内容記述 |
Sleep apnea syndrome (SAS), especially obstructive sleep apnea (OSA) has become more urgent clinical problem in the world because of its risk factor for traffic and occupational accidents, and for cardiovascular disorders. Since OSA is mainly caused by the downward sinkage of the root of the tongue while maintaining a supine posture, sleep posture may affect the incidences of OSA. In fact, it has been observed that a prone posture reduced the occurrence of OSA. However, a prone posture may induce additional stress on respiratory and cardiac activity. In the present study, we examined the effect of sleep posture on respiratory pattern and respiratory muscle activity in healthy male subjects. Five healthy males maintained a relaxed breathing in supine, lateral, and prone postures on a sofa bed for ten minutes each. Respiration, respiratory muscle activity and heart rate were measured during the latter half of each posture. The respiratory parameters; respiratory rate, peak flow velocity, and inspiratory volume were derived from the flow-velocity curve using a pneumotachograph. Respiratory muscle activity (EMG) focused at the intercostal, the diaphragm and the rectus abdominal muscles were measured using surface electrodes, and the root mean square value (RMS) was calculated at each the inspiratory and exspiratory phases. Heart rate (HR) was also calculated from the R to R intervals on the electrocardiogram, and the power spectrogram of the heart rate variability (HRV) was also calculated to assess the energy of high-frequency fluctuation in the spectrogram. The mean HR, the mean HRV and the mean energy of the high-frequency fluctuation of HRV were unchanged among postures. The prone posture enhanced tidal volume, minute ventilation and peak flow velocity compared with those of the supine and lateral postures, although no statistical difference was observed in the respiratory rate and the rate of inspiratory duration against respiration time. Furthermore, no significant difference was observed in the respiratory muscle EMGs measured at the intercostal, the diaphragm and the rectus abdominal muscles. It was concluded that the prone posture might induce additional load especially in breathing, but little to no or slight effect on cardiac activity. Further studies will be required to clarify the clinical applicability of prone posture on OSA patients during sleep. |
