Should every patient go to the cath lab after cardiac arrest? "Rush everyone" is the wrong answer — and this episode explains why.

We walk through the post-ROSC coronary decision: considering ACS in every post-arrest patient, how the 12-lead ECG drives it, immediate angiography for ST-elevation, and what the COACT and TOMAHAWK trials showed for patients without ST-elevation — plus the high-risk features that still warrant urgent cath.

ANZCOR-aligned reasoning for paramedics, nurses and doctors.

In pre-arrest arrhythmia management, one clinical question sits above all others — and your answer to it determines whether you have time to think or need to act right now.

In this episode we break down the haemodynamic stability assessment: what "unstable" actually means in an ALS algorithm (it's narrower than most clinicians assume), the four adverse features that define it, and why getting this distinction right stops you from either under-treating a deteriorating patient or over-treating a stable one who just needs time and a 12-lead.

We also cover the "symptomatic vs unstable" trap — one of the most common sources of clinical confusion in pre-arrest arrhythmia management — and walk through how the ABCD assessment anchors every decision that follows.

One Cent Miracles: How Aspirin Matched the Power of Clot Busters

In emergency medicine, some of the most powerful interventions don’t come from expensive drugs or high-tech equipment — they come from a simple pill that costs cents.

In this episode we dive into the landmark ISIS-2 trial that changed cardiology forever. Aspirin alone reduced mortality by 23% — nearly matching the powerful clot-buster streptokinase. When used together, they delivered a remarkable 42% reduction in deaths.

We break down:

• How aspirin stops platelets from clumping and worsening a heart attack
• Why it remains a Grade A recommendation in ANZCOR and ARC guidelines
• The correct 300mg dose and why it should be chewed
• When not to give aspirin

A powerful reminder that great medicine isn’t always complicated — it’s about doing the simple things right, at the right time.

Essential listening for paramedics, emergency nurses, and doctors.

Why You Should Stop Using Pulse Checks to Gauge CPR Quality

In the middle of a cardiac arrest, it’s tempting to reach for a pulse to see if your compressions are working. But what if that reassuring pulse you feel isn’t what you think it is?

In this episode, we explore why manual pulse checks during CPR are often unreliable. Evidence shows they can be misleading in up to 50% of cases, frequently detecting retrograde venous pulsations rather than true arterial flow. This false confidence can lead teams to unintentionally ease off on compression quality when it matters most.

We break down:

• Why ANZCOR no longer recommends pulse checks as a measure of CPR quality
• The superiority of waveform capnography (ETCO2) for monitoring resuscitation effectiveness
• How a sudden rise in ETCO2 is one of the best early signs of ROSC
• Practical team strategies to maintain high-quality CPR without unnecessary interruptions

If you’ve ever paused or adjusted compressions based on a pulse check, this episode will change how you approach resuscitation forever.

Listen now for clear, ANZCOR-aligned insights you can apply on your very next shift.

Adrenaline (epinephrine) is a key drug in ANZCOR-aligned ALS for cardiac arrest — but what's really happening? Its alpha-adrenergic effects cause vasoconstriction, boosting coronary and cerebral perfusion to improve ROSC chances. The beta-adrenergic side ramps up heart rate and contractility... which can spike myocardial oxygen demand and contribute to poorer neurological outcomes in survivors.

We cover the basics: standard 1 mg dosing, timing in shockable rhythms, and why evidence shows ROSC gains but often no long-term neuro benefit — or even risks. Quick, practical insights for paramedics, nurses, and doctors.

Is induced hypothermia dead? In this episode, we dive into the shifting paradigm of Advanced Life Support (ALS) post-resuscitation care. Following the TTM-2 trial and updated ILCOR/ANZCOR guidelines, the focus has shifted from deep therapeutic hypothermia (32–34°C) to strict fever prevention and targeted normothermia (36°C) for comatose post-cardiac arrest patients. We discuss the evidence, the dangers of over-cooling, and how to implement effective post-arrest care to improve neurological outcomes. 

Topics Covered:

• Why the "cool everything" approach failed.
• Targeted Temperature Management (TTM) vs. Therapeutic Hypothermia.
• Fever prevention as the new standard (≤37.5°C).
• Management of shivering and rewarming strategies.
