Because CPR needs no account, you can tell twenty learners to install it in the parking lot and it just works. Nothing they do touches your seat count, and nothing leaves their phone.
What goes on the table, and the ten minutes that decide whether the session runs clean.
Place it where a real monitor lives — head of the bed, screen out. This is what the team treats.
Never in a learner's line of sight. Everything you touch appears on their monitor as if the patient did it.
The suite doesn't talk to manikin hardware — it doesn't need to.
Devices find each other peer-to-peer. No internet needed once you're signed in.
Charge above 80%, set Auto-Lock → Never, turn on Do Not Disturb. A monitor that sleeps mid-arrest is the most common avoidable failure in a live session.
CONNECTION panel shows a green tick per role.One patient state, broadcast live to every instrument in the code. You change the patient; the team works the machine.

The choice persists across restarts — label a tablet "Monitor" and it stays the monitor. Change it later in Settings.
Live ECG, SpO₂, EtCO₂, blood pressure, the defibrillator and NIBP. Stand it at the head of the bed, screen to the team. This is the screen students watch and operate.
Vitals sliders, the rhythm catalog, the scenario loader and the code log. Everything you touch here surfaces on their Monitor as if the patient did it. Keep it out of their line of sight.
Yes — that is exactly what the Monitor role is for. If the team is crowding your controller to read the rhythm, you're running without a Monitor iPad. Add a second iPad, set it to MONITOR (Settings → Device Role), and stand it at the bedside. The two pair peer-to-peer — they watch the Monitor, you drive from the Remote.
Devices advertise themselves on the local network, connect automatically, and sign every message they exchange — so a stray tablet next door cannot drive your patient. Confirm on the Monitor's CONNECTION panel: green tick = live, red cross = not connected.
1. Same Wi-Fi · Bluetooth on · Airplane Mode off. 2. Accept the local-network prompt (Settings → ACLSMED → Local Network). 3. Guest/enterprise Wi-Fi often blocks device-to-device traffic — use a phone hotspot, or turn Wi-Fi off and let them pair directly. 4. Force-quit both, relaunch Monitor first.
It mirrors the students' monitor at the top, gives you every dial in the middle, and reports what the team actually did at the bottom.

| Region | Use it to… |
|---|---|
| Vitals sliders HR · SpO₂ · ABP (live MAP) · PA · RR · CVP · EtCO₂ · Temp | Deteriorate or improve in real time. Toggling a channel off removes that trace from the monitor entirely. |
| PACER | Reward correct transcutaneous pacing — or show capture failing at too low an output. |
| DEFIB 50 / 150 / 200 / 360 J | Preset the machine before a beat; reset between cases. |
| Rhythm selector | Step the catalog or jump to a specific rhythm — 60+ entries. |
| Quick Actions | Fire 12-Lead, X-RAY, Labs or Silence onto the student monitor the moment the team asks. |
| Monitor Mirror | See shocks delivered, energy used, pacer settings — without walking over. |
During an arrest watch the Monitor Mirror, not the students' hands. Shock count and energy tell you if they're following the algorithm better than their narration does.
| Settings (gear) | What it does |
|---|---|
| Device Role | Switch this iPad between Monitor · Instructor · IVmed · RESPmed · CPR — no reinstall. |
| Reset Scenario | Everything back to defaults — Sinus 60, 120/80, SpO₂ 100, EtCO₂ 40 — and clears the code log. |
| Audio | Master mute, master volume, and a switch for every cue. Mirrors the Monitor's Sounds menu. |
| Instructor Display → Disable Alarm Flashing | Stops the vital cards on your remote from flashing when they go out of range. The student Monitor keeps alarming normally. |
| Connections | The paired-device roster — a green tick per live role. |
Settings (gear) → Instructor Display → Disable Alarm Flashing. It's a comfort setting for your remote only — the patient's Monitor still flashes so the team sees the alarm. This is separate from SILENCE, which mutes the alarm sound but never the flash.

Synchronized cardioversion behaves differently from a defibrillation shock. Using it is graded reality.
The same machine becomes an AED — one iPad covers BLS and ACLS audiences.
It silences the alarm without fixing the patient. Watch who reaches for it first — best teaching moment in the app.

