If the arm electrodes are reversed, lead I changes polarity, causing lead II and lead III to switch. If the right arm electrode is reversed with the leg's electrode, lead II changes polarity, causing lead I to become lead III, and vice versa. Reversal of the left arm and leg causes a change in polarity of lead III and switching of leads I and ...
Pulmonary laceration is a common result of penetrating trauma but may also be caused by blunt trauma; broken ribs may perforate the lung, or the tissue may be torn due to shearing forces [5] that result from different rates of acceleration or deceleration of different tissues of the lung. [6]
The Vector templates below can be used to derive images with, for example, Inkscape. This is the method with the greatest potential. This is the method with the greatest potential. See Human body diagrams/Inkscape tutorial for a basic description in how to do this.
The azygos vein transports deoxygenated blood from the posterior walls of the thorax and abdomen into the superior vena cava.. It is formed by the union of the ascending lumbar veins with the right subcostal veins at the level of the 12th thoracic vertebra, ascending to the right of the descending aorta and thoracic duct, passing behind the right crus of diaphragm, anterior to the vertebral ...
The V 5 ECG lead is placed on the anterior axillary line, horizontally even with V 4. The midaxillary line is a coronal line on the torso between the anterior and posterior axillary lines. It is a landmark used in thoracentesis , [ 2 ] and the V6 electrode of the 10 electrode ECG.
The alveoli. Pulmonary contusion and laceration are injuries to the lung tissue. Pulmonary laceration, in which lung tissue is torn or cut, differs from pulmonary contusion in that the former involves disruption of the macroscopic architecture of the lung, [1] while the latter does not. [2]
Paradoxical Respiration: during inspiration, the flail (abnormally mobile) segments of ribs are pulled inside the chest wall while during expiration the ribs are pushed out. Tuberculosis of the lung is a common disease in certain parts of the world. A complete course of treatment must be taken under the guidance of a physician.
Axial lower chest CT scan showing bowel herniation due to left diaphragmatic rupture. A CT scan has an increased accuracy of diagnosis over X-ray, [7] but no specific findings on a CT scan exist to establish a diagnosis. [9] The free edge of a ruptured diaphragm may curl and become perpendicular to the chest wall, a sign known as a dangling ...
