Patients with cirrhosis are frequently hypoalbuminemic, which leads to a chronic state of decreased plasma oncotic pressure. This imbalance between the hydrostatic and oncotic forces across the pleural membrane results in an effusion.

The most common cause of a transudate is congestive heart failure (CHF). The increased pulmonary capillary hydrostatic pressure in patients with CHF results in a net flow of fluid into the pulmonary interstitium.

Transudates are caused by either an increase in intravascular hydrostatic pressure or a decrease in intravascular oncotic pressure. This generates an increased flow of fluid into the pleural space across noninjured capillary beds.

The volume of air that moves in and out of a patient's lungs per minute is termed minute volume (E). E is the product of tidal volume (VT) and respiratory frequency or rate (f): E = VT x f.

Major bleeding is one of the most feared complications of tracheostomy. Sources of bleeding include the thyroid vessels, anterior jugular veins, brachiocephalic (innominate) artery, carotid artery and aortic arch.

Tracheomalacia is weakening of the tracheal cartilage from pressure necrosis and results in luminal widening. A loose tracheostomy tube with excessive mobility can cause air leaks or tracheal collapse.

Tracheal stenosis and tracheomalacia are late complications of a tracheostomy, often occurring weeks-months after decannulation. Clinically significant stenosis has been estimated to develop in 10% of all tracheostomy patients.

Tracheostomy tubes do not fracture frequently. When fractures do occur, they are most often located at the juncture of the flange and the tube connection. A fractured tube fragment may migrate inferiorly and obstruct the tracheal lumen.

Subcutaneous air, crepitus or distortion of anterior neck landmarks may indicate placement of the tracheostomy tube into a false passage. Absence of a waveform on capnography confirms misplacement of the tracheostomy tube.
