ventricular fibrillation did not occur.4 eight out of 10 dogs brought to the verge of a fatal response with 10 % oxygen : 90 % nitrogen and repeated doses of isoprenaline ( 2.5 mug/kg ) were resuscitated by the administration of 100 % oxygen and , when necessary , cardiac massage.5 a group of five dogs survived the combined effects of repeated doses of isoprenaline ( 2.5 mug/kg ) and respiration with 10 % oxygen : 90 % nitrogen when the time interval between doses was 11 min , instead of the usual 5 minutes.6 control of ph by infusion of sodium bicarbonate did not protect the dogs from the combined effects of hypoxia and repeated isoprenaline challenge.7 after a 60 min period of continuous isoprenaline infusion in dogs breathing room air , only one of 10 dogs survived artificial respiration with 10 % oxygen : 90 % nitrogen and repeated challenge with intravenous isoprenaline ( 1.0 mug/kg ) at 5 min intervals .
