava respirophasic variation (IVC collapsibility index [IVCCI]) and the general heart end-diastolic volume index (GEDVI). By determining the above relationship, we could evaluate the utility of IVCCI as an indicator. MATERIAL AND METHODS Forty-two septic patients were finally enrolled in this study. The inferi...
Detection of confounding and confounders is important for observational studies, and especially so for epidemiologic studies. Miettinen and Cook (1981) derived two criteria for detecting confounders. Using a model, Wickramaratne and Holford (1987) proved that the two criteria are necessary but not sufficient conditions for confounders. We take uniform nonconfounding to mean there is no confound...
