Just imagine that for a second. The stethoscope, the universal symbol of a physician. Most of my medical students show up on day one already having purchased their stethoscope. But fast forward almost 200 years and as history tends to repeat itself, we once again, have another new technology that has emerged and received very similar attention.

More specifically, point-of-care ultrasound, also known as bedside ultrasound, also known as emergency ultrasound. In 1943, Austrian brothers, Karl and Friedrich Dussik were the first to use ultrasound as a medical diagnostic tool when they attempted to locate brain tumors. Over five decades later, we now have sophisticated portable ultrasound machines with over \u003C\u002Fp>\u003Cp dir=\"ltr\">\u003Cb id=\"docs-internal-guid-65af7dc2-7fff-f474-c93d-fe0e29520d75\">[00:01:30] \u003C\u002Fb>100 applications to diagnose and manage patients right at the bedside. So, what is POCUS or point-of-care ultrasound? It's basically an ultrasound exam that is performed by a physician at the bedside in real-time while assessing or managing your patient. You may perform it to help with the diagnosis, with the treatment plan or to even assess your treatment plan. Let's look at an example. If you had a shortness of breath patient show up, \u003C\u002Fp>\u003Cp dir=\"ltr\">\u003Cb id=\"docs-internal-guid-65af7dc2-7fff-f474-c93d-fe0e29520d75\">[00:02:00] \u003C\u002Fb>you may decide to use ultrasound at the bedside to look at their heart and you may diagnose a pericardial effusion. You may then decide to use your ultrasound to guide your pericardiocentesis procedure. You may then use it again to reassess if that pericardial effusion has now resolved. Now, one of the most fundamental concepts you have to understand before you begin to use point-of-care ultrasound is your focused question. So, what is a focused question? Your focused question is the \u003C\u002Fp>\u003Cp dir=\"ltr\">\u003Cb id=\"docs-internal-guid-65af7dc2-7fff-f474-c93d-fe0e29520d75\">[00:02:30] \u003C\u002Fb>question you want answered when you use your point-of-care ultrasound. Before you perform any application, you need to know what you are looking for. We're not radiologists. We do not perform general assessments of organs. You need to know what your question is before you're performing your scan. Let's look at some examples. If you're performing a renal scan, your focused question will be—is there hydronephrosis? If you're going to perform an ultrasound on the gallbladder, \u003C\u002Fp>\u003Cp dir=\"ltr\">\u003Cb id=\"docs-internal-guid-65af7dc2-7fff-f474-c93d-fe0e29520d75\">[00:03:00] \u003C\u002Fb>your focused question will be—are there gallstones? For an abdominal aorta, your question is—is there an aneurysm? In this course, we will review all of the basic and core point-of-care ultrasound content. Now, mind you, this is an ever-changing list. What's advanced today may be basic tomorrow. However, I will go through all the most commonly used applications for a wide range of specialties. Now, if you've never picked up an ultrasound probe, the first time you place it on a patient, \u003C\u002Fp>\u003Cp dir=\"ltr\">\u003Cb id=\"docs-internal-guid-65af7dc2-7fff-f474-c93d-fe0e29520d75\">[00:03:30] \u003C\u002Fb>this is probably the image you're going to see.
