Episode notes
Focus on MAP
- Focus on Mean Arterial Pressure (MAP) when assessing hypertension, as it's directly measured by automated cuffs.
- Systolic/diastolic readings from cuffs are extrapolated, making MAP more reliable, especially in critical care.
Target Organ Damage
- A hypertensive emergency is defined by target organ damage, not just high blood pressure readings.
- Examples include acute kidney injury, myocardial infarction, encephalopathy, and pulmonary edema.
Consider Baseline
- Consider a patient's baseline blood pressure when assessing hypertension.
- A chronically hypertensive patient with a high MAP might not be in an emergency if it's their usual state.
