We know that POCUS can be used to diagnose many different types of infection. We also know that these infections can lead to serious systemic illness in the form of sepsis. Whenever we see a patient with sepsis, we want to know the source infection as quickly as possible so that we can treat it appropriately with antibiotics and/or a procedural intervention. Therefore, this paper takes a look to see if using ultrasound in the diagnostic work up of these undifferentiated infected patients can help diagnose the source and lead to better treatment.
