Yet another study adds to growing evidence that guideline-recommended hand placement for chest compressions may not correspond to the optimal anatomic target. In this prospective ultrasound study of 152 adults, investigators used transthoracic echocardiography to identify the left ventricular outflow tract (LVOT) and the ideal area of maximal compression (iAMC), then mapped these structures onto standardized external chest-wall coordinates relative to the sternum. The LVOT wa

In patients with cardiac tamponade, earlier point-of-care ultrasound (POCUS) in the emergency department is associated with a shorter time to pericardiocentesis. Prompt bedside diagnosis can expedite definitive treatment in this life-threatening condition. References: 📖 Eke OF, et al.

In patients with acute pulmonary embolism, echocardiographic right ventricular enlargement is associated with an increased risk of in-hospital shock, cardiopulmonary resuscitation, and mortality. Recognizing RV enlargement at the bedside can therefore provide valuable prognostic information and help identify patients who may require closer monitoring, more aggressive therapy, or escalation of care.

Cardiac tamponade is one of the few potentially reversible causes of cardiac arrest. When a pericardial effusion is identified during cardiac arrest and the clinical presentation raises suspicion for tamponade physiology, emergent pericardial drainage should be performed. In one study, patients undergoing pericardiocentesis for suspected tamponade during cardiac arrest had a substantially higher survival to hospital discharge than all other patients (15% vs. 1%), highlighting

The development of cardiac tamponade depends more on the rate of pericardial fluid accumulation and pericardial compliance than on the absolute size of the effusion. With an acute pericardial effusion, the pericardium has not had time to stretch, so even 50 mL of rapidly accumulating fluid may produce tamponade physiology. In contrast, a chronic pericardial effusion allows the pericardium to gradually increase its compliance, permitting up to 2 liters of fluid to accumulate b
