Abstract: | Diurnal fluctuations of acid-alkaline balance and blood gas composition were studied in March on 20 healthy males aged 20-26. Using cosinor analysis, mesors, amplitudes and acrophases were revealed. Calculated acrophases (in h and min) are as follows: pH--16 h 05 min, standard hydrogen carbonate--18 h 45 min, actual hydrogen carbonate--22 h 55 min, buffer bases--19 h 03 min, pCO2--2 h 47 min, pO2--4 h 39 min, HbO2--8 h 07 min, hemoglobin--14 h 16 min. All the values studied during diurnal cycle correlated, forming certain circadian rhythms. |
