📚 Postoperative Atelectasis Prevention — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Atelectasis is collapse of alveoli, common after surgery due to shallow breathing from pain, anesthesia, and immobility. It reduces gas exchange and can progress to pneumonia. Prevention centers on deep breathing, early mobility, and lung expansion. It is usually the cause of a low-grade fever in the first 24-48 hours after surgery.
🔑
Key points
Understand these first
Anesthesia, splinting from pain, and immobility lead to shallow respirations and alveolar collapse.
Incentive spirometry promotes deep sustained inhalation that re-expands alveoli.
Early signs include decreased breath sounds, crackles, low-grade fever, and a mild fall in oxygen saturation.
Early ambulation is one of the most effective preventive measures.
Untreated atelectasis predisposes the patient to postoperative pneumonia.
Adequate pain control allows deeper breathing and effective coughing.
✅
Nursing priorities
What to do, in order
Have the patient use the incentive spirometer about 10 times every hour while awake.
Coach deep breathing and coughing, and splint the incision with a pillow to ease pain.
Encourage early and progressive ambulation and frequent repositioning.
Manage pain proactively so the patient can breathe deeply and cough effectively.
Auscultate lung sounds and monitor oxygen saturation each shift.
What are the priority nursing interventions for Postoperative Atelectasis Prevention?
Have the patient use the incentive spirometer about 10 times every hour while awake. Coach deep breathing and coughing, and splint the incision with a pillow to ease pain. Encourage early and progressive ambulation and frequent repositioning. Manage pain proactively so the patient can breathe deeply and cough effectively.
What are the warning signs of Postoperative Atelectasis Prevention a nurse must report?
Report worsening dyspnea, persistent low oxygen saturation, or diminished breath sounds. A fever that persists or rises beyond 48 hours may signal pneumonia rather than simple atelectasis. Never skip lung-expansion measures because the patient says coughing hurts; treat pain instead.
What do I need to know about Postoperative Atelectasis Prevention for the NCLEX?
Anesthesia, splinting from pain, and immobility lead to shallow respirations and alveolar collapse. Incentive spirometry promotes deep sustained inhalation that re-expands alveoli. Early signs include decreased breath sounds, crackles, low-grade fever, and a mild fall in oxygen saturation. Early ambulation is one of the most effective preventive measures.
What patient teaching is important for Postoperative Atelectasis Prevention?
Use the incentive spirometer hourly: inhale slowly and deeply, hold, then relax. Splint your incision with a pillow when coughing or deep breathing to reduce pain. Get up and walk as soon as you are cleared, because moving helps your lungs stay open.
