(documentation Thoracentesis EnglishLanguage "Thoracentesis, also known as thoracocentesis pleural tap, needle thoracostomy, or needle decompression (often used term), is an invasive medical procedure to remove Fluid or Air from the pleural space for diagnostic or therapeutic purposes. A cannula, or hollow needle, is carefully introduced into the thorax, generally after administration of local Anesthesia. The recommended location varies depending upon the source. Some sources recommend the midaxillary line, in the eighth, ninth, or tenth intercostal space. Whenever possible, the procedure should be performed under ultrasound guidance, which has shown to reduce complications. Tension Pneumothorax is a medical emergency that requires needle decompression before a chest tube is placed.[from Wikipedia]")	Medicine.kif 858-867	Needle decompression is a subclass of removing
