Answer:
Suction the airway with a catheter
Explanation:
It is given that a 57-year-old male has met with an accident and is struggling for life.
His noise is bleeding and he is finding it difficult to breathe thus breathing with an agonal gurgling sound. His respiration is inadequate and is having a rapid and weak pulse.
Thus the first life saving step to be taken is inserting a catheter in his mouth and suck the airway out of it so that the breathing becomes normal. By doing such more oxygen will pass onto the brain and the heart.
By this the person can be saved and now can wait for the arrival of the medical team.
Thus the answer is "Suction the airway with a catheter"
