Yes, shortness of breath and labored breathing is one symptom of chronic lung conditions. The person cannot get enough O2 or get rid of enough CO2 because many of the alveoli are collapsed.
difficulty breathing
shallow breathing. Basically if it is hard to breathe, like asthma, you'd be breathing slower than the average person which would make your breathing labored.
Yes; this is correct.
Painkillers, particularly opioids, can cause labored breathing by depressing the central nervous system, which controls respiratory functions. These medications can reduce the brain's sensitivity to carbon dioxide levels, leading to slower and shallower breathing. In some cases, they may also cause muscle relaxation, further impairing the respiratory muscles. This can result in inadequate oxygen intake and difficulty breathing, especially in higher doses.
"Asthma"
wheezing, shortness of breath, and labored breathing.
Labored breathing is a sign of nervouses. Its perfectly natural.
The term used to desribe difficult or labored breathing is dyspnea. Asthma is one cause of dyspnea; pneumonia is another. When a person has trouble breathing and it seems that they are working hard just to inhale, you can describe it as "labored."Sometime people will actually sweat heavily due to the amount of effort they need to inhale--usually exhalation is a passive process and doesn't require muscle to work, just relax.
emphysema
Call your vet *now.*
labored breathing, Cancer, Asthma...
Emphysema causes a higher breathing rate. A person with emphysema can be "air hungry" even when getting external oxygen by mask or cannula.
