The document summarizes information about a reservoir bag, also known as an AMBU bag, which is a handheld device used to provide positive pressure ventilation to patients who are not breathing or breathing inadequately. It was discovered in 1953 by a German engineer and anesthesiologist. The bag consists of a compressible self-refilling ventilation bag connected to a mask or airway adjuncts via tubing. When used properly with two rescuers, one to hold the mask and one to squeeze the bag, it can provide room air ventilation or oxygen-enriched ventilation to critically ill patients needing respiratory support during transfer or procedures. Potential complications include lung overinflation or aspiration if not used correctly.

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

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.

SUPPLIED BY BVM UNIT ???
-BVM not connected to oxygen
and reservoir (Room Air)
-BVM connected to oxygen
source of 5 – 10 L
-40 – 60 %
100 %
-BVM with reservoir and 15 L of
oxygen concentration

13. -Reported Complications
--Gastric Insufflation (Vomiting, Aspiration)
--Barotrauma (lung injury from over
pressurization)
--Volutrauma (Lung injury from overstretching)
--Mendelson’s syndrome
--Hypoventilation

14. -How to asses the adequacy
of ventilation
-Observe for chest rise
-Saturation level
-Improving from cyanosis
