CodeRunner — Conditional Task Logic Reference

This document enumerates every condition that controls whether a task appears, is hidden, or changes behaviour in the CodeRunner app. It is intended for external validation of the clinical decision logic.

Primary sources:

src/data.ts — crNextTasks() task generation engine (lines 391–793)
src/utils.ts — state reconstruction and implicit field transitions (lines 17–199)
src/components/patient.tsx — task execution handlers and UI visibility guards

1. Task Generation Engine (`crNextTasks`)

crNextTasks() in src/data.ts inspects the reconstructed patient state s and returns an ordered list of recommended tasks. Tasks omitted from the return value are not shown to the user.

1.1 Pre-computed Derived Values

Before any pathway logic runs, several values are derived from the log:

shockable      = rhythm ∈ {VF, VT, VF_pVT}
aedDone        = doneTasks["get-aed"] === true
shockCount     = number of "shock" doses given
shockDoses     = timestamps of every shock
epiDoses       = timestamps of every epinephrine dose
amioDoses      = timestamps of every amiodarone dose
lidoDoses      = timestamps of every lidocaine dose
adenoDoses     = timestamps of every adenosine dose
atropineDoses  = timestamps of every atropine dose
lastLogAt      = timestamp of the most recent log entry
isRecent       = now − lastLogAt < 5 min
refTime        = isRecent || cpr.active ? now : lastLogAt
roscDone       = doneTasks["rosc"] === true

refTime is used instead of now for timing checks when the case has been idle for more than 5 minutes, preventing stale sessions from producing incorrect "medication due" states.

1.2 Initial Assessment Tasks

These appear before any pathway is entered to establish baseline information.

Task	Condition to show
`check-alert`	`alert === "?"`
`check-breath`	`breathing === "?"`
`check-pulse`	`pulse === "?" && !cpr.active && alert !== "Yes"`
`check-rate`	`pulse === "Yes" && rate === "?"`
`check-rhythm`	`pulse === "Yes" && rate ∈ {Fast, Slow} && rhythm === "?"`
`check-symptomatic`	`pulse === "Yes" && rate ∈ {Fast, Slow} && alert ∉ {No, Altered} && symptomatic === "?"`
`check-weight`	`type === "pediatric" && weightKg == null`

1.3 Cardiac Arrest Pathway

Entry condition: pulse === "No" || cpr.active

1.3.1 Always-shown task within pathway

Task	Condition
`get-aed`	`!aedDone`

1.3.2 Medication Readiness

Epinephrine (epi)

epiReady =
  epiDoses.length === 0
    ? (!shockable || shockCount >= 2)   // first dose: no shock needed unless shockable (requires 2 shocks)
    : refTime − epiDoses[last] >= 3 min // repeat: ≥ 3 min since last dose

Shown when: epiReady && !roscDone

Amiodarone (amio)

amioReady =
  amioDoses.length === 0
    || refTime − amioDoses[last] >= 5 min

Shown when: shockable && shockCount >= 3 && amioReady

Dose logic:

First dose → 300 mg
Repeat dose → 150 mg

Lidocaine (lido) (alternative antiarrhythmic)

lidoReady =
  lidoDoses.length === 0
    || refTime − lidoDoses[last] >= 5 min

Shown when: shockable && shockCount >= 3 && lidoReady

1.3.3 Pre-CPR State (`!cpr.active`)

Task	Condition
`shock`	`shockable && aedDone`
`start-cpr`	Always; label changes to "Single Rescuer" when `rescuers === "Two" && !aedDone`

1.3.4 CPR Paused State (`cpr.pausedAt` is set)

The paused state follows three mutually exclusive branches evaluated in order:

Branch 1 — ROSC detected (pulse === "Yes"):

Task	Notes
`rosc`	Only task shown in this branch

Branch 2 — Pulse or rhythm unknown (pulse === "?" || rhythm === "?"):

Task	Notes
`pulse-rhythm-check`	Shown unless shock-during-pause suppression applies
`resume-cpr`	Shown instead of `pulse-rhythm-check` when a shock was delivered in this pause window and `pulse === "No"`

Shock-during-pause suppression rule (src/data.ts lines 566–573): If lastShockDose > cpr.pausedAt && pulse === "No", skip the rhythm check and show resume-cpr directly (ACLS protocol: resume CPR immediately after shock).

