If the patient's condition is particularly serious, the oxygen concentration can be appropriately increased. However, in the process of oxygen inhalation, it is necessary to closely observe the patient's condition changes. If the patient's condition improves, the oxygen concentration should be gradually reduced to avoid oxygen poisoning caused by too high oxygen concentration. Especially for asthma complicated with chronic obstructive pulmonary disease, low concentration oxygen should be the main way of oxygen inhalation, and the oxygen concentration should be controlled within 30% as far as possible.
Matters needing attention in using oxygen generator in winter:
Placement problem: the oxygen generator should be placed in a dry and ventilated place, not in a humid place, such as bathroom, toilet, closed storage room, etc. When in use, put the oxygen generator in a flat place and turn it on after it is placed stably.
Cleaning problem: Do a good job of cleaning regularly, cut off the power supply, clean the casing regularly with a rag or sponge dipped in cleaning liquid, be careful not to let the cleaning liquid enter the machine from the gap, clean the humidifying bottle regularly, and disinfect the oxygen inhalation tube every day to ensure oxygen hygiene.
Power consumption: the oxygen generator uses an independent power socket. If you live in remote rural areas or old cities, install voltage regulators in areas with aging lines! Philips oxygen generator is equipped with intelligent pressure monitoring and alarm, which will give an alarm in case of failure.
