Lactate Clearance in Sepsis: What It Tells You, and What It Doesn’t
Lactate is one of the most-ordered labs in critical care and a cornerstone of sepsis resuscitation. But it is also widely misunderstood. This guide explains what an elevated lactate means, how lactate…
What Is PEEP, and How Is It Set on the Ventilator?
Positive End-Expiratory Pressure (PEEP) is one of the most important and most misunderstood knobs on the ventilator. It is the pressure that remains in the airways at the end of exhalation, preventing…
Understanding ARDS: A Plain-Language Primer for Clinicians

Sepsis is a medical emergency in which the body’s response to infection injures its own tissues and organs. Because outcomes worsen with every hour of delay, the Surviving Sepsis Campaign distilled the…
What Is APRV? A Plain-Language Guide to Airway Pressure Release Ventilation
Airway Pressure Release Ventilation (APRV) is one of the most powerful and most debated modes in critical care. Used well, it can recruit collapsed lung and preserve a patient’s own breathing; used…
How to Read an Arterial Blood Gas (ABG): A Step-by-Step Guide for Clinicians
The arterial blood gas (ABG) is one of the most information-dense tests in critical care, yet it intimidates many clinicians at the bedside. This guide breaks ABG interpretation into a repeatable, five-step…
