INTRODUCTION: Unexpected cardiopulmonary collapse is a medical emergency that requires immediate institution of the artificial measures to support life and to reverse the initiating pathophysiological event. Cerebral resuscitation is the most important goal of advanced cardiac life support. Resuscitation is a continuous process from basic life support (BLS) to advance cardiac life support (ACLS), where BLS initiates the process and ACLS aims to restore and maintain spontaneous respirations and circulations.
DEFINITION: Cardio pulmonary resuscitation (CPR) is a technique of basic life support for the purpose of oxygenation to the heart, lungs and brain until and unless the appropriate medical treatment can come and restore the normal cardiopulmonary function. Cardio pulmonary resuscitation is a series of steps used to establish artificial ventilation and circulation in the patient who is not breathing and has no pulse.
Historical review: 5000- First artificial mouth to mouth respiration. 3000 BC- Ventilation. 1780-First attempt of newborn resuscitation by blowing. 874- First experimental cardiac massage. 1901- First successful direct cardiac massage in man. 1946- First experimental indirect cardiac massage and defibrillation. 1960- Indirect cardiac massage. 1980- Development of cardio pulmonary resuscitation due to works of peter safar.
HOW CPR WORKS: The air we breathe in, travels to our lungs were oxygenis picked up by our blood and then pumped by the heart to ourtissue and organs. When a person experiences cardiac arrest-whether due to heart failure in adults or the elderly or an injurysuch as near drowning, or severe trauma in a child-the heart goesfrom a normal arrhythmic pattern called ventricular fibrillation, andeventually ceases to beat altogether. This prevents oxygen fromcirculating throughout the body, rapidly killing cells and tissue. Inessence, cardio (heart) pulmonary(lung)resuscitation (revive, revitalize) serves as an artificial heartbeatand an artificial respirator. CPR may not save the victim evenwhen performed properly, but if started within 4 minute of cardiacarrest and defibrillation is provided within 10 minutes, a personhas a 40% chance of survival.
MAIN STAGES OF RESUSCITATION:A (Airway)- ensure open airway by prevention the falling back of tongue, tracheal intubation if possible.B (Breathing) – start artificial ventilation of lung.C (Circulation) – restore the circulation by external cardiac massage.D (Differentiation, drug, defibrillation) – quickly perform differential diagnosis of cardiac arrest; use different medication and electric defibrillation in case of ventricular fibrillation.
CONTRAINDICATIONS Do not resuscitate when a decision notto resuscitate has been noted in chart. This orderis often abbreviated to DNR (do not resuscitate), issometime referred to as no code, and is nowdiscussed with the client on admission and isreferred to as an advanced directive.
ASSESSMENT Determine that the client is unconscious. Shake the client and shout at him or her to confirm if unconscious rather than being asleep, intoxication or hearing impairment. Assess for the presence of respirations. Assess carotid artery for pulse.
EQUIPMENTS A hard flat surface. No additional equipment is necessary but in hospital setting, an emergency (crash) cart with defibrillator and cardiac monitor should be brought to the bedside. A crash cart contains: Airway equipment. Suction equipment. Intravenous equipment. Laboratory tubes and syringes. Pre packed medication for advanced life support.
CAUSES System ReasonsCNS Cerebro-vascular accidents. Shock.Pulmonary: COPD. Airway obstruction. Atelectasis.Cardio vascular: Acute M I. CABG. Heart failure. Dysrhythmias. Heart block.Miscellaneous: Drowning, Fall, Poisoning. Emboli, Accident.
PHASES OF THE CARDIOPULMONARYRESUSCITATION: Phases StepsPhase-1 Basic life support A= Airway B= Breathing C= circulationPhase-2 Advance cardiac life D= Drugs support E= ECG F= fibrillationPhase-3 Prolonged life G= Gauging support H= Human Mentation I= Intensive care
TYPICALLY THE SEQUENCE OF BLSCONSISTS OF ASSESSMENT AND THEABCS OF CPR.AssessmentIt is of crucial importance. It includes Assess responsiveness by calling the person; shouting and shaking. Assess breathing by look, listen and feel: Look for chest movements, listen for breath sounds and feel for the movements of the air flow.
BASIC LIFE SUPPORTAirway management Open and clear the airway: This is achieved by head tilt and chin lift maneuver or if there is suspicion/ evidence of head or neck trauma, the jaw thrust maneuver is used.
