A pleural vent is a medical device that is used to treat a pneumothorax. This page will explain what a pleural vent is, why it is used and how it is inserted.
A pneumothorax occurs when air gets trapped in the space between the lung and the chest wall (the pleural space). The air gets there either from a defect on the surface of lung or through the chest wall. The air can squash the underlying lung and cause it to collapse.
You may experience some or all of the following symptoms; breathlessness, cough, or a sharp, stabbing pain on one side of the chest, which may be worse when breathing in.
There are different ways to treat a pneumothorax depending on the cause, how large it is and how severe your symptoms are. This includes conservative management (observation only), pleural aspiration and an intercostal chest drain. Your doctor will explain the benefits and risks of these options to you in more detail.
Sometimes, we can use a pleural vent instead of an aspiration or a chest drain.
A pleural vent is a small medical device. It consists of a small tube connected to a one-way valve inside a chamber. The tube sits inside the chest and the chamber sits on the front of the chest.
The pleural vent allows air to escape from the pleural space through the device to help the lung reinflate.
Unlike a chest drain, you can usually go home with a pleural vent in place and do not have to stay in hospital. The pleural vent stays in for a few days until the pneumothorax has healed.
The pleural vent is inserted in hospital by a doctor who will talk to you about the benefits and risks of the procedure and ask you to sign a consent form.
You must tell the doctor if you take any medications that thin your blood, such as warfarin, apixaban, rivaroxaban or clopidogrel. These medications can increase the risk of bleeding and may need to be stopped before the procedure.
The procedure takes about 15 minutes, and you will be placed into a comfortable position on your back on a couch. Then:
A pleural vent is simple and quick to insert with local anaesthetic, it allows continuous drainage of air from the pleural space, unlike an aspiration, and you can walk around as normal. If you feel comfortable, you may be able to go home with the pleural vent in place.
Inserting a Pleural Vent is a routine and safe procedure. However, as with any medical procedure, there are potential risks:
Call 999 or attend the Accident and Emergency Department immediately if:
Do check that the blue disk at the top of the Pleural Vent moves up and down when you breathe.
Do tell the nurses or doctors, using the contacts below, if the disk stops moving. This may mean the pneumothorax has resolved.
Do avoid heavy lifting, straining or vigorous exercise as this may displace the device or make the pneumothorax worse.
Do not take a bath, go swimming, or immerse the device in water. This can damage the device or dressing and increases the risk of infection.
Do not remove the device yourself.
Sometimes, fluid can come out of the chest in addition to air. The Pleural Vent can collect a small amount of this fluid in the chamber but may need to be drained periodically. If you notice the fluid collection chamber is full, please contact us using the numbers below.
The pleural vent must only be removed by a trained healthcare professional. Any dressings or stitches will be removed and then the device is pulled out. A simple dressing is placed over the area. This only takes a couple of seconds and is not painful. After it is removed, a chest X-ray will be repeated.
We will remove the pleural vent in the Pleural Clinic when the pneumothorax is resolved.
