Breath-holding is very serious in the advanced stage of lung cancer in the elderly, which requires psychological support, body position and breathing control guidance from healthcare personnel and family members. 1. Psychological support: most of the late stage lung cancer will be accompanied by dyspnea symptoms, patients often feel fearful and even choose to give up their lives. At this time, family members and healthcare personnel need to give support to patients and help them regain confidence in treatment, and they can divert their attention to alleviate their symptoms of nervousness and anxiety. 2. Positional guidance: for patients who are lying down with respiratory distress, the chest and abdomen can be raised appropriately, and for patients who are standing up, the upper body can be tilted forward with the hips against the wall to alleviate the respiratory distress. 3. Breathing control training: let the patient carry out deep breathing training, the deeper the better, but with the premise that the patient feels comfortable. If the breath-holding of elderly people with advanced lung cancer is very serious and cannot be relieved after a long time, they should communicate with doctors in time and deal with it under doctors’ guidance, and their family members should give maximum support to the patients and must not be discouraged so as not to cause delay in their condition.
