Children can remain normotensive until what percentage of blood volume is lost?

Children can maintain a normal blood pressure despite significant blood loss due to their compensatory mechanisms. Typically, they can remain normotensive until they have lost approximately 25% of their total blood volume. This is because children possess a higher resilience and are able to tolerate greater fluid loss without showing immediate signs of shock or hypotension. The compensatory mechanisms include increased heart rate and vasoconstriction, which help maintain circulation and blood pressure as blood volume decreases. Understanding this threshold is crucial for emergency nurses when assessing pediatric patients who have experienced trauma or other events leading to blood loss, as it allows for timely interventions before the situation becomes critical.
