2 Introduction Basic Life Support needed for patient whose breathing or heart has stopped Ventilations are given to oxygenate blood when breathing is inadequate or has stopped     If heart has stopped, chest compressions are given to circulate blood to vital organs Ventilation combined with chest compressions is called cardiopulmonary resuscitation (CPR) CPR is commonly given to patients in cardiac arrest as a result of heart attack

3 CPR Saves Lives CPR and defibrillation within 3-5 minutes can save over 50% of cardiac arrest victims CPR followed by AED saves thousands of lives each year In most cases CPR helps keep victim alive until EMS or AED arrives

4 Circulatory System Circulatory system consists of heart, blood, and blood vessels. Transports blood to lungs Delivers carbon dioxide and picks up oxygen Transports oxygen and nutrients to all parts of body Helps regulate body temperature Helps maintain body’s fluid balance

5 Anatomy of the Heart

6 Coronary Arteries

7 Major Arteries

8 Circulatory System Emergencies
Any condition that affects respiration reduces ability to deliver oxygen Severe bleeding Shock Stroke Heart conditions

9 Cardiac Arrest Heart may stop (cardiac arrest) as a result of heart attack Brain damage begins minutes after cardiac arrest Brain damage becomes irreversible in minutes Dysrhythmia, an abnormal heartbeat, may also reduce heart’s pumping effectiveness

10 Causes of Cardiac Arrest
Heart attack Drowning Suffocation Stroke Allergic reaction Diabetic emergency Prolonged seizures Drug overdose Electric shock Certain injuries

11 Chain of Survival Early Access Early CPR Early Defibrillation
Early Advanced Care

12 Cardiopulmonary Resuscitation (CPR)
CPR helps keep patient alive by circulating some oxygenated blood to vital organs Ventilations move oxygen into lungs where it is picked up by blood Compressions on sternum increase pressure inside chest, moving some blood to brain/other tissues

13 Blood circulation resulting from chest compressions are not as strong as circulation from heartbeat
Can help keep brain/other tissues alive until normal heart rhythm restored Often electric shock from AED is needed to restore a heartbeat—and CPR can keep patient viable until then

14 CPR effective only for a short time
CPR should be started as soon as possible In some instances, the heart may start again spontaneously with CPR

15 Overview of Initial BLS Steps
Assess the victim for response and look for normal or abnormal breathing. If there is no response and no breathing, or no normal breathing (i.e. only gasping), shout for help. If you are alone, activate the emergency response system and get an AED (or defibrillator) if available and return to the victim.

16 3. Check the victim’s pulse (take at least 5 seconds but no more than 10 seconds).
4. If you do not definitely feel a pulse within 10 seconds, perform 5 cycles of compressions and breaths (30:2 ratio), starting with compressions (C-A-B sequence)

17 CPR Sequence Check the scene Check for response Call for help
Open the airway using the head tilt/chin lift Give two breaths Check for pulse (carotid) 5-10 seconds Give 30 chest compressions Continue cycle 30 chest compressions/ 2 breaths at a rate of 100 per minute

18 Chest Compressions Alert
Be careful with your hand position For adults/children, keep your fingers off patient’s chest Do not give compressions over bottom tip of breastbone When compressing, keep elbows straight and hands in contact with patient’s chest at all times Compress chest hard and fast, but let chest recoil completely between compressions. Minimize amount of time used giving ventilations between sets of compressions.

19 CPR Review

20 What is the rate for performing chest compressions for a victim of any age?
100 per minute

21 Describe a way you can allow the chest to recoil completely after each chest compression.
Allow the chest to expand completely between each compression.

22 After you open the airway and pinch the nose of an unresponsive adult or child, what is the best way to give mouth-to-mouth breaths? Seal your mouth over the victims mouth and give 2 breaths, watching for the chest to rise

23 What is the best way for a rescuer to know that a rescue breath is effective?
The chest will rise with each breath.

24 You must check adequate breathing before giving breaths to an unresponsive adult victim.  You do this by looking for chest rise and feeling for airflow through the victim's nose or mouth.  What other sign should you assess? Listen for airflow from the victim’s nose or mouth

25 When you do not suspect a cervical spine injury, what is the best way to open an unresponsive victim's airway? The head tilt / chin lift technique

26 What should be the next step when you find an unresponsive victim who has agonal gasps and you have sent someone to activate the emergency response system? Open the airway and give 2 breaths

27 How do you know when to start cycles of chest compressions with breaths for an adult?
The victims is unresponsive, is not breathing, and does not have a pulse.

28 Why it is important to give early defibrillation to an adult?
The most effective treatment for sudden cardiac arrest is synchronized cardioversion

29 What are the steps common to the operation of all AED's in the correct order?
Power on, attach pads, clear & analyze, clear & deliver shock if advised

30 After you power on an AED and attach the pads to the victim, what is the next step you should do?
Clear the victim so the AED can analyze the heart rhythm

31 What might happen if you touch the victim while the AED is delivering a shock?
The AED could shock you while it is shocking the victim.

32 You are using an AED on an adult victim, and the AED gives a "no shock indicated" (or "no shock advised") message.  Until advanced care personnel arrive, what should you do next? Leave the pads in place and continue CPR

33 What is the best way to relieve severe choking in a responsive adult?
Perform abdominal thrusts

34 A choking adult becomes unresponsive while you are doing abdominal thrusts for severe choking.  You ease the victim to the floor and send someone to activate your emergency response system.  What should you do next? Begin CPR, when you open the airway, look for and remove the object if seen, before giving breaths

35 Which of the following statements best describes why you should minimize interruptions when giving chest compressions to any victim of cardiac arrest? If you minimize interruptions, you increase the victims chance of survival.

36 Breathing stops but the heart still continues for 2-3 minutes
Breathing stops but the heart still continues for 2-3 minutes.  What is this called? Respiratory arrest.

37 You find a victim lying on his right side
You find a victim lying on his right side.  He is not breathing but has a pulse.  What should you do? Give a rescue breath every 5 seconds.

38 What happens during a cardiac arrest?
The heart and breathing stop without warning.

39 Before starting chest compressions, you need to check for a pulse
Before starting chest compressions, you need to check for a pulse.  What pulse site should you use? Carotid

40 A person shows signs of circulation after CPR was started
A person shows signs of circulation after CPR was started.  What should you do? Place the victim in the recovery position, lying on their side.

41 The purpose of the recovery position is to:
Prevent aspiration.
