ABSTRACT:
In respiratory care with liquids, the patient is connected to a liquid apparatus and a ventilator for supplying and removing a treatment liquid and a breathing gas respectively to/from the patient. The exchange of gases between the breathing gas and the treatment liquid is improved with a device which causes the breathing gas and/or the liquid to oscillate. The device may be a breathing gas generator which generates different frequencies to cause the breathing gas and treatment liquid to oscillate at appropriate frequencies. The device may be a vibrator unit which is applied to the chest to cause the treatment liquid to oscillate. The device may be a magnetic field generator for generating a magnetic field across the lungs and setting electrically conductive components in the treatment liquid in motion.
