For patients with respiratory failure, treatment is one aspect, and nursing is equally important. A nursing plan should be developed in advance, starting with keeping the airway clear to avoid aspiration of liquids or food into the trachea. It is necessary to frequently help the patient turn and pat their back to facilitate the expulsion of phlegm, while also enhancing nutrition and increasing the intake of various nutrients. During the remission period of respiratory failure, persist in exercising, performing exercises like knee protections to strengthen the activity of the respiratory muscles. Adapt clothing according to seasonal and climatic changes to avoid catching a cold. In nursing, it is important to maintain vital signs, pay attention to the care of the skin and oral mucosa, promptly clear phlegm, and avoid factors that trigger breathing difficulties, such as the stimulation from cold wind and cold air. Maintain regular life patterns, engage in appropriate physical exercise, and prevent the occurrence of colds.
