Your two hands will function differently while scanning. One is your “probe hand” (Figure 5.4). The probe hand always holds the probe and you may change which hand is your probe hand depending on where and from which side of your patient you are imaging. However, this hand's function is to work the probe. Your other hand is your “helper hand” which is used to palpate external landmarks and physically stabilize the patient or the probe on the patient, which is explained subsequently. Briefly, in standing patients, your helper hand is your “V trough” during TFAST and Vet BLUE, cupping the sternum to keep your patient from swaying (every time you lose contact, you prolong the study, which is not always in the patient's best interest) (see Figure 5.4). While performing AFAST, your helper hand is used to move less haired skin over your probe placement site for such views as the spleno‐renal (SR) and hepato‐renal (HR) in flank areas, and the cysto‐colic (CC). For TFAST recumbent views, the helper hand can lift the sternum off the table top for less weight on the probe head, which allows for finer movements and less pain because of less pressure on your patient's intercostal space. Finally, during Vet BLUE, the acoustic window you acquire may be moved together with skin, dependent on the mobility of your patient's skin, caudal and cranial over intercostal spaces at each Vet BLUE region.