| Button | What it does on the Monitor |
|---|---|
| MEGA CODES | Load a scenario — sets the patient, opening rhythm and vitals. |
| RHYTHM | Open the rhythm catalog; step or jump to any of 60+ rhythms. |
| SUMMARY | The code event log — shocks, drugs, energies, timings. Wiped on power-cycle. |
| 12-LEAD · X-RAY · LABS | Reveal the scenario's 12-lead, chest film and lab panel. The 12-lead zooms, saves and prints. |
| MEDS | The drug and crash-cart reference. |
| CPR · PADS | CPR-quality overlay; place the defib pads (needed before charge/shock). |
| NIBP | Run a non-invasive BP cuff cycle — it inflates, then displays the reading, with a cuff-inflation cue and a completion chime. |
| SILENCE | Mute the audible alarm. It does not fix the patient and does not stop the visual flash. |
The Monitor is the students' machine — NIBP, PADS, ANALYZE, CHARGE and SHOCK are theirs to press. You set the patient state from the Remote; the team operates the instrument.
| Sounds menu | Cue |
|---|---|
| Mute all sound | Master kill for every cue below. |
| Master volume | Overall level for the Monitor's audio. |
| Alarm tones | The out-of-range alarm beeps. |
| HR beep | The heartbeat / QRS tone. |
| SpO₂ pulse | The pulse-oximeter tone. |
| NIBP cycle | The cuff inflation and measurement-complete sounds. |
| Voice cues | Spoken prompts — blood-pressure and analyze call-outs. |
| Patient sounds | Patient audio, such as breathing. |
Three switches, all in the Sounds menu: Mute all must be off, Master volume up, and NIBP cycle on. With those set, pressing NIBP on the Monitor inflates the cuff out loud and chimes when the reading lands.
Drag HR, SpO₂, ABP, EtCO₂ or Temp. Small increments simulate a decline; large ones an event.
Step with the arrows or pick from the catalog — 60+ entries across sinus, blocks, tachycardias, arrest rhythms and artifact.
Real patients don't jump. Drop pressure and saturation first, give the team a beat to notice, and only then convert to VF. Learners taught to read the trend beat learners taught to react to the alarm.
On the Remote, Hide from student blanks a value on the team's Monitor — so they have to earn it clinically instead of reading it off the screen.
Tap again to bring a value back; Hide ALL clears the numerics in one move.
Blank the SpO₂ and make them tell you the patient is hypoxic from the pleth, the colour and the chest — not the number. Reveal it only to confirm what they already called.

| Category | n | Examples |
|---|---|---|
| ACLS — Cardiac Arrest | 4 | Pulseless VT · Refractory VF · PEA (hypovolemia) · Asystole (opioid) |
| ACLS — Tachycardia | 4 | Stable & unstable VT · SVT · AF with RVR |
| ACLS — Bradycardia | 3 | Symptomatic sinus brady · Complete block · Mobitz II |
| BLS | 2 | Witnessed arrest with AED · Drowning |
| PALS / Neonatal | 4 | Pediatric VF · Infant brady · Peds SVT · NRP |
| Stroke | 2 | Ischemic — tPA decision · Hemorrhagic — BP management |
| ACS / STEMI | 4 | Anterior · Inferior (RV) · Anterior → VF · Posterior |
| H's and T's | 5 | Tension pneumo · Tamponade · Hyperkalemia · PE · Hypothermia |
| Medical Emergencies | 4 | Anaphylaxis · Sepsis · Submassive PE · TCA overdose |
| Advanced Resuscitation | 1 | Post-ROSC / post-cardiac-arrest care |
Each ships with a patient record, dispatch scene, history, opening vitals, expected monitor interpretation, labs, an optional chest film, and learning objectives.
ACLSMED does not step a scenario forward on its own and does not score the team's decisions. Loading a MegaCode sets the stage — patient, starting rhythm, opening vitals. You decide when the patient deteriorates, converts, or achieves ROSC.
This is deliberate. It keeps clinical judgment with the instructor instead of with a script — which is why the same scenario can teach a first-year nurse and a senior resident differently. The cost is that you must plan your beats before class.
| Beat | You do | You're testing |
|---|---|---|
| 1 · Present | Load the scenario, read the dispatch scene, let them assess. | Primary survey, rhythm recognition |
| 2 · Confirm | Fire the 12-lead or labs when asked — not before. | Whether they ask for the right data |
| 3 · Pressure | Slide pressure and saturation down. Say nothing. | Trend recognition, closed-loop comms |
| 4 · Event | Convert the rhythm — arrest, block, tachyarrhythmia. | Algorithm execution, shock/drug timing |
| 5 · Resolve | Reward correct care with ROSC, or continue the arrest. | Post-ROSC thinking — or an honest debrief |



