Diagnosis of cardiac and respiratory arrest
Traditional methods :
1. Carotid pulse check by lay rescuers
2. Loss of consciousness
3. Pupil dilation
4. Respiratory arrest
Guideline 2000
Elimination of the pulse check for lay rescuers
Evaluate for signs of circulation in 10 seconds
breathing , coughing , movement in
response to
rescue breath
Assess for a pulse
Time is too longer
Accurate rate 75 %
Sensibitity 90%
Specificity 60%
Rate of false- positive(40%)
Results
Pulseless Pulse
Mistakenly loss the saving opportunity
Rate of false-negative (10 %)
Results
Pulse Pulseless
Unnecessarily do CPR
Electrocardiogram changes of Cardiac arrest
Ventricular fibrillation
A flat line or only atrial wave
Pulseless Electrical Activity, PEA
The chain of Survival
Early access
Early CPR
Early Defibrillation
Early advanced life support
* patient a ( immediately do CPR ,
not clear obstructed airways at first)
Basic Life Support --- the first ABCD
Airway A
Breathing B
Circulation C
Defibrillation D
Airway
Tilt the head backwards
Lift the jaw
Open the mouth
Clearing obstructed airways from choking
Subdiaphragmatic abdominal thrust (Heimlich maneuver)
