    OS 213: Human Disease and Treatment 3 (Circulation and Respiration) LEC 35: ADULT BASIC LIFE SUPPORT FOR HEALTH WORKERS

    Exam 1 (MegaExam)| Dr. Paul Reganit | October 9, 2012

    OUTLINE

    INTRODUCTION

    Objectives To increase awareness and knowledge of CPR as a life-saving

    procedure for victims of sudden cardiac arrest To demonstrate the different steps and techniques of CPR

    Burdern of CVS Diseases in the Philippines Heart diseases are the #1 cause of death in the Philippines (DOH

    data as of 2004) Followed by vascular system disease, malignant neoplasm,

    accidents, then pneumonias There has been a change in causes of mortality (initially due to

    infectious diseases) now more due to lifestyle-related causes such as stress an epidemiologic shift

    Shift is thought to be from effective immunizations The middle class bears the double burden of disease o upper 10% of society have already transitioned to non-

    communicable o the poor still at greatest risk for communicable diseases

    Sudden Cardiac Death (SCD): A Health Burden Approximately 50% of deaths from cardiovascular diseases single largest categoric cause of natural death in the US, and

    probably also in the Philippines most common mode of death in patients with coronary artery

    disease

    Sudden Cardiac Arrest an abrupt cessation of cardiac mechanical function which may be

    reversible by a prompt intervention but will lead to death in its absence

    The heart suddenly goes into very irregular fast ineffective contractions, the heart stops beating, the victim loses consciousness, and if untreated, dies.

    It is unpredictable and can happen to anyone, anywhere at anytime

    Risk increases with age (especially individuals 60 years old and above)

    common in people with pre-existing heart disease o but may still strike people with no history of cardiac disease or

    cardiac symptoms Rescue Breathing/CPR: Do what the patient isnt o If not breathing, breathe for her

    If sudden cardiac death occurs outside the hospital setting o cardiopulmonary resuscitation (CPR) must begin within 4-6

    minutes o Advanced cardiac life support measures (ACLS) must begin

    within 8 minutes, to avoid brain death Only 4-6 % of sudden cardiac arrest victims survive because

    majority of those witnessing the arrest do not know how to perform CPR.

    Almost 80% of out-of-hospital cardiac arrests occur at home and are witnessed by a family member.

    Therefore: effective CPR done immediately after cardiac arrest can double a victims chance of survival o prompt recognition of the problem and swift action

    (management) vs Sudden Cardiac Death: sudden irreversible cessation of all

    biologic functions

    CPR AND THE CHAIN OF SURVIVAL THE NEW CHAIN OF SURVIVAL: (MEMORIZE)

    1. Early access (immediate recognition and activation) 2. Early CPR 3. Early defibrillation 4. Early advanced care 5. Integrated post-cardiac arrest care

    First Link: Access A well-informed lay person is THE key in the early access link Recognition of signs of heart attack and respiratory failure Call for help immediately if needed Activate the Emergency Medical System (EMS)

    Early Warning Signs Of Heart Attack Prolonged compressing pain or unusual discomfort in the center

    of the chest Pain may radiate to shoulder, arm, neck or jaw, usually on the left

    side Pain may be accompanied by sweating, nausea, vomiting and

    shortness of breath

    Early Warning Signs Of Respiratory Failure Unable to speak, breathe or cough Clutches neck (universal distress signal) Bluish color of skin and lips

    Second Link: Early CPR Life saving technique for cardiac and respiratory arrest Rescue breathing and chest compressions For lay persons and medical personnel alike

    CARDIOPULMONARY RESUSCITATION (CPR) What is CPR?

    CPR = cardiopulmonary resuscitation Emergency procedure used when someones heart stops beating. Simple procedure that can be learned by anyone, and consists of a

    manual technique using repetitive pressing to the chest and breathing into the person's airways that keeps enough oxygen and blood flowing to the brain

    CPR requires no special medical skills and training is available for the ordinary person nationwide.