HEAD TILT CHIN LIFTMANEUVER: Place one hand on the victim’s hairline and place the other hand’s index finger and the middle finger on the chin and apply firm backward pressure.
JAW THRUST MANEUVER: - It is accomplished by placing one hand on each side of the victim’s head, grasping the angles of the victim’s lower jaw, lifting with both hands.
FINGER-SWEEP MANEUVER:- With the victim’s head up, opens the victim’s mouth by grasping both tongue and the lower jaw between the thumb and fingers and lifting (tongue-jaw lift). This action draws the tongue from the back of the throat and away from the foreign body. The obstruction may be partially relieved by this maneuver.
If the tongue-jaw lift fails to open the mouth then crossed finger technique may be used. This is accomplished by opening the mouth by crossing the index finger and the thumb and pushing the teeth apart. The index finger of the available hand is inserted along the inside of the cheek and deeply into the throat to the base of the tongue. A hooking motion is used to dislodge the foreign body and maneuver it into the mouth for removal.

BREATHING: - After the airwaymanagement if the victim isstill not breathing, thenmaintaining head tilt, chin liftpositions pinch the nostrilsand place the mouth aroundthe victim’s mouth to make atight seal, take two deepbreaths and deliver twopositive pressureventilations; each at least oftwo seconds duration. Whenperforming mouth-to-mouthventilation always assess forchest wall movement.
BAG AND MASKVENTILATION Use a resuscitator bag and mask. Apply the mask to the victim’s mouth and create a seal by pressing the left thumb on the bridge of the nose and the index finger on the chin. Use rest of the fingers of the left hand to pull on the chin and the angle of the mandible to maintain the head in extension.
Use the right hand to inflate the lungs by squeezing the bag to its full volume. Observe the chest wall for symmetric expansion. The volume of air of each ventilation should be approximately 700-1000ml, which can be determined by noting a rise of 1-2 inches in the victim’s chest. Smaller volume (400-600ml) should be attempted during bag and mask ventilation.
CIRCULATION: The carotid artery is used to determine the absence of pulse. While maintaining the head tilt position with one hand on the forehead, locate the victim’s trachea with two or three fingers of the other hand, then slides these fingers into the groove between the trachea and the muscles of the neck where the carotid pulse can be felt. The technique is more easily performed on the side nearest the rescuer. If on assessment, there are no signs of circulation start external cardiac compressions. Position hands, arms and shoulders
External cardiac compressions technique consists of serial rhythmic application of pressure on the lower half of the sternum. The victim is on the horizontal supine position on a flat and hard surface. The rescuer should be positioned closed to the side of the victim’s chest. Locate landmark notch hands in the center of the chest, right between the nipples and four fingers above the xiphoid process.
Elbows should be locked and arms are straight. Rescuer’s shoulders position directly over hands. Begin compression. Pressure should come from the shoulders. Compression should depress victim’s sternum approximately 1.5- 2 inches. Don’t allow the fingers to touch the chest wall. Allow chest to rebound to normal position after each compression.
Perform compression at the rate of 100/min. Maintain correct position at all times. Check for signs of circulation every 3-5 min. Compression: ventilation ratio is 30:2 irrespective of number of rescuer. Exhalation occurs between the two breaths and during the first chest compression of the next cycle. Perform four complete cycles and then reassess for signs of breathing and circulation.
Five keys aspects to greatCPR Rate Depth Release Ventilation Uninterrupted
DEFINETION It is asynchronous cardio-version that is used in emergency situation. Defibrillation completely depolarizes the all myocardial cells at once, allowing the sinus node to recapture its role as the pacemaker.
IMPORTANCE OF EARLYDEFIBRILLATIONS Most frequent arrest frequent arrest rhythm VF/VT Treatment is defibrillation. Successful conversion diminished over time. VF tends to deteriorate to A systole.
DEFIBRILLATION: GENERALCONCEPT Immediate defibrillation ifwitnessed arrest andautomated externaldefibrillation availablecompressions beforedefibrillation if unwitnessed orarrival at the scene >4-5minutes. One shock followedby immediate CPR ( beginningwith chest compression)
KEY POINTS TO REMEMBER WHILE DEFIBRILLATING Use a conducting agent between the skins the paddles such as saline pads or electrode paste. This decreases the electrical impedance and helps to prevent burns. The paddles are placed on the chest wall one the sternal paddle is placed to the right of the sternum, 2’nd intercostals space just below the clavicle. The apex paddle is placed on the left 6’Th intercostals space mid axillary line. Switch on the defibrillator.
