The primary site of infection in the lungs, known as the Ghon focus, is generally located in either the upper part of the lower lobe, or the lower part of the upper lobe. [13] Tuberculosis of the lungs may also occur via infection from the blood stream. This is known as a Simon focus and is typically found in the top of the lung. [91]
Small-cell lung carcinoma (SCLC) has long been divided into two clinicopathological stages, termed limited stage (LS) and extensive stage (ES). [8] The stage is generally determined by the presence or absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy ...
That is, in whispered pectoriloquy, the repeated words are whispered at low volume, and in bronchophony, they are spoken at normal volume. The clinical observation being determined is whether or not an increase in volume is heard at the clinician's stethoscope over the lung field being auscultated which would indicate lung consolidation.
The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surround the lungs. The inner (visceral pleura) covers the lungs and the outer (parietal pleura) lines the inner surface of the chest wall. This ...
Typically, an area of white lung is seen on a standard X-ray. [5] Consolidated tissue is more radio-opaque than normally aerated lung parenchyma, so that it is clearly demonstrable in radiography and on CT scans. Consolidation is often a middle-to-late stage feature/complication in pulmonary infections.
The lungs stretch from close to the backbone in the rib cage to the front of the chest and downwards from the lower part of the trachea to the diaphragm. [1] The left lung shares space with the heart, and has an indentation in its border called the cardiac notch of the left lung to accommodate this.
A small amount of applied PEEP (4 to 5 cmH 2 O) is used in most mechanically ventilated patients to mitigate end-expiratory alveolar collapse. [6] A higher level of applied PEEP (>5 cmH 2 O) is sometimes used to improve hypoxemia or reduce ventilator-associated lung injury in patients with acute lung injury, acute respiratory distress syndrome ...
Lung compliance, or pulmonary compliance, is a measure of the lung's ability to stretch and expand (distensibility of elastic tissue). In clinical practice it is separated into two different measurements, static compliance and dynamic compliance. Static lung compliance is the change in volume for any given applied pressure. [1]
