The study aims to investigate how laypersons estimate bleeding and blood loss. Blood loss estimates and assessment of severity of the situation is a crucial part of decision making on first aid actions. In training in bleeding control, different types of instructions and comparisons are used to teach laypersons to judge if the bleeding is life-threatening or not; instructions can be descriptive such as “a pool of blood is present” or metaphorical as “half a can of soda”. The present study aims to investigate the effect of the different kinds of instructions on blood loss estimations. The study is performed online.
Previous research in the field has mainly focused on measures, how instructions should be formed so they lead to the correct first aid measure. We want to look at the effect of the different types of instructions, to be able to facilitate blood loss estimation. Knowledge on the effectiveness leads to better training efforts and training material.
