KIN 125 Lecture Notes - Lecture 5: Ventricular Fibrillation, Tachycardia, Brachial Artery
Document Summary
Signs and symptoms: chest pain (radiation to shoulders, neck, jaw, or arms, nausea/vomiting, cool, pale, moist skin, weak or irregular pulse, breathing difficulties. The cardiac chain of survival: early recognition and access, early cpr, early defibrillation, early advanced life support (ems) The brain begins to die without oxygen: 0-1 minutes cardiac irritability, 0-4 minutes. Brain damage not likely: 4-6 minutes. Brain damage very likely: more than 10 minutes irreversible brain damage. The life support sequence: survey the scene, determine responsiveness, activate the ems system, open the airway, determine brathing, provide rescue breathing, determine pulse/circulation, determine appropriate care, start rescue breathing, deliver chest compressions, defibrillate when needed. If there is a pulse: begin rescue breathing, continue in 2 minute cycles, stop when pulse stops or ems arrives. If there is no pulse: bare the chest, begin cpr, obtain and apply aed. Hand placement: find the lowest point on ribs, slide 2 fingers up where rib cage meets sternum.
