CPR is used for patients who cannot breathe on their own. It was later replaced by the Ambubag due to issues like human error and lack of oxygen delivery. The Ambubag was invented in the 1950s and delivers air to patients through a squeezable bag and mask. Ambubags were later replaced by artificial ventilators, which were developed in the 1960s to automatically regulate air flow and monitor patient vital signs like heart rate and oxygen levels. Ventilators use algorithms and conditions to precisely control air delivery and alert doctors to potential issues.

3. CPR(Cardiopulmonary Resuscitation)
What is CPR?
CPR is an acronym,abbreviation or slang word.
It’s use for that patients which can not breathing.

4. How CPR method changed to Ambubag?

5. Con…
Cause of different factors:
 Human Sickness
It Was Very Bore
Less Oxygen to patient
Less Air to patient

6. What is Ambubag?
The bag-valve mask concept was developed in
1953 by the German engineer HOLGER HESSE
and his partner HENNING RUBEN and it was
the first non-electric Ambubag which invented
by them and used up to 1960
it’s made of soft plastic Then they renamed
the valve mask to Latine word Ambu now it’s
known internationally by the name of
Ambubag.

7. Con…
The Ambubag has squeezable bag.
A one way valve.
Face mask.
Compressing bag forcing Air
Through to the mask then to the
lungs.
Ambubag used for those patients
which have not breathing.
Used by DR/Nurses For patients

8. How Ambubag is changed to Ventlator?

9. Cont…
 Nitrogen
 Standardize
 It was bore for doctors
 Air filtarization
 Pure Oxygen
 Expiration and Inspiration
 Don’t shown patient vital sign

10. Cont…
Patient vital sign:
HR
BP
Spo2(Oxygen rate on the blood).
Patient weight
TEMP.
Lungs input and output air capacity

11. What is an Artificial Ventlator?
Is a mechanical ventilator ‘ a machine
designed to move breathable air into
and out of the lungs to provide
breathing for a patient who is
physically unable to breathe or
breathing insufficiently
• Idea by JOHN HAVoN EMERSON at
1960 then it’s developed by him self
at 1963

12. Cont…
Essential components in mechanical ventilation
Patient
Artificial airway
Ventilator circuit
AC/DC power source
(Battery 12v/9Amp)
Oxygen Supply

13. Cont…
 Engineers Used more then 1000
Algorithms.
 For every function used different
(if………then condition).
EX: IF the patient HR is coming down
50/PerM automatically buzzer is turned on.
EX: IF Patient circuit is disconnected.
EX: IF Oxygen balloon is empty
EX: When patient is die

15. Cont…
 Patient age
 Inspiration and expiration

2-Co2
 HR
 Blood
 Temp
