The shock worked. The rhythm converted. And then V-fib came right back. Now what?

Part two of this series explores the physiology and pharmacology driving recurrent V-fib so you can respond confidently when shocks aren’t enough.

You'll learn how the body's sympathetic nervous system response keeps the heart unstable, why epinephrine can both help and hurt, when to reach for lidocaine over amiodarone, and what the research says about the emerging role of esmolol to target the storm itself (not just the arrhythmia).

Topics discussed in this episode:

• The sympathetic nervous system and cardiac arrest
• Why epinephrine both helps and hurts
• Amiodarone vs. lidocaine: which is better?
• Key findings from the ROC-ALPS trial
• Why antiarrhythmics don't replace defibrillation
• The evidence behind esmolol in refractory V-fib
• 3 lessons for codes when ACLS isn't enough

Sometimes V-fib doesn't respond to the shock at all. Sometimes it converts and comes right back. Those are two completely different problems.

In this episode, Sarah breaks down the science behind why defibrillation fails, how to recognize the difference between refractory and recurrent V-fib, and respond when shocks aren't working. You'll learn how to start approaching the electrical storm at the bedside — that means understanding transthoracic impedance, optimizing your pad placement, and knowing when to reach for double sequential defibrillation.

Topics discussed in this episode:

• Refractory vs. recurrent V-fib
• The physiology of ventricular fibrillation and re-entry tachycardias
• Misconceptions about defibrillation
• Transthoracic impedance and how to reduce it
• Anterior-lateral vs. anterior-posterior pad placement
• Double sequential defibrillation: evidence and objections
• Key findings from the DOSE VF trial

Imagine being able to cut your hospital's code blue events outside of critical care in HALF in just six months. That's exactly what happened when Sarah built her hospital's rapid response team from the ground up.

Nurse Gwenny takes over the show to find out how she did it, from the pitch that got the program started to the skills that actually matter on rapid response teams. She also shares what disqualifies a candidate even when the resume is perfect, why so few resources exist for rapid response training, and how she’s filling that gap herself.

Whether you're hoping to start a rapid response program at your hospital or just want to feel more confident the next time you call one, this episode is for you.

Topics discussed in this episode:

• How Sarah became a rapid response nurse
• The backstory behind the Rapid Response RN Podcast
• The impact of having a rapid response team
• How you can start a rapid response program
• Rapid response education and (lack of) resources
• Hiring red flags that override a strong resume
• Soft skills nursing school never teaches
• Trusting nursing intuition when vitals look fine

Topics discussed in this episode:

• Self-care and resilience as a discipline
• The nursing choice: fracture or adapt
• Building a life that isn't fully defined by the institution
• Important things we don’t say to each other
• What patients actually need from their nurses
• Therapy, medication, and sleep as nursing tools
• An exercise to audit your cup-fillers vs. cup-drainers

Getting ROSC is not always the win we sometimes think it is. It's what we're looking for the entire resuscitation, but the real challenge begins once we get it… and what we do in the next few hours has a major impact on patient outcomes.

In this episode, Sarah shares a real rapid response case to walk through the physiology, decision-making, and advocacy of post-arrest care. The 2025 AHA post resuscitation guidelines have brought important shifts to post-ROSC management, from how aggressively to oxygenate to when it's safe to prognosticate. Don't miss the full breakdown!

Topics discussed in this episode:

• Oxygenation and ventilation: how to avoid hyperoxia and hypoxia
• Perfusion, pressors, and the limits of MAP
• Temperature management guidelines
• Sedation, analgesia, and the paralyzed-but-awake patient
• Diagnostics: timing, priorities, and what to rule out
• How to use neuroprognostication the right way
• How to talk to families without giving false hope
• Nursing priorities and how to advocate for your patients

The AHA just updated the playbook on acute pulmonary embolism. The old classification system is gone. Heparin drips are no longer the default. And if your instinct is to push for intubation, that could be the thing that makes your patient worse.

In this episode, Dr. Mark Creager, lead author of the 2026 AHA Multi-Society Guideline on Acute Pulmonary Embolism, breaks down exactly what's changed, how the new guidelines help teams make better decisions faster, and what nurses need to know about frontline PE management.

Learn what the data says about oxygen therapy, anticoagulation, vasopressors, and the decisions that matter most when your PE patient starts to slide.

Topics discussed in this episode:

• The new A to E classification system and how to categorize patients
• Clinical signs that your PE patient is deteriorating
• Oxygen therapy: why intubation can be dangerous
• Vasopressor therapy and when to add vasopressin
• Low-molecular-weight heparin vs. unfractionated heparin
• PE response teams: when to activate and who should be on the team
• What you can do when your hospital has no PERT
• When to transfer by classification (and when it may be too late)
• The nurse's role in early recognition and escalation

"There has to be a better way." We've all thought it. This episode is proof that nurses can be the ones to make it happen.

In this episode, Sarah is joined by Kat Siaron, rapid response nurse and co-author of the RRT STAR study that shows what happens when nurses are empowered to act before a clear stroke diagnosis is made. They walk through a patient case that exposed a dangerous gap in inpatient stroke response, traps like sedation hangover that mask stroke presentations, and how the nurse-led Code Stroke process has drastically improved time to crucial intervention.

You'll hear about the step-by-step workflow, where rapid response nurses and physicians fit in, and how you can advocate for change in your hospital.

Topics discussed in this episode:

• The patient case that led to Kat’s RRT STAR study
• Why inpatient stroke times lag behind ER stroke times
• The consequences of ordering stat CT instead of Code Stroke
• Symptoms and prognosis of basilar stroke
• The step-by-step Code Stroke process
• The rapid response team's role in stroke activation
• Results and impact of the study
• How they overcame pushback to drive institutional change
• Stroke mimics and what to do next
• How to advocate for a nurse-led stroke alert at your hospital
