Sechenov and His Works on the Blood Gases
I. M. Sechenov was a prominent Russian scientist, the founder of Russian physiology and scientific psychology.
The range of Sechenov’s scientific interests and the number of his research works are really great. 106 scientific works were written by him. In these works he included the findings which he had observed and determined before.
Some of his research works were connected with the investigation of the blood gases and their role in the respiratory process.
I. M. Sechenov isolated the blood gases and found out that most of the blood gases were combined with erythrocytes. No physiologist had been able to do it before Sechenov. On the basis of his observations I. M. Sechenov came to the conclusion that hemoglobin was that substance of the blood which accomplished the exchange of oxygen and carbon dioxide in the respiratory process. Physiologists of many countries who had worked on this problem before Sechenov could not estimate the role of hemoglobin in the act of respiration. So the accomplishment of the respiratory process is due to hemoglobin.
I. M. Sechenov investigated the process of absorption of carbon dioxide by the solutions of salts. When he had completed his investigations, he proved that only 2/3 of carbon dioxide were dissolved in plasma. The rest of carbon dioxide was combined with red blood cells. The transfer of carbon dioxide from the blood into the lungs was due to the law of diffusion of gas from fluid into the air. When Sechenov had investigated this phenomenon, he was able to answer the question why oxygen passed into the blood from atmospheric gases during the act of respiration.

The Physiology of the Lungs
The physiology of the lungs is associated with their structure. There are over 700,000,000 alveoli in the lungs. The total surface of the alveoli is about 90 sq. m (square metres). The lungs have many capillaries with the total surface of about 80 sq. m. This particular structure of the lungs enables the exchange of gases between the alveolar air and the blood.
Elastic fibers of connective tissue composing the walls of the alveoli, alveolar passages and the visceral pleura enable the lungs to dilate. When one breathes normally not all the alveoli and capillaries of the lungs are opened. When respiration becomes deep, the number of the opened alveoli and capillaries increase. The flow of blood into the lungs increases when one breathes in and it decreases when one breathes out.
The regulation of the vital capacity of the lungs is of particular importance to the exchange of oxygen and carbon dioxide taking place in the lungs. It is considered that in the adult the vital capacity may be 6 litres and even more.
The lungs take part in the production of physiologically active substances, in the regulation of blood coagulation, in the metabolism of proteins, fats and carbohydrates.

Patient Ivanenko, aged 48, was admitted to the hospital with the diagnosis of lobular pneumonia. He had been developing lobular pneumonia gradually. A week before the admission to the hospital he had bronchitis after which his condition did not improve.
Fever had an irregular course and the temperature changes were caused by the appearance of the new foci of inflammation in the pulmonary tissue. Fever had been persisting for two weeks and had been decreasing gradually.
The patient’s breathing was rapid with 30 – 40 respirations per minute. There was breathlessness and cyanosis of the face associated with the accompanying bronchitis, decrease in the respiratory surface and occlusion of numerous bronchioles and alveoli.
The patient complained of the pain in the chest, particularly on deep breathing in, and cough with purulent sputum. The pulse rate was accelerated and arterial pressure was reduced.
On physical examination dullness in the left lung, abnormal respiration, numerous răles and crepitation were revealed. Dry răles caused by diffuse bronchitis were heard all over the lungs. The liver and spleen were not enlarged. The examination of the organs of the alimentary tract failed to reveal any abnormal signs but the tongue was coated.
The blood analysis revealed leucocytosis in the range of 12,000 to 15,000 per cu mm of blood and an accelerated erythrocyte sedimentation rate (ESR).
The urine contained a small amount of protein and erythrocytes. The X-ray examination of the lungs revealed numerous foci of inflammation of various size, irregular form and different intensity. Shadowing was particularly marked at the root of the left lung due to the enlargement of the lymphatic gland.
It was a severe form of lobular pneumonia which was difficult to differentiate from pulmonary tuberculosis and pleurisy. Yet the physician made a correct diagnosis.
