- Increasing severity of shock (worsening tissue hypoperfusion) is associated with increasing heart rate (HR), worsening hypotension and worsening metabolic acidosis.
[References]
- Physiological compensation to maintain adequate tissue perfusion and oxygen delivery results in measurable changes in heart rate. Once these compensatory mechanisms are exhausted a progressive decline in blood pressure can be measured. Multiple confounding factors may also affect these vital signs.
[References]
- Traditional vital signs (HR and SBP) have limitations as indicators of blood loss.
