During a cardiac arrest resuscitation, finally palpating a pulsatile flow beneath your gloved fingertips brings a sense of satisfaction like no other.

As you begin to sense your own heart palpitating, you think about medications to utilize in hopes of staving off another round of chest compressions.

You also recall that norepinephrine seems to be a popular choice in patients with shock, so maybe you should start that instead?
