Organs to be identified:
Organs to be identified:
'''Caudal lung margin''' - can evaluate for pulmonary edema,
'''Caudal lung margin''' - can evaluate for pulmonary edema, nodules, pneumonia, PTE
'''Diaphragm''' - evaluate for hernia
'''Liver''' - evaluate for general liver size, echogenicity, obvious masses
'''Gall bladder''' - evaluate for mucoceole, wall edema consistent with anaphylaxis
'''Peritoneal cavity''' - evaluate for free fluid
'''Caudal vena cava''' - evaluate size as it crosses the diaphragm. Collapsed - hypovolemia. Distended - R sided CHF vs volume overload. Expand and contract by 50% diameter is normal
'''Hepatic veins''' - distended consistent with volume overload or R sided CHF
'''Thoracic cavity''' - evaluate for pleural effusion
'''Pericardial sac''' - evaluate for pericardial effusion
'''Heart apex +/- chambers''' - general idea of size and filling
