The acute-on-chronic exacerbations of end-stage respiratory diseases often result in prolonged hospital stays, relating these events to ethical conflicts in the fields of medical futility and distributive justice. This study aimed to understand patients’ preferences for life-sustaining treatments when clinically stable and during regular follow-up visits, and to determine the factors that can influence these preferences. This was a prospective, observational, exploratory study using convenience sampling. Over a three-year period, the study enrolled 106 adult outpatients with end-stage pulmonary disease on long-term oxygen treatment with/without noninvasive mechanical ventilation with dyspnoea scores of 6 or more in the modified Borg dyspnoea scale and one of the following: Gold (chronic obstructive pulmonary disease classification) stage IV, diffusing capacity (DLCO) <40%, heart failure (New York Heart Association functional classification (NYHA)) stage III/IV, or systolic pulmonary artery pressure ≥40？mm Hg. Factors that were influential in preferences were age, gender, household status, NYHA class, and previous exposure to mechanical ventilation. There was no consensus on life-sustaining treatment preferences. Demographic factors, such as age group, gender, household status, severity of disease, and previous treatment with mechanical ventilation, seemed to affect patients’ preferences
