iatrogenic pneumothorax

pneumothorax caused by a medical procedure, most often central venous catheter insertion, thoracentesis, or transbronchial and transthoracic lung biopsy.

iatrogenic pneumothorax

a condition in which air or gas is present in the pleural cavity as a result of mechanical ventilation, tracheostomy tube placement, or other therapeutic intervention.

(ī-at'rō-jen'ik nū'mō-thōr'aks)
Pneumothorax caused by a medical procedure, most often central venous catheter insertion, thoracentesis, or transbronchial and transthoracic lung biopsy.

pneumothorax

entry of air into the pleural cavity in sufficient quantity to cause collapse of the lung and consequent respiratory embarrassment. If it is unilateral there is a mediastinal shift with displacement of the heart to the other side of the chest. Breath sounds are absent from the affected side.

closed pneumothorax
air leaks from a discontinuity in the lung into the pleural cavity.
false pneumothorax
artifactual increased radiolucency of the thorax resembling free air in the pleural cavity.
iatrogenic pneumothorax
may occur following intrathoracic surgery or in association with procedures which involve entry into the pleural cavity, such as thoracentesis or placement of a chest drain.
open pneumothorax
caused by an open wound in the chest wall.
spontaneous pneumothorax
due to an unknown cause.
tension pneumothorax
a particularly dangerous form of pneumothorax that occurs when air escapes into the pleural cavity from a bronchus but cannot regain entry into the bronchus. As a result, continuously increasing air pressure in the pleural cavity causes progressive collapse of the lung tissue. If not relieved, it can lead to lung collapse and mediastinal shift.

The rates of six key quality improvement focus areas (metabolic derangements, post-operative respiratory failure, decubitus ulcer, post-operative pulmonary embolus (PE) or deep vein thrombosis (DVT), and hospital-acquired infections) worsened on average by 20 percent or more over four years (2000 through 2003), while another six PSIs (death in low mortality DRGs, failure to rescue, iatrogenic pneumothorax, post-operative hip fracture, post-operative hemorrhage or hematoma, and post-operative wound dehiscence) improved on average by less than 10 percent.
