In children, the initial compensatory response to shock is an increase in heart rate. They rely more on heart rate to maintain cardiac output because their stroke volume can’t be ramped up as effectively as in adults. As shock begins, the sympathetic system kicks in, pushing the heart to beat faster to preserve perfusion despite falling preload. Blood pressure often stays normal early due to vasoconstriction, so it’s not the first sign to change. Respiratory rate and oxygen saturation can vary and may rise or stay normal in the early stages, but tachycardia is the most consistent and earliest detectable change guiding you that the patient is entering shock.
