Oxygen Therapy PowerPoint Presentation By Ibrahim Alhassan

Introduction

• Oxygen therapy is the administration of oxygen at a concentration greater than that found in the environmental atmosphere.
• At sea level, the concentration of oxygen in room air is 21%.
• The goal of oxygen therapy is to provide adequate transport of oxygen in the blood while decreasing the work of breathing and reducing stress on the myocardium.
• Oxygen transport to tissues depends on factors such as
• Cardiac output
• Arterial oxygen content
• Concentration of hemoglobin
• Metabolic requirements. 

These factors must be kept in mind when oxygen therapy is considered.

Indications for Oxygen Therapy

• A change in the patient’s respiratory rate or pattern.
• These changes may result from hypoxemia or hypoxia.
• O2 is usually administered to treat hypoxemia caused by a variety of problems such as
• Respiratory disorders (e.g., COPD, pulmonary HPT, pneumonia, pulmonary emboli)
• Cardiovascular disorders (e.g., M.I, dysrhythmia, angina pectoris, and cardiogenic shock)
• Central nervous system disorders (e.g., overdose of opioids, head injury, sleep disorders [sleep apnea])
