These patients were then evaluated on the mechanical ventilator, without rocking bed, and again there was a wide variability in response. All but one patient showed a dramatic improvement in their sleep quality and gas exchange. In one patient (No. 1), even though there was improvement in gas exchange, sleep quality did not improve.
Group 2 Patients
There was a marked variability in the quality of sleep in these patients varying from extremely poor to within normal limits. Three of the eight patients (group 2a) had results within normal limits. The remaining patients (group 2b) had varying degrees of sleep apnea and hypopnea with poor sleep quality. One of these patients with an apnea hypopnea index of 11.1, had little resultant sleep disruption (Table 3).
Four of the five group 2b patients had a snoring history. One patient did not know whether she snored. One of the patients (No. 9) had an elevated hemoglobin value with symptoms of fatigue, excessive daytime sleepiness, and ankle edema of unknown etiology. He was found to have mild obstructive sleep apnea. buy diabetes drugs
Two patients (No. 10 and 11), with a history of bulbar polio, were found to have mild obstructive sleep apnea which was most severe in REM sleep. In both these patients, the vocal cords were found to be paralyzed and accounted for the obstructions. There was an audible high pitched stridorous noise present in one of the patients when she experienced obstruction while she slept.
