Definition

1. Noun:
   • The pressure exerted by circulating blood upon the walls of arteries: "Arterial pressure" is a physiological measurement representing the force of blood flow against arterial walls. It is a product of cardiac output and systemic vascular resistance.

Usage

• "Arterial pressure" is a technical medical term. It is typically measured in millimeters of mercury (mmHg) and is a critical vital sign. It is often discussed in clinical and physiological contexts.
• It is commonly used with verbs like , , , , , and .
• It is often modified by adjectives indicating its state, such as , , , , or .

Examples

• Noun:
  • The nurse recorded the patient's arterial pressure as 120/80 mmHg.
  • Hypertension is a condition of chronically elevated arterial pressure.
  • The medication aims to reduce systemic arterial pressure.

Advanced Usage

• "Mean arterial pressure (MAP)": A calculated average pressure in the arteries during one cardiac cycle, crucial for assessing blood flow to organs.
  • A mean arterial pressure above 65 mmHg is often targeted in critical care.
• "Systemic arterial pressure": Specifies the pressure within the systemic circulation, as opposed to the pulmonary arteries.
  • The study focused on the regulation of systemic arterial pressure.

Variants and Related Words

• Blood pressure: A more common, near-synonymous term in general usage, though "blood pressure" can refer more broadly to pressure in various vessels, while "arterial pressure" is more specific.
• Hypertension: The medical condition of high arterial pressure.
• Hypotension: The medical condition of low arterial pressure.

Synonyms

• Blood pressure (in common, non-technical contexts).

Related Phrases

• Arterial pressure monitoring: The continuous measurement of arterial pressure, often via an invasive catheter.
  • The patient in the ICU required arterial pressure monitoring.
• Arterial pressure waveform: The visual representation of arterial pressure changes over time during a heartbeat.
  • The shape of the arterial pressure waveform can provide diagnostic clues.
