Study Notes
Cardiovascular Physiology
- Diastole: Period when the heart ventricles are relaxed.
- Systole: Period when the heart ventricles are contracting.
- Blood Pressure: Force exerted against artery walls as blood is pumped, classified as systolic (>120) and diastolic (>80).
- Peripheral Vascular System: Comprises arteries, arterioles, capillaries, venules, and veins that carry oxygen-rich blood from the heart to tissues, facilitate gas exchange, and return carbon dioxide to the heart.
Hypertension
- Definition: High blood pressure, often termed HTN.
-
Risk Factors:
- Changeable: Diet (high sodium, low potassium), obesity, smoking, excessive alcohol, stress, diabetes.
- Non-changeable: Family history, age, genetics.
- Symptoms: Known as "The Silent Killer," symptoms include vague headaches and blurred vision.
- Complications: Can lead to damage in vital organs like the eyes, kidneys, heart, and brain.
- Treatment: Includes monitoring BP and lifestyle modifications (diet, exercise, stress reduction).
Hypertension Medications
-
Antihypertensives:
- ACE Inhibitors: Block formation of angiotensin II, leading to vasodilation, reduced fluid volume, and lowered BP.
- Beta-Blockers: Decrease heart rate and cardiac output; e.g., Metoprolol.
- Calcium Channel Blockers: Induce vasodilation by blocking calcium channels in arterial smooth muscle.
- Diuretics: Promote increased urine output and reduced fluid volume.
Peripheral Vascular Disorders
-
Key Medical Terms:
- Ischemia: Insufficient blood flow.
- Thrombophlebitis: Inflammation of a vein due to thrombosis.
- DVT (Deep Vein Thrombosis): Blood clot in a deep vein.
- PE (Pulmonary Embolism): Blockage in the pulmonary arteries.
Peripheral Arterial Disease (PAD)
- Description: Condition characterized by narrowed arteries, reducing blood flow to limbs.
- Symptoms: Pain (increase with elevation, decrease when dangling leg), pale skin, paresthesia, pulselessness, paralysis.
- Treatment: Focus on addressing clots and narrowed arteries; may include thrombolytics, antiplatelets (ASA, heparin), vasodilators, and statins (e.g., Atorvastatin).
Venous Disorders
- Venous Insufficiency: Caused by venous stasis and can lead to DVT.
- Risk Factors: Smoking, obesity, hypertension, and limited physical activity.
- Symptoms of Venous Insufficiency: Heavy, throbbing pain; dark, reddish coloration; leathery skin texture; and significant edema.
Assessment Techniques
-
Peripheral Vascular Assessment:
- Evaluate pulses (femoral, popliteal, pedal) and use Doppler ultrasound.
- Check capillary refill (<2 seconds), color (pale, dusky red, brown), and temperature.
- Assess for pain, edema, hair loss, wounds, ulcers, and neurological signs (numbness, tingling).

- Assess for pain, edema, hair loss, wounds, ulcers, and neurological signs (numbness, tingling).
Risk Factors for Deep Vein Thrombosis (DVT)
- Blood stasis due to immobility, particularly after surgery.
- Damage to the vein wall from trauma or surgical procedures.
- Increased blood coagulation, which can be influenced by genetic factors, medication, or health conditions.
Collaborative Care and Prevention of DVT
- Encourage mobility and leg exercises to promote blood flow.
- Use Intermittent Pneumatic Compression (IPC) devices to enhance circulation.
- Administer anticoagulants to prevent clot formation.
Nursing Process for Venous Disorders
- Conduct assessments to identify signs and symptoms of venous disorders.
- Formulate nursing diagnoses based on patient findings.
- Implement interventions such as bed rest and elevation of affected limbs.
- Evaluate patient responses to treatment and adjust care plans as necessary.
Patient Teaching Concepts for Venous Disorders
- Instruct patients on the importance of movement and leg exercises.
- Educate about the signs and symptoms of DVT, including calf pain, redness, swelling, and increased temperature.
- Discuss the use of compression stockings to reduce edema.
Thrombophlebitis
- Definition: Inflammation of a vein due to a clot (thrombus).
- Types: Can be classified as superficial or deep, with varying implications for treatment.

Aneurysm Definition
- An aneurysm is a localized bulging or dilation at a weak point in the artery wall, which can lead to serious complications if ruptured.
