Note:

The Shock Index (SI) is a simple and effective indicator used in emergency and critical care settings to quickly assess a patient’s cardiovascular condition. It helps healthcare professionals determine whether a patient is experiencing or approaching circulatory failure.

Explanation of Parameters:

• Heart Rate (HR): The number of times the heart beats per minute. An elevated heart rate may indicate stress on the body, dehydration, blood loss, or underlying medical conditions.
• Systolic Blood Pressure (SBP): The highest pressure in the arteries when the heart contracts. A lower SBP may suggest inadequate blood flow, which can be critical in trauma or shock scenarios.

Use of the Calculator:

This calculator allows users to input the patient’s heart rate and systolic blood pressure to determine the Shock Index. It assists medical professionals in identifying whether the circulatory system is functioning properly or under distress. It's especially useful in trauma, emergency, and pre-hospital settings.

Result Interpretation:

• SI less than 0.7: Normal — Indicates stable circulation.
• SI between 0.7 and 1.0: Caution — Could signal early circulatory imbalance; monitoring advised.
• SI greater than 1.0: Critical — Suggests possible circulatory failure; urgent intervention required.

Conclusion:

The Shock Index is a valuable early warning tool that helps detect potential cardiovascular compromise before more serious symptoms develop. By using this calculator, healthcare providers can make quicker, more informed decisions to ensure patient safety and improve outcomes in high-risk or emergency situations.
