Rotary HFO IMV ventilator for Infant and Adult

High Frequency Oscillation (HFO) Ventilation permits sufficient and sustained exchange of gas via ventilation of which the stroke volume (tidal volume) is smaller than the volume of anatomical dead space.
HFOV technology has long been established in neonatal field and the following merits are well admitted.
Smaller pressure fluctuation within the thoracic cavity reduces the danger of tracheobronchial injury.
Smaller pressure fluctuation in the alveoli gives less variation of blood pressure and intracranial pressure.

Rotary HFOV
Newly developed rotary valve alternates air way to the membrane chamber between delivery side (push-in) and suction side (pull-out) of the blower in intervals corresponding to the Hz setting and thus generates powerful oscillation of the circuit pressure.

Easy HFO Setting
The actual pressure amplitude is shown in an indicator window that enables easy setting of the stroke volume. Stroke volume values are an index of tidal volume (Vt). Since Vt varies with the oscillation cycle (Hz), the stroke volume indicator changes automatically when the Hz setting is changed. Mean airway pressure (MAP) is controlled independent of the Hz and stroke volume.

Not only HFOV but also many IMV modes, full support to weaning, are available
By selecting not only HFOV but also various IMV modes (PCV, VCV, PSV, CPAP), the R100 can smoothly cope with changes in condition of the patient. Flow trigger and pressure trigger are selectable. By setting the proper trigger levels, the R100 can quickly respond to and support various levels of breathing effort of the patient.

Three modes, one touch selection
Ventilatory modes can be changed merely by turning the selector switch.

Manual sigh functionality
A manual sigh can be applied by pushing the "Manual Sigh" button. Manual sigh gives one breath in IMV. In HFOV, sustained inflation is performed during the time the "Manual Sigh" button is being pushed.

High performance ventilation is realized by newly developed high performance valves
Newly developed valves realized quick and accurate flow control required for high performance IMV. Due to such high performance valves together with excellent electrical hardware and software, the R100 can quickly detect and respond to respiratory requests of patients.

R100 Design for Safety and Security
Diaphragm Chamber
The chamber generates pressure oscillation in the patient circuit by oscillation of the pressure on the machine side of the membrane. The chamber insulates the inside and the outside of the machine. The chamber is easily removed from the machine after one patient use.
Exhalation Filter
To prevent air pollution by exhaust gas from the ventilator, exhalation gas is passed through a bacteria filter installed on the wall of the ventilator.
Blower Filter
During HFO operation, very large flow volumes and speeds are generated. To prevent airborne dust from entering the air stream, a large blower filter is installed. The filter can be changed in between sessions.
Automatic setting of airway pressure alarms
Alarms related to the airway pressure are automatically preset around operation pressure settings. Low and high amplitude alarms are also automatically set. Margins of alarm settings against pressure settings aor gainst actual amplitude data can be preset in the LCD screen.

Monitoring
A graphic LCD monitor is available. The monitor shows pressure, flow and volume patterns in IMV operation.
