A chronic, progressive decline in cognition affecting memory and daily function, usually irreversible, in which abrupt worsening should prompt a search for a superimposed delirium.

Related: Delirium, Mental status examination
Mental status examination

A structured assessment of appearance, behavior, speech, mood, thought content, perception, cognition, insight, and judgment, documenting a baseline for later comparison.

Related: Delirium, Delirium
Focused assessment

A targeted examination of one body system or complaint, guided by the patient's history and presenting problem, to confirm or rule out likely causes quickly.

Related: ABCDE approach, Abnormal findings
ABCDE approach

A prioritized survey of Airway, Breathing, Circulation, Disability, and Exposure, repeated after each intervention to detect deterioration in a seriously ill patient.

Related: Focused assessment, Rapid response team
Rapid response team

A hospital team that can be summoned by any staff member when a patient shows early warning signs such as falling oxygen saturation or altered consciousness, before cardiac arrest occurs.

Related: ABCDE approach, Early warning score
Early warning score

A numeric score combining vital signs such as respiratory rate, oxygen saturation, blood pressure, pulse, temperature, and consciousness to flag patients at risk of deterioration.

Related: Rapid response team, ABCDE approach
Shock

Inadequate tissue perfusion from causes such as hemorrhage, sepsis, or pump failure, showing as low blood pressure, cool or mottled skin, altered mentation, and reduced urine output.

Related: Sepsis, Mean arterial pressure
Sepsis

Life-threatening organ dysfunction caused by a dysregulated response to infection, identified by signs such as altered mentation, low blood pressure, and rising lactate.

Related: Shock, Bundle of care
Mean arterial pressure

The average pressure driving blood into tissues across the cardiac cycle, estimated as one-third of pulse pressure plus diastolic pressure, with roughly 65 mm Hg needed for organ perfusion.

Related: Shock, Early warning score
