每个人都需要氧气. In fact, every tissue and every cell in the body needs a constant supply of oxygen to work properly.
氧气通过肺部进入我们的细胞和组织. 肺从空气中吸入氧气, then pass the oxygen into the bloodstream through millions of tiny air sacs called alveoli. Hemoglobin in the red blood cells then picks up the oxygen and carries it off to the body's tissues and cells.
间质性肺病 can cause inflammation and/or scarring (aka fibrosis) in the part of the lung tissue where oxygen passes into the bloodstream — the alveoli. This inflammation and/or scarring make it difficult for oxygen to move into the bloodstream. 因此, 血液中的含氧量下降, and the body's tissues and cells may not receive enough oxygen to keep functioning properly. 血液中没有足够的氧气 低氧血症.
血液中的含氧量有两种测量方法:
- 血氧定量法. 这是最常用的方法. 一个小, clip-on device shines a light through your finger or earlobe and measures the amount of light absorbed by the oxygen-carrying hemoglobin in the red blood cells. 通过计算光的吸收量, the device can measure how saturated the hemoglobin is with oxygen molecules, or O2 sat. 正常情况下,血液的氧饱和度在98%到100%之间.
- 动脉血气研究. In this procedure, blood is drawn out of an artery, usually in the wrist, using a needle and syringe. The blood is then sent through an analyzer to measure the amount of oxygen gas dissolved in the blood. 这个结果被称为 动脉氧压(paO2),正常为80 ~ 100mmhg.
身体需要足够的氧气来保持血液充分饱和, 这样细胞和组织才能获得足够的氧气来正常运作. 此外, cells and tissues can neither "save up" nor "catch up" on oxygen — they need a constant supply. 当氧饱和度低于89%时, 或者动脉氧压低于60毫米汞柱——无论是在休息时, 活动, 睡眠或在高海拔时,需要补充氧气.
Your health care provider can determine your supplemental oxygen needs by testing you while you are at rest and while walking, and can also order an overnight oximetry study to test your oxygen saturation at night. A high altitude simulation test is also available to test your oxygen saturation at 8000 ft (the cabin pressure of most airliners).
Your health care provider will write a prescription for when and how much you should wear your oxygen, 根据你的测试结果. 处方应注明以下内容:
- 适当的氧气流速或设置, expressed as liter flow of oxygen per minute (lpm or l/min) that will keep your saturations at or above 90 percent
- When you should wear your oxygen (for instance, during 活动, overnight or continuously)
- 设备的类型将适应您的生活方式的需要
每个人在睡眠时血液中的含氧量都较低, 因为呼吸轻微减弱. 此外,一些肺泡在睡眠中会停止使用.
If your waking oxygen saturation is greater than about 94 percent on room air, it is unlikely that your saturation during sleep will fall below 88 percent. 然而, your doctor can order an overnight oximetry test if there is a question about your oxygen saturation levels while you are sleeping.
来确定你是否得到了适量的补充氧气, 当你使用氧气时,必须测量你的血氧饱和度. Your provider or a respiratory therapist from the oxygen supplier should test your oxygen saturation on oxygen while you are at rest, 走路的时候, 如果表示, 当你睡着的时候. As long as your saturation is in the 90s, you are getting the right amount of supplemental oxygen.
买一个手指血氧计可能是个好主意, so that you are sure you are getting the right amount of supplemental oxygen. 手指血氧仪可以在网上买到, 通过医疗用品公司,甚至体育用品商店.
当一个人没有得到足够的氧气时, 身体的所有器官都会受到影响, 尤其是大脑, 心脏和肾脏. 补充氧气可以保持这些器官和许多其他器官的健康. 有证据表明, 对于低氧血症的人来说, 补充氧气可以提高生活质量, 运动耐受性甚至生存.
补充氧气也有助于缓解你的症状. You may feel relief from shortness of breath, fatigue, dizziness and 抑郁症. 你可能会更警觉,睡得更好,心情也更好. You may be able to do more activities such as traveling, including traveling to high altitudes.
Symptoms such as shortness of breath may be caused by something other than lack of oxygen. 在这些情况下,补充氧气可能无法缓解症状. But if tests show you are not getting enough oxygen, it is still important to wear your oxygen.
人靠补充氧气可以活好几年.
这取决于十大赌博平台排行榜给病人开氧气的原因. 如果你的肺或心脏状况改善了, and your blood oxygen levels return to normal ranges without supplemental oxygen, 那你就不再需要它了.
There is no such thing as becoming "dependent on" or "addicted to" supplemental oxygen — everybody needs a constant supply of oxygen to live. If there is not enough oxygen in your bloodstream to supply your tissues and cells, 然后你需要补充氧气来保持你的器官和组织健康.
按照十大赌博平台排行榜的指示佩戴氧气是很重要的. 如果你开始感到头痛, confusion or increased sleepiness after you start using supplemental oxygen, 你可能吃得太多了.
Oxygen settings of 4 liters per minute or above can cause dryness and bleeding of the lining of the nose. A humidifier attached to your oxygen equipment or certain ointments can help prevent or treat the dryness. 有关更多信息,请参阅“更高的氧气流量” 你的氧气设备.
The goal is to have you continue as many of your usual activities as you can. You should work with your health care provider and oxygen supply company to get oxygen equipment that will allow you to do these things. Choosing the right type of equipment for you and your lifestyle is very important — the right ambulatory oxygen equipment can play a major role in improving quality of life.
