Thoracentesis Nursing Priority: Respiratory Monitoring & Complication Detection

During thoracentesis, the single most critical nursing intervention is continuous assessment of respiratory status to detect life-threatening complications early.

Key Monitoring Parameters

• Respiratory Rate, Depth & Pattern: Tachypnea, shallow breathing, paradoxical movement.
• Oxygen Saturation (Continuous Pulse Oximetry): Target ≥92%; drop >4% from baseline warrants intervention.
• Breath Sounds (q15min & PRN): Diminished/absent unilaterally suggests pneumothorax; crackles suggest re-expansion pulmonary edema.
• Symmetry of Chest Expansion: Asymmetry indicates pneumothorax or large effusion recurrence.
• Patient-Reported Symptoms: Dyspnea, chest pain/tightness, cough, dizziness, shoulder pain (referred diaphragmatic irritation).
• Vital Signs: Hypotension, tachycardia, hypoxia — signs of vasovagal response, hemorrhage, or tension pneumothorax.

Immediate Actions for Respiratory Deterioration

1. STOP the procedure.
2. Apply supplemental O2 (high-flow nasal cannula or non-rebreather).
3. Elevate HOB to 45–90°.
4. Prepare for emergent chest tube insertion if tension pneumothorax suspected (tracheal deviation, hemodynamic collapse).
5. Notify provider STAT; anticipate chest X-ray.

Post-Procedure Monitoring

Continue q15min x1hr, q30min x2hr, then q1hr x4hr. Obtain post-procedure CXR per protocol (typically 1–3 hrs post) to confirm lung re-expansion and rule out occult pneumothorax.
