The goal of this guide is to help students expand their practical knowledge of Echocardiography in order to produce cardiac ultrasound studies that are of maximum possible diagnostic quality.
Good sonography includes:
-Skilled use of the transducer.
-Effective patient positioning.
-Working with the patients’ breath in order to gain access to portions of the cardiac anatomy that are difficult to image.
-Constantly re-adjusting the ultrasound machine settings in order to assure the best resolution for the conditions encountered.
-Having a compassionate and caring concern toward the patient and the quality of the imaging provided.
This guide will first teach some important fundamental properties of ultrasound and how specific adjustments to the ultrasound machine can improve the resolution of two-dimensional, spectral Doppler and color Doppler images. It also teaches principles for setting-up the ultrasound machine and recording and transmitting images to the server.
Finally, the guide teaches the student how to organize and perform an echocardiographic study, with particular emphasis on how to use the ultrasound transducer in conjunction with advanced machine adjustments under many different conditions and challenges.
NOTICE: Always take into consideration the patient’s health and ability before having them perform any respiratory maneuvers or a body position that is uncomfortable.
