Study Notes
Oxygen Therapy Overview
- Oxygen therapy is the administration of oxygen at a concentration higher than ambient air (approximately 21% oxygen)
- It's crucial for various conditions where the body's oxygen levels are too low.
- Oxygen is a colorless, odorless, and tasteless gas essential for proper bodily functions and survival.
Learning Objectives
- Define oxygen therapy and its purpose.
- Identify different types of oxygen therapy.
- Outline procedures for administering oxygen therapy.
- Note potential complications of oxygen therapy.
Purposes of Oxygen Therapy
- Increase oxygen saturation in tissues when levels are below normal, due to illness or injury.
- Used to treat conditions like documented hypoxemia, severe respiratory distress (e.g., asthma, pneumonia), severe trauma, and chronic obstructive pulmonary disease (COPD), including chronic bronchitis, emphysema, and chronic asthma
- Treat pulmonary hypertension and acute myocardial infarction (heart attack).
- Often used as short-term therapy, such as post-anesthesia recovery.
- Used for treating chronic lung disease patients during exercise.
Methods of Oxygen Administration
- Low Flow Systems: These systems deliver oxygen that contributes partially to the inspired gas the patient breathes, the amount is dependent on the client's breathing. Examples include Nasal Cannula, Simple Masks, Partial Rebreathers, Non-rebreathers
- High Flow Systems: These systems deliver specific and constant oxygen percentages,independent of the client's breathing. Examples include Venturi Masks, Trach Collar, T-piece.
Oxygen Delivery Devices
- Nasal Cannula: A disposable plastic device with prongs inserted into the nostrils. Used for low to medium oxygen concentrations (24-44%).
- Simple Oxygen Mask: A clear, flexible plastic or rubber mask molded to the face. Delivers 35-60% oxygen at 6-10 liters per minute. Suitable for short-term use.
- Partial Rebreather Mask: Delivers oxygen concentrations up to 80% with a reservoir bag preventing the re-breathing of exhaled air. A minimum flow rate of 6 L/min is needed to maintain reservoir inflation.
- Non-Rebreather Mask: Provides the highest oxygen concentrations (95-100%) at 6-15 Liters per minute. A reservoir bag is used, and one-way valves prevent re-breathing exhaled air.
- Venturi Mask: Delivers specific and constant oxygen concentrations (40-50%) at 4-15 Liters per minute using a Venturi device. The specific oxygen concentration is determined by color-coded valves.
- T-piece: Used during ventilator weaning, providing accurate oxygen delivery and humidity to the patient.
Cautions and Complications
- Oxygen Toxicity: Can occur with inspired oxygen fractions (FIO2) greater than 50% for more than 48 hours.
- Infection: A possible complication that needs to be considered.
- Fire Hazard: Oxygen is a strong oxidizer.
Evaluation
- Assess the patient's breathing pattern, color of nail beds, lips, conjunctiva.
- Check for confusion, disorientation, cognition difficulties.
- Evaluate arterial oxygen concentration/hemoglobin.
- Monitor oxygen saturation with appropriate devices and methods.
Documentation
- Record the timing of oxygen therapy initiation.
- Document the method of delivery.
- Note oxygen concentrations and flow rates.
- Include patient observations.
- Add oronasal care instructions to the patient plan for care.
Equipment Specifications
- A table detailing oxygen delivery devices, flow rates, FIO2 (fraction of inspired oxygen), and special notes is included in a separate section for reference.
