About

ACLSMED Sim

Features
Read full description

ACLSMED Simulator turns an iPad into a high-fidelity clinical training rig: patient monitor + defibrillator + pacer, driven by an instructor remote on a second iPad or your iPhone, plus a ventilator, an IV pump and a six-station CPR skills trainer. Built for nursing schools, paramedic programs, residency simulation labs, and ACLS courses. Aligned with AHA 2025 guidelines. WHAT'S IN THE APP • MONITOR ROLE — Full patient monitor with up to six clinical channels: HR/ECG, ART/NIBP, PA, CVP, SpO₂, and EtCO₂. Real-time waveform engine, alarm flash, integrated defibrillator (charge → shock → reset), and transcutaneous pacer. Tap the ECG for any of 12 leads. Real keys, nine device styles. • INSTRUCTOR ROLE — Educator-facing control panel. Drive vitals, switch among 47 rhythm presets (sinus, atrial, SVT, junctional, ventricular, AV blocks, paced, arrest), run 33 megacode scenarios, trigger alarms, toggle CPR artifact, and step through 12-lead ECG presentations. Runs on iPad, or on iPhone and iPhone Duo as a one-handed remote. • IVMED ROLE — Infusion pump trainer with a 61-drug library, weight-based dosing, and soft/hard limit alerts. • RESPMED ROLE — Ventilator trainer, rebuilt in 2.6.1: every mode from AC/VC to APRV draws real lung-model waveforms, with trigger dips, auto-PEEP, holds, lung pathologies, and ABG. Change it from the Remote. • CPR SIMULATOR ROLE — A multi-station CPR skills trainer on one iPad. Up to six students place an iPhone running the free ACLSMED CPR app on a training manikin's sternum, hands on top: a two-minute timed test with a live quality bar per student, ring-gauge results for rate, depth zone, and hands-on time, a class leaderboard — and every student's grade delivered to their own phone. Phones join with a class code (QR or 6 digits). WORKS WITH ACLSMED CPR (FREE) ACLSMED CPR is our free iPhone companion for manikin practice: the phone lies under the student's hands and measures rate, depth zones, and hands-on time, with a 110/min metronome. Alone it scores solo practice; paired, it powers the CPR Simulator test and the monitor's compression artefact. Student phones never need a seat. • PAIRING — Private classrooms: only devices signed in to your account join, over local Wi-Fi with Bluetooth fallback; every message is signed. • AUDIO — Synthesized HR beep tracking SpO₂, ICU alarms, defib tones, CPR metronome, and voice prompts. • OFFLINE — Once paired, the simulation runs entirely on-device. WHO IT'S FOR Nurses, paramedics, EMTs, medical students, residents, and ACLS instructors who need a portable, repeatable, clinically credible megacode environment. SUBSCRIPTION REQUIRED ACLSMED Simulator requires a plan, purchased in the app. Two tiers, each as an auto-renewing monthly or annual subscription or a one-time lifetime license: • ACLSMED Pro Patient Monitor + Instructor Remote + CPR Simulator (one Monitor and one Remote, iPad or iPhone) • ACLSMED Suite adds IVmed pump + RESPmed ventilator (up to four devices) Payment is charged to your Apple ID. Subscriptions auto-renew unless cancelled at least 24 hours before the period ends; manage or cancel in Settings → Apple ID → Subscriptions. One account activates every device in your bundle.
