Emphysema Oxygen General Anesthesia
Is it harder for people with emphysema to get enough oxygen while they're under general anesthesia?
Not usually: Room air contains only 21% oxygen. When a patient is under general anesthesia, we can increase the amount of oxygen breathed to 100% if necessary. So even with emphysema, it is rare to have problems receiving enough oxygen. However, patients with emphysema will have a harder time breathing on their own and recovering after surgery and general anesthesia. ...Read moreSee 2 more doctor answers
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
Under care: The patient with emphysema is sensitive to many of our anesthetic agents, that is they will depress their already damaged pulmonary function. This means that a patient with emphysema is going to spend more time in the post anesthesia care unit to make sure that they can breathe with minimal assistance. Having the patient spend the night after an operation is another way that they can be carefully. ...Read moreSee 2 more doctor answers
Is it normal right before you get knocked out by general anesthesia to feel like you cant get any oxygen and to have a heavy chest ? through the mask?
Most likely normal: Before giving general anesthesia is standard procedure to provide with the Mask 100% O2,for about 5 to 7 minutes,depending of your lungs health, to replace the air contained on your lungs, and increase the O2 reserve in case an emergency situation happens during intubation or airway manipulation. Chest tightness just before starting anesthesia is mot likely due to anxiety, narcotic or asthma ...Read more
Does generAl anesthesia cause breathlessness after becoming concious? My oxygen saturAtion was ok but i felt breathless? Why?
Muscle blockade....: With general anesthesia, neuromuscular blocking agents are often used to paralyze the muscles during the surgery. Sometimes it takes a little while for these to completely wear off. Your respiratory muscles can be affected so you are not taking real deep breaths. This can lead to the feeling of breathlessness. When the melds wear off, you feel normal again. That may be the reason for your symptoms ...Read more
O2 is good.: Long term oxygen therapy has been shown in some trials to improve mortality. It has also been shown in other trials to improve quality of life, reduce depression, improve cognitive function, improve exercise capacity, and reduce frequency of hospitalization. ...Read moreSee 2 more doctor answers
Yes and No: Patients with emphysema are at some risk for developing high carbon dioxide levels (hypercapnea) if given high doses of oxygen. The oxygen will displace the carbon dioxide off of the red blood cell resulting in higher blood levels (haldane effect). However, hypoxia (low oxygen) is more likely to kill a patient than hypercapnea (high co2) so using high dose oxygen may be needed. ...Read moreSee 1 more doctor answer
Destroys the lung: Emphysema causes destruction of lung tissue. The blood vessles in the lung get destroyed in the lung. These vessles carry the blood in the lung to pick up oxygen. If they are destroyed then, oxygen can not get into the blood vessles / blood and you get low oxygen. ...Read moreSee 1 more doctor answer
From Destruction: The destruction in the lung tissue from emphysema makes the oxygen harder to cross into the blood because there is less tissue surface left. With less air sacs to participate in gas exchange, it is harder for oxygen to cross into the blood. Does that make sense? That's why people should stop smoking. ...Read moreSee 1 more doctor answer
Emphysema is a lung disease caused by destruction of lung tissue--specifically the alveoli, which are the smallest sac-like units of the lung responsible for oxygen exchange. It is characterized by shortness of breath, an expanded chest, and possible signs of low oxygen in the body such as bluish ...Read more
