When should you contact EMS in cases of external bleeding?

In cases of external bleeding, it is crucial to assess the situation comprehensively. Contacting EMS becomes necessary when the bleeding does not stop despite the application of direct pressure, as this may indicate a more serious injury requiring professional medical attention. Additionally, if the individual becomes unconscious, this is a significant clinical sign of worsening conditions, as loss of consciousness can signify shock or severe blood loss.

Therefore, recognizing the combination of persistent bleeding and a change in the patient's level of consciousness is critical. Both scenarios indicate that immediate medical intervention is required, highlighting the importance of timely and appropriate action in emergency situations.
