Where do you place chest tube?

The tube around your lung is placed between your ribs and into the space between the inner lining and the outer lining of your chest cavity. This is called the pleural space. It is done to allow your lungs to fully expand.

Which anatomical position is a chest drain usually inserted and why?

The drain should be inserted just above the rib. Any other placement should be discussed with a senior clinician eg. in the presence of an apical pneumothorax, placement of a chest tube in the 2nd intercostal space should be considered. A specific position may also be required for a loculated effusion.

How do you check placement of a chest tube?

Your doctor may use computed tomography (CT), ultrasound or fluoroscopy to help guide placement of the chest tube. The doctor may take x-rays after the procedure to check the placement of the chest tube. The chest tube is like a catheter. The size of the tube placed varies depending on the reason for the procedure.

How does Pleur Evac work?

Both the wet suction and dry suction series of Pleur-evac have a positive pressure relief valve that opens with increases in positive pressure, preventing pressure accumulation (figure 15). Normally, air exits through the suction port.

What is a Pleur Evac?

The Pleur-EvacĀ® Infant Chest Drainage unit with dry suction control and water seal is a sterile, single use drainage system intended for post-operative patient care. The fluid path is non-pyrogenic.

Should there be bubbling in the water seal chamber?

Air bubbling through the water seal chamber intermittently is normal when the patient coughs or exhales, but if there is continuous air bubbling in the chamber, it can indicate a leak that should be evaluated.
