Surgical apparatus and devices are provided for performing closed chest cardiac surgery. A multi-lumen substantially tubular channel is inserted transabdominally to gain access to either the pleural or mediastinal space for the purposes of achieving less invasive cardiac surgery, more particularly complete revascularization CABG surgery directly on the beating heart.

ABG (arterial blood gas): The sampling of the blood levels of oxygen and carbon dioxide within the arteries, as opposed to the levels of oxygen and carbon dioxide in venous blood. As a result, blood passes through the lungs without receiving enough oxygen. Causes Pulmonary arteriovenous fistulas are usually the result of a genetic disease that causes the blood vessels of the lung to develop.

If the pleural layers are ruptured, for example by a spontaneous rupture of the membrane or by a stab wound, air is sucked into the intrapleural space creating a real air-containing space between the lungs and chest wall - a pneumothorax. This abolishes the negative intrapleural pressure and the lung in the affected area will collapse. Gas exchange will be seriously impaired because movement.The invention relates to a lung simulator apparatus, as well as to a method to ventilate a lung simulator with a ventilator. The lung simulator apparatus comprises an air chamber with a variable volume for an exchangeable gas, which air chamber is connected in parallel with two air conduits, and a gas exchange element for injecting a tracer gas into the air chamber, wherein the volumes of the.This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single.


PNX is characterized by the presence of air or gas in the pleural space. When the parietal or visceral pleura is breached the pleural cavity is exposed to a positive atmospheric pressure, the air will enter this space and the lung will collapse. Any condition that impairs the structural integrity of the pleural membranes can produce a PNX: It can be classified in three categories: Spontaneous.The pleural cavity also known as the pleural space, is the thin fluid-filled space between the two pulmonary pleurae (known as visceral and parietal) of each lung.A pleura is a serous membrane which folds back onto itself to form a two-layered membranous pleural sac. The outer pleura (parietal pleura) is attached to the chest wall, but is separated from it by the endothoracic fascia.

The pleural cavity is the space that lies between the pleura, the two thin membranes that line and surround the lungs.The pleural cavity contains a small amount of liquid known as pleural fluid, which provides lubrication as the lungs expand and contract during respiration.When increased fluid occupies this space, it is referred to as a pleural effusion and can severely restrict breathing.

When the pleural cavity is opened, blood and fluid can enter and compress the adjacent lung. In patients undergoing coronary revascularization, dissection of the left internal mammary artery may require entry into the left pleural space. All these factors account for the 60% to 70% preponderance of left lower lobe atelectasis after CPB.

Overview The pleura is the membrane that lines the thoracic (chest) cavity and covers the lungs. It is like a large sheet of tissue that wraps around the outside of the lungs and lines the inside of the chest cavity. There are several types of pleural diseases, including: Pleurisy - an infection of the pleural cavity Pleural effusion - the buildup of pleural fluid in the.

In one such embodiment, gas pockets are vented to inhibit excessive back-pressure or suction on an organ, vessel or cavity being drained. In another such embodiment, loops in the tubes are avoided by using a mechanical template in the form of a groove or peg assembly to thread the slack in the drainage tube to generate a monotonic gradient. In another embodiment, such as for active drainage.

The pleura and pleural spaces are only clearly visible when abnormal. Some diseases, such as mesothelioma, cause pleural thickening.Other pleural diseases lead to fluid accumulation (pleural effusion) or air gathering in the pleural spaces (pneumothorax).

Pleural effusion is the abnormal accumulation of fluid in the pleural space (the area between the two layers of the thin membrane that covers the lungs). Fluid can accumulate in the pleural space as a result of a large number of disorders, including infections, tumors, injuries, heart, kidney, or liver failure, blood clots in the lung blood vessels (pulmonary emboli), and drugs.

Gas exchange in the lungs We need to get oxygen from the air into the blood, and we need to remove waste carbon dioxide from the blood into the air. Moving gases like this is called gas exchange.
