Cardiovascular Disorders Hypertension High B/P Systolic above 140 or Diastolic above 90 Usually caused by narrowed blood vessels

Cardiovascular Disorders Hypertension Treat with: Lifestyle changes Diet changes Exercise Low salt intake Drugs Reduce Stress

Cardiovascular Disorders CAD Coronary Artery Disease Arteries that supply heart with O 2 become narrow or hard Usually caused by fat build up

Cardiovascular Disorders CAD Can lead to heart attack (Myocardial Infarction) More common in men

Cardiovascular Disorders CAD Treat with Lifestyle changes Diet changes Exercise Low salt intake Drugs Surgical procedures

Cardiovascular Disorders Angina Chest pain due to reduced blood flow to part of the heart muscle. Tightness, pressure, squeezing. Often relieved by rest or nitroglycerine tablets

Cardiovascular Disorders Myocardial Infarction Heart Attack Treat with: Drugs Surgical procedures Rehab

Cardiovascular Disorders Heart Failure CHF – Congested Heart Failure Weakened heart cannot pump blood normally Blood backs up Congestion occurs

Cardiovascular Disorders Heart Failure Right CHF – blood backs up into venous system. Left CHF – blood backs up into lungs. Feet and ankles swell Difficulty breathing Abdomen fills with fluid Bloody sputum Liver fails Body does not get enough O 2 Poor blood flow to brain B/P drops

Cardiovascular Disorders Patient care for CHF – Promote rest and activity as ordered I&O Weigh QD Restrict fluids as ordered TED hose Semi Fowlers position

Respiratory Disorders COPD Chronic Obstructive Pulmonary Disease: • Bronchitis • Emphysema • Asthma Interferes with O 2 and CO 2 exchange in the lungs

Respiratory Disorders COPD Obstructs airflow Leading cause of death Smoking is the most common risk factor

Respiratory Disorders COPD Chronic Bronchitis: Inflammation of the bronchitis Cough that becomes productive O 2 and breathing exercises ordered

Respiratory Disorders COPD Emphysema: Alveoli enlarge Less elastic Decreases exchange of O 2 and CO 2 Extreme SOB Smoking is the most common cause of emphysema

Respiratory Disorders COPD Emphysema: Must stop smoking O 2, drugs and breathing exercise ordered Barrel Chest

Respiratory Disorders COPD Asthma: Airway inflamed and narrow Dyspnea Wheezing, coughing Triggered by allergies

Respiratory Disorders COPD Asthma: Sudden attacks can be life threatening Treated with drugs
