CALS Explained | Cardiac Advanced Life Support Masterclass for CTICU & Perfusion Teams

Timestamp Topic Title
[00:00] Introduction: CALS (Cardiac Advanced Life Support) Overview
[00:43] The CALS Philosophy: Think Physiology First (Preload, Afterload, Contractility, Rate)
[00:54] Physiology 1: Preload Problems (Bleeding & Tamponade)
[01:28] Preload Fix: Resternotomy Target (Less than 5 minutes)
[01:43] Physiology 2: Afterload Problems (Vasoplegia vs. High SVR)
[02:27] Physiology 3: Contractility Support (Dobutamine, Epinephrine, Milrinone)
[03:11] Physiology 4: Rate & Rhythm (Pacing Wires and Defibrillation)
[03:47] The CALS Sequence: Confirm, Pace Check, Defibrillate, Resternotomy
[04:26] Internal Cardiac Massage (Superior to External Compressions)
[04:47] Vasoactive Support During CALS (Norepinephrine, Vasopressin, Inotropes)
[05:22] CALS Pearl: Titrated vs. Large Epinephrine Doses
[05:49] Advanced Monitoring (TEE/TTE Echo, PA Catheter, SVR)
[06:20] Caution: Dynamic Indices are Unreliable Post-Bypass
[06:45] Escalation to Mechanical Circulatory Support (IABP and VA-ECMO)
[07:29] Why IABP/ECMO is Preferred over Impella During Acute CALS
[08:37] Team Roles (Surgeon, Anesthesiologist, Perfusionist, ICU Nurse)
[09:25] Common Pitfalls (Waiting Too Long, Overshooting BP, External Compressions)
[10:47] Quick Reference Summary (5-Minute Open, Pacing Wires, Shock Management)

Welcome to Pulse & Pressors — where critical care gets crystal clear.
In this episode, we break down CALS (Cardiac Advanced Life Support) — the specialized resuscitation protocol for post-cardiac-surgery patients.
Unlike standard ACLS, CALS focuses on physiologic precision, surgical readiness, and mechanical rescue.
???? You’ll Learn:
• The four hemodynamic pillars — Preload, Afterload, Contractility, and Rate/Rhythm
• How to rapidly recognize tamponade, vasoplegia, and myocardial stunning
• Why IABP and ECMO, not Impella, are the mechanical bridges of choice
• Titrated vasoactive and inotropic strategies (Norepinephrine, Dobutamine, Epinephrine, Milrinone)
• The five-minute rule for resternotomy and POD 0-10 bedside reopening
• Advanced monitoring (TEE, PAC, PiCCO) for shock differentiation
• The Quick Reference CALS Card for time-critical decisions
⚙️ Clinical Relevance:
CALS integrates surgery, anesthesia, and critical care into a unified framework for peri-arrest and post-bypass shock management.
It’s the bridge between hemodynamic failure and full mechanical rescue — turning chaos into choreography.
