CARDIOPULMONARY RESUSCITATION DR SUJATA PROFESSOR DEPT.OF ANAESTHESIOLOGY &CRITICAL CARE UCMS & GTB HOSPITAL
CPBR/ CPCR • CPR • Cardiopulmonary brain resuscitation -CPBR • Cardiopulmonary cerebral resuscitation-CPCR
Goal Support & restore effective oxygenation, ventilation and circulation with return of intact neurological function. Intermediate Goal: Return of spontaneous circulation (ROSC)
Approach • BLS ( Basic Life Support) Primary survey. • ACLS (Advanced Cardiovascular Life Support) Secondary survey
Cardiopulmonary Resuscitation ACLS PROLONGED LIFE SUPPORT BLS A - Airway B - Breathing C - Circulation D- Defibrillation
Does BLS work? • BLS- maximum attention of public • .MMajority(70-80%) of cardiac arrests • Out-of-Hospital • .Pre-hospital care –key factor • ajority(70-80%) of cardiac arrests • Out-of-Hospital • .Pre-hospital care –key factor
CHAIN OF SURVIVAL Early Defibrillation Early ACLS Early access Early CPR 1.Recognition of Early warning signs 2.Activation of Emergency Medical Services 3.Basic CPR 4.Defibrillation
Before BLS Primary Survey • Scene safety • Check responsiveness • Activate EMS and get AED Assess & Perform appropriate action. Performance of the action improves chances of survival and better neurological outcome
BLS Primary survey • Support/ restore effective oxygenation, ventilation and circulation until ROSC or ACLS team takes over. • No advanced interventions- airway tech./ drugs (use universal precautions) • Early CPR and early defibrillation
Basic airway skills • Head tilt- chin lift • Jaw thrust without head extension (? Cx spine trauma) • Mouth- to- mouth ventilation • Mouth- to- nose ventilation • Mouth- to- barrier device (pocket mask) • Bag-mask ventilation
A C B AIRWAY BREATHING CIRCULATION DEFIBRILLATION D
Airway • Head tilt, Chin lift, Jaw thrust • AVOID HEAD TILT IF TRAUMA • Keeping airway open- LOOK, LISTEN, FEEL • LOOK LISTEN FEEL • CHEST MOVEMENTS BREATH SOUNDS AIR FLOW • RESP. RATE VOICE QUALITY CHEST MOVEMENTS • CYANOSIS ABNORMAL SOUNDS TRACHEAL POSITION • TRAUMA • FLUID/BLOOD /VOMITING • NOT MORE THAN 10 SECONDS
BREATHING ABSENT BREATHING PRESENT • 2 EFFECTIVE RESCUE BREATHS • SLOW BREATHS • TIDAL VOL. 8-10 ml/kg • Deliver in one sec. • Rate- 10-12/min. • Chest rise/ expand RECOVERY POSITION AND TRANSPORT
Assessing the victim • 1-- Make sure the victim, any bystanders, and you are safe. • 2-- Check the victim for a response. • Shake shoulders gently • Ask “Are you all right • If he responds • Leave as you find him. • Find out what is wrong. • Reassess regularly • If he does not respond: • Activate Code Blue and get AED • 4 --Keeping the airway open, look, listen, and feel for normal breathing. • OPEN AIRWAY • Look, listen and feel for NORMAL breathing • Do not confuse agonal breathing with NORMAL breathing
Keeping the airway open, look, listen, and feel for normal breathing. ……OPEN AIRWAY
If he is breathing normally• Turn him into the recovery position• Send or go for help, or call for an ambulance.• Check for continued breathing.
If he is not breathing normally • Give 2 rescue breaths • Pinch the nose • Take a normal breath • Place lips over mouth • Blow until the chest rises • Take about 1 second • Allow chest to fall • Repeat
Chest Compressions • Patient positioning: Firm and hard surface (ground, table/ hard bed) deflate air/ water mattresses. • Rescuer's position: Level with patient, elbows vertically straight and locked, shoulders directly above the hands, heel of one palm over the other. • Site : sternum in inter-mammary line. • Depth: 11/2- 2 inches. • Rate:100 per minute (5 cycles of 30:2-C:V over 2 min.). • Allow complete chest recoil.
Hands off- time • Less than 10 sec. • Specific interventions: defibrillation, advanced airway, moving the patient. Avoid : • Prolonged rhythm analysis • Frequent pulse checks • Too long breaths • Unnecessary moving the pt.
CHECK FOR SIGNS OF CIRCULATION PULSE PRESENT PULSE ABSENT / NOT DETECTED CONTINUE VENTILATION TILL SPONTANEOUS RESPIRATION • PULSE CHECK • NOT RECOMMENDED FOR LAY RESCUERS • POOR SENSITIVITY-55% • POOR SPECIFICITY-90% • ACCURACY RATE -65% • CHEST COMPRESSIONS • Rate: 100/MIN., SITE- Sternal depression -1.5 in.-2 in. • Universal compression-ventilation ratio (30:2) - Recommended for all • single rescuers of infant, child and adult victims (excluding newborns) • Two Rescuers = 30:2- ALL ADULTS, • 15:2 – Infants and child • PURPOSE : PUSH HARD,PUSH FAST
Defibrillation • AED: Follow the prompts. • Manual defibrillator: Analyse rhythm, shockable- decide shock (Monophasic 360 J, Biphasic 120-200 J ), apply gel, charge, clear the patient, no inflammables (incl. oxygen), deliver shock….. Resume CPR immediately.

ACLS Secondary survey Advanced, invasive assessment and management techniques required. Basic airway adjuncts: OPA, NPA Advanced Airway interventions: Combitube, LMA, Endotracheal intubation. Advanced circulatory interventions: Drugs to control heart rhythm and blood pressure.

PROBLEMS AND COMPLICATIONS OF CHEST COMPRESSIONS • RIB FRACTURES • FRACTURE STERNUM • RIB SEPARATION • PNEUMOTHORAX • HEMOTHORAX • LUNG CONTUSIONS • LIVER LACERATIONS • FAT EMBOLI • HIV, HEPATITIS • INFECTIONS MANAGE ACCORDINGLY BUT CONTINUE CPR
EFFECTIVE CHEST COMPRESSION WITH MINIMAL HANDS OFF IS KEY FOR EFFECTIVE CPR
When to stop BLS • ROSC, Conscious pt. • ACLS team takes over • Rescuer tired
DRUGS • EPINEPHRINE • Peripheral vasoconstriction- -adrenergic • Increase in Central aortic perfusion pressure • Decrease Threshold for Defibrillation • Fine VF to Coarse VF
DRUGS • For Rhythm • Amiodarone • Lidocaine • Atropine • Magnesium • For Blood Pressure • Epinephrine • Vasopressin • DOPAMINE-2-4 micro/kg/min.-DA rec • 4-10 micro/kg/min- Beta-rec. • 10-20 micro/kg/min- Alpha rec.
