A largo plazo de medida de la presión arterial en ratones con libertad de movimientos mediante telemetría

Overview

This protocol aims to assess systemic blood pressure in conscious freely moving mice using implantable radiotelemetry devices. This method is crucial for understanding vascular diseases and evaluating factors involved in blood pressure regulation.

Key Study Components

Area of Science

• Vascular physiology
• Telemetry techniques
• Animal models

Background

• Systemic blood pressure is a key indicator of vascular health.
• Traditional methods often involve restraint or anesthesia, which can introduce artifacts.
• Implantable telemetry allows for continuous monitoring in a naturalistic setting.
• Understanding blood pressure regulation is vital for addressing vascular diseases.

Purpose of Study

• To provide a reliable method for measuring blood pressure in mice.
