Polysomnographic examinations were performed on normal breathers and those with disturbed nasal breathing.1. Plugging of the nares of normal infants during sleep caused hypoventilation with decrease in PaO2. Removal of the obstruction resulted in complete recovery of normal breathing.2. Polysomnograms of children with large adenoids and adults with bilateral nasal polyps showed marked increase in respiratory intraesophageal pressure-change and alternative breathing consisted of apnea and deep breaths with large snores. Corresponding to this breathing pattern, PaO2 and PaCO2 changed in reverse direction to each other. EEG showed the existence of sleep disturbance with stages 2 and 3 predominating.3. Contrast media dripped into the pharynx through a transnasal tube during sleep was found on chest X-ray films in the lungs in 8 of the 10 infants with large adenoids in contrast to only in 1 of the 7 infants with normal nasal breathing.4. Flexible fiberscope examination visualized the vibration of the pharyngeal wall mucosa which closed in on each other. Secretions attached to the surface of the mucosa also joined together.5. The influence of obesity on breathing during sleep was clearly shown on polygraphic recordings. Obesity itself caused narrowing of the upper airway represented with snores in varying degrees. Additional nasal obstruction enhanced the disturbance in ventilation (hypoxia and hypercapnia were intermittently caused by alternation of apnea and deep breaths) and sound sleep (stage 1 and 2 predominance on EEG).6. Surgical removal of the hypertrophied adenoids or nasal polyps relieved nasal obstruction and resulted in normal sleep-EEG and regular breathing patterns which mean sound sleep and normal breathing.It has been clearly demonstrated that disturbance in normal nasal breathing during sleep caused more serious trouble to the subject than while awake, even though this evidence has received little attention in general. Suitable treatment for removal of the obstruction in time is strongly recommended to restore sound sleep and normal respiratory function.
