A respiratory pneumobelt was used to record chest wall movement and was placed around the chest at the inferior edge of the sternum near the xiphoid process.
For abdominal muscle stimulation alone, abdominal pressures are high and pneumobelt records show large upper-chest expansions during stimulation.
At age 39, noninvasive ventilatory assistance was provided by a Pneumobelt
system (18) (18 breaths/minute from 10 p.
During the first 48 hours of life the subject was placed in a special crib in the laboratory; electrodes were placed on the chest and leg to monitor heart rate, a pneumobelt
encircled the abdomen to record respiration and activity level was monitored by a strain-gauge stabilimeter.
In addition, the paradoxical expansion of the abdominal pneumobelt during abdominal muscle stimulation (Figure 3) in the supine position may not occur in the prone position.
Respiratory pneumobelts were placed on the midthorax and midabdomen to record movements of the thoracic and abdominal compartments.
