High-frequency jet ventilator

Paravent is a high frequency jet ventilator designed for the short term use
for urgent medicine, including the possibility to ventilate in conventional frequencies.
It’s well appropriated for urgent and critical care applications and transportation
as well as other uses in specific medicial areas. This unique technology,
originated in former Czechoslovakia, won three gold, worldknown, awards (Japan,
Netherlands, Czech Republic).
High Frequency Lung Ventilation
HFV is artificial lung ventilation where supra-physiologic frequencies of ventilation
cycles are being used (frequencies exceeding 60 – 80 cycles/min; in compare,
spontaneous breathing frequencies are 10 – 40 breaths/min in adults and up to
60/min in small children)
divided into several groups (according to frequencies and type of technology):
1. HFPPV (High frequency positive pressure ventilation), freq. from 60 to 200 b/
min.
2. HFJV (High frequency jet ventilation), freq. applied: 80 – 600 b/min
3. HFO (High frequency oscillation), freq. exceeding 600 b/min.
