🤓Critical Mind ICU Academy is now live on Google Play📱

After months of development, clinical review, testing and refinement, I am very happy to finally make Critical Mind ICU Academy available to the critical care community.

The idea behind Critical Mind is simple: ICU education should go beyond reading guidelines and memorizing protocols. We need to learn how to think through physiology, interpret changing clinical information, make decisions and understand their consequences.

Critical Mind ICU Academy was developed from the perspective of real-life critical care practice and is designed as a structured learning environment for physicians, residents, fellows and other healthcare professionals working with critically ill patients.

The Academy combines a structured critical care curriculum with more than 100 clinical MCQs, 25 interactive ICU simulations, bedside physiology and haemodynamic training, mechanical ventilation, shock, sepsis, cardiology, neurocritical care, renal failure, antimicrobial therapy, nutrition and other core ICU domains.

It also includes a dedicated haemodynamic laboratory, an ultrasound portfolio covering cardiac, lung, vascular, FAST/eFAST and transcranial Doppler applications, progress tracking, and an offline educational AI tutor and simulation debriefing environment.

One feature that was particularly important to me was accessibility. The Academy can be used in English, Spanish, Hungarian, French, German, Portuguese, Japanese and Chinese, and its core educational environment works offline without external APIs.

This is not intended to replace textbooks, guidelines, formal fellowship training or clinical judgement. The goal is different: to create a place where trainees can repeatedly learn, reason, make decisions, make mistakes safely, and try again.

As an intensivist, I built Critical Mind around something I have increasingly come to believe in during clinical practice and teaching:

Critical care is not learned by memorizing what to do. It is learned by understanding why.

Critical Mind ICU Academy is now available on Google Play.

Launch price: USD 49.99

I would be particularly interested in feedback from ICU residents, fellows, intensivists and critical care educators as the Academy continues to evolve.

Mechanical Ventilation With Increased Intracranial Pressure: Protect the Lung Without Harming the Brain

Mechanical ventilation directly influences cerebral blood flow, intracranial pressure and cerebral perfusion pressure.

CO₂ is a cerebral vasodilator, hypercapnia increases cerebral blood volume and may increase ICP. Hypocapnia produces vasoconstriction and can rapidly decrease ICP, but excessive or prolonged hyperventilation may reduce CBF enough to produce cerebral ischemia.

For this reason, normocapnia is usually the safest starting point. Short controlled hyperventilation should be reserved mainly as a temporary rescue strategy during an acute intracranial pressure crisis while definitive treatment is established.

PEEP creates another brain lung interaction.

Increasing PEEP raises intrathoracic pressure. If this increases right atrial and cerebral venous pressure, cerebral venous drainage may deteriorate and ICP may rise. If PEEP also decreases cardiac output and MAP, cerebral perfusion pressure may fall.

But when PEEP recruits lung and improves compliance, relatively little pressure may be transmitted to the pleural space. Better oxygenation may actually benefit the injured brain. PEEP should therefore be titrated according to lung recruitability, systemic haemodynamics, ICP and CPP rather than limited by an arbitrary number.

Tidal volume, Ppl and driving pressure remain important because acute brain injury does not protect the patient from ventilator induced lung injury.

Recent evidence suggests that extremely low tidal volumes combined with aggressive PEEP may not benefit patients with severe brain injury. The objective is enough protection to avoid secondary lung injury while maintaining cerebral oxygenation and perfusion.

Mechanical power adds another dimension because respiratory rate, tidal volume, pressure and flow determine how much mechanical energy reaches the respiratory system over time.

Strong spontaneous breathing also requires caution. Excessive respiratory drive may generate large transpulmonary pressure swings while simultaneously causing fluctuations in cerebral venous pressure and ICP.

Newer strategies are becoming particularly interesting.

Fully automated ventilation can continuously adjust ventilatory support while targeting predefined PaCO₂, oxygenation and lung protective ranges. The recent BRAVE study showed that automated ventilation can maintain brain and lung protective targets more consistently, although evidence remains early and does not yet establish automated ventilation as standard care.

Modes such as NAVA or proportional assistance may help preserve diaphragm activity and improve synchrony during recovery, but evidence specifically supporting them for intracranial hypertension remains insufficient.

Vereckei aVR Algorithm

When an ECG shows a wide complex tachycardia (WCT), the challenge is to determine whether it's ventricular tachycardia (VT) or supraventricular tachycardia (SVT) with aberrancy. The Vereckei aVR algorithm is a 4-step method that uses only lead aVR to guide the diagnosis. It is especially useful when a full 12-lead ECG isn't available or in emergency settings.

