hyperemic

Thân thiện

The patient's hyperemic skin appeared red and warm to the touch.

Definition

1. Adjective: Pertaining to or characterized by hyperemia; affected by an excess of blood in a body part.

Usage

The adjective "hyperemic" is used in medical contexts to describe tissues, organs, or body parts that are in a state of hyperemia. It is typically used attributively (before a noun) or predictively (after a linking verb like "is" or "appears").

Examples

• The doctor noted that the patient's conjunctiva was hyperemic, indicating possible irritation or infection.
• A hyperemic response is a normal part of the inflammatory process following an injury.
• The skin around the wound appeared red and hyperemic.

Advanced Usage

• "Reactive hyperemia": This is a specific physiological process where blood flow increases dramatically to a tissue after a period of occlusion or ischemia. The tissue becomes hyperemic during this recovery phase.
  • After the blood pressure cuff was released, the forearm showed signs of reactive hyperemia.

Variants and Related Words

• Hyperemia (n): The condition itself; an excess of blood in the vessels supplying a body part.
  • The hyperemia was caused by the infection.
• Congested (adj): A more general synonym often referring to blockage or fullness, which can include fluid other than blood (e.g., nasal congestion). In specific contexts, it can be related.

Synonyms

• Engorged (specifically with blood)
• Flushed (when referring to skin, though this is less clinical)

Notes on Meaning

The term specifically denotes an active increase in blood flow due to dilated arterioles (active hyperemia) or a passive accumulation due to impaired venous outflow (passive hyperemia). It is a sign, not a disease itself, and points to underlying processes like inflammation, infection, or obstruction.
