[Acid-base state in rats with different resistance to hypoxia in experimental tracheal stenosis]. / Kislotno-osnovnoe sostoianie u krys s razlichnoi rezistentnost'iu k gipoksii pri éksperimental'nom stenoze trakhei.

Rats with different resistance to hypoxic hypoxia differ in parameters of their acid-base state: in high resistance, lower values for blood pH are recordable together with slightly higher pCO2 and content of non-volatile acids. Development of experimental stenosis of trachea in low- and high-resistant animals has been shown to significantly disturb the acid-base state (particularly in low-resistant rats). This process is compensatory-adaptive; it is characterized by development of respiratory acidosis at day 1 to 3, with the indices tending to return to the normal range at day 7, mixed acidosis developing later on.
