MONA Acronym (ON-AM)
O: Administer oxygen: by means of nasal cannula or face mask, oxygen administration provides more concentration for myocardial uptake in order to promote tissue profusion to meet metabolic demands. It can also decrease the discomfort associated with tissue ischemia and prevent additonal damage.
N: Administer Nitroglycerin, IV: Nitro has a vasodilation effect, which promotes perfusion and lowers the myocardial workload and oxygen demand.
A: Administer Aspirin: this works by inhibiting platelet activity and interrupts aggregation at the rupture site, thrombolysis
M: Administer morphine: this relaxes the endothelial lining and promotes profusion of the heart tissue by reducing the myocardial workload. It also controls pain and reduces the risk of developing life-threatening dysrhythmias and other complications.