The running log: events, shocks, energy delivered and timings. Open it the moment you call the code.
The log states it plainly: wiped on power-cycle. Debrief first, or screenshot it. Restart the app and the timeline is gone.
"You gave epi at 4:10 and the second shock at 4:55" is a conversation. "I think you were slow" is an argument.
| Instructor asks | Answer |
|---|---|
| Can students hear the NIBP cuff — and can they trigger it? | Yes. NIBP is on the Monitor (their screen); pressing it runs the cuff, inflates with sound and chimes when done. Silent? Turn on Sounds → NIBP cycle, raise Master volume, and clear Mute all. |
| How do I stop the alarm flashing on my controller? | Settings (gear) → Instructor Display → Disable Alarm Flashing. Your remote only — the student Monitor still alarms. SILENCE, separately, mutes the sound. |
| Can students view the ECG without looking at my screen? | Yes — put a second iPad in the MONITOR role at the bedside. The team watches it; your Instructor remote stays private. One iPad only means they share your screen until you add a Monitor. |
The Monitor is the patient the team treats — sounds, alarms, NIBP and the ECG all live there. The Remote is your private control surface. Give the room a dedicated Monitor iPad and most of these questions answer themselves.
Six learners, six phones, one board. Free, no account — and it measures what they actually did.
ACLSMED™ CPR is a training aid for use on a manikin only. It is not a medical device, it is not for use on or during the care of a real patient, and its readings are for education and feedback in a simulation setting.
Say it out loud before the first test — it is part of using the product correctly. The app enforces it too: every learner passes a training-only acknowledgement before they can start.
The phone works without a tablet — it just has no board to stream to. So the homework is real: "practice at home, bring me your rate and depth next week."





| Bar reads | Verdict | Say this |
|---|---|---|
| Reaches the green band | Good | "That's the depth. Hold it — don't drift." |
| Stalls in the yellow band | Almost | "Nearly there. A centimetre more, same rate." |
| Stays in the red band | Push harder | "Straight arms, shoulders over your hands, use your body weight." |
| Overshoots past green | Too deep | "Ease off slightly — over 6 cm has its own harms." |
Run the first round with the board hidden. Learners who see live feedback from the first compression never find out what their unassisted CPR looks like — and that gap is the entire lesson.

| Component | Target band | Weight | Note |
|---|---|---|---|
| Rate | 100–120 / min | 37.5% | Full marks inside the band, tapering outside it. |
| Depth | 5.0–6.0 cm | 37.5% | Penalised for shallow and excessive. |
| CCF | ≥60% floor · 80% target | 25% | Guideline floor 60%; full marks at the high-performance 80%. |
Targets follow the AHA 2025 Guidelines, Part 7: Adult Basic Life Support. Scores use a rolling average, not a single compression — so measurement scatter doesn't dock textbook technique. The three rings you see are the score; there is no hidden fourth dimension.
| Limitation | Tell learners |
|---|---|
| Recoil isn't measured | One phone sensor cannot detect leaning. Full recoil still matters enormously — you coach it by eye. The app is silent on it, not forgiving of it. |
| Depth is an estimate | A sensor estimate on a manikin, not a calibrated measurement. Use it to drive behaviour, not to certify a millimetre. |
| Placement changes it | Same technique, different phone position, different number. Standardise before comparing learners. |
| Surface matters | A manikin on a soft bed reads differently from one on the floor. Keep it constant within a session. |
| Manikin only | Never on a person. Not in a real arrest, not "just to see." |
A leaderboard is only fair when every station is identical. Strapped to the back of one hand and gripped in another's fist ranks phone position, not CPR.
Wear the sensor instead of placing it. Same free app, same score, same slot on your board — and the rhythm cue arrives through the wrist that is doing the compressing.
Apple Watch on watchOS 10 or later, paired to an iPhone on iOS 17 or later. Your iPad needs ACLSMED™ SIM 2.1.0 or later for watch students.
No second purchase, no separate download, no account, and no seat on your plan. The watch is part of the free companion app.
The moment the app sees a paired watch with the companion installed, it asks once per launch which device is measuring. No watch, no question — the picker never appears where the choice cannot be made.
One iPhone contributes exactly one stream — its watch or itself, never both. That is what stops a learner appearing twice on a six-slot board. Switching mid-class keeps the same slot and the same name.
Change it any time on the phone: the SENSOR ROLE button top-left, or Settings (gear) → APPLE WATCH.

| On screen | What it tells you |
|---|---|
| APPLE WATCH ACTIVE | Red watch glyph = the wrist hasn't opened the app yet. Green = it is streaming. |
| Watch Metronome | 110 bpm wrist taps and clicks, switched from here or from the watch itself. |
| SIM MONITOR LINK | Green = this phone is in your room. The FRAMES counter climbing is proof the chain is carrying data, not just connected. |
| SENSOR ROLE | Back to the picker — one tap to hand measurement back to the phone. |
In watch mode the wrist owns the run. The phone is a relay and a settings console; it never measures at the same time.

