Important: Critical Med is an educational study and reference tool. It does not provide diagnosis, treatment directives, or emergency services, and it is not a substitute for professional clinical judgment or facility protocols. ACLS study content supports personal exam preparation only; it is not AHA-accredited and does not grant a certification card.

Version History THE BIGGEST UPDATE YET. BUILT ON THE REDESIGN — MORE TO USE ON SHIFT

The new Critical Med is live. This update adds the tools and polish we wanted next: a live vent monitor to practice on, a real night mode, and a tighter UI.

WHAT'S NEW
• Ventilator Studio — practice waveforms on a live monitor. Watch how stiff, obstructive, and combined lungs change the same breath. Home → Airway & Vent, or Ventilator Management → Practice
• Dark Mode — night-shift readable canvases, cards, and type
• Cleaner teaching pages and cards, with less chrome between you and the number
• Bug fixes — tap targets, sheets, and a pile of UI nits

EVERYTHING YOU RELY ON, STILL 100% OFFLINE
No account, no sign-in — every feature works without a signal, plus a fresh clinical brief each morning.
