Beta-blockers may blunt the response to epinephrine; what does this imply?

Explanation:
Beta-blockers block the beta-adrenergic receptors, so epinephrine’s beta-mediated effects (such as increased heart rate and some bronchodilation) are dampened. But epinephrine still acts on alpha receptors to cause vasoconstriction, which helps raise blood pressure. Because the response can be reduced, you don’t stop using epinephrine or assume it won’t help. Instead, follow the protocol and use adjunct measures to support the patient’s status, which may involve additional dosing or other recommended interventions to achieve the desired effect.
