[Changes in respiration and blood circulation during the inhalation of air mixtures with lethal and sublethal concentrations of hydrogen sulfide-containing natural gas].
Experiments in pentobarbital-anesthetized cats of both sexes showed that upon spontaneous inhalation of hydrogen sulphide-containing gas mixtures (600 mg/m3) respiratory and circulatory changes occur within 10-15 min (30% of animals) and continued to 20-25 min (100% of animals) leading to severe respiratory disturbances (apneusis, gasping) abrupt decrease of mean systemic arterial pressure and decreased cardiac output, i.e., the changes of the type of peripheral collapse.
