Diagnosis of cardiac and respiratory arrest Traclitional methods 1 Carotid pulse check by lay rescuers LoSS of consciousness 3,Pupil dilation 4. Respiratory arrest
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 o Evaluate for signs of circulation in 10 seconds breathing, coughing movement in response to rescue breath
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%0
Assess for a pulse •Time is too longer •Accurate rate 75 % • Sensibitity 90% • Specificity 60%
Rate of false-positive(40%) Results Pulseless Pulse Mista kenly loss the saving opportunity
Rate of false- positive(40%) Results Pulseless Pulse Mistakenly loss the saving opportunity
Rate of false-negative(10 %) Results Pulse Pulseless Unnecessarily do cPr
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
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 with Coma immediately do CPr not clear obstructed airways at first)
The chain of Survival • Early access • Early CPR • Early Defibrillation • Early advanced life support * patient with Coma （ immediately do CPR ， not clear obstructed airways at first）
Basic Life support the first ABCD- o Airway A o Breathing B o Circulation C Defibrillation D
Basic Life Support --- the first ABCD • Airway A • Breathing B • Circulation C • Defibrillation D
