Study Notes
Medical Gas Therapy
- Medical gas therapy involves the use of laboratory, therapeutic, and anesthetic gases
- Physical characteristics of these gases include:
- Laboratory gases: used for diagnostic and analytical purposes
- Therapeutic gases: used for medical treatment and therapy
- Anesthetic gases: used to induce anesthesia and sedation
Manufacture, Transport, and Storage of Medical Gases
- Medical gases are manufactured through various methods, including air liquefaction and gas separation
- They are transported in cylinders or pipelines and stored in specialized facilities
Medical Gas Regulation Devices
- Devices regulate the flow and pressure of medical gases
- They ensure safe and controlled delivery of gases to patients
Hypoxemia and Hypoxia
- Hypoxemia: decreased oxygen content in arterial blood (CaO2)
- Hypoxia: inadequate oxygen availability for tissue cells to function
- Shunt: abnormal or normal (physiologic) bypass or diversion of fluid, including mixing of low-oxygen systemic venous blood with high-oxygen arterial blood
Medical Gas Therapy Indications
- Medical gas therapy is indicated for various medical conditions, including respiratory disorders, cardiovascular diseases, and anesthesia
Oxygen Therapy
- Oxygen therapy is used to treat hypoxemia and hypoxia
- Clinical goals of oxygen therapy include improving oxygenation, relieving respiratory distress, and supporting cardiovascular function
Oxygen Toxicity
- Oxygen toxicity occurs when 100% oxygen is breathed at sea level
- Time sequence for toxic damage: 4-6 hours, 12-14 hours, and 24 hours
- Symptoms include convulsions, lung damage, and absorptive atelectasis
Oxygen Delivery Systems
- Fixed performance and variable performance oxygen delivery systems are used
- Systems include nasal cannulas, masks, and mechanical ventilators
High-Flow Nasal Cannula Systems and Extracorporeal Membrane Oxygenation
- High-flow nasal cannula systems deliver high flows of heated and humidified oxygen
- Extracorporeal membrane oxygenation (ECMO) is a life-support system that oxygenates blood outside the body
Hazards Associated with Oxygen Therapy
- Physical and environmental hazards include fire, explosions, and oxygen toxicity
- Invasive and non-invasive methods are used to assess oxygen therapy, including pulse oximetry and blood gas analysis
