Chronic Obstructive Pulmonary Disease (Copd) (Definition)

Chronic obstructive pulmonary disease, otherwise known as 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 for most days three months out of the year, two years in a row. Emphysema is a disease that damages the air sacs or the smallest breathing tubes in the lungs. COPD is commonly associated with smoking. ...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

For what reason should patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

For what reason should patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

Low oxygen...: People with COPD can develop low oxygen levels due to their lung disease. Oxygen therapy is then administered in the lowest amount needed to treat their hypoxia. Too much oxygen can actually cause lung toxicity which worsens lung function. ...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

Copd ---- what's considered a high concentration of required oxygen?

Delivery: Perspective is that 21% is the concentration from the air we breath. 2-3% increase in concentration is from each liter of oxygen added. So 1 liter is about 24% and this can go through a nasal canula tube. Over 4-5 liters, you cannot get this from a canula and need continuous flow to maintain the concentration. This would be considered "high" in my book. Not sure if this answers your question. ...Read more

Muliple organ failure do u need supplemental oxygen?

Yes: Multi-organ failure generally indicates a critical illness that affects multiple organ systems & delivery of oxygen can be compromised as lungs are generally also involved. Most patients are in the icu, on ventilatory support & continuous infusions with medications to maintain their circulation & heart function. Oxygen is the basic fuel for all cellular metabolic processes. ...Read more

Can there be a way to tell if i need supplemental oxygen at home?

Can there be a way to tell if i need supplemental oxygen at home?

Talk to your doc: Need for supplemental oxygen at home is used in advanced stages of various chronic lung disorders such as copd, cystic fibrosis, pulmonary fibrosis etc. It would be useful to get a detailed assessment done by a pulmonologist to decide if chronic o2 therapy would be beneficial. Level of support depends on underlying severity & type of disease. Talk to your pulmonologist for further assessment. ...Read more

What are the oxygen level guidelines, before someone needs supplemental oxygen?

What are the oxygen level guidelines, before someone needs supplemental oxygen?

Depends...: Actual medical history and details of the reason for monitoring the oxygen level are required before this question can be answered. The level isn't the same for someone with no medical issues vs someone with cyanotic heart disease (for example). If there is a specific person you are asking about - discuss your concern with their physician. ...Read more
