Mastery Guide Series
Anesthesia & Critical Care

35+ clinical guides — born from a single ABG Mastery Guide on May 22, 2025, and grown into the foundation of ENKI Clinical.

The Legacy That Became
ENKI Clinical

On May 22, 2025, the first guide was published — the ABG Mastery Guide, created in collaboration with Sophia (ChatGPT-4o). That single guide grew into a series of 35+ clinical references spanning anesthesia and critical care.

From October 13 to December 5, 2025, the official Telegram channel ran its daily pearl series — 100 clinical pearls over 53 days, covering 30+ topics. That effort didn't stop — it evolved into ENKI Clinical, a full clinical decision-support platform built to reduce cognitive load in ICU and anesthesia practice.

These guides remain free, always — because the mission began with teaching, and teaching never ends.

To my beloved mother — may God grant her eternal peace.
To my father — whose memory remains a source of strength.
To my brother — deeply missed.

To every patient suffering in silence,
and every clinician striving in hardship,
across all hospitals, all languages, and all limitations.

This series is for you — in need, in service, or in solitude.
