of ventilator are to: provide the patients who are in a deadly danger with respiratory support at their
most dangerous stage; protect patients in going through their dangerous period; ensure a successful
basic treatment for further recovery; provide substitutes for anti-reversion respiratory muscle pathological
changes or anti-reversion upper windpipe injury to maintain the patients’ breathing function; provide
breathing support for patients after sickness or during the recovery period after operation.
a．Gas-driven, electrical control, time-pressure switch, and pressure limit control
b．Have air-oxygen mixer particles of high-performance, can adjust the oxygen concentration
conveniently and accurately.
c．Apply electronic PEEP, can make continuous adjustment of PEEP.
d．PTR has 2 kinds of trigger ways: Pressure trigger and flow trigger.
e. Apply highly and fast sensitive pressure sensor and flow sensor to airway pressure, gas flow detection,
control and display, and has ventilation auto-compensation
f. Many ventilator modes: VCV, PCV. PSV, SIMV. PSIMV（SIMV＋PSV）, CPAP.
g. Apply led, real-time displays these parameters, such as controlling frequency, tidal volume, ventilation,
total breathing frequency, self respiratory rate, compliance, airway resistance, oxygen concentration, it also
displays pressure and curve of flow vale to time.
h. P-V (Pressure-Volume), F-V (Flow-Volume).
i. When the ventilator runs abnormally or is incorrectly operated, it will trigger both audio and visual alarms
to protect itself.
j. even if the power is off, no chokes will occur to the patients, for the respiration tubes are connected to the
outer atmosphere.
