Like a regular pneumothorax but artificial valve in visceral pleura (one on the inside) means air goes into the space but not back into the lung.
Usually caused by a rupture of the pleura and can be sponatneous.
- Lung - asthma, TB, COPD, pneumonia, cancer, abscess, CF, fibrosis
- Non-lung - connective tissue: sarcoidosis; trauma: both iatrogenic and non-iatrogenic
Having a pneumothorax, being a young thin man (like me, baby!).
- Respiratory - shortness of breath, pleuritic chest pain, diminished breath sounds and hyperesonant over affected area, reduced chest expansion
- Cardiac - tachycardia, hypotension
- Neck - deviated trachea, distended neck veins
If you suspect one DO SOMETHING STRAIGHTAWAY! GO STRAIGHT TO MANAGEMENT!
Insert a chest drain:
- Use a large-bore (14-16G) needle and syringe
- Fill slightly with 0.9% saline
- Insert into 2nd intercostal space, mid-clavicular line
- Remove plunger - air will bubble through saline and you'll be able tell it's been successful
After this has been done, replace the syringe with a chest drain.