Move the knob of the defibrillator to the required amount of joules. Shock at 200,300,360 joules. Exert 20-25 pounds of pressure on each paddle to ensure good skin contact. Press the charge button. Call “stand clear” to ensure that personal are not touching the patient or the bed at the time of discharge. The defibrillator is then discharged by depressing the buttons on the both paddles simultaneously.
GAUGING: Identify the cause of cardiac arrest by: Cardiac monitoring. Lab examination of the blood.HUMAN MENTATION: Start CPR within 4 min as brain can only survive for four min without oxygen. Do not interrupt the CPR more than 7min. Reassess for breathing and circulation every 2-3min.
ECG ECG is the graphical representation of the electrical activity of the cardiac muscles. During CPR the victim’s ECG should be continuously monitored for monitored for monitoring evaluating and recording.
INTENSIVE CARE If the victim’s condition is stable, send the victim to the ICU for close and continuous monitoring.DRUGS THAT CAN BE USED DURING CPR INJ EPINEPHRIN INJ ATROPINE INJ LIDNOCAINE INJ MAGNESIUM SULPHATE INJ DOPAMINE INJ DOBUTAMINE INJ SODA BI CARB INJ CALCIUM GLUCONATE
TERMINATION OF BASICLIFE SUPPORT: CPR is stopped as a result of a number of circumstances; these are typically restoration of spontaneous respiration and circulation, complete rescuer exhaustion, or medical decision. Signs of restored ventilation and circulation include: Struggling movements Improved color Return of or strong pulse Return of systemic blood pressure
NURSING TEAM LEADER(USUALLY SENIOR WARDNURSE) Identifies self as Nursing Team Leader, responsible for co- coordinating and directing emergent nursing care of the patient. Checks appropriate emergency call has been placed Starts timer as soon as the Emergency trolley arrives. Delegates available staff to roles appropriate to their level of practice: Airway, Compression, Monitor & Medications and Runner to collect or remove extra equipment, supplies, labs etc. Establishes the patient’s weight and delegates someone to print out an Emergency Drug Worksheet (Icon on desktop of clinical computers).
Cont ……. Ensures that the patient is placed on CPR back board. Reassigns nursing staff once the PICU nurse and additional staff arrive as required. Ensure someone is assigned to support family members. Documents initial and ongoing vital signs and cardiac rhythm, medication administration, procedures and patient’s response to interventions on the ACH/Starship Resuscitation record (CR8545). Monitors the time interval between adrenaline administration and prompts the Team Leader when 4 minutes has passed since last dose administered. Completes, including a brief summation of presenting events and signs the ACH/Starship Resuscitation record (CR8545). Ensures the outside copy of the CR8545 form is placed on the Charge Nurse desk and the inside copy is placed in the clinical record.
AIRWAY NURSE(USUALLY THE PATIENTS NURSE OR THE NURSE WHO FINDS THE PATIENT) Summons help and initiates CPR as required until initial assistance arrives and then assumes responsibility for airway management. Maintains airway patency with use of airway adjuncts as required (suction, high flow oxygen, via Hudson mask, blob mask with O2 or bag valve mask ventilation).
Cont…….. This role becomes the responsibility of the PICU nurse on their arrival. Assist with intubation and securing of ETT Inserts gastric tube and/or facilitates gastric decompression post intubation as required. Assists with ongoing management of airway patency and adequate ventilation Supports less experienced staff by coaching/guidance e.g. drug preparation
COMPRESSION NURSE If CPR in progress, assume responsibility for cardiac compressions (this includes ensuring that staff doing compressions are changed at regular intervals (e.g. every 2 minutes) to avoid fatigue resulting in inadequate compressions being delivered) Assess pulses (including pulse volume) and capillary refill as required
SPECIAL CONSIDERATION: Although aids isn’t known to be transmitted in saliva, some health care professionals may hesitate to give rescue breath, especially if the victim has AIDS. For these reason, it is recommended that all health care professional should how to use disposable air way equipments.
CONCLUSION: CPR is the responsibility of a team of personnel and not one person in isolation. For cardiac arrest we strive to prevent when possible, treat effectively when challenged and support humanely when death is imminent.
