Morphine’s obvious benefit is its ability to control pain and therefore decrease sympatheticRead more

How Safe is Mechanical CPR?

Question – How safe is mechanical CPR compared to manual CPR? There are two devices used for mechanical CPR – the AutoPulse and LUCAS – neither of which has been demonstrated to show a survival benefit over manual CPR in recent studies (CIRC, LINC, PARAMEDIC). Could these devices be causing more injuries compared to manualRead more

What Patients Require Emergent Cath Lab Activation?

Question – STEMI criteria are insensitive for all cases of acute coronary artery occlusion. Among patients with chest pain, what are the other criteria for cath lab activation? Let’s talk more ACS. Patients that need emergent reperfusion therapy are those that have an acute coronary occlusion. ECG findings of ST-elevation will not catch all cases ofRead more
