Lecture Notes: Peripheral Vascular Disease (PVD)

Introduction

• Speaker: Nurse Mike
• Platform: SimpleNursing.com
• Topic: Peripheral Vascular Disease (PVD)
• Case Study: Norma, a 63-year-old female with calf pain when walking, diabetes, hyperlipidemia, and hypertension

Key Definitions

• Peripheral Vascular Disease (PVD): Broad term for diseases affecting both veins and arteries.
• Peripheral Venous Disease (PVD): Disease specific to the veins, blood can't return to the heart properly.
• Peripheral Arterial Disease (PAD): Condition where narrowed arteries reduce blood flow to extremities.

Pathophysiology

• Arteries: Pump oxygenated blood away from the heart.
• Veins: Vacuum deoxygenated blood back to the heart.
• Pressure: Arteries have higher pressure, veins have lower pressure.
• Oxygen Issue:
  • PVD: No oxygen supply issue, veins are problematic.
  • PAD: Critical issue, low oxygen, worse condition.

Detailed Breakdown

Peripheral Venous Disease (PVD)

• Common Symptoms:
  • Blood pooling in legs
  • Edema
  • Irregularly shaped sores
  • Dull pain rather than sharp
  • Yellow and brown ankles
• Acronym (VEINY):
  • Volumptuous pulses
  • Edema
  • Irregularly shaped sores
  • No sharp pain
  • Yellow and brown ankles
• Key Point: No oxygen transport issues, but blood returns inefficiently to the heart.

Peripheral Arterial Disease (PAD)

• Common Symptoms:
  • Low or no pulses
  • Cold legs
  • Sharp calf pain when walking
  • Tissue death (necrosis)
• Acronym (BAD):
  • Low blood flow
  • Low oxygen
  • Severe condition
• Key Point: Major oxygen transport problem, making it more severe than PVD.

Management & Care Priorities

• Recognize Symptoms: Early detection can help manage and mitigate risks.
• Monitor: Pay attention to pulse, temperature, and pain in extremities.
