Copd (Definition)

COPD may include chronic bronchitis, emphysema, or both. Chronic bronchitis is the production of increased mucus caused by inflammation. Bronchitis is considered chronic if you cough and produce excess mucus most days for three months in a year, two years in a row. Emphysema is a disease that damages the air sacs and/or the smallest breathing tubes in the lungs. ...Read more

Why would patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

Why would patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

Low blood oxygen: At the advanced stages of copd, the lungs do not perform their function well, oxygen has a harder time crossing into the blood stream. At this point, the body is not getting enough energy, the blood oxygen level is low. Raising the amount of inhaled oxygen offsets the problem, and prolongs life. Oxygen is used at the lowest amount that would achieve the goal. ...Read more

Does COPD cause low oxigen levels in patients after surgery?

Does COPD cause low oxigen levels in patients after surgery?

COPD: COPD patients have a persistent state of low oxygen. They need to be monitored with yearly Pulmonary Function Tests with DLCO. Medical management with inhalers like combivent and dulera (formoterol and mometasone). Self management with home pulse OX. Also therapy for nicotine addiction if present. The stress of surgery often flares COPD depending how long and what anesthesia was used. You must be careful with giving O2 ...Read more

Will increasing a COPD patient's oxygen when taken to 5, 000 ft altitude injure her?

Will increasing a COPD patient's oxygen when taken to 5, 000 ft altitude injure her?

Usually not: Check with the doctor to make sure the patient does not have a tendency to retain carbon dioxide. Also, it is best to have an oximeter, a device that measures oxygen levels, with you. It will allow you to use just enough, not more not less. ...Read more

Oxygen must be carefully prescribed by a doctor with monitoring of the patient's oxygen levels because giving too much oxygen is harmful as is not giving enough! See your doctor if you think your oxygen level is low! ...Read more

At what level is low blood oxygen harmful for children with copd?

At what level is low blood oxygen harmful for children with copd?

If your oxygen level drops too low, could that cause a non epileptic seizure. Also, if you have severe COPD would exercise lower your oxygen level.

If your oxygen level drops too low, could that cause a non epileptic seizure. Also, if you have severe COPD would exercise lower your oxygen level.

Yes and yes: A very low oxygen tension can make people have seizure like activity or unconsciousness depending on the response of the cells of circuitry in your brain. The cells can become irritable and have more discharges. People with COPD are exercised to see if they need o2 as oxygenation can drop with activity depending on the severity of disease. ...Read more

Copd cause low grade fever? I've heard when carbon builds up in body? Or low oxygen?

Copd cause low grade fever? I've heard when carbon builds up in body? Or low oxygen?

Sometimes: COPD may cause low grade fever if inflammation in the airway is present. The lung is responsible for eliminating carbon dioxide produced by the body. If carbon dioxide is high then the oxygen level will be lower. An arterial blood gas can determine if hypercarbia is present. Therapy includes bronchodilators and possible low flow oxygen. ...Read more

I have copd, was put on oxygen due to a bad cold and low oxygen levels. Why am I short of breath while on this oxygen? It's set at 2.

I have copd, was put on oxygen due to a bad cold and low oxygen levels. Why am I short of breath while on this oxygen? It's set at 2.

Several Factors: Your shortness of breath can be due to inadequate oxygen getting into your blood. This is a function of gas exchange.
It might be manageable by increasing your oxygen, but you should check with your doctor first. Sometimes increasing the oxygen can actually make you breathe in and out less, resulting in the retention of carbon dioxide - which is bad.

Good luck and feel free to ask more. ...Read more

Why would hemoglobin and hematocrit be low in a COPD patients?

Why would hemoglobin and hematocrit be low in a COPD patients?

Another illness: Anemia of chronic disease does not occur as a result of common emphysema / chronic bronchitis (the usual copd). If such a person is also anemia, another cause should be sought. Anything from being an vegetarian who doesn't know how to supplement to losing blood from an undiagnosed stomach cancer can be the cause. COPD is hard enough with an undiagnosed cause of anemia.
