Study Notes
- COPD is assessed by observing both chronic conditions and exacerbations.
- COPD risk factors include smoking, infection, asthma, air pollution, occupational hazards, aging, genetics, and AATD (Alpha-1 antitrypsin deficiency).
COPD Signs and Symptoms
- Chronic cough is a common symptom.
- Excessive sputum production is typical in COPD patients.
- Shortness of breath (dyspnea), especially during exertion, is a key indicator.
- Wheezing and chest tightness are often reported
- Frequent respiratory Infections are typical
- Reduced exercise tolerance is a sign of COPD.
- Breath sounds are usually identified as rhonchi.
- Air trapping occurs because persistent airflow limitation makes full exhalation difficult.
- Hyperinflation results from trapped air, increasing lung volume and reducing elasticity.
- Diaphragmatic changes include flattening, further contributing to chest expansion.
- Accessory muscles are used to compensate for impaired respiratory function.
- Loss of elastic recoil in the lungs due to alveolar wall damage contributes to hyperinflation.
- Clubbed fingers result from chronic hypoxia causing vascular and connective tissue changes.
- Rhonchi are low-pitched, "snoring" sounds, sometimes called low pitch wheezing.
- Dyspnea occurs on exertion along with a sense of a heavy chest.
- Increased work to breathe, air trapping, and barrel chest are signs of COPD.
- Pursed-lip breathing can help relieve anxiety, and slows respiration by providing positive pressure to open airways.
COPD Complications
- Hypoxia stimulates pulmonary arterial vasoconstriction.
- Chronic pulmonary vasoconstriction can lead to pulmonary hypertension.
- Pulmonary hypertension increases workload of the right ventricle, potentially causing right-sided heart failure.
Cheyne-Stokes Respirations
- Cheyne-Stokes respirations involve alternating periods of hyperventilation and apnea.
- Often seen in clients who are unconscious, comatose, or nearing death.
- Hypoxia stimulates pulmonary arterial vasoconstriction.
Fatty Emboli
- Fatty embolism is characterized by fat globules obstructing blood vessels, causing tissue damage.
- Fatty embolism syndrome (FES) includes the symptoms resulting from fat embolism.
- Fatty emboli commonly occur after fractures of long bones but can develop in other situations.
- Fat emboli originate from bone marrow fat cells entering the bloodstream after a fracture.
- Fractures, especially of long bones, are common causes of fatty emboli.
- Non-traumatic causes include elective orthopedic procedures, such as joint replacements.
- Fat emboli most commonly travel to and affect the lungs, followed by the brain and skin.
- FES typically presents 24 to 72 hours after the initial injury or surgery.
- Respiratory symptoms of FES include shortness of breath, chest pain, and cough.
- Neurological symptoms include altered mental status, confusion, and focal neurological deficits.
- Dermatological symptoms include petechiae, especially on the upper body and chest.
- Fever and tachycardia may also be present.
- Diagnosis of fatty embolism and FES is based on clinical findings and imaging studies.
- Early manifestations of fatty emboli include tachypnea, dyspnea, hypoxemia, and anxiousness.
- Late manifestations include petechiae and neurological changes.
- Treatment focuses on supportive care.
- Oxygen therapy is needed to address respiratory symptoms.
- Intravenous fluids and hemodynamic support are used.
- Mechanical ventilation may be required if respiratory failure occurs.
- Prevention includes early stabilization of fractures and cautious handling of bones during surgery.
- A Brazilian Butt Lift (BBL) carries a risk of fat emboli due to fat harvesting and injection.
DVT Prevention
- Encourage ambulation.
- Use compression stockings.
- Administer prophylactic anticoagulants to high-risk patients.
Pneumothorax
- Interventions include chest tube placement to evacuate air and restore lung function.
- Avoid actions that can worsen the pneumothorax, such as high-pressure ventilation.
