The Utility of the Shock Index in Patients with Acute Respiratory Failure
Abstract
The shock index (heart rate divided by systolic blood pressure) reflects the overall cardiovascular status and is usually ≤ 0.7 heart beats per minute per mmHg. An increased shock index in patients undergoing emergent intubation for acute respiratory failure can identify patients who are at risk for post-intubation hypotension.
