Forced lateral position: Patients with pleurisy lie more to the affected side, mainly to relieve chest pain, and patients with large pleural effusions lie more to the affected side mainly to relieve respiratory distress. Pleurisy is an inflammation of the pleura caused by pathogenic factors (usually viral or bacterial) stimulating the pleura, also known as “pleurisy”. It may be accompanied by fluid accumulation in the pleural cavity (exudative pleurisy) or no fluid accumulation (dry pleurisy). After the inflammation is controlled, the pleura may return to normal, or two layers of pleura may adhere to each other. The main clinical manifestations are chest pain, cough, chest tightness, shortness of breath, and even dyspnea. So, what are the prevention methods of forced lateral recumbency? The following are the prevention methods of forced lateral recumbency. 1, stand suck squat call: stand on the ground, two arms side up, while deep inhalation, then two arms crossed to the chest, the body squatting, while deep exhalation. Twice a day, 20-30 strokes each time.
