Positive pressure ventilation
Ventilation of the lungs single most important and most effective step in
cardiopulmonary resuscitation of the compromised newborn
![Page 3: Positive pressure ventilation Ventilation of the lungs single most important and most effective step in cardiopulmonary resuscitation of the compromised.](https://reader036.fdocuments.in/reader036/viewer/2022070308/551c32f8550346a84f8b6450/html5/thumbnails/3.jpg)
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
![Page 4: Positive pressure ventilation Ventilation of the lungs single most important and most effective step in cardiopulmonary resuscitation of the compromised.](https://reader036.fdocuments.in/reader036/viewer/2022070308/551c32f8550346a84f8b6450/html5/thumbnails/4.jpg)
Resuscitation bags
Two types Flow inflating bag (anesthesia bag) Self inflating bag

Flow inflating bag
![Page 6: Positive pressure ventilation Ventilation of the lungs single most important and most effective step in cardiopulmonary resuscitation of the compromised.](https://reader036.fdocuments.in/reader036/viewer/2022070308/551c32f8550346a84f8b6450/html5/thumbnails/6.jpg)
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
![Page 7: Positive pressure ventilation Ventilation of the lungs single most important and most effective step in cardiopulmonary resuscitation of the compromised.](https://reader036.fdocuments.in/reader036/viewer/2022070308/551c32f8550346a84f8b6450/html5/thumbnails/7.jpg)
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 bagAdvantages
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
![Page 9: Positive pressure ventilation Ventilation of the lungs single most important and most effective step in cardiopulmonary resuscitation of the compromised.](https://reader036.fdocuments.in/reader036/viewer/2022070308/551c32f8550346a84f8b6450/html5/thumbnails/9.jpg)
Flow inflating bagDisadvantages
Requires a tight seal to remain inflated Requires a gas source to inflate No safety pop-off valve Requires more experience

Self inflating bag
![Page 11: Positive pressure ventilation Ventilation of the lungs single most important and most effective step in cardiopulmonary resuscitation of the compromised.](https://reader036.fdocuments.in/reader036/viewer/2022070308/551c32f8550346a84f8b6450/html5/thumbnails/11.jpg)
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
![Page 12: Positive pressure ventilation Ventilation of the lungs single most important and most effective step in cardiopulmonary resuscitation of the compromised.](https://reader036.fdocuments.in/reader036/viewer/2022070308/551c32f8550346a84f8b6450/html5/thumbnails/12.jpg)
Without Reservoir

With Reservoir
![Page 14: Positive pressure ventilation Ventilation of the lungs single most important and most effective step in cardiopulmonary resuscitation of the compromised.](https://reader036.fdocuments.in/reader036/viewer/2022070308/551c32f8550346a84f8b6450/html5/thumbnails/14.jpg)
Self inflating bagAdvantages
Does not need a gas source to inflate Pressure release valve Easier to use
![Page 15: Positive pressure ventilation Ventilation of the lungs single most important and most effective step in cardiopulmonary resuscitation of the compromised.](https://reader036.fdocuments.in/reader036/viewer/2022070308/551c32f8550346a84f8b6450/html5/thumbnails/15.jpg)
Self inflating bagDisadvantages
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
