Standard Operating Procedure: Oxygen Administration

This Standard Operating Procedure (SOP) outlines the clinical protocol for the safe and effective administration of supplemental oxygen to patients in respiratory distress or hypoxemic states. Adherence to these guidelines ensures patient safety, minimizes the risk of combustion, and maintains compliance with medical safety standards. All staff must confirm a physician’s order or follow established emergency clinical protocols prior to initiation.

Phase 1: Preparation and Safety

• Verification: Confirm the patient’s identity and review the clinical order for oxygen (flow rate and delivery device).
• Safety Check: Ensure a "No Smoking" sign is posted in the immediate area. Verify that no open flames, spark-producing equipment, or petroleum-based products (e.g., Vaseline) are near the oxygen source.
• Equipment Inspection: Check the oxygen tank pressure or wall outlet functionality. Ensure all tubing is free of kinks or obstructions.
• Hand Hygiene: Perform a full hand-wash or apply alcohol-based sanitizer according to infection control protocols.

Phase 2: Equipment Assembly

• Flowmeter Attachment: Securely attach the flowmeter to the wall oxygen outlet or regulator on the portable cylinder.
• Humidification (If ordered): If flow rate exceeds 4L/min, attach a humidifier bottle filled with sterile water to prevent mucosal drying.
• Device Attachment: Connect the designated delivery device (Nasal Cannula, Simple Face Mask, or Non-Rebreather) to the flowmeter outlet.
• Flow Calibration: Open the flowmeter valve slowly to the prescribed liter flow rate before placing the device on the patient.

Phase 3: Patient Application and Monitoring

• Positioning: Assist the patient into a high-Fowler’s position (or the position of comfort) to optimize lung expansion.
• Device Placement:
  • Nasal Cannula: Place prongs into the nares with the curve facing downward. Adjust the slide loop under the chin.
  • Mask: Position the mask over the nose and mouth, tightening the elastic strap for a secure seal.
• Skin Integrity: Apply padding (e.g., gauze) behind the ears or over bony prominences where the tubing or elastic straps make contact to prevent pressure ulcers.
• Monitoring: Verify oxygen saturation (SpO2) via pulse oximetry within 5 minutes of initiation. Assess respiratory rate, effort, and skin color.

Pro Tips & Pitfalls

• Pro Tip: Always document the exact time of initiation, the flow rate, the delivery device used, and the patient's objective response (SpO2, work of breathing) in the Electronic Health Record (EHR).
• Pitfall - The "Closed Reservoir" Error: When using a Non-Rebreather mask, ensure the reservoir bag is inflated before placing it on the patient. If the bag is flat, the patient is not receiving the intended concentration of oxygen.
• Pitfall - Over-tightening: Avoid overtightening straps. This causes skin breakdown and discomfort, leading to decreased patient compliance. Check pressure points every 4 hours.

FAQ: Oxygen Administration

1. At what flow rate should I start using a humidifier? Generally, humidification is recommended for oxygen flow rates exceeding 4 Liters per minute (L/min) to prevent drying of the nasal mucosa and irritation of the airways.

2. What should I do if the patient’s SpO2 does not improve after starting oxygen? Check for equipment failure (kinked tubing or empty cylinder), ensure the mask has a good seal, and immediately reassess the patient’s airway and breath sounds. Notify the attending physician immediately if clinical status declines despite intervention.

3. Is it safe to leave oxygen equipment in the hallway? No. Portable oxygen cylinders must be secured in an approved rack or carrier at all times. They should never be left standing upright without support, as they can become dangerous projectiles if the valve is damaged.
