Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, a 68-year-old with a 40-pack-year smoking history and severe COPD, was admitted two days ago for increased shortness of breath. His condition has worsened. He is now difficult to arouse, his respiratory rate is 10 and shallow, and his SpO2 is 85% on 2L nasal cannula. The rapid response team is called.
Nursing Intervention Strategy:- 1Immediate Assessment (ABCs)Stimulate the patient. Check for a patent airway. Auscultate breath sounds (likely diminished). Note accessory muscle use.
- 2Call for Help & Prepare for IntubationAlert the provider of the patient's decline. Have the bag-mask valve (BMV) and suction ready at the bedside. The provider will likely order rapid sequence intubation (RSI).
- 3Assist with VentilationWhile preparing for intubation, you may need to assist ventilations with the BMV using 100% oxygen, as ordered, to temporarily support oxygenation and ventilation.
- 4Post-Intubation CareOnce mechanically ventilated, secure the endotracheal tube, confirm placement with capnography and chest X-ray, and set ventilator parameters per order (often a lung-protective strategy). Monitor for complications like pneumothorax.
Patient Safety and Precautions:
• Oxygen Caution: If the patient is still breathing spontaneously before intubation, do not arbitrarily increase oxygen flow. Use the BMV with 100% O2 only when actively assisting breaths or as directed.
• Sedation & Paralytics: Patients on mechanical ventilation will require sedation and possibly paralytics. Monitor closely for hemodynamic instability.
• Communication: Once stabilized, explain all procedures to the family. A patient with COPD exacerbation requiring intubation has a significant mortality risk.
Nursing Procedure & Medication Flow
Assisting with Bag-Mask Ventilation (BMV):
1. Position: Use the "sniffing" position (if no cervical spine injury). Use an oropharyngeal airway if needed.
2. Seal: Use the E-C clamp technique to create a tight seal.
3. Ventilate: Squeeze the bag smoothly over 1 second, observing for chest rise. Ventilate at a rate of 10-12 breaths/minute (every 5-6 seconds). Do not over-ventilate.
4. Assess: Continuously check for effective ventilation (chest rise, SpO2 improvement, heart rate response).
Mechanical Ventilation Monitoring:
• Ventilator Settings: Note FiO2, mode (e.g., AC/VC), rate, tidal volume (often 6-8 mL/kg ideal body weight), and PEEP.
• Patient Response: Monitor ABGs, SpO2, end-tidal CO2, breath sounds, and work of breathing.
• Complications: Watch for ventilator-associated pneumonia (VAP), barotrauma, and ventilator dyssynchrony.
A Word from Your Senior Nurse
"Managing a COPD patient in respiratory failure is one of the most high-stakes situations you'll face. Your ability to connect the dots between the ABG, the patient's mental status, and their breathing pattern is what saves lives. Never ignore a drowsy COPD patient with slow, shallow breathing—it's a red flag for CO2 narcosis and impending arrest. In clinicals and on the NCLEX, always ask yourself: 'Is the patient effectively moving air?' If the answer is no, your next thought must be 'How do I support or take over that function?' That's the essence of priority-setting in nursing."
