The test system with micro processor monitoring control of the incubator operation parameters will be connected to the power source. The monitoring parameters values (temperature against air, temperature against skin, relative humidity, oxygen concentration, neonate mass etc) will be output to the monitor 7 of the control 6 and display unit placed on the incubator. The baby will be placed in the infant module 1. The incubator for the newborn automatically provides the adjustable heat gain, required air humidity and concentration of oxygen in infant module 1, body mass control.
The thermotherapy will be made by means of maintaining the present temperature of air inside infant module 1 of the incubator with adjustment of air temperature of patient's skin temperature, provision with required humidity of air, oxygen therapy by adjusting the air saturation with oxygen, infant module 1 slope adjustment to ensure the low or high position of the head. Standard or intensive care will be made by opening the doors for hands in the windows 16 or lateral doors 18 and 19 of the windows of larger size.
Moreover, when required, the following activities of intensive therapy will be carried out:

blood transfusion,
dosed administration of medical solutions,
aspiration from upper airways,
artificial ventilation of lungs,
phototherapy,
X-ray.

The following parameters are output to the monitor 7:

air temperature,
skin temperature (two sensors),
