The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.
Urinary strictures
Bethanechol chloride (Urecholine) can be harmful to patients who have a urinary tract obstruction or bladder wall weakness. The medication has the ability to contract the bladder, causing pressure to build up in the urinary tract. In these patients, an increase in urinary tract pressure could cause the bladder to rupture.
What is Urinary retention?
- The inability to completely empty the bladder is referred to as urinary retention. The onset can be abrupt or gradual.
- Symptoms of sudden onset include inability to urinate and lower abdominal pain.
- When symptoms appear gradually, they may include loss of bladder control, mild lower abdominal pain, and a weak urine stream.
- If there is an obstruction or stricture (narrowing) in or around the bladder, or if the muscles in or around the bladder are weak, urine may be retained. Urinary retention can also be caused by certain types and locations of tumors, certain medications, being dehydrated, or having constipation.

COPD, emphysema, bronchitis , and asthma. Chronic obstructive pulmonary disease (COPD), which incorporates chronic bronchitis.
<h3>What about chronic obstructive pulmonary disease?</h3>
- COPD symptoms include persistent coughing or wheezing.
- Excessive sputum or phlegm.
- Respiration difficulty.
- The signs and symptoms include wheezing, expulsion mucus (sputum), and trouble breathing.
- It's frequently brought on by prolonged exposure to irritant gases or particulates, most often from cigarette smoke.
- Heart disease, carcinoma , and a variety of other diseases are more likely to occur in people with COPD.
- In around 9 out of each 10 cases, smoking is regarded to be the first cause of COPD.
- The lining of the lungs and airways can get damaged by the toxic compounds in smoke.
- Quitting smoking can help stop the deterioration of COPD.
- Short-acting bronchodilator inhalers are the initial line of therapy for the bulk of COPD patients.
- Breathing is formed easier by bronchodilators, which relax and expand the airways.
- Short-acting bronchodilator inhalers are available in two varieties: beta-2 agonist inhalers, like salbutamol and terbutaline.
- For those with chronic obstructive pulmonary disease (COPD) who have (or are in danger for) hypercapnia, an excessive amount of oxygen can be harmful.
- Patients with hypercapnia are frequently over oxygenated, despite established standards and acknowledged danger.
