What is the pressure of the lung wedge?

The

pulmonary wedge pressure (PWP) is a diagnostic and therapeutic medical tool for measuring using a wedge balloon in the lung catheter and inflated in the pulmonary artery. After inflation, the balloon can measure the diastolic pressure of the left ventricle. This tool can measure significant differences between artery and venous pressures that can be caused by arterial venous malformations (AVMS). PWP can be used during surgery and for the treatment of many serious and critical diseases.

Some of the diagnostic uses of lung wedge pressure are for shock conditions, valve diseases, pulmonary embolism and heart tamponade, which is a collection of blood in the pericardium causing compression. It can also be used for diagnosis of serious burns, multiple organs failure and idiopathic lung hypertension. The lung Edemas, which are above certain levels, is a condition threatening life and through a periodic capillary wedge of fading eSeras, the physician can effectively adapt the use of diuretics. In addition, respiratory patterns PAccents with heart failure to monitor carefully to see if the usual shallow breathing deteriorates their conditions, which requires further treatment to prevent heart failure.

The pressures are measured by inserting a catheter with a balloon into peripheral veins and through these veins entering the right atrium of the heart and from there to the pulmonary arteries. Measurement of systolic and diastolic pressures gives the right values ​​of atrial pressure and, as the balloon blows back, the left atrial pressure is estimated. The catheter, also known as the swan-ganz catheter, is often governed by a fluoroscope.

lung wedge pressure measures lung water changes, which may indicate pulmonary constructions in patients with acute respiratory districts ESS (ARDS) and hypoxemia. The use evaluates the pulmonary wedge pressure in patients undergoing procedures by the doctor in the calculation of cardiac output, indicating how much function can be affected. HeartCE and hemodynamic values ​​of anesthetized patients can instruct an anaesthesiologist who monitors the patient's conditions to indicate that therapeutic interventions are necessary.

In the evaluation of shock states, the lung wedge pressure can be read to determine whether tachycardia or hypotension are present if there are insufficient ventricular fillings or whether severe depression in cardiac procedure has inserted the patient in a state of cardiogenic shock. In the event of a mitral valve leakage, often caused by congenital heart conditions or rheumatic damage to the fever on the mitral valve, PWP may observe the progress that signal cracked papillary muscles. In cases of septic shock, which is the most common form of intensive care unit (ICU), the United States, reading PWP, can detect low compliance pressures that inform about deep peripheral vasodilations that rob organs of blood.

Risks and possible complications from the use of the lung catheter show that the most common and serious complications Je rupture of the pulmonary artery. Of course, the operator's skill and patient condition affect any complications that could occur. A common complication when inserting the lung catheter is the heart of the arrhythmia.
