What is a normal shock index?

The shock index (SI) is a bedside assessment defined as heart rate divided by systolic blood pressure, with a normal range of 0.5 to 0.7 in healthy adults.

What is a high shock index?

A shock index higher than 1.3 was moderately predictive of hospitalization (likelihood ratio, 6.64) and mortality (LR, 5.67). Lower values of shock index were also predictive, but less so. For example, a shock index higher than 0.9 was associated with a likelihood ratio for mortality of 2.59.

How do you calculate shock index?

The shock index (SI) is an indicator of the severity of hypovolemic shock and is calculated by dividing the heart rate (HR) by systolic blood pressure (SBP) [1].

What is shock index used for?

Shock index is known as hemodynamic stability. The accepted value of shock index ranges from 0.5 to 0.7. This index is commonly used to assess the amount of blood loss and degree of hypovolemic shock. However, shock index in clinical practice is used to assess hypovolemic shock or the severity of non-hypovolemic shock.

What are the 7 types of shock?

18.9A: Types of Shock

Hypovolemic Shock.
Cardiogenic Shock.
Obstructive Shock.
Distributive Shock.
Septic.
Anaphylactic.
Neurogenic.

What are the 3 stages of shock?

The three phases of shock: Irreversible, compensated, and decompsated shock.

What are the 3 levels of shock?

What are 4 stages of shock?

It covers the four stages of shock. They include the initial stage, the compensatory stage, the progressive stage, and the refractory stage.

What are the 4 types of shocks?

There are broadly four types of shock: distributive, cardiogenic, hypovolemic, and obstructive.

What is the shock index?

The Shock Index indicates level of occult shock, especially in trauma or acute hemorrhage, based on heart rate and systolic blood pressure. This is an unprecedented time. It is the dedication of healthcare workers that will lead us through this crisis.

How do you calculate shock index in nursing?

Calculating Shock Index. A very useful tool in determining the presence of shock is the Shock Index (SI). To calculate your patient’s Shock Index, divide heart rate by systolic blood pressure.

What is a normal shock index in sepsis?

This study shows that patients with a normal SI (less than 0.7) are 95% likely not to present with an established marker for severe sepsis – a high lactate level. A normal shock index may serve as an adjunct to inform the clinician of which patients to prioritize for care.
