Ventilators

Star Infrasonic

Draeger Evita 4

Star Infrasonic ventilator

Classification:

· microprocessor controlled electronic ventilator

· multiple weaning modes

· three power sources (Gas, electrical, internal and external battery source)

Modes available:

· volume control (SIMV + PPS, ASSIST CONTROL, CPAP & PPS )

· pressure control Time cycled (SIMV + PPS, ASSIST CONTROL, CPAP & PPS)

· pressure control I:E cycled (SIMV + PPS, ASSIST CONTROL, CPAP & PPS)

· BIPAP

Quick test: Mandatory prior to initiating ventilation

· depress and hold down visual reset and alarm silence buttons while turning the panel ON/OFF switch to ON

· after 5 secs the performance, safety and diagnostic screen will be displayed

· move the cursor to quick test and press enter

· follow prompts (there are fourteen tests that are automatically performed during the quick test; if a test fails, use the cursor to rerun this test, once you’ve rectified the problem)
