Oxygen Therapy Principles
Oxygen therapy is one of the most frequently used clinical interventions in healthcare and plays a vital role in the treatment of patients experiencing acute or chronic respiratory compromise. While oxygen is considered an essential medicine, it must be prescribed, administered, monitored, and adjusted carefully to achieve therapeutic benefits while avoiding complications. Inappropriate oxygen administration can lead to serious adverse effects, making a sound understanding of oxygen therapy principles essential for all healthcare professionals involved in patient care.

Frequently asked questions
Oxygen therapy is the administration of supplemental oxygen to patients whose blood oxygen levels are lower than normal.
Oxygen therapy may be required for patients with conditions such as pneumonia, chronic obstructive pulmonary disease (COPD), asthma, heart failure, pulmonary embolism, trauma, sepsis, COVID-19
Oxygen is classified as a medication because it has specific indications, prescribed doses, target oxygen saturation ranges, potential side effects, and monitoring requirements.
Healthcare professionals monitor oxygen therapy using pulse oximetry, respiratory assessment, oxygen saturation levels, respiratory rate, work of breathing, heart rate, blood pressure, level of consciousness
Yes. Excessive oxygen administration may lead to hyperoxaemia, oxygen toxicity, absorption atelectasis, and worsening carbon dioxide retention in susceptible patients such as those with chronic obstructive pulmonary disease (COPD)
Patients should never smoke while using oxygen, keep oxygen away from open flames and heat sources, store oxygen cylinders securely, use equipment according to instructions, inspect tubing regularly, and seek medical advice
