Abstract

As patients on bed rest perform repeated Valsalva maneuver, it is necessary for them to prevent the-danger inherent in repeated Valsalva maneuver through intelligent rehabilitative nursing care. In this regard, it seems to be important to furnish a scientific rationale underlying rehabilitative nursing care. This study was undertaken to find the effects of repeated Valsalva maneuver upon circulation of nor-mal men. The subjects for this study were twenty normal and healthy college students of age from 19 to 26. For the first time, the ECG of standard 12 leads was recorded and the blood pressure was measured under the resting state. And the subjects performed Valsalva maneuver for 10 seconds, then expired air for 2 seconds. After the subjects carried out in this menner for 1 minute, the ECG and the blood pres-sure were recorded and measured again. The Changes of heartbeats, systolic and diastolic pressures after the practice of repeated Valsalva maneuver were compared with those of the letting state. The results obtained were as follows : 1. The heartbeats after the practice of repeated Valsalva maneuver generally increased but did not show statistical significance. 2. The systolic pressure measured after the practice of repeated Valsalva maneuver was higher than that of the resting state. 3. The diastolic pressure measured after the practice of repeated Valsalva maneuver was higher than that of the resting state.
