The document discusses cardiopulmonary resuscitation (CPR) and key aspects of the chain of survival: 1) Early recognition and calling for help, such as using early warning scores to identify at-risk patients. 2) Early CPR and defibrillation if needed. Defibrillation should be performed with minimal interruptions to chest compressions. 3) Post resuscitation care including treating any reversible causes like hypoxia, tension pneumothorax, hypothermia, etc.

1. Cardiopulmonary resuscitation Dr.V.Ravimohan What I learned in the ILS training http://www.mrcogexam.net

4. Medical emergency team calling criteria Acute change in Physiology Airway Threatened Breathing All respiratory arrests Respiratory rate < 5/ min Respiratory rate >36/min Circulation All cardiac arrests Pulse rate <40/min Pulse rate > 140/min Systolic pressure <90 mmHg Neurology Sudden decrease in level of consciousness Decrease in GCS of > 2 points Repeated or prolonged seizures Other Any patient causing concern who doesn’t fit the above criteria

20. Shock able Rhythm

21. 3 possibilities

22. VT/VF persists

23. VF/VT still persists

29. Treatment for PEA

33. Treatment for asystole and slow PEA(rate <60 min -1 )

34. During CPR

35. Reversible causes 4H 4T Hypoxia Tension pneumothorax Hypovolaemia Tamponade,cardiac Hypo/Hyperkalaemia/metabolic Toxins Hypothermia Thrombosis

36. 4 H Hypoxia 100% oxygen Ensure adequate chest rise & bilateral breath sounds Hypovolaemia Crystalloid/Colloid Surgery Hyperkalaemia 12 ECG may help in the diagnosis Check for hypoglycaemia Hypothermia

37. 4T Tension pneumothorax May be a complication of inserting central venous catheter Signs: decreased air entry decreased expansion hyperresonance percussion on affected side Do: needle thoracocentesis Tamponade cardiac Cardiac arrest after penetrating chest trauma 2 reasons:A.hypovolaemia B.cardiac tamponade Do: needle pericardiocentesis or resuscitative thoracotomy Toxins Thrombosis Consider thrombolytic therapy
