📒 The 1-minute cheat sheet
✅ Do
Sit upright, seal lips on mouthpiece
Inhale slow + deep, hold 3-5 sec
10 breaths/hr while awake
🎓 Teach
Splint incision w/ pillow, then cough
Goal = keep float/piston up = expansion
📌 Avoid
Don't exhale into device
No fast shallow breaths
🚩 Report
Dizziness → pause, slow rate
↓ volumes, fever → pneumonia risk
📚 Incentive Spirometry — 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.
An incentive spirometer is a handheld device that encourages slow, deep breaths to expand the lungs, prevent atelectasis, and reduce postoperative pneumonia. It is especially important after surgery, prolonged bed rest, or with reduced mobility. Key principle: a slow, sustained, deep inhalation, not a fast or forceful breath.
🔑
Key points
Understand these first
It works by promoting sustained maximal inspiration to open alveoli and prevent atelectasis.
The client sits upright (high-Fowler's) for best lung expansion.
Technique: exhale normally, seal lips tightly around the mouthpiece, inhale slowly and deeply, hold 3 to 5 seconds, then exhale.
Typical use is about 10 breaths every 1 to 2 hours while awake, especially post-op.
Coughing after using the device helps clear loosened secretions.
It is a key prevention measure for postoperative pneumonia and atelectasis.
✅
Nursing priorities
What to do, in order
Position the client upright and pre-medicate for pain so deep breathing is effective (splint incision with a pillow).
Demonstrate the technique: slow, deep, sustained inhalation with a 3- to 5-second hold.
Encourage use about 10 times per hour while awake.
Have the client cough afterward to clear secretions and assess lung sounds.
Monitor for improvement in breath sounds and the volume achieved over time.
🚩
Red flags — report now
Escalate immediately
Worsening shortness of breath, decreasing SpO2, fever, or new crackles/diminished breath sounds may signal atelectasis or pneumonia; report.
Dizziness or lightheadedness during use indicates breaths are too rapid; have the client slow down and rest.
Never substitute fast, shallow breaths for the slow sustained inhalation the device requires.

Patient teaching
What patients must know
Inhale slowly and deeply, hold the breath 3 to 5 seconds, then exhale; do not breathe out into the device.
Use it about 10 times every hour while awake and cough afterward.
Splint your incision with a pillow to make deep breathing and coughing more comfortable.
❓ Incentive Spirometry: NCLEX FAQs
What are the priority nursing interventions for Incentive Spirometry?

Demonstrate the technique: slow, deep, sustained inhalation with a 3- to 5-second hold. Encourage use about 10 times per hour while awake. Have the client cough afterward to clear secretions and assess lung sounds.
What are the warning signs of Incentive Spirometry a nurse must report?
Worsening shortness of breath, decreasing SpO2, fever, or new crackles/diminished breath sounds may signal atelectasis or pneumonia; report. Dizziness or lightheadedness during use indicates breaths are too rapid; have the client slow down and rest. Never substitute fast, shallow breaths for the slow sustained inhalation the device requires.