    Why Is Early CPR Important? CPR is the best treatment for cardiac arrest until the arrival of an

    automated external defibrillator (AED) and advanced cardiovascular (ACLS) care

    Prevents ventricular fibrillation from deteriorating into asystole May increase the chance of defibrillation Contributes to the preservation of heart and brain function Significantly improves survival Prompt CPR is important: beyond 7 minutes with no CPR, you are

    doomed to fail

    How Does CPR Work? All the living cells of out body need a steady supply of oxygen to

    keep us alive o Important organs of concern during acute CPR: lungs

    (pulmonary), brain (cerebral), heart (cardiac) o A clarification regarding the importance of adrenals: by giving

    oxygen perfusion to the adrenals, you can reactivate circulation of the catecholamines (Norepinephrine and Epinephrine); but in CPR, your immediate target organ includes the lungs but not necessarily the adrenals

    CPR works because you can breathe air into the victims lungs to provide oxygen into the blood.

    When you press on the chest, you move the oxygen-carrying blood through the body.

    When Will You Do CPR? As soon as possible! Brain cells begin to die after 4-6 minutes without oxygen

    Who May Learn CPR? CPR is an easy and life saving procedure and can be learned by

    anyone One does not need to be a doctor to learn how to do CPR

    TECHNIQUES AND STEPS IN CPR Witnessed Cardiac Arrest

    *sir: Do it to someone youve seen alive and go into cardiac arrest (because you know the type of arrest) **Block B trans: What to do when you find an unconscious person on the ground 1. Check area safety Survey the scene See if the scene is safe to do CPR Get an Idea of what happened

    2. Check Unresponsiveness Tap or gently shake the victim Rescuer shouts: Are you okay? Quick check for normal breathing If the victim is unconscious, rescuer calls for help

    3. Call for Help: ambulance, emergency services, doctor Rescuer activates the emergency medical services Get AED/Defibrillator Non-responsive, no normal breathing = get a defibrillator!

    Check For Consciousness *from Block B trans only, not mentioned in lecture 1. Pulse Check Palpate for carotid pulse within 10 seconds At the same time check for breathing For trained health care providers only!!!

    2. Mouth To Mouth Breathing Begin if there is a DEFINITE PULSE, but NO BREATHING Give one breath every 5-6 seconds (about 12 breaths per minute) Recheck pulse every 2 minutes

    Mouth to Mouth Breathing and Pulse Check: Deemphasized in the new guidelines For trained healthcare providers only As short and quick as possible Pulse check not more than 10 seconds If unsure, proceed directly to chest compressions

    After Determining Unconsiousness

    PROCEED TO C-A-B Compression: Do chest compressions first Airway: does the victim have an open airway (air passage that

    allow the victim to breathe)? Breathing: is the victim breathing

    START CPR (C-A-B)

    COMPRESSION To assist circulation After determining unconsciousness and calling for help, proceed

    immediately to do chest compressions Procedure: 1. Kneel facing the victims chest 2. Place the heel of your hand on the center of the victims chest.

    Put your other hand on top of the first with our fingers interlaced. o Note: Avoid the xiphoid cartilage!

    3. Place the heel of one hand on the sternum in the center of the chest between the nipples then place the heel of the second hand on top of the first so that the hands are overlapped and parallel.

    4. Align shoulders over hands with elbows locked and arms straight. 5. Compress down and release pressure smoothly, keeping hand

    contact with chest at all times.

    Figure 1. Procedure for doing proper chest compression.

    Caveats: (and important things to remember) Give chest compressions at a rate of AT LEAST 100/minute Compress bone at least 2 inches deep Compress 30 times initially (takes around 15-18 seconds) Count aloud 1,2 3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,

    18,19,20,21,22,23,24,25,26,27,28,29, and ONE! Minimize interruptions Allow the chest to return to its normal position Slogan: Push hard, push fast (AHA); Modified by sir to: Push hard,

    push fast to reach your goal you must! (from block B) One may choose which hand to put on chest and which one to put

    over it, but sir uses dominant hand on chest

    AIRWAY Open the airway by using the Head Tilt/Chin Lift Method

    (MEMORIZE) o Place one hand on the victims forehead o Place fingers of the other hand under the bony part of the

    lower jaw near the chin o Tilt head and lift jaw avoid closing the victims mouth o This maneuver prevents airway obstruction by the epiglottis

    If you are highly suspecting cervical spine injury, do Jaw Thrust Method instead (sir: Just lift jaw towards you, dont lift the head)
