5. A hand held device commonly used to
provide positive pressure ventilation to
patients who are not breathing or not
breathing adequately.
using ambu bag to ventilate the
patient is called “ Bagging”.

6. Discovered in the year of 1953
by Dr. Holger Hessee ( a German
Engineer) & his partner Mr.
Henning Ruben ( Anesthestist).
The word “AMBU“ came from “ Ambulance
-HISTORY OF AMBU BAG

7. -Indications
--Respiratory Failure
--Respiratory arrest
--In case of Ventilatory Failure
--Transfer of critical patients between
wards
--In between suctions

8. -Contra Indications
-Paralysis
-Complete upper airway
Obstruction

9. -Airway Adjuncts
-OPA
-NPA

10. 1-Non-rebreathing patient valve
2-Intake valve
3-Compressible self refilling
ventilation bag
4-Nipple for oxygen tubing

11. it is not recommended to use the
AMBU bags when you are a single
rescuer because it is difficult for a
single rescuer to hold the mask and
squeeze the bag at a time, as mouth
& nose should be completely sealed
by mask during bagging. If 2
rescuers there, one can hold the
mask while the other can squeeze
the bag.
