RESUS

ResponseV-A ECMO
Heart failure needing cardiac support (Eg; Arrest)
VV ECMO - Respiratory failure, provides no cardiac support

ResponseVeno-Arterial ECMO
Heart failure and needs cardiac support. VV ECMO most suitable for respiratory failure and provides no cardiac support.

ResponseConventional treatment resistant Respiratory failure – example Life threatening asthma
Conventional treatment resistant cardiac failure – severe myocarditis, intractable dysrhythmias
Life threatening poisoning – calcium channel blockers, beta-blockers
Environmental – life threatening hypothermia

ResponseFailure of conventional life/organ support (cardiac and respiratory)
Reversible medical condition
Temporising measure to facilitiate corrective surgery / transplant

ResponseFutile (Bridge to nowhere)
Inappropriate use of resources
Poor baseline level of function
Terminal illness

ResponseIABP decreases mortality in cardiogenic shock. If medical refractory to medical resuscitation, IABP placement is indicated.
Most evidence now not beneficial in most shock. Good in acute mitral valve incompetency
