An example of the manner in which AFAST with an AFS works in nontrauma monitoring is for the patient with pancreatitis that on day 1 has an AFS of 1 without any AFAST target organ abnormalities. The following day, the Global FAST approach is used, and the AFS has increased to 3. Moreover, Global FAST further evaluates for effusions using TFAST, volume status, and any lung complications using Vet BLUE, and no additional effusions other than the ascites are found. This is significant patient information because likely the disease process is worsening. The finding of an increase from AFS 1 to 3 dictates a more aggressively diagnostic and therapeutic pursuit. Without this approach as an extension of the physical exam, these changes are often missed until the complications advance even more and the patient becomes overtly clinical. In contrast, the following day the AFS has decreased to 0, likely reflecting a positive response to therapy, important information for the clinician as well as the client.

Additional practical Global FAST examples would include cases with right‐sided congestive heart (CHF) and making decisions on whether the patient requires therapeutic abdominocentesis as well as tracking ascites using the AFS for response to CHF therapy; and the use of the AFS postoperatively in vomiting septic abdomen cases to screen for abdominal‐related complications, including effusions and ileus or dehiscence, or thoracic‐related complications such as aspiration pneumonia or myocardial dysfunction, and so forth. The Global FAST approach screens these systems as part of its standardized protocol.
