![]() ![]() A lot of it depends on gut, or experience, in fitting the story together.” “But if the O2 saturation is a little off, maybe even 94 when we really want 97 or above, and the child is coughing a lot, we might want to do a chest X-ray to be sure. Often times you can have a normal exam, especially with a little child who doesn’t know how to take deep breaths,” Dr. “You don’t always need to get a chest X-ray if you hear the crackling, if there are other symptoms like a persistent cough, fever and a change in respiratory rate, which might be a little bit quicker.”ĭoctors also measure oxygen saturation (through a pulse oximeter, a small sensor clipped to a finger). “Rales, or crackling, is the classic sound when it comes to pneumonia, and when you are hearing it in a specific area of the lungs, then it is likely to be bacterial pneumonia,” Dr. The doctor does this to check for what is called “rales,” which are small clicking, bubbling or rattling sounds in the lungs. This includes listening to your lungs with a stethoscope. One type, pneumocystis jirovecii pneumonia (PCP), generally affects people with weak immune systems, including those with AIDS.Ī physician will first ask about your medical history and take a physical exam. Fungi from soil or bird droppings can cause pneumonia in people who inhale large amounts of these organisms. It most often occurs in older children and young adults. Also known as walking pneumonia, this type is considered atypical because its symptoms and physical signs may vary. Viral pneumonia is usually not as serious as bacterial and typically goes away more quickly. People may be more likely to get bacterial pneumonia if they first have viral pneumonia. Responsible for about one-third of all pneumonia cases, this type is caused by various viruses, including flu (influenza). ![]() ![]() The pneumonia might just affect one small area of your lung, or it may encompass all of both of your lungs. This is caused by bacteria, the most common of which is streptococcus pneumoniae. There are literally dozens of different causes of pneumonia, grouped by the most common types. Pneumonia is caused by bacteria, viruses or fungus. ![]() “There has been a big push regarding antibiotics stewardship-how to treat patients appropriately with antibiotics, who needs antibiotics, and also what are some of the non-antibiotic alternatives to treat patients,” says Charles Dela Cruz, MD, a pulmonologist at Yale Medicine. Researchers at Yale School of Medicine are studying how to better identify different types of pneumonia strains, so that the antibiotics given to patients are the best possible fit. At Yale Medicine, our physicians are experienced and skilled at treating everything from the most basic form of pneumonia to the more serious cases that might require hospitalization. There are more than 30 different microorganisms (or microbes) that can cause pneumonia, and identifying the correct one isn’t always easy. It can be mild or life-threatening, especially to the elderly, the very young or those with compromised immune systems. The infection, which is caused by bacteria, viruses or fungi, can occur in one or both of the lungs. Whether it’s bacterial, viral-or the friendlier sounding “walking” pneumonia-chances are you or someone you know has had this illness at some point. ![]()
