A healthcare provider should use a finger sweep only when the provider can see solid material obstructing the airway of an unresponsive patient (Class indeterminate). No studies have evaluated the routine use of the finger sweep to clear an airway in the absence of visible airway obstruction. The recommendation to use the fingersweep in past guide lines was based on anecdotal reports that suggested that it was helpful for relieving an airway obstruction. but 4 case reports have documented harm to the victim or rescuer. 제발 도와줘요. ㅠㅠ