| Section | What to do with it |
|---|---|
| CONNECTION | Your iPad should be listed as ACLSMED SIM — monitor with a green tick. No row = this phone is not in your room, so neither is the watch. |
| STUDENT | The name you will read on the board. Fill this in before the first test — an unnamed learner shows as "Slot 3". |
| APPLE WATCH | Which device is measuring, the wrist metronome, and Watch status — Paired → Ready, open the app on your watch → Streaming. |
| METRONOME | The phone's own 110 bpm click. Independent of the wrist's. |
Read it before you touch anything else. Paired means the app is not open on the wrist. Ready means it is open but not measuring. Streaming means the problem is somewhere else.


| ● ACLSMED SIM CONNECTED | Green means the whole chain is up — phone reachable and your iPad receiving. Grey means the watch will still measure for the learner, but you will not see it. |
| The name | Pushed from the phone. Blank = nobody typed one in Settings → STUDENT. |
| START | Begins measuring — and asks your room to run its two-minute test (§ 04.08). |
| ♩ | Wrist taps and clicks at 110/min. Red = on. |
The watch carries the same manikin-only acknowledgement as the phone, and the same mark on every face. A worn device makes that boundary easier to blur — say it out loud anyway.




| Who presses | What happens | Who can end it early |
|---|---|---|
| You, on the iPad | The two-minute window opens for every connected station at once. | You only — a student device cannot end an instructor-started test. |
| A learner, on the watch or phone | Their START asks the room to run its test; your iPad opens the window for everyone. | That device — STOP finishes early and jumps to their debrief. |
| Six learners at once | First press wins. The rest are already in the test they just asked for — nobody restarts anyone's clock. | The one who started it. |
Overall score with a band — EXCELLENT · GOOD · KEEP PRACTISING · NEEDS WORK — then RATE · DEPTH · HANDS-ON out of 100. Scores, never centimetres.
The wrist's grade is sent with guaranteed delivery, so a watch that dimmed mid-test still lands its result on your board.
Student-started tests turn a queue into a station. You watch the board and coach; each learner runs their own two minutes when the manikin is free.

| Symptom | Fix |
|---|---|
| Watch says NOT CONNECTED | Open ACLSMED CPR on the phone and check it is in your room. The watch reports the whole chain, and the room end is the phone's. |
| Learner vanishes from the board mid-test | Their phone locked or they left the app. Keep it awake, on screen, beside the manikin. |
| Screen dims while compressing | Expected, not a fault. The wrist is face-down so watchOS dims it; the lamp stays on and readable and the data keeps flowing. |
| No compressions recorded | The watch must be on the wrist that is doing the compressions, not the free arm. |
| Board shows a slot but no name | Phone Settings → STUDENT. |
Reaching for a bag-valve mask, ventilating or gesturing does not inflate the count — the app rejects motion that isn't compression-shaped. A slow posture change during compressions is deliberately still counted; that's a rescuer adjusting, not an error.
The wrist and the sternum are different measurement sites. Both are honest estimates; they are not the same estimate. Within one comparison round, keep everyone on the same kind of sensor — and everything else identical: same manikin, same surface, same wrist.
Every limit in § 03.07 still applies — recoil is not measured, depth is an estimate, and it is a manikin trainer, never a patient device.
Three sessions that work out of the box, and the debrief that makes any of them stick.
| Time | Block | What you run |
|---|---|---|
| 0–5 | Orient | Show the Monitor. Point at SYNC, ANALYZE, SILENCE. They work the machine; you are the patient. |
| 5–15 | Rhythm drill | Step the catalog, call each cold. Fast, high-repetition recognition. |
| 15–25 | Skill isolation | One skill each: charge/shock · sync cardioversion · pace to capture. |
| 25–45 | Two MegaCodes | One shockable, one not — Pulseless VT, then PEA — Hypovolemia. Five-beat structure. |
| 45–60 | Debrief | Open CODE SUMMARY, walk the timeline. One keep + one change per learner. |
| Time | Block | What you run |
|---|---|---|
| 0–5 | Scope + setup | State manikin-only scope. Install, fill slots, standardise phone placement. |
| 5–10 | Baseline | Two-minute test. No coaching, board hidden. The honest starting point. |
| 10–18 | Coached round | Board visible. Coach live off the bars with the verdict words. Rotate compressors. |
| 18–25 | Re-test | Two minutes again — same placement, same surface. Compare to baseline. |
| 25–30 | Debrief | Sub-rings and focus badges. Name the limits. One target each for next time. |
Four tablets + phones on the compressors.
Learner first — "walk me through what you saw." They usually name their own error.
Then the data — timeline, shock count, compression scores. Timestamped and unarguable.
One change each — not five, stated as an action.
Close on competence — they remember the last thing you said.
| Symptom | Fix |
|---|---|
| Instructor and Monitor won't link | Same Wi-Fi · Bluetooth on · Airplane off. Settings → ACLSMED → Local Network → on. Relaunch Monitor first. |
| Worked yesterday, fails on hospital Wi-Fi | Guest/enterprise networks block device-to-device. Use a phone hotspot, or turn Wi-Fi off and pair directly. |
| Monitor sleeps mid-scenario | Auto-Lock → Never, on every tablet, before class. |
| Remote changes don't land | Check the CONNECTION panel; reconnect, then confirm with one rhythm change before resuming. |
| A phone won't take a CPR slot | All six full, or the phone is on another network. |
| Depth reads implausibly low/high | Re-seat the phone flat against the back of the hand, screen up. Keep the surface identical. |
| A watch learner never reaches the board | The chain runs watch → their iPhone → your iPad. Check the phone is in your room first; the watch cannot get there alone. § 04.01 |
| A watch learner drops out mid-test | Their phone locked or they switched apps. Keep it awake, in the app, beside the manikin. |
| Code Summary is empty | It is wiped on power-cycle — capture it before restarting. |
| Can't sign in on a new iPad | All seats held. Release the seat on the retired device first. |

