Standard Operating Procedure: Oxygen Administration

This Standard Operating Procedure (SOP) outlines the clinical protocol for the safe and effective administration of supplemental oxygen. Ensuring the correct delivery method, flow rate, and patient monitoring is critical to preventing hypoxemia and mitigating risks associated with gas therapy, such as equipment failure or oxygen toxicity. All personnel must strictly adhere to facility safety guidelines and verify physician orders before initiation.

1. Preparation and Safety Protocols

• Verify Physician Order: Confirm the prescribed flow rate (LPM) and delivery device.
• Patient Identification: Use two patient identifiers (e.g., name and DOB).
• Assess Patient Status: Monitor baseline SpO2, respiratory rate, and physical distress.
• Safety Check: Ensure "No Smoking" signs are posted. Ensure the oxygen source (tank or wall outlet) is secured and functional.
• Equipment Inspection: Check the flow meter for proper attachment and the oxygen tubing for kinks or disconnections.

2. Selection and Setup of Delivery Device

• Nasal Cannula (1-6 LPM): Used for low-flow support; check for proper fit around ears and nares.
• Simple Face Mask (5-10 LPM): Used for moderate support; ensure a snug fit over the nose and mouth.
• Non-Rebreather Mask (10-15 LPM): Used for high-concentration oxygen; ensure the reservoir bag is inflated prior to placement.
• Humidification: Add distilled water to the humidifier bottle if the flow rate exceeds 4 LPM to prevent mucosal drying.

3. Administration Procedure

• Hand Hygiene: Perform aseptic hand washing or apply alcohol-based sanitizer.
• Connect Equipment: Attach tubing to the flow meter/outlet.
• Set Flow Rate: Adjust the dial to the prescribed liters per minute (LPM).
• Verify Flow: Ensure oxygen is flowing through the device before placing it on the patient.
• Application: Secure the device onto the patient, adjusting straps for comfort while maintaining a therapeutic seal.
• Patient Comfort: Pad areas behind the ears to prevent skin breakdown.

4. Monitoring and Documentation

• SpO2 Monitoring: Observe pulse oximetry readings continuously or as per facility protocol.
• Respiratory Assessment: Monitor for improvements in work of breathing and mental status.
• Documentation: Record the start time, device used, flow rate, patient tolerance, and pre/post-intervention vital signs in the Electronic Health Record (EHR).
• Re-evaluation: Reassess the patient within 15–30 minutes to confirm stabilization.

Pro Tips & Pitfalls

• Pitfall - The Inflated Bag: Never place a non-rebreather mask on a patient without pre-inflating the reservoir bag; otherwise, the patient will not receive the intended high concentration.
• Pro Tip - Skin Integrity: For patients on long-term oxygen, rotate device straps and use foam dressings behind the ears to prevent pressure ulcers.
• Pitfall - Over-oxygenation: Avoid administering 100% oxygen indefinitely unless medically necessary, as it can lead to absorption atelectasis and oxygen toxicity.
• Pro Tip - Troubleshooting: If the patient's SpO2 drops despite high-flow therapy, check for tubing disconnections and verify that the oxygen tank has sufficient volume remaining.

FAQ

1. At what flow rate should I consider adding humidification? Humidification is generally recommended for flow rates exceeding 4 LPM to prevent drying of the nasal and oral mucosa, which can lead to epistaxis or discomfort.

2. How do I know if the patient is receiving enough oxygen? Assess the patient’s clinical presentation (reduced respiratory rate, improved skin color, decreased anxiety) in addition to SpO2 readings (typically target >92% unless the patient has a history of COPD).

3. What should I do if the oxygen tank gauge is low? Immediately secure an auxiliary oxygen source (backup tank or wall outlet) before disconnecting the current supply to ensure the patient does not experience a lapse in therapy.
