What would be the feeling of hypercapnia ?

What would be the feeling of hypercapnia ?

Not a feeling: Some patients are chronically hypercarbic, and feel normal; if the change is rapid, patients feel very short of breath (eg as though they are suffocating), if it is slightly s ower in onset they may become very sleepy/confused (co2 narcosis). ...Read more

Hypercapnia (Definition)

Hypercapnia is excessive build up of co2 (carbon dioxide), which is normally primarily cleared by the lungs. Co2 can build up due to hypoventilation (decreased breathing, such as in sleep apnea) or poor exchange of gas between lung and blood, such as in emphysema. Over production of co2 can make clearing it more difficult for the lung to keep up, but this ...Read more

What is the definition or description of: hypercapnia?

What is the definition or description of: hypercapnia?

CO2 retention: Hypercapnia is excessive build up of co2 (carbon dioxide), which is normally primarily cleared by the lungs. Co2 can build up due to hypoventilation (decreased breathing, such as in sleep apnea) or poor exchange of gas between lung and blood, such as in emphysema. Over production of co2 can make clearing it more difficult for the lung to keep up, but this is rarely the case. ...Read more

How to treat hypercapnia?

Cause: Depends on the cause. If it is compensatory for metabolic alcolosis or hypo ventilation due to pleural effusion or something else. The physician at the bed side is the best guide. ...Read more

What is the ventilatory response to hypoxia and hypercapnia?

Increase ventilation: The basic answer to this question is that the body increases ventilation in response to hypercapnia or hypoxia. There are both environmental and individual causes that account for variability amongst individuals in their responses to these stimuli. ...Read more

Does hypercapnia help accelerate your blood flow?

Yes. In the brain. : Hypercapnea does increase blood flow in the brain by causing cerebral vessel vasodilation. This is part of a process in the brain termed cerebral autoregulation. It also can lead to peripheral vasodilation by direct effects on blood vessels. This may also lead to increased blood flow. However, this would not be a desirable effect for anything other than the body's normal response to changes in ph. ...Read more

What can cause hypercapnia but with normal oxygen levels so no hyperventilation etc?

What can cause hypercapnia but with normal oxygen levels so no hyperventilation etc?

Sleep apnea: Obstructive sleep apnea or chronic lung disease can cause hypercapnea. Also overdosing on pain medications and sedatives will decrease the breathing rate resulting in hypercapnea. ...Read more

Can emphysema cause hypercapnia?

Can emphysema cause hypercapnia?

Yes: hypercapnea is more common with COPD than with emphysema and many patients have a mixture of COPD and emphysema but I have seen a few cases of hypercapnia where emphysema was the primary issue. ...Read more

Why do patients with chronic bronchitis develop hypercapnia?

Why do patients with chronic bronchitis develop hypercapnia?

Emphysema: Chronic bronchitis is associated with emphysema which reduces gas exchange in the lungs leading to carbon dioxide retention and lower oxygen level. I trust you are under the care of a pulmonologist. ...Read more

What is the blood gas value to determine hypercapnia & hypoxia?

What is the blood gas value to determine hypercapnia & hypoxia?

See below: Hypercapnea or hypercarbia-too much carbon dioxide is measured by the pco2 in a blood gas (elevated). Hypoxia is a lack of oxygen in the blood and measured by the po2 (low). ...Read more
