Why did my doctor prescribe oxygen for me?
每个人都需要氧气. 事实上,身体的每个组织和细胞都需要持续的氧气供应才能正常工作.
Oxygen gets into our cells and tissues via the lungs. The lungs breathe in oxygen from the air, 然后将氧气通过数百万个叫做肺泡的小气囊输送到血液中. 红细胞中的血红蛋白会吸收氧气,并将其运送到身体的组织和细胞中.
间质性肺病 会在肺组织中氧气进入血液的肺泡处引起炎症和/或疤痕(又名纤维化)吗. 这种炎症和/或疤痕使氧气难以进入血液. 因此, the amount of oxygen in the blood drops, 身体的组织和细胞可能无法获得足够的氧气来保持正常运作. Not enough oxygen in the bloodstream is called 低氧血症。.
How did my doctor determine that I need supplemental oxygen?
The amount of oxygen in the bloodstream can be easily measured two ways:
- 血氧定量法 This is the method used most often. 一个小, 夹式装置将光照射到你的手指或耳垂上,并测量红细胞中携带氧气的血红蛋白吸收的光量. By calculating the amount of light absorption, 该设备可以测量血红蛋白与氧分子的饱和程度, or O2 sat. Normally, the oxygen saturation of the blood is around 98 to 100 percent.
- 动脉血气研究 在这个过程中,血液从动脉中抽出,通常在手腕,使用针和注射器. 然后,血液通过分析仪来测量溶解在血液中的氧气量. 这个结果被称为 动脉氧压(paO2), and is normally 80 to 100 mm Hg.
The body needs enough oxygen to keep the blood adequately saturated, so that cells and tissues get enough oxygen to function properly. 此外, 细胞和组织既不能“储存”氧气,也不能“赶上”氧气——它们需要持续的氧气供应. When the oxygen saturation falls below 89 percent, or the arterial oxygen pressure falls below 60 mmHg — whether during rest, 活动, sleep or at altitude — then supplemental oxygen is needed.
您的医疗保健提供者可以通过在您休息和步行时对您进行测试来确定您的补充氧气需求, 还可以安排一个夜间血氧仪来测试你晚上的血氧饱和度. 高空模拟测试也可用于测试您在8000英尺(大多数客机的客舱压力)的氧饱和度。.
When and how often do I have to wear my oxygen?
你的医疗保健提供者会给你开一个处方,告诉你什么时候应该戴氧气,戴多少, based on the results of your testing. The prescription should specify the following:
- The appropriate oxygen flow rate or setting, 以每分钟的升氧流量(lpm或l/min)表示,这将使您的饱和度保持在90%或以上
- 什么时候应该戴上氧气(例如,在活动中,过夜或连续)
- The type of equipment that will accommodate your lifestyle needs
Why would I need to wear oxygen while sleeping?
Everyone's oxygen levels in the blood are lower during sleep, due to a mildly reduced level of breathing. Also, some alveoli drop out of use during sleep.
如果你清醒时的血氧饱和度大于94%, 你的睡眠饱和度不太可能降到88%以下. 然而, 如果你在睡觉时对你的血氧饱和度有疑问,你的十大赌博平台排行榜可以给你做一个夜间血氧饱和度测试.
How do I know that I'm using the right amount of supplemental oxygen?
To determine if you're getting the right amount of supplemental oxygen, your oxygen saturation must be measured while you are using your oxygen. 当你休息时,你的十大赌博平台排行榜或氧气供应商的呼吸治疗师应该用氧气测试你的血氧饱和度, 走路的时候, 如果表示, 当你睡着的时候. 只要你的饱和度在90度,你就能得到适量的补充氧气.
Should I buy my own finger oximeter to test my oxygen saturations?
It is probably a good idea to buy a finger oximeter, 这样你就能确保你得到了适量的补充氧气. Finger oximeters are available on the internet, through medical supply companies and even in sporting goods stores.
How will using supplemental oxygen benefit me?
When a person isn't getting enough oxygen, all organs of the body can be affected, 尤其是大脑, 心脏和肾脏. Wearing supplemental oxygen keeps these organs, and many others, healthy. 有证据表明, 对于低氧血症的人来说, supplemental oxygen improves quality of life, exercise tolerance and even survival.
Supplemental oxygen can also help relieve your symptoms. 你可能会从呼吸急促、疲劳、头晕和抑郁中得到缓解. You may be more alert, sleep better and be in a better mood. 你可以做更多的活动,比如旅行,包括到高海拔地区旅行.
呼吸短促等症状可能是由缺氧以外的原因引起的. In these cases, supplemental oxygen may not relieve the symptom. 但如果测试显示你没有得到足够的氧气,佩戴氧气仍然很重要.
Does my need for supplemental oxygen mean that I don't have long to live?
People live for years using supplemental oxygen.
Will I always need to use supplemental oxygen?
That depends on the reason oxygen was prescribed. If your lung or heart condition improves, 在没有补充氧气的情况下,你的血氧水平会恢复到正常范围, 那你就不再需要它了.
Can I become "dependent on" or "addicted to" oxygen?
没有所谓的“依赖”或“上瘾”补充氧气——每个人都需要持续的氧气供应来生存. 如果血液中没有足够的氧气供应你的组织和细胞, then you need supplemental oxygen to keep your organs and tissues healthy.
Does supplemental oxygen cause side effects?
It is important to wear your oxygen as your provider ordered it. If you start to experience headaches, 在开始使用补充氧气后感到困惑或困倦, 你可能吃得太多了.
每分钟4升或以上的氧气设置会导致鼻粘膜干燥和出血. 在氧气设备上安装加湿器或使用某些软膏可以帮助预防或治疗干燥. For more information, see "Higher Oxygen Flows" in 你的氧气设备.
Will I be able to go out and about with my oxygen equipment?
目标是让你尽可能多地继续你的日常活动. 你应该与你的医疗保健提供者和氧气供应公司合作,获得允许你做这些事情的氧气设备. 选择适合你和你的生活方式的设备是非常重要的——正确的动态氧气设备可以在提高生活质量方面发挥重要作用.
