Needle decompression is an emergency procedure used to relieve pressure caused by a suspected tension pneumothorax. When air becomes trapped in the pleural space, increasing pressure can rapidly impair both respiratory and circulatory function.
Tension pneumothorax is a clinical diagnosis. Do not delay treatment when a patient is exhibiting signs of respiratory compromise and deterioration.
Assessment findings that may support the need for decompression include:
- Severe respiratory distress
- Unilateral diminished or absent breath sounds
- Increasing work of breathing
- Hypoxia
- Signs of shock
- Progressive deterioration following chest trauma
Common decompression sites include:
- 4th or 5th Intercostal Space, Anterior Mid-Axillary Line — affected side (Preferred)
- 2nd Intercostal Space, Midclavicular Line — affected side (Alternate)
Follow local protocols when selecting decompression sites. Proper landmark identification is critical to successful decompression and reducing complications.
Following decompression, reassess:
- Breath sounds
- Respiratory status
- SpO2
- Signs of continued deterioration
Improvement following decompression supports the diagnosis. Ongoing deterioration may indicate incomplete decompression, contralateral tension pneumothorax, or an alternate diagnosis.
Remember: This is a pressure problem, When its cloesd → Open it, decompress when indicated, and reassess the patient.
