CARDIO PULMONARY RESUSCITATION BY ASHOK BISHNOI Lcturer,JINR
INTRODUCTION:- Sudden death occur when heartbeat & breathing stop suddenly or unexpectedly. the major role of CPR is to provide oxygen to heart ,brain,& the other vital organ until medical treatment (advance cardiac life support-ACLS) can restore normal heart action .
DEFINITION:- Angela Morrow RN Cardiopulmonary resuscitation (CPR) is a procedure used when a patient's heart stops beating and breathing stops. It can involve compressions of the chest or electrical shocks along with rescue breathing. Mosby medical dictionary CPR is a basic emergency procedure for life support consisting of artificial and manual external cardiac massage .
Fluid imbalance extensive hemorrhage, hypotension, shock Neurological causes brain injuries, massive cva Poisons substance and drug overdose co poisoning, propanolol over dose Other causes electrical shock, hypothermia, narcotic overdose
WARNING SIGNS OF CARDIO PULMONARY ARREST :- Early signs: . loss of consciousness & convulsions Late signs: . Apnoea .Dilated pupils .Absence of heart sounds
Other signs Changes in respiratory rate A weak or irregular pulse Bradycardia Cyanosis Hypothermia
CPR PROCEDURE
EQUIPMENTS Ambu bag and masks with different size. Oropharyngeal airways. Endotracheal tubes of appropriate sizes and stillet.
Paediatric laryngoscope with straight (Miller) and curved (McIntosh) blade – Appropriate sizes. v. Suction apparatus. vi. NG tube.
STEPS FOR CPR:- Airway:- Maintaining an open airway. Breathing:- Providing artificial ventilation by rescue breathing. Circulation:- Promoting artificial circulation by external cardiac compression. Defibrillation:- Restoring the heart beat.
Shake shoulders gently Ask “Are you all right?” If he responds Leave as you find him. Find out what is wrong. Reassess regularly. CHECK RESPONSE
Method: Mouth to mouth ventilation Mouth to mask ventilation Bag mask ventilation
MOUTH TO MOUTH VENTILATION
MOUTH TO MASK VENTILATION
BAG MASK VENTILATION
NEONATAL PEDIATRIC ADULT
(C) Circulation:- Assess pulse {Adult}
Assess pulse (infant)
CHEST COMPRESSIONS
Place the heel of one hand in the centre of the chest Place other hand on top Interlock fingers Compress the chest Rate 100 min -1 Depth 3-5 cm(1.5 to 2 inches) Equal compression : relaxation When possible change CPR operator every 2 min CHEST COMPRESSIONS
IN ADULT
IN CHILD
IN INFANT
(D) DEFIBRILLATION:- Device that delivers direct electrical current across the myocardium. The aim is to produce synchronous depolarization of cardiac muscle STRATEGIES: Test defibrillate for full battery charge switch on power button change paddle mode
Key issues: Paddle site : Rt intraclavicular region lt lower axillary region Paddle size : 8cm -12 cm wave form patterns : monophasic biphasic truncated exponential biphastic rectilinear
STEPS :- switch on select paddle mode assess rhythm press paddles firmly over the chest deliver the shock resume cpr
Intensive care:-(shifting in ICU) transfer to ICU monitor closely and continuously monitor vital signs every hour watch for convulsions intubate if necessary catheterize the patient and monitor output record the procedure
POST CARDIAC ARREST MANAGEMENT:- Continued care To ensure hemodynamic monitoring To minimize the effect of loss of spontaneous circulation of various organs To recognize and treat recurrent cardiac arrests Objectives: Optimize cardio pulmonary function& systemic perfusion Transport victim out of hospital Identify and treat thre precipating factor Intitute measure to prevent recurrence and improve neurological function
Respiratory system; I ntubate & mechanically ventilate until they are stable Administer supplemental oxygen Obtain chest x ray Administer drugs Avoid hyperventilation Cardio vascular system: Obtain expert consultation Monitor ecg , x-ray, lab analysis, Monitor intra arterial blood pressure Administer drugs
COMPLICATIONS OF CPR:-:- Rib fractures Laceration related to the tip of the sternum Liver, lung, spleen Aspiration Vmiting
