Patients with pulmonary tuberculosis can have different degrees of hemoptysis, especially hemoptysis when the patient requires bed rest, maintaining the affected side of the bed, while the head is tilted to the side. This position is adopted in order to make the coughing up of blood better, to avoid asphyxiation due to haemoptysis and failure to cough up blood in time, and to avoid the blood from entering the healthy side of the lung and blocking the bronchi and forming obstructive pneumonia, which aggravates the symptoms of wheezing. When tuberculosis hemoptysis, tuberculosis bacilli are coughed out with the blood, so the patient can avoid the blood with bacteria from entering the healthy side of the lung and causing the spread of tuberculosis, thus aggravating the degree of tuberculosis infection. The patient’s lung mobility on the affected side is also reduced by lying down, which is conducive to the formation of blood crusts on the bleeding vessels and to stop bleeding. Therefore, lying on the affected side is to reduce the occurrence of asphyxia, to avoid the formation of obstructive pneumonia and the spread of tuberculosis in the healthy side of the lung, and to facilitate hemostasis.
