[|Human|] my mother is 87 and has not eaten in 2 weeks drinks 8 oz of gingerale per day she is home with me on hospice. Before she came home her potassium level was low and then she stopped the iv s and blood work and denied the feeding tube How long can her heart survive this. She also has copd her sats are 75-83 she refuses the oxygen she had a fall 3 months ago broke humerous requried surgery then her eating got worse. They did discover through a CT that she had a previous stroke ( the fall I think) and dementia plus PAD
[|AI|]  Serum potassium levels above 3.0 me/liter are not considered dangerous or of great concern; they can be treated with potassium replacement by mouth. Depending on the patients medical condition, other medical problems, and the patients symptoms, serum levels lower than 3.0 me/liter may require intravenous replacement. Decisions are patient-specific and depend upon the diagnosis, the circumstances of the illness, and the patients' ability to tolerate fluid and medication by mouth. Over the short-term, with self-limited illnesses like gastroenteritis with vomiting and diarrhea, the body is able to regulate and restore potassium levels on its own. However, if the hypokalemia is severe, or the losses of potassium are predicted to be ongoing, potassium replacement or supplementation may be required. In those patients taking diuretics, often a small amount of oral potassium may be prescribed since the loss will continue as long as the medication is prescribed. Oral supplements may be in pill or liquid form, and the dosages are measured in me (milliequivalents). Common doses are 10-20mEq per day. Alternatively, consumption of foods high in potassium may be the first option in replacing potassium. Bananas, apricots, oranges, and tomatoes are high in potassium content. Since potassium is excreted in the kidney, blood tests that monitor kidney function may be ordered to predict and prevent potassium levels from rising too high. When potassium needs to be given intravenously, it must be given slowly. Potassium is irritating to the vein and is usually administered at a maximal rate of 10 me per hour. Moreover, infusing potassium too quickly can cause heart irritation and promote potentially dangerous rhythms such as ventricular tachycardia. The body is usually able to maintain potassium levels within the normal range as long as there is adequate potassium in the diet. When the body loses potassium due to a short-term illness, the body is able to compensate for the loss. When the potassium loss is being ongoing, it is important for the patient and health-care professional to anticipate the loss, and consider routine potassium replacement. The most essential step in any treatment plan for COPD is to stop all smoking. It's the only way to keep COPD from getting worse which can eventually reduce your ability to breathe. But quitting smoking isn't easy. And this task may seem particularly daunting if you've tried to quit and have been unsuccessful. Talk to your doctor about nicotine replacement products and medications that might help, as well as how to handle relapses. Your doctor may also recommend a support group for people who want to quit smoking. It's also a good idea to avoid secondhand smoke exposure whenever possible. MedicationsDoctors use several kinds of medications to treat the symptoms and complications of COPD. You may take some medications on a regular basis and others as needed. BronchodilatorsThese medications which usually come in an inhaler relax the muscles around your airways. This can help relieve coughing and shortness of breath and make breathing easier. Depending on the severity of your disease, you may need a short-acting bronchodilator before activities, a long-acting bronchodilator that you use every day or both. Regards Chat Doctor.
