Proper use of an oxygen concentrator not only ensures the effectiveness of the therapy but also minimizes accidental risks, making it a reliable safeguard for long-term care at home. The following five essential points will help you and your family quickly master its use, allowing the oxygen concentrator to become your most dependable health partner! 正確使用製氧機，不僅能確保治療效果，還能避免意外風險，成為家中長期照護的安心守護者，以下五個必學重點，幫助您和家人輕鬆上手，讓製氧機成為最可靠的健康夥伴 !
1. Place in a Well-Ventilated Area and Keep Away from Fire Sources 1. 放置通風位置、遠離火源 When an oxygen concentrator is operating, it requires significant air circulation. Please place the machine in a well-ventilated space and maintain a cooling distance of at least 30 cm around the unit. Avoid stacking clutter that could obstruct heat dissipation. Since oxygen is a combustion supporter, never smoke, light a fire, or use flammable materials near the machine to prevent fire hazards. 製氧機在運作時需要大量空氣流通，請將機器放置於通風良好的空間，並保持機身四周至少30公分的散熱距離，避免堆放雜物阻礙散熱。氧氣具有助燃特性，切勿在機器附近吸菸、點火或使用易燃物，以免發生火災危險。
2. Regularly Check Oxygen Concentration and Alarm System 2. 定期檢查氧氣濃度與警報系統 Oxygen concentrators are equipped with alarms for malfunctions, low oxygen purity, and power issues. When an alarm sounds, you must immediately turn off the machine and contact a technician to verify the problem and arrange for inspection and repair. Never ignore any abnormal signal. 製氧機配備故障、低氧及電源等相關警報，當警報響起時應立即關機並聯絡技術人員確認並安排檢修，切勿忽視任何異常訊號。
3. Cleaning and Maintenance of the Intake Filter and Humidifier Bottle 3. 進氣過濾棉與濕化瓶的清潔保養 The air intake filter cotton (or external filter) should be cleaned every 100 hours of use. The air intake filter (internal) is recommended to be replaced after 3,000 hours of machine operation. If the operating environment has a high amount of dust, it is advisable to shorten the cleaning cycle.
The humidifier bottle needs to be cleaned every 2 to 3 days. Do not attach a damp humidifier bottle directly back onto the main unit. Ensure all parts are completely dry before use. 進氣過濾棉每使用間隔100 小時需要清潔，進氣過濾器建議在機器使用3,000 小時後更換；若使用環境粉塵較多，建議可縮短清潔週期。 濕化瓶每2 ~ 3天需要清潔，請勿將未乾的濕化瓶直接裝回主機，使用前確認所有零件均已徹底乾燥。

4. Adhere to Flow Rate Settings and Usage Duration 4. 遵循流量設定與使用時間 Accurately set the flow rate (L/min) according to your physician's recommendation, and avoid adjusting it higher or lower on your own. If the user experiences discomfort such as chest tightness or shortness of breath, they should stop using the device immediately and seek medical evaluation. 依照醫師建議的流量（L/min）精準設定，避免自行調高或調低。若使用者出現胸悶、呼吸急促等不適，應暫停使用並就醫評估。 Image by jcomp on Freepik
5. Prepare Emergency Backup Power 5. 準備緊急備援電源 To prevent treatment interruption due to power failure, homes should be equipped with an Uninterruptible Power Supply (UPS) system of no less than 500 VA or a power bank. This is especially important for patients using the device for long periods at night, as it can effectively reduce the risk associated with sudden outages. Regularly test your backup equipment to ensure it can supply power normally during critical moments. 為避免斷電導致治療中斷，家中應備有不低於500VA的UPS不斷電系統或行動電源，尤其對夜間長時間使用的患者而言，能有效降低突發狀況的風險。定期測試備援設備，確保關鍵時刻能正常供電。
Conclusion:
The oxygen concentrator is a critical instrument for maintaining quality of life. Mastering the five essential safety points above ensures a safe and worry-free usage experience. Proper placement, attention to alarms, filter maintenance, flow control, and backup power are all indispensable for creating the most reliable home oxygen therapy environment for your family. 結語： 製氧機是維持生命品質的關鍵儀器，掌握以上五大安全要點，能讓使用過程更安心。正確的放置、注意警報、濾網保養、流量控制與備援電源缺一不可，為家人打造最可靠的居家氧療環境。
