A 42-year-old male who complained of snoring and sleep apnea was studied with the simultaneous measurement of both cardiovascular parameters and mesopharyngeal pressures at the upper and lower sites at the base of the tongue. The data demonstrated that the upper airway was severely obstructed at the base of the tongue and cardiovascular disturbances were also associated. Nasal continuous positive airway pressure (Nasal CPAP) therapy was performed and the symptoms disappeared.<BR>Nasal CPAP sufficient to releave sleep apnea an d fluctuation of blood pressure, prevent reduction of oxygen saturation, and remove upper airway obstruction and change of fingertip blood flow was respectively differentiated and the lowest positive pressure needed to avoid upper airway obstruction and cardiovascular disturbances was determined.<BR>The measurement system is thought to be clinically useful and relia b le for evaluation of cardiovascular abnormalities with upper airway obstruction and determination of optimal value of nasal CPAP.
