Abstract:
Transesophageal echocardiography (TEE) is a safe and minimally invasive tool that can routinely provide high-quality anatomic and hemodynamic information in the severely ill. Despite its potential for frontline acute care clinicians, TEE use has typically been reserved for diagnostic experts in the cardiac-surgical milieu. With the continued evolution of point-of-care ultrasound into increasingly sophisticated domains, TEE has gained steady uptake in many nontraditional environments for both advanced echocardiographic assessment as well as answering more goal directed, fundamental questions. This article introduces the workings of the TEE transducer, presents a systematic approach to a goal-directed hemodynamic assessment, and includes a series of illustrative figures and narrated video presentations to demonstrate the techniques described.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
