The purpose of this cohort study for patients under domiciliary oxygen therapy was to elucidate the relation between the patients' QOL and weather factors. The underlying diseases were mostly COPD. By the study end date, nine patients were lost to follow-up (Four deaths, 3 exacerbation, 2 personal reasons).This study was approved by the internal review board of our university and the patients' medical facilities.We first measured room temperature of patients' living room and bedroom every 30 minutes, using automatic thermo-recorders. Next, we visited the patients every 70-80 days and collected the data, along with the diaries, the contents of which include blood oxygen saturation, heart rate, patients' physical condition, appetite, and degree of dyspnea. The temperature data outside the patients' houses were collected from the closest measurement points of AMeDAS (Automated Meteorological Data Acquisition System).By comparing the relation between the room and outside temperatures, we found that the room temperatures were higher during cold days and somewhat lower during hot days than the outside temperatures, probably due to air-conditioning effect, but the room temperatures often exceeded 30℃.In 2005 in Osaka, the ambient temperature rose after April and the monthly average temperature was record high in June, with the peak being around the end of June. Under this circumstance, the room temperatures also rose very high, which prevented the patients from acclimatization, and a female patient was hospitalized by ambulance car. This patient experienced lowered blood oxygen saturation and tachycardia. The elevation of the room temperature is partly affected by the oxygen condensers, which generated heat.In winter 2005, on the day when it snowed and the next day, many of the bedroom temperatures were lowest, and we observed a male patient who apparently became ill due to this cold exposure and was hospitalized.

本研究对居家氧疗患者进行队列研究，旨在探讨天气因素与患者生活质量的关系。基础疾病多为慢性阻塞性肺病。到研究结束时，9例患者失去随访（4例死亡，3例病情恶化，2例个人原因）。本研究得到了我校内部审查委员会和患者医疗机构的批准。我们首先使用自动温度记录仪每30分钟测量一次患者客厅和卧室的室温。接下来，我们每隔70-80天对患者进行一次回访，并收集数据和日记，日记内容包括血氧饱和度、心率、患者身体状况、食欲、呼吸困难程度。患者屋外的温度数据从最近的AMeDAS（自动气象数据采集系统）测量点采集。通过对比室内温度与室外温度的关系，我们发现，可能由于空调的作用，室内温度在寒冷的日子比室外温度高，在炎热的日子比室外温度低，但室内温度经常超过30℃。2005年大阪的环境温度在4月以后开始上升，月平均气温在6月创下历史新高，高峰出现在6月底左右。在这种情况下，室内温度也非常高，使患者无法适应环境，一名女性患者被救护车送进医院。患者血氧饱和度降低，心动过速。室温的升高部分受到氧气冷凝器的影响，它会产生热量。2005年冬天，在下雪的那一天和第二天，许多卧室的温度都是最低的，我们观察到一位男性病人显然因为这种寒冷而生病并住院了。
