APPENDIX C
MTV-100 Manually Triggered Ventilator (Optional)
The MTV-100 Manually Triggered Ventilator is an oxygen-powered breathing device which
complies with the Australian Standard for ‘Resuscitators intended for use with humans’ AS 2488-
1995. It is designed to deliver 100% oxygen to a breathing or non- breathing casualty. It is fitted
with a self-store hose assembly that is
connected to the self- seal valve of the
KDK85 Autovalve
by the diameter-indexed oxygen handwheel. The appropriate size facemask (provided) is attached
directly to the MTV (alternatively, the CPR-PRO Resuscitation Mask can be attached to the
MTV). With a good face seal, up to 100 % inspired oxygen is provided to a breathing or non-
breathing patient.
In non-breathing patients, hold the MTV-100 Manually Triggered Ventilator and face mask in
place and depress the manual control button until the patient’s chest gently rises. Then release the
button and allow the patient to exhale. Repeat this cycle about 12-14 times per minute for an adult
and 20 times per minute for a child. If the patient begins to breathe spontaneously and triggers the
MTV, maintain the mask seal and the flow of oxygen, but do not depress the manual control
button. The patient will continue to receive up to 100% oxygen.
Note: If the airway is obstructed the MTV will stall. Clear the patient’s airway and retry.
In breathing patients, inspiration triggers the MTV which provides flow rates up to
100 L/min. However the patient must be breathing sufficiently (as with any demand valve), to
create a small negative inhalation pressure (-1 to -2.5 cm H
2
O) to initiate oxygen flow. If the
patient is breathing too rapidly or weakly to open the valve effectively, the operator must
manually operate the MTV-100.
