An integrated chest evacuation tube that is specifically configured for being a closed system when inserted and retained inside of a chest cavity provides enhanced benefits over the state of the art. The integrated chest evacuation tube generally includes a valve that is made up of a hollow ...
The thinner membranous part of the interventricular septum is formed from the lowest aspect of the spiral valve (neural crest cells), which divides the truncus arteriosus into the aorta and pulmonary trunk. The muscles of the four chambers and the four valves are attached to, and supported by,...

The pulmonary trunk or main pulmonary artery originates in the mediastinum at the pulmonary valve and extends cranially and slightly to the left for 4 to 5 cm before bifurcating within the pericardium into the shorter left and longer right pulmonary arteries ( Fig. 1.6 ). The left pulmonary...
A collateral ventilation bypass system with chest tube evacuation device may be utilized in combination to removed trapped air from the lungs. With the chest tube evacuation device, any air trapped in the pleural space may be evacuated through the bypass system to prevent a pneumothorax.;In one ...
(seeFig. 29.3). Lymph nodes can also impinge on the airway, causing a narrowing of the airway that is notable on imaging (Fig. 29.13), with distal hyperinflation from a ball-valve effect (seeFig. 29.6A), or they may cause secondary collapse of the distal segment, manifesting as a fan...
The location of the primary-foramen ASD was close to the mitral and tricuspid valve annulus, so tricuspid and mitral regurgitations may occur, resulting in the enlargement of the left heart circulation. In addition, if a larger ASD was not treated for a long time, pulmonary vascular resistance...
Mitral valve prolapse.It happenswhen a valve in the heart fails to close properly. A variety of symptoms have been associated with mitral valve prolapse, including chest pain, palpitations, and dizziness, but it can also have no symptoms, especially if the prolapse is mild. ...
52.An apparatus for assisting a rescuer in performing chest compressions during CPR on a victim, the apparatus comprising:a pad or other structure configured to be applied to the chest near or at the location at which the rescuer applies force to produce the chest compressions,at least one acc...
(e.g. a tube extending into the mouth or nose). In FIG. 2, an outlet valve220is provided, which is sensitive to the flow of pressured gas through inlet72, to open when the inflow stops. The upward movement of the piston expels reduced-pressure oxygen, which can be flowed to the ...
