1. Study Unit 5 Cardiopulmonary Resusitation
EMS I A
Study Unit 5
Cardiopulmonary Resusitation

2. Unit Outcomes
Identify the importance of early, appropriate interventions that lead to optimizing patient survival.
Perform prompt, high quality chest compressions for adult, child & infant victims.
Discuss the role & effectiveness of early defibrillation.

3. Cardiopulmonary Resuscitation
Definition:
Cardiopulmonary resuscitation (CPR) is a procedure to support and maintain breathing and circulation for a person who has stopped breathing (respiratory arrest) and/or whose heart has stopped (cardiac arrest).
Comprises of?
2 ventilations : 30 compressions
At least 5 – 6 cm depth for compressions at a rate of /min

4. Cardiopulmonary Resuscitation
What are we focusing on?
CPP > 15mmHg
Few interruptions
Interruptions < 10 seconds
Coronary perfusion pressure (CPP)

5. CPP Coronary perfusion pressure.
This is the perfusion of coronary vessels.
Occurring during diastole.
Definition: CPP is the difference between the aortic diastolic pressure and the left ventricular end diastolic pressure.
Normal: mmHg
Relaxation = diastole
During CPR we aim to keep a CPP > 15mmHg (drops with every interruption. Therefore interruptions < 10seconds)

6. Myocardial tissue
Myocardial tissue has the highest oxygen consumption per tissue mass.
Oxygen extraction is 70 – 80%.
Normal tissue is 25%

7. Outcome Based CPR High Quality CPR Few interruptions Early CPR
Early defibrillation
Good chest rise with high flow O2
Goal based post cardiac arrest care
