Positive pressure ventilation
 Ventilation of the lungs
 single most important and most effective step in
cardiopulmonary resuscitation of the
compromised newborn
A good resuscitation bag
 Size 200-750 ml
 Capable of avoiding excessive pressure
 A pressure pop-off valve and/or a pressure gauge
manometer
 Capable of giving 100% oxygen
 Appropriate sized mask
Resuscitation bags
 Two types
 Flow inflating bag (anesthesia bag)
 Self inflating bag
Flow inflating bag
Flow inflating bag
 Fill only when oxygen from a compressed
source flows into them
 Depend on a compressed gas source
 Must have a tight face-mask seal to inflate
 Use a flow-control valve to regulate pressure-
inflation
Flow inflating bag will not work
if
 The mask is not properly sealed over the
newborn’s nose and mouth
 There is a tear in the bag
 The flow-control valve is open too wide.
 The pressure gauge is missing
Flow inflating bag
Advantages
 Delivers 100% oxygen at all times
 Easy to determine the adequacy of seal
 “Stiffness” of lungs can be felt
 Can be used to deliver 100% free flow
oxygen
Flow inflating bag
Disadvantages
 Requires a tight seal to remain inflated
 Requires a gas source to inflate
 No safety pop-off valve
 Requires more experience
Self inflating bag
Self inflating bag
 Fill spontaneously after they are squeezed, pulling
oxygen or air into the bag
 Remain inflated at all times
 Can deliver positive-pressure ventilation without a
compressed gas source; user must be certain the
bag is connected to an oxygen source for the
purpose of neonatal resuscitation
 Require attachment of an oxygen reservoir to
deliver 100% oxygen
Without Reservoir
With Reservoir
Self inflating bag
Advantages
 Does not need a gas source to inflate
 Pressure release valve
 Easier to use
Self inflating bag
Disadvantages
 Will inflate even without adequate seal
 Requires a reservoir to deliver 100% oxygen
 Can not be used to deliver 100% free flow
oxygen
Masks
 Cushioned/Non-cushioned
 Round/Anatomical shaped
 Size 0 or 1
Correct position of mask
Testing the self-inflating bag
 Squeeze against your palm
 Pressure felt
 Pressure release valve
 Pressure manometer
 Re-inflation
