How do paramedics assess for internal bleeding?

Paramedics assess for internal bleeding primarily through the evaluation of vital signs, such as hypotension (low blood pressure) and tachycardia (increased heart rate). When there is significant internal bleeding, the body often responds by increasing the heart rate in an effort to maintain adequate blood circulation and oxygen delivery to critical organs. At the same time, blood pressure may drop due to the loss of circulating blood volume. This physiological response serves as a red flag that indicates the possibility of internal bleeding.

In addition to monitoring vital signs, paramedics look for other signs and symptoms that could indicate internal bleeding, such as pallor, weakness, dizziness, and abdominal distension. Collectively, these indicators can help paramedics determine the urgency and nature of the situation, guiding them in their treatment decisions and transport plans for the patient.

Other methods, such as imaging techniques like ultrasound, are important for diagnosing internal bleeding in a clinical setting but are typically not available in the field. Relying on patient history and self-reported symptoms alone is also insufficient, as patients may not always be aware of the extent of their injuries. Therefore, identifying changes in vital signs such as hypotension and tachycardia is a crucial and immediate assessment step for paramedics
