FIELD: medicine.
SUBSTANCE: oral load of 10% potassium chloride 0.55 mm per kg of body weight by pressure chamber immersion at a depth of 60 meters and staying there for 1.5 hours is followed by calculating a kaliuretic renal activity index (KRAI) by formula: KRAI=0.2·K1-0.1·H1-0.2·D2-0.2·K2+0.2·K3+0.1·X, wherein: K1 is renal potassium excretion 40 minutes after the water load, mmole/h; H1 is sodium excretion 60 minutes after the water load, ml/min; D2 is diuresis 60 minutes after the water load, ml/min; K3 is renal potassium excretion 60 minutes after the water load, mmole/h; K3 is renal potassium excretion 90 minutes after the water load, mmole/h; X is chloride excretion 90 minutes after the water load, mmole/h; if the derived value is less than 0, the kaliuretic renal function is considered to be inadequate; the value falling within the range of 0 through 1.0 shows the adequate kaliuretic renal function, while the value of 0.1 and more makes the good function be stated.
EFFECT: more accurate estimation of the human kaliuretic renal function in high pressure gas medium by comparing the clinical findings.
