1. Overview and Medical Indications
What is Home Oxygen Therapy?
Home oxygen therapy involves the administration of supplemental oxygen at concentrations greater than ambient air (20.9%) to treat or prevent hypoxemia (low blood oxygen levels)[4]. This medical intervention is prescribed for patients with chronic respiratory conditions, cardiovascular diseases, or recovery from acute illnesses requiring continuous or intermittent oxygen support.
Medical Indications for Home Oxygen Therapy
According to international guidelines, home oxygen therapy is indicated for patients with documented hypoxemia, specifically[5]:
- Chronic Obstructive Pulmonary Disease (COPD) – Most common indication, with proven mortality benefit
- Interstitial lung disease – Including pulmonary fibrosis and pneumoconiosis
- Cystic fibrosis – Advanced stages with respiratory failure
- Pulmonary hypertension – Primary or secondary forms
- Chronic heart failure – With concurrent hypoxemia
- Sleep-related breathing disorders – Severe sleep apnea with hypoxemia
- Cluster headaches – High-flow oxygen for acute episodes
- Palliative care – For symptom relief in end-stage diseases
Laboratory Criteria for Oxygen Prescription
International standards require documented hypoxemia with the following criteria[6]:
| Patient Category | PaO₂ (mmHg) | SpO₂ (%) | Additional Criteria |
|---|---|---|---|
| Standard Indication | ≤ 55 | ≤ 88 | Stable condition, room air |
| With Complications | 56-59 | ≤ 89 | Cor pulmonale, CHF, hematocrit >56% |
| Nocturnal Hypoxemia | Normal at rest | ≤ 88 during sleep | Sleep study documentation |
| Exercise-Induced | Normal at rest | ≤ 88 with activity | 6-minute walk test |
2. Oxygen Delivery Equipment and Systems
Types of Home Oxygen Systems
Three primary oxygen delivery systems are available for home use, each with distinct advantages and applications[7]:
Oxygen Concentrators
Mechanism: Extracts oxygen from ambient air using molecular sieve technology
Advantages: Continuous supply, cost-effective for long-term use, no refills required
Limitations: Requires electricity, backup power needed, noise production
Flow Rate: 1-10 L/min (standard), up to 15 L/min (high-flow units)
Oxygen Purity: 90-96% at prescribed flow rates
Compressed Gas Cylinders
Mechanism: Stores 100% oxygen under high pressure (2000-3000 PSI)
Advantages: Portable, no electricity required, 100% oxygen purity
Limitations: Limited supply duration, requires regular refills, heavy weight
Flow Rate: 0.5-15 L/min with appropriate regulators
Duration: Varies by tank size (E-tank: 5-6 hours at 2 L/min)
Liquid Oxygen Systems
Mechanism: Stores oxygen in liquid form at -183°C in insulated containers
Advantages: High capacity, portable ambulatory units, pure oxygen
Limitations: Expensive, requires specialized handling, evaporation losses
Flow Rate: 0.25-15 L/min with precise flow control
Capacity: 30-40 L liquid = 25,000-32,000 L gaseous oxygen
Oxygen Delivery Devices
The choice of delivery device depends on the patient’s oxygen requirements, breathing patterns, and comfort preferences[8]:
| Device Type | Flow Rate (L/min) | FiO₂ Delivered | Advantages | Disadvantages |
|---|---|---|---|---|
| Nasal Cannula | 1-6 | 24-44% | Comfortable, allows eating/talking, well-tolerated | Variable FiO₂, mouth breathing reduces effectiveness |
| Simple Face Mask | 5-10 | 40-60% | Higher FiO₂ than cannula, good for acute needs | Claustrophobic, interferes with eating/talking |
| Venturi Mask | 4-15 | 24-60% | Precise FiO₂ control, ideal for COPD patients | Bulky, requires specific flow rates for each FiO₂ |
| Non-Rebreather Mask | 10-15 | 80-95% | Highest FiO₂ delivery, reservoir bag system | Rarely used at home, requires high flow rates |
