| Sumario: | The simple and effective method of the leakage test in thoracic surgery using laser photo-acoustic leak detector «LaserGasTest» was suggested and tested in experiment on mongrels. Sulfur hexafluoride used for the work of leak detector is an inert and biologically harmless gas of the 4th class of danger and its concentration in medical ventilation apparatus does not exceed 5000 mg/m3 (0.077 %). The proposed technique provides real-time high-frequency determination of location and size of leakage. |