Step-by-step approach:
Step 1:
Is there an initial R wave in lead aVR?
◽If yes → Diagnose VT
◾If no → Proceed to Step 2
Step 2:
Is the initial r or q wave duration greater than 40 milliseconds in aVR?
◽If yes → Diagnose VT
◾If no → Proceed to Step 3
Step 3:
Is there a notch on the descending limb of a negative onset, predominantly negative QRS in lead aVR?
◽If yes → Diagnose VT
◾If no → Proceed to Step 4
Step 4:
Calculate the Vi/Vt ratio:
◽Vi = Voltage in the first 40 ms of the QRS complex
◾Vt = Voltage in the last 40 ms of the QRS complex
Interpretation:
◽If Vi/Vt ≤ 1 → Diagnose VT
◾If Vi/Vt > 1 → Diagnose SVT

Definition recap:
Vi/Vt is a voltage ratio that compares the initial and terminal parts of the QRS complex. A lower ratio suggests that the QRS complex builds up slowly (as in VT), while a higher ratio suggests faster initial activation (more typical of SVT).

How to Read a Paper

[Ritika Tuli @RitikaTuliMD]

🫀 #CardioNuggets:

What is Pulsatility Index (PI) in LVADs—and why should you care?

💡 Think of PI as how much the native LV is still pulsing in a heart that’s supported by a rotor.

🧠 What PI Represents:
PI = variation in LVAD flow during the cardiac cycle
➡️ Higher PI = stronger native LV contribution
➡️ Lower PI = weaker or more unloaded LV

Formula (simplified):
PI = (Max flow – Min flow) / Avg flow

📈 Effect of Preload on PI:
↓ Preload (e.g., hypovolemia, tamponade, RV failure)
→ Less LV filling → ↓ PI

📉 Effect of Afterload on PI:
↑ Afterload (e.g., HTN, high SVR)
→ LV struggles to eject → pressure builds
→ LVAD sees bigger flow swings
→ ↑ PI

🫀 #CardioNuggets:

Let's talk LVADs (Left Ventricular Assist Devices):

Why does the HeartMate 3 (HM3) LVAD have extremely low pump thrombosis rates?

🔹 Centrifugal Flow
Unlike axial-flow pumps (like HMII), the HM3 uses centrifugal flow, which generates lower shear stress.

🔹 Full Magnetic Levitation
➡️ No mechanical bearings = no contact, no friction, and no areas of heat or stasis where clots tend to form.

🔹 Wide Blood-Flow Pathways
HM3 is designed with larger flow gaps, giving blood more space to circulate freely.

🔹 Artificial Pulse (Washout Mode)
Every ~2 seconds, the HM3 briefly changes rotor speed to create a pulse-like effect.
➡️ This helps flush out any stagnant blood, reducing the chance of microthrombi accumulating in dead zones.

📊 MOMENTUM 3 Trial Highlights:
1,028 patients: HM3 vs HMII
At 2 years:
Pump thrombosis: 0% (HM3) vs 10.1% (HMII)
Improved survival free of disabling stroke or reoperation

#CardioNuggets :
🫀What is PAPI?

PA Pulsatility Index = (PASP - PADP) / RAP
A quick invasive marker of RV function!
It reflects the RV’s ability to generate pulsatile flow vs its filling pressure.

So PAPI assesses the RV’s ability to generate pulsatile flow relative to its filling pressure.

📉 Low PAPI suggests RV failure:
<1.85 → RVF after LVAD
<1.0 → RVF in acute MI

What is VTI (Velocity Time Integral) in echocardiography?
VTI measures the distance a column of blood travels during systole through the LVOT. It’s a vital parameter to estimate stroke volume and cardiac output noninvasively.

How is VTI measured?
1️⃣ Obtain an apical 5-chamber view (5C).
2️⃣ Place PW Doppler just below the aortic valve (at LVOT).
3️⃣ Measure the area under the velocity curve during systole➡️ that’s the VTI (in cm).
Calculation of Stroke Volume (SV):
SV = VTI × LVOT area
LVOT area = π × (LVOT diameter/2)²
Requires accurate LVOT diameter from parasternal long-axis view.
Then,
Cardiac Output (CO) = SV × HR
♦️Normal LVOT VTI: ~18–22 cm (adults)
▶️A low VTI often means reduced stroke volume, requiring further hemodynamic assessment.
