There is a perpetuated myth in the healthcare community that high levels of oxygen can "stop a patient from breathing". This concept is widely viewed as a reason to withhold oxygen from people suspected of suffering from COPD, with the result being under-treated patients. There is research that suggests that administration of too much oxygen in the blood can cause negative changes in the cardiovascular system. Please note the main difference between DELIVERING high concentrations and the patient absorbing too much oxygen. People with breathing problems may receive high concentrations but not be able to absorb it. This is not a reason to withhold oxygen. Current protocols suggest that heathcare practitioners deliver as much oxygen as is necessary to achieve and maintain normal blood concentrations but not to allow too much to enter the bloodstream (they can check it easily without having to take blood).
In COPD a person breaths in air but it gets stuck in their lungs and can't exhale all the air from their lungs. This results in the barrel-chested look of COPD patients. Because the person can't fully exhale, there is a build-up of CO2 in the lungs. The drive for a person to breath is low CO2 levels which stimulates the body to intake more oxygen/air. If you give a person with COPD oxygen, more CO2 will build up in their body further decreasing their respiratory rate. It is not contra indicated but should be used with caution. In healthy people, high levels of carbon dioxide is what triggers respiration (to help get rid of the carbon dioxide), but because people with COPD are used to having high levels of carbon dioxide their bodies become immune to it and respiration in this case is triggered by low levels of oxygen. Therefore if you give a person with COPD high concentrations of oxygen, you are removing their trigger to breath, leading to respiratory depression or even arrest (stop breathing completely). This is known as hypoxic drive (hypoxia means low levels of oxygen)

how long can you live on oxygen whenuyou have emphysema and your 82 years old
Barrel chest is common in patients with COPD. The chest expansion is the compensation of the body for the needed oxygen.
85% of patients diagnosed with cor pulmonale have COPD
NO
An ashen skin color is a result of inadequate oxygen circulation or perfusion. As in patients with chronic obstructive pulmonary disease (COPD)
This varies with the severity of the COPD and how well the patient is doing on whatever the current oxygen therapy happens to be. The doctor will adjust the oxygen if the patient seems to need more than what was originally prescribed; patients on long-term oxygen therapy have regular check-ups to make sure all continues to go well. Doctors will sometimes use a device called a pulse oximeter for rapid assessment, especially if the patient is experiencing some distress that he or she was not having before. And some doctors are now encouraging patients to have a pulse oximeter at home, so they can monitor their oxygen saturation after physical activity, or between doctor's visits.
COPD and lung diseases.
The following are some of the ways doctors are treating COPD to help improve health: use of medications to help ease symptoms, such as bronchodilators, vaccinations to help prevent different types of infections that can complicate COPD, oxygen therapy and in some cases surgical procedures.
Aricept is contraindicated if you are hypersensitive to it's main ingredient (donezepril). It is cautioned (slightly less serious than contraindicated) if you have cardiac conduction defects, you have a sinus syndrome, asthma, copd. It is also cautioned if you have a seizure disorder, you use NSAIDS or have PUD. But you need to contact your doctor or your pharmacist if you have any further questions about your medications and if they are safe for you.
We do see patients with COPD having various grades of clubbing. Most of them (>95%) do not show any evidence of lung cancer or associated ILD on X-ray or HRCT. All of these patients had low SpO2 and low DLCO. Probably chronic hypoxia leads to clubbing in COPD patients. Interestingly I never saw a severe asthma patient with chronic hypoxia developing clubbing.
In patients with chronic hypercapnia such as COPD, respirations are primarily stimulated by hypoxia.
Pneumonectomies are usually performed on patients with lung cancer, as well as patients with such noncancerous diseases as chronic obstructive pulmonary disease (COPD)
