Study Notes
Critical Care: The Adult Client with Respiratory Disorder
- Focus on understanding ventilation and perfusion balance in respiratory disorders.
- Disruptions in the balance lead to conditions like low ventilation-perfusion ratios, commonly seen in patients with respiratory issues.
Chest and Lower Respiratory Tract Disorders
- Pneumonia: Inflammation caused by mucus accumulation in the lungs.
- Aspiration Pneumonia: Result from inhaling foreign materials into the lungs, leading to infection.
- Ventilator-Associated Pneumonia: Infection that occurs in patients on mechanical ventilation, often due to ventilator management practices.
- Pleural Effusion: Excess fluid buildup between the layers of tissue lining the lungs and chest cavity, affecting breathing.
- Chronic Obstructive Pulmonary Disease (COPD): Includes chronic bronchitis (mucus overproduction) and emphysema (destruction of alveolar walls).
- Asthma: Airway inflammation and constriction, leading to breathing difficulties.
- Pulmonary Edema: Fluid accumulation in the lungs, often due to heart issues.
- Pulmonary Embolism: Blockage in a pulmonary artery, can result in infarction (tissue death due to lack of blood supply).
- Acute Respiratory Distress Syndrome (ARDS): Severe inflammatory response leading to respiratory failure.
- Respiratory Failure: Occurs when the respiratory system fails to oxygenate blood or remove carbon dioxide effectively.
Mechanics of Ventilation
- Alveolar Surface Tension: Must be managed to prevent alveolar collapse.
- Lung Compliance: Refers to the lungs' ability to stretch and expand; affected by elastic fibers and surface tension.
- Pressure Gradient: Negative pressure within the lungs versus positive pressure outside creates a vacuum effect, essential for effective ventilation.
- Delivery of Oxygen: Must consider the pressure within the delivery system to ensure optimal oxygenation of blood.
Obstruction and Ventilation-Perfusion Mismatch
- Atelectasis: Collapse of alveoli, hindering gas exchange.
- Mucus Plug: An obstruction in the airways caused by accumulated mucus, blocking airflow.
- High Ventilation-Perfusion Ratio (Dead Space): Occurs when ventilation exceeds perfusion, leading to inadequate gas exchange.
- Pulmonary Infarction: Tissue damage in the lungs due to lack of blood flow, often linked to pulmonary embolism.
- Cardiogenic Shock: Can result from arrhythmias leading to decreased blood flow to vital organs, impacting respiratory function.
