Abstract.

Control of the circulatory and respiratory systems is especially important in severely disabled people. The purpose of this study was to clarify the response of hemoglobin oxygen saturation level (SpO2), pulse rate, and respiratory rate during oral feeding in severely disabled persons. Continuous measurement of these variables was done by pulse oximetry and respiratory inductance plethysmography under two experimental settings in eight severely disabled persons aged 14–28 yrs. Setting I consisted of the following three procedures: (a) a 30-min period in the supine position, (b) a 50-min period in a sitting position, and (c) a 30-min period in the supine position. Setting II consisted of the following four procedures: (a) a 30-min period before the meal in the supine position, (b) a nonspecified period in a sitting position during which the meal was taken, (c) a 30-min period after the meal in the same sitting position, and (d) a 30-min period in the supine position. Results showed that mean SpO2 level decreased and mean pulse rate increased during the meal in almost all subjects. In many cases, pulse rate and SpO2 level did not return to baseline values in the sitting position after the meal. These findings indicate that oral feeding of severely disabled persons in a sitting position places considerable stress on the circulatory system, the effects of which may last after the meal in some cases.

Key words: Oral feeding — Arterial oxygen saturation — Severely disabled people — Deglutition — Deglutition disorders.
