Oxygenation and Nebulization: Parts, Indications and Methods

Oxygenation and Nebulization Both oxygenation and nebulization are fundamental concepts in respiratory care, essential for treating hypoxia and airway diseases like asthma, COPD, and respiratory infections. Oxygenation Oxygenation refers to the process of delivering oxygen (O₂) to the body’s tissues via the lungs and bloodstream. It is crucial for cellular metabolism and survival. Indications: Hypoxia (PaO₂ < 60 mmHg or SpO₂ < 90%) Respiratory failure Severe anemia Cardiac arrest Shock CO poisoning Postoperative support Methods of Oxygen Delivery 1. Low-Flow Oxygen Systems (Delivers O₂ mixed with room air) Device FiO₂ Delivered Flow Rate Nasal Cannula 24–44% 1–6 L/min Simple Face Mask 40–60% 5–10 L/min Partial Rebreather Mask 60–80% 6–10 L/min Non-Rebreather Mask 80–100% 10–15 L/min 2. High-Flow Oxygen Systems (Delivers fixed O₂ concentration) Device FiO₂ Delivered Flow Rate Venturi Mask 24–60% 4–15 L/min High-Flow Nasal Cannula (HFNC) Up to 100% >40 L/min Mechanical Ventilation 21–100% Variable Oxygen Toxicity: Cause…
