Diagnosis of cardiac and respiratory arrest Raditional 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 Elmination of the pulse check for lay rescuers 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 75o Sensibitity 90 Specificity 60
Assess for a pulse •Time is too longer •Accurate rate 75 % • Sensibitity 90% • Specificity 60%
Rate of false- positive(40%0) Results Pulseless Pulse Mista kenly loss the saving opportunit
Rate of false- positive(40%) Results Pulseless Pulse Mistakenly loss the saving opportunity
Rate of false-negative (10 %o) 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 o Early access Early CPr Early Defibrillation Early advanced life support x 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 Breathing B o Circulation C ° Defibrillation D
Basic Life Support --- the first ABCD • Airway A • Breathing B • Circulation C • Defibrillation D
△ Tray Tilt the head backwards o Liit the jaw Open the mouth Clearing obstructed airways from choking Subdiaphragmatic abdominal thrust (Heimlich maneuver)
Airway • Tilt the head backwards • Lift the jaw • Open the mouth • Clearing obstructed airways from choking • Subdiaphragmatic abdominal thrust (Heimlich maneuver)
