你的氧气设备
你, your health care provider 和 your oxygen supplier should all work together to choose the oxygen system that is right for you — one that takes into account your lifestyle 和 activities, 以及你需要的氧气量. 我们的目标是拥有你能够并且愿意佩戴的氧气设备, 所以你可以继续享受你平常的活动.
Some of the factors to consider when choosing your system 和 equipment are listed below:
- The amount of oxygen your doctor has prescribed for you (written as liter flow of 每分钟氧气量,如2升/分钟)
- 你多久离开一次家
- 你外出的时候都做些什么
- 你的体型,力量和耐力与装备的重量
- The size 和 layout of your home (for instance, whether your house has two or more stories)
- 不管你是用鼻子呼吸还是用嘴呼吸
- 你的灵活性
- 个人偏好
目前可用的三种氧气系统是:
- 压缩气体系统
- 便携式氧气浓缩器(POCs)
- 液氧系统
压缩气体系统由固定式浓缩器组成, 在家里使用, 还有一个小氧气罐, 在室外使用. The liquid oxygen system consists of a stationary concentrator or reservoir to use while you are in your home 和 an 非固定的 tank to use when you go out. The 可移植的 oxygen concentrator can serve as both the 非固定的 device 和 the stationary concentrator in certain circumstances.
系统类型 | 动态组件 | 固定组件 |
压缩气体系统 | Small, 预充好的油箱每周会送到您的手中, 这取决于你用了多少氧气, 或者在家里装满一整晚的油箱(又名a home-fill系统).
These small tanks must be used in conjunction with an oxygen conserving device or regulator (OCD) that delivers the oxygen in pulses, 这样氧气供应就能持续更长时间. |
氧气浓缩器有50英尺长的管道 |
液氧系统 | 小的,可再填充的水箱,你从水库填满所需 | 50英尺高的氧气罐 油管 |
便携式氧气浓缩器(POC) | A small electric device that can be worn on the back or wheeled around, 使用普通电力或电池, 即使在车里也很容易充电, 而且不需要油箱或加注. 正确输送氧气的最大管道长度为7英尺. 这些装置可以被带上飞机. | |
流动和便携式氧气设备
而条款 可移植的 和 非固定的 oxygen equipment are often used interchangeably, there is an important difference. In 1999, the 5th Oxygen Consensus Conference differentiated between 可移植的 和 非固定的 oxygen systems.
Portables are defined as easily moved devices that are not designed to be carried 和 weigh more than 10 pounds. 移动设备的定义是重量小于10磅, 可供日常使用, 设计成由病人携带的, 以每分钟2升的速度持续4到6个小时. They are normally small aluminum cylinders or liquid oxygen containers equipped with oxygen conserving devices (OCDs).
E型坦克是更大、更老的金属坦克,它是轮式的. 对于某些人和某些情况,它们可能是正确的选择, 但一般不认为是移动装置. They are often used as back-up systems in the home, should the electric power in the home fail.
氧气保存装置(OCD)
The oxygen conserving device (OCD) is the device on your small compressed gas tank that makes the oxygen supply last longer. 它使氧气只有在你呼吸时才被输送出去. Not all OCDs deliver the same amount of oxygen as a continuous flow would, so it is important that your oxygen saturation be tested at rest 和 with activity while you are using the OCD, 确保你有足够的氧气.
配件
你的氧气设备有几个配件. In addition, there are other accessories to make wearing or carrying your oxygen more comfortable. 下面是一些基本配件的例子.
- 鼻插管. Oxygen is generally delivered through 油管 和 a nasal cannula, sometimes called nasal prongs. The nasal cannula end of the 油管 fits into your nose, 和 is the most common delivery accessory.
家用固定设备配有50英尺的管道, 所以你可以在房子里自由活动. 流动设备配有较短的管道. - 氧气面罩. 氧气面罩也可用于更高的氧气需求. Oxymask是一个舒适的版本.
- 水库油管. An Oxymizer mustache or pendant can increase the amount of oxygen delivered or make the oxygen last longer.
- 加湿器的瓶子. 较高的氧气浓度会使鼻粘膜干燥. A humidifier attached to your stationary oxygen equipment can help prevent this dryness.
- 提箱、手推车. 流动氧气罐可以用小推车运来, 装在背包里,有时甚至作为腰包. 便携式氧气浓缩器装在自己的箱子里, 背在背上或挂在肩上.
更高的氧流量
Rates of 4 liters/minute or greater are considered higher oxygen flow.
- Liquid systems deliver higher flows of oxygen for longer periods of time. Unfortunately, it is getting more difficult to obtain liquid oxygen systems.
- 保氧装置可能无法输送足够的氧气. 当流量大于4升/分钟时,连续流效果更好.
- There are high-flow stationary concentrators that go up to 10 liters/minute.
- For oxygen settings higher than 6 liters/minute, a high flow nasal cannula is needed.
- Certain oxygen face masks 和 reservoir cannulas can boost the delivery of oxygen 和 make high oxygen flows more comfortable.
- 对于高流量氧气引起的鼻腔刺激,可以尝试RoEzIt.
- 由于背压的增加和流动阻力的增加, disposable humidifier bottles are not recommended for flows greater than 6 liters/min.
你r provider can help you choose an oxygen company, or you may choose any company you want. 一些保险政策规定了你必须使用哪个氧气公司.
Most insurance policies cover supplemental oxygen when the medical necessity for oxygen is demonstrated. This necessity is based on the oxygen saturation or the arterial blood gas measurements.
一般, 如果你的血氧饱和度低于89%, 或者你的paO2低于60毫米汞柱——无论是在休息时, with activity or during sleep — then you qualify for supplemental oxygen. 有关更多信息,请参见 补充氧气的需要.
你r oxygen supply company will give you instructions for cleaning your equipment. 下面列出了一些基本知识:
- 鼻插管应该每周更换一次.
- The long 油管 attached to your stationary equipment should be changed monthly. Neither the nasal cannula nor the long 油管 from your stationary equipment should be washed.
- If an oxygen face mask is used, it should be cleaned twice weekly with warm 肥皂水.
- Oxygen concentrators usually require a weekly filter cleaning with warm 肥皂水.
- 如果您正在使用加湿器, 每天至少清空一次, 用肥皂和温水清洗瓶子, 确保所有的肥皂都被冲洗干净, 然后把瓶子装满蒸馏水. 不要使用自来水,因为其中的矿物质会损坏你的设备.
