Q

The pharmacodynamics of Adrenaline 1:1000 show that it is a ____________ that stimulates alpha and beta adrenergic receptors. As a result, myocardial and cerebral blood flow is enhanced during CPR - causing it to be more effective due to increased peripheral resistance which improves perfusion pressures. It also reverses allergic manifestations of acute anaphylaxis, and relieves bronchospasms.
