Check that inflation and expiration occur without obstruction.
Usually it is not necessary to disassemble the valve immediately
for cleaning.
If the valve is disassembled and cleaned, be sure to perform a
pre-operation test before continuing ventilation. (See section 8.1)
Administer oxygen according to medical indications.
See section 5.2 to 5.4.
5.2. Oxygen administration without reservoir
– see
T
Supplementary oxygen can be administered by connecting the
O2nipple on the inlet valve to an oxygen flow meter.
Examples of O2percentages, which can be obtained with
different volumes and frequencies, can be seen in Y.
VT: Ventilation volume, f: Frequency
5.3. Oxygen administration with reservoir bag
attachment – see
U
By connecting the oxygen reservoir bag attachment, optimal
oxygen economy is obtained, and the ventilation gas will be
100 % O2when the oxygen flow is equal to or greater than the
minute ventilation.
U7.1: Filled, 7.2: Empty
Examples of O2percentages, which can be obtained with
different volumes and frequencies, can be seen in I.
VT: Ventilation volume, f: Frequency
These values correspond to the theoretically possible, i.e.
higher O2concentrations cannot be reached.
For quick reference a simplified chart is printed on the reservoir
bag. See O. The indicated oxygen concentrations will be
obtained and exceeded as long as the minute ventilation is
equal to or less than 1000 x 15 = 15 l/min. and 300 x 20 =
6 l/min., respectively.
Examples
Introduce an oxygen flow at 13 l/min. into the inlet of the reservoir
bag attachment. With a ventilation volume of max. 1000 ml and
a compression frequency of max. 15 per minute, an adult will
receive an oxygen concentration of no less than 85 %.
Introduce an oxygen flow at 2 l/min. into the inlet of the reservoir
bag attachment. With a ventilation volume of max. 300 ml and
a compression frequency of max. 20 per minute, a child will
receive an oxygen concentration of no less than 40 %.
5.4. Oxygen administration with gas filter adapter
and protective mask filter – see
P
Examples of O2percentages, which can be obtained with
different volumes and frequencies and with a gas filter attached
to the resuscitator, can be seen in {.
VT: Ventilation volume, f: Frequency
6. Description
The basic Ambu Mark III resuscitator consists of the following
parts: Bag with inlet valve and patient valve.
Masks, oxygen reservoir bag attachment, gas filter adapter
and PEEP valve are accessories, which make the Mark III
resuscitator a most versatile resuscitation unit.
