Final answer:
Vasopressors in ACLS are used when a patient exhibits hemodynamic instability despite fluid resuscitation, especially in septic shock. They ensure blood pressure and organ perfusion are maintained. ACLS guidelines should always be followed for the correct administration of vasopressors.
Step-by-step explanation:
Using vasopressors in Advanced Life Support Cardiac (ALCS) is a decision based on specific clinical circumstances. They are introduced when a patient shows signs of hemodynamic instability despite adequate fluid resuscitation, particularly in the presence of sepsis. Vasopressors such as norepinephrine, epinephrine, and dopamine are used to maintain arterial pressure and ensure adequate organ perfusion. Septic shock is a common scenario where vasopressors are necessary once intravenous fluids are insufficient to maintain blood pressure and organ perfusion.
It is critical to follow ACLS guidelines which emphasize the importance of addressing reversible causes, providing high-quality CPR, and when indicated, delivering timely defibrillation. In cases of cardiac arrest, vasopressors like epinephrine are administered during the ACLS algorithm to increase the likelihood of a return of spontaneous circulation (ROSC).
