Pneumonia physical exam findings4/18/2023 Focal or unilateral wheezes typically indicate focal pneumonia, however diffuse or bilateral wheezes could mean upper airway bronchospastic disease or diffuse multifocal pneumonia. Lower respiratory tract infections can cause secretion and edema where the lung is infected. The typical high-frequency whistling noise is very specific to airway narrowing. Wheezes - lung sounds recorded a stethoscope Then listen for wheezes, crackles, and egophony. Pull out your dusty Bates’ Guide to Physical Examination and History-Taking and lookup egophony. Grab that decorative rubber neckpiece and listen to at least eight lung fields bilaterally. It sounds simple, but it’s easy to overlook a borderline febrile patient when everything about the patient screams “worried well.” Any vital sign abnormality should raise your suspicion for infection, and you should proceed with a very thorough and comprehensive physical exam.įocus your physical exam on a complete auscultation of the lungs. Just like sepsis screening, COVID-19 screening requires vital sign vigilance because the vital sign abnormality might be subtle. Look for a temperature greater than 37.8 C, oxygen saturation less than 95%, and a peripheral pulse rate greater than 100 beats per minute. Start with the fundamentals: perform vital sign screening on patients who complain of a fever, shortness of breath, cough, or flu-like symptoms. Thorough vital sign measurement and careful auscultation are essential to identify patients with a risk of significant lower respiratory illness. Now would be a good time to review what the signs of pneumonia are. The first step of any COVID-19 diagnosis depends not on the test itself, but on the fundamentals of physical examination described by Rene Laennec more than 200 years ago and still taught to this day on the first week of our clinical educations. Public health institutions are recommending that providers risk stratify patients with geographic and personal risk of exposure to COVID-19 presenting with signs and symptoms of lower respiratory illness. How is a healthcare provider at the frontlines of care to know when to sequester and test for COVID-19? The answer might be hanging around your neck. If your clinical practice is like mine at the Emergency Department, then you have to negotiate between the high volumes of sick and worried patients and the overutilization of costly and constrained resources. Diagnostic imaging might be available in every emergency department, but clinicians cannot expose every patient with a cough to 4 millisieverts of radiation. Providers can expect a turnaround time of 2 or more days for test results due to the constrained supply of RT-PCR assays. However, access to these technologies remains limited. Radiologists can spot characteristic imaging patterns of lower respiratory infection caused by COVID-19 within minutes of CT scanning. Diagnostics companies have developed several RT-PCR assays that can identify COVID-19 within hours. Within two months, researchers identified and sequenced a novel respiratory illness. The global scientific and public health response to the continuing COVID-19 pandemic has been remarkable.
