Med Surg Respiratory: Part 2
Med Surg Respiratory: Part 2 – Assess, Analyze, Intervene! 🩺💨
Ready for another dose of Med Surg Respiratory knowledge? This time, we’re diving into Respiratory Assessments, ABGs, and those critical conditions you must master! Let’s go!
🌬️ Respiratory Assessment
Your first line of defense is a solid assessment!
👂 What to look for:
• Rate: Normal (12–20 bpm). Too fast = Tachypnea, Too slow = Bradypnea.
• Effort: Use of accessory muscles, nasal flaring, or tripod positioning.
• Sounds: Crackles = fluid, Wheezes = narrowed airways, Stridor = obstruction.
• O2 Saturation: Should be ≥ 95% unless chronic respiratory conditions are present.
✨ Pro Tip: Always start with inspection, then palpate, percuss, and auscultate!
🩸 Arterial Blood Gases (ABGs)
Your key to understanding acid-base imbalances!
• pH: 7.35–7.45
• PaCO2: 35–45 mmHg
• HCO3: 22–26 mEq/L
✨ Quick Guide:
1️⃣ Low pH + High PaCO2 = Respiratory Acidosis (e.g., COPD, hypoventilation).
2️⃣ High pH + Low PaCO2 = Respiratory Alkalosis (e.g., anxiety, hyperventilation).
3️⃣ Low pH + Low HCO3 = Metabolic Acidosis (e.g., DKA, renal failure).
4️⃣ High pH + High HCO3 = Metabolic Alkalosis (e.g., vomiting, antacid overuse).
💡 Pro Tip: Use the ROME method—Respiratory Opposite, Metabolic Equal—to interpret imbalances!
🚨 Acute Respiratory Distress Syndrome (ARDS)
A life-threatening condition where the lungs can’t oxygenate properly.
🛑 Causes: Sepsis, trauma, aspiration, pneumonia.
🛑 Symptoms: Severe hypoxemia that doesn’t improve with oxygen, crackles, tachypnea.
✨ Nursing Priorities:
• Mechanical ventilation with PEEP (Positive End-Expiratory Pressure).
• Frequent ABG monitoring.
• Positioning: Prone helps improve oxygenation.
💨 Chest Tubes
Chest tubes = Lifesaving for pneumothorax, hemothorax, or pleural effusion.
✨ Key Nursing Interventions:
1️⃣ Monitor Drainage: Report >100 mL/hr or bright red output.
2️⃣ Assess for Air Leaks: Continuous bubbling in the water seal chamber = leak!
3️⃣ Keep Emergency Equipment Nearby: Sterile gauze, clamps, and a chest tube system.
4️⃣ Patient Positioning: Semi-Fowler’s to promote drainage and lung expansion.
💡 Pro Tip: If the chest tube becomes dislodged, cover the site with sterile gauze and call the provider immediately.
✨ Nursing Intervention Focus
Always prioritize oxygenation and ventilation:
• Sit patients upright.
• Use incentive spirometry.
• Monitor ABGs and respiratory status closely.
Mastering these concepts will help you breathe easier during exams and clinicals!

Understanding respiratory conditions is critical for nursing professionals. One key condition is Pulmonary Embolism (PE), which occurs when a blood clot obstructs a pulmonary artery, often originating from deep vein thrombosis (DVT). Symptoms include sudden shortness of breath, sharp chest pain, and tachycardia. Diagnostic tests such as a pulmonary angiogram or CT pulmonary angiography are essential for confirmation. Treatment typically involves anticoagulants to prevent further clotting and may require thrombolytics to dissolve existing clots. Acute Respiratory Distress Syndrome (ARDS) is another serious condition characterized by fluid accumulation in the alveoli, drastically impairing oxygen exchange. It can result from various causes, including trauma, pneumonia, and sepsis. The nursing management for ARDS includes maintaining patent airways, administering supplemental oxygen, and positioning strategies like prone ventilation to enhance oxygenation. Close monitoring of clinical signs and ABG levels is crucial for managing these critical conditions effectively. Chest tubes are vital in cases of pneumothorax and pleural effusion, with key nursing interventions like monitoring drainage and ensuring proper ventilation techniques being essential for optimal patient care. By mastering these concepts, you'll be better prepared for both exams and real-life clinical scenarios in respiratory nursing.