| Button | What it is & what it does |
|---|---|
| DEFIB | Mode tab — manual defibrillation, the default: you set the energy, charge and deliver. |
| AED | Mode tab — the machine becomes an AED: analyze → advise → shock → a 2-minute CPR cycle → automatic re-analysis, looping like the real thing. |
| SYNC | Mode tab — synchronized cardioversion. A charged shock is held and fires on the R-wave, not the instant SHOCK is pressed. |
| ANALYZE | Mode tab — runs a rhythm analysis and advises whether a shock is indicated. |
| − / + | The energy dial — steps the selected energy down or up. |
| 120 · 200 · 300 · 360 | Energy presets — jump straight to a standard dose in joules. |
| CHARGE / DISARM | Charges to the selected energy. While charged the same key reads DISARM — press it to dump the charge safely without shocking. |
| SHOCK | Delivers the energy. Dead until the machine is charged; in SYNC it waits for the next R-wave. |
| PACER | Toggles transcutaneous pacing — the LED lights while pacing is live. |
| RATE − / + · mAMP − / + | Pacing rate (beats/min) and current (mA), stepped in fives. Capture on the ECG depends on enough output. |
CHARGE, SHOCK and AED stay dead until PADS is on. If the defib "isn't working," check the pads before anything else.
| Button | What it is & what it does |
|---|---|
| MEGA CODES | Loads one of the 33 scenarios — patient, opening rhythm and vitals — directly from the Monitor. |
| RHYTHM SELECT | Opens the rhythm catalog; step or jump to any of 60+ rhythms. |
| CODE SUMMARY | The code event log — shocks, drugs, energies, timings. Wiped on power-cycle — debrief or screenshot before restarting. |
| 12-LEAD | Reveals the scenario's 12-lead ECG. Zoom, SAVE and PRINT are live — print the tracing and hand it over for the debrief. |
| X-RAY | Reveals the scenario's chest film. |
| LABS | Reveals the scenario's lab panel. |
| MEDS | The drug and crash-cart reference. |
You can fire the 12-lead, X-ray and labs onto this screen from the Remote's Quick Actions the moment the team asks — or the team opens them here. Both screens stay in sync.
| Button | What it is & what it does |
|---|---|
| CPR | Toggles the CPR-quality overlay — it pulses at 110/min while compressions run. |
| PADS | Places or removes the defib pads. Pads must be on before CHARGE, SHOCK or AED will fire. |
| NIBP | Runs a non-invasive blood-pressure cuff cycle — inflates audibly, then chimes and posts the reading. |
| SILENCE | Mutes the audible alarm and reads SILENCED while live. It never stops the visual flash — and never fixes the patient. |
| ♩ Metronome top bar | Toggles a continuous ≈110/min compression click — no ventilation pause, compression-only guidance. |

Every key in this guide sits on the student-facing Monitor. You drive the patient from the Remote; the team operates the instrument.
ACLSMED™ SIM and ACLSMED™ CPR are education and simulation software for use with simulated patients and training manikins. Neither is a medical device; neither is intended for use on, or during the care of, a real patient; and neither replaces an accredited AHA course or your own clinical judgment. Clinical targets follow the AHA 2025 Guidelines for CPR and ECC.
