What is the cause of pulmonary insufficiency

summary

The lung is an important channel for our breathing. We have vital capacity measurement in every routine physical examination. Lung is not good, running can not stand, prone to chest tightness, breathing difficulties. One of my classmates is that every time I run in the exam, I will not make it, or even faint. We rushed to give first aid and took him to the hospital. Further examination revealed that he had pulmonary insufficiency. Let's share the symptoms of pulmonary insufficiency.

What is the cause of pulmonary insufficiency

First: blood vessels and heart beats. Enlarged pulmonary artery systolic pulsation, sometimes accompanied by systolic or diastolic tremor. The left lower edge of sternum palpates the right ventricular hyperdynamic systole.

Second, the pulmonary hypertension of heart sound appeared, which was manifested by the enhancement of pulmonary valve components of the second heart sound. The second heart sound is wide split. Right ventricular volume will increase, resulting in a sudden expansion of the enlarged pulmonary artery, resulting in a systolic ejection sound, which can be clearly felt in the second intercostal space on the left edge of the sternum. The third and fourth heart sounds of right ventricle are often found in the fourth intercostal space on the left edge of sternum, and their heart sounds will be enhanced when inhaled.

Third: heart murmurs. When there is a second heart sound between the second and fourth ribs on the left edge of sternum, the diastole begins immediately. In the early stage, there is a sigh like high-profile decreasing murmur, which will be enhanced when inhaled. Due to pulmonary artery dilatation and increased right ventricular volume, systolic ejection murmur appeared after the second intercostal ejection murmur on the left edge of sternum.
