Human studies show the likelihood of false negative and false positive results are markedly decreased when asking binary questions!

透過明確定義快速超聲波的目標，可以避免與低事前測試概率相關的“釣魚探險”，這些探險往往會顯著增加假陽性結果的可能性。

By clearly defining the objectives of the rapid ultrasound, one can avoid “fishing expeditions” that are often associated with low pre-test probabilities and can lead to significant increases in the likelihood of false positive results.

學習和擴展POCUS角色的一個關鍵方法是習慣於提出臨床驅動的問題（通常是是/否的二元性質）。當存在中等到高的事前測試概率時，POCUS被證明是最有幫助的，這強調了臨床評估和患者評估的重要性，以推動臨床問題的解答。

A key approach to learning and expanding the role of POCUS is to get comfortable asking clinically driven questions (often yes/no binary in nature). POCUS is proven to be most helpful when there is a moderate to high pre-test probability that the pathology in question exists, which stresses the value of clinical assessment and patient evaluation to drive the clinical question to answer.

POCUS廣泛地包括對腹部和胸部整體的損傷評估，包括自由腹部液體、氣胸、胸腔積液、一般肺病理、基本心臟病理、體積和液體反應性、腎盂擴張、膽囊壁水腫、子宮蓄膿、氣腹、胃腸運動以及在病人到達後幾分鐘內的超聲引導程序。

POCUS broadly incorporates assessment of injury within the abdomen, thorax as a whole, including free abdominal fluid, pneumothorax, pleural effusion, general lung pathology, basic cardiac pathology, volume and fluid responsiveness, renal pelvic dilation, gall bladder wall edema, pyometra, pneumoperitoneum, gastro-intestinal motility, and ultrasound guided procedures within minutes of patient arrival.

在獸醫專業中，如何進行FAST檢查以及FAST檢查應包含哪些內容存在相當大的差異。
最近的獸醫調查顯示，在尋找腹部和胸部FAST檢查的自由液體和氣胸之外，臨床醫生評估的內容幾乎沒有標準化。

There is considerable variation in the veterinary profession regarding how to perform FAST exams and what should be included within a FAST exam.
Recent veterinary surveys demonstrate there is little standardization of what clinicians evaluate during both abdominal FAST
and thoracic FAST exams, beyond a search for free fluid and pneumothorax.

POCUS 提供了單獨進行身體檢查無法獲得的相關信息，因此它是分流、身體檢查和其他臨床診斷測試或發現的補充；它並不能取代它們。
人類醫學的證據支持 POCUS 可以改善臨床決策，並且當與其他臨床發現結合時，確認了高達 50% 的疑似臨床診斷，並在 23% 的病例中支持改變初步診斷。
