[Regional pulmonary ventilation in patients with ischemic heart disease]. / Regionarnaia ventiliatsiia legkikh u bol'nykh ishemicheskoi bolezn'iu serdtsa.

The state of regional pulmonary ventilation was studied in 41 patients with coronary heart disease (CHD) of various degrees of myocardial affection using pulmophonography. A total degree of ventilation irregularity in the CHD patients did not differ from that of healthy individuals. An increase in this index was noted for the right lung in all the patients. The most noticeable changes of regional pulmonary ventilation were observed in patients with macrofocal cardiosclerosis and consequent cardiac aneurysm, and were expressed in an increase in ventilation of the right lung upper zone and its decrease in the left lung upper zone and in the middle zone of both lungs.

[Effect of hyperbaric oxygenation on pulmonary function, acid-base state and the blood gas composition in mitral heart defect patients]. / Vliianie giperbaricheskoi oksigenatsii na funktsiiu legkikh, kislotno-shchelochnoe sostoianie i gazovyi sostav krovi u bol'nykh mitral'nym porokom serdtsa.

Improvement of external respiration, acid-base balance and gas composition of blood was noted after application of a complex of therapeutic measures in combination with hyperbaric oxygenation. The fact that positive changes in external respiration were less pronounced in patients with stenosis of the left venous orifice than in those with mitral incompetence may evidently be explained by the presence of long-term and high pulmonary hypertension and certain increase in the volume of blood in pulmonary circulation in noncorrected stenosis of the left venous orifice. A decrease in metabolic acidosis is noted, which is a complication leading to deterioration of systemic and peripheral hemodynamics, inhibition and myocardial function and blood supply to the brain.
