Optimal oxygen savings are obtained by connecting the oxygen reser-
voir bag to the resuscitator. The ventilation gas is close to 100% O
when the oxygen supply is equal to or larger than the minute ventila-
tion.

A simplified table is printed on the oxygen reservoir bag for quick ref-
erence. See I. As a minimum, the oxygen concentrations indicated
are obtained 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: Administer 13 l/min oxygen through the inlet of the oxy-
gen reservoir bag. With a tidal volume of max. 1000 ml and a fre-
quency of compression of max. 15 per minute, an adult patient
receives an oxygen concentration of at least 85%.
Administer 2 l/min oxygen through the inlet of the oxygen reservoir
bag. With a tidal volume of max. 300 ml and a frequency of compres-
sion of max. 20 per minute, an child receives an oxygen concentration
of at least 40%.
6. Description
The Ambu Mark IV resuscitator is designed in accordance with the
original Ambu double wall principle.
The standard Ambu Mark IV resuscitator consists of the following
parts: Bag with inlet valve and patient valve.

6.1. Bag - see
9.1: Connector, 9.2: Thin-walled outer cover, 9.3: Self-expanding inner
bag, 9.4: Inlet valve housing (ISO 32 mm connector for connecting the
oxygen reservoir bag as well as the oxygen inlet connector used when
2
the oxygen reservoir bag is not connected), 9.5: Flange lock.
9.9: The bag is supplied with a supporting strap that supports the grip
on the bag during ventilation, and it has an integrated hanging strap,
9.10: The hanging strap has a window with a snap fastener with a
nameplate. The nameplate can be stamped or engraved.
During normal operation of the bag with one hand, the elasticity of
the outer bag will prevent the airway pressure from exceeding approx.
7 kPa (70 cm H
is unique to the Ambu Mark IV resuscitator.
6.2. Patient valve - see
The function of the valve is described in Section 4.
{ 11.1:Splash guard (optional accessory), 11.2 30 mm ISO male
expiration connector for direct connection of Ambu PEEP valve,
11.3: 24 mm inspiration connector (male),
11.4: 22/15 ISO patient connector.
6.3. Oxygen reservoir bag (optional) - see
The oxygen reservoir bag consists of PES/TPU (9.8) connected to a
reservoir housing (9.6) with cap (9.7), which fits the inlet valve connec-
tor on the resuscitator.
The valve has two silicone rubber valve discs that enable intake of
external air when the bag is empty, and discharge of excess oxygen
when the bag is full.
