Pulmonary inflation pressure (Ppi) was monitored in five animals and the responses to i.v. histamine and to i.v. histamine plus a low-voltage vagus nerve stimulation (VNS) treatment compared. In the comparisons on the left, VNS was applied for 20 sec before and continued through the administration of i.v. histamine (Continuous VNS). In the comparisons on the right, the low-voltage VNS treatment was applied for 30 sec and then discontinued for 10 sec prior to administration of i.v. histamine (Interrupted VNS). *p < 0.05.
