During CPR generic atrovent 20mcg otc, correct reversible causes The carotid pulse should be checked only if the If not done already: Defibrillate • Check electrode/paddle positions and ECG changes to a rhythm compatible with a cardiac output. In addition, successful defibrillation CPR 3 minutes after is often followed by a period of apparent asystole before a 1 minute • Consider: Amiodarone, atropine/ defibrillation) coordinated rhythm is established. Even if a rhythm that is pacing, buffers normally compatible with a cardiac output is obtained, a period Potentially reversible causes of impaired myocardial contractility often occurs, resulting in • Hypoxia a weak or impalpable carotid pulse. It is important not to make • Hypovolaemia a spurious diagnosis of pulseless electrical activity under these • Hyper- or hypokalaemia and metabolic disorders • Hypothermia circumstances; for this reason the algorithm recommends only • Tension pneumothrax one minute of cardiopulmonary resuscitation (CPR) before • Tamponade reassessment of the rhythm and a further pulse check. Adapted from Resuscitation Guidelines 2000, London: Resuscitation ventilation is continued at a rate of about 12 ventilations per Council (UK), 2000 minute. Continuous chest compressions may be possible with a laryngeal mask airway (LMA), but the seal around the larynx must prevent gas leaking and permit adequate ventilation of the lungs. If this is not possible, chest compressions should be interrupted to allow the usual 15:2 compression:ventilation ratio. Intravenous access should be established at an early stage in the management of cardiac arrest. Tracheal intubation is central veins allows drugs to be delivered rapidly into the the preferred method, but this depends on the experience of the rescuer; the LMA or Combi-tube are acceptable alternatives. In most circumstances peripheral venous cannulation is a concentration of oxygen as possible quicker, easier, and safer. The choice will be determined by the skills of those present and the equipment available. In recent recommendations on the treatment of patients with VF refractory to initial attempts at defibrillation, anti-arrhythmic drugs have achieved less prominence. Amiodarone is currently recommended in the United Kingdom as the agent most likely to be successful in this situation.
