The
priority of the Russian school of ozonetherapy is the wide use of intravenous
drop-by-drop infusions of ozonated physiological saline – a simple and effective
method of parenteral exposure of medical ozone.

It is important to note that this method allows to receive positive
therapeutical effects in different medical problems by using
considerably lower, i.e. more safe ozone concentrations compared with
ozone concentrations accepted by the European school of ozonetherapy.

Ozonated physiological saline is produced by conveying ozone-oxygen mixture
through a standard bottle with 200 or 400 ml of sterile physiological 0,9%
sodium chlorid solution to saturation and then infused intravenously to the
patient (Fig. 1).
This procedure can be performed in two variations – after interrupting bubbling
with ozone for the time of intravenous infusion of solution (Fig. 2) and by
infusing solution during continual
bubbling with ozone (Fig. 3). Mark of zero on the axis shows the beginning point
of intravenous infusion of ozonated saline.

In both
the cases, before infusion saline should be previuosly bubbled with ozone to
saturation (saturation – mark of 100% of dissolved ozone, see Fig. 2, 3).
Saturation of solution with ozone concentration in gas mixture 400 - 2000 mcg/L
can be achieved for 10-15 min at flow rate 1 L/min and for 15-20 at flow rate
0,5 L/min. Further bubbling results in an insignificant increase in the amount
of ozone dissolved in the physiological saline (formation of additional active
species of oxygen) that can be disregarded.
Calculation of the Dose
Considering that the concentration of ozone dissolved in the physiological
saline is approx. 20% of the given ozone concentration in gas mixture i.e.
dissolution coefficient is 0,2, that means that for example at ozone
concentration in gas mixture 1000 mcg/L in 1 L of physiological saline the
following amount of ozone will be dissolved: 0,2 x 1000 = 200 mcg O3
(calculation error not more than 10%).
In case of infusing an ozonated physiological saline by continuous bubbling,
saturation of saline remains practically constant all the time of procedure
(Fig. 3, area II). The dose of ozone infused to the patient is calculated as
follows:
Dose (mcg) = 0,2 x concentration O3 (mcg/L) x volume of saline (L)
For example, at ozone concentration in gas mixture 1500 mcg/L and volume of
saline bubbled with ozone 400 ml the dose of ozone infused the patient during
the procedure = 0,2 x 1500 x 0,4 = 120 mcg O3. During the procedure
after interrupring bubbling with ozone for the time of intravenous infusion of
ozone it is important to know that decomposition of ozone after stopping
bubbling is described by complex exponential function, the half-life of ozone is
approx. 30 minutes (Fig. 2, area II). The total dose of ozone infused to the
patient within treatment time of 30 min is 67% of the dose calculated for the
procedure by continuous bubbling (calculation error not more than 10%):
Dose (mcg) = 0,67 x 0,2 x
concentration O3 (mcg/L) x volume of saline (L)
For example, at ozone concentration in gas mixture 1500 mcg/L and volume of
saline bubbled with ozone the dose of ozone infused to the patient during the
procedure = 0,67 x 0,2 x 1500 x 0,4 = 80,4 mcg/ O3.