Branch 3 — Pulse No, rhythm known (all other cases):

Task	Condition
`shock`	`shockable && aedDone`
`epi` / `amio` / `lido`	Per medication readiness rules (§ 1.3.2)
`reversible` (H's & T's)	Always — `recurring: true`
`airway`	`breathing !== "ETT"`
`access`	`!doneTasks["access"]`
`resume-cpr`	Always

1.3.5 CPR Running State (`cpr.active && !cpr.pausedAt`)

shockBeforeCpr = shockDoses.some(d => d < cpr.cycleStartAt)

Task	Condition
`pause-to-shock`	`shockable && aedDone && !shockBeforeCpr`
`pause-pulse-check`	`pulse === "Yes"` — label: "Pause CPR (Patient responsive)" if `alert === "Yes"`, else "Pause CPR (Pulse detected)"
`pause-pulse-check`	`rhythm === "NSR" && pulse !== "Yes"` — label: "Pause for Pulse Check" (same task ID, different label)
`pause-pulse-check`	`now − cpr.cycleStartAt >= 120 000 ms && pulse !== "Yes" && rhythm !== "NSR" && !(shockable && aedDone && !shockBeforeCpr)` — label: "Pause for Rhythm Check" (2-minute ACLS cycle)
`airway`	`breathing !== "ETT"`
`access`	`!doneTasks["access"]`
`epi` / `amio` / `lido`	`pulse === "No" && rhythm !== "?"` — per medication readiness rules (§ 1.3.2)
`reversible` (H's & T's)	Always — `recurring: true`

1.3.6 Rescuer confirmation (all cardiac arrest states)

check-rescuers is evaluated outside all three CPR sub-states and can appear even before CPR starts:

Task	Condition
`check-rescuers`	`rescuers === "?" && breathing !== "ETT" && epiDoses.length === 0`

1.4 Respiratory Arrest Pathway

Entry condition: breathing === "No" && pulse !== "No" && !cpr.active

Task	Condition
`opioid-reversal`	Always
`rescue-breaths`	`pulse === "Yes"` — `recurring: true`, `kind: "critical"`

1.5 Pacing Wean

Condition: rate === "Fast" && given("pace") % 2 === 1

The modulo-2 check determines if pacing is currently active (odd start/stop count = running).

Task: wean-pacing — recurring: true

1.6 Tachycardia Pathway

Entry condition: pulse === "Yes" && rate === "Fast" && symptomatic === "Yes"

These tasks appear for all rhythms when the entry condition is met:

Task	Condition
`ecg`	Always
`access`	`!doneTasks["access"]`

NSR sub-pathway (rhythm === "NSR"):

Task	Condition	Recurring	Popup
`sinusTachDiff`	Always	Yes	`sinusTachDiff`
`sepsisBloodCx`	`sepsisSuspected === "Yes"`	No	—
`sepsisAbx`	`sepsisSuspected === "Yes"`	No	—
`sepsisLactate`	`sepsisSuspected === "Yes"`	No	—
`sepsisIVF`	`sepsisSuspected === "Yes"`	No	—

The sinusTachDiff popup shows a two-section differential: Shock Causes (sepsis, hemorrhage, PE, anaphylaxis, transfusion reaction, tension pneumo, tamponade, neurogenic) and Other Causes (hypoxia, pain/anxiety, fever, hyperthyroidism, drug effect).

SVT sub-pathway (rhythm === "SVT"):

adenoGiven = adenoDoses.length

Task	Condition
`adenosine`	`adenoGiven < 3` — dose: 6 mg (1st), 12 mg (2nd+)
`cardiovert`	`rhythm ∈ {AF, SVT, WideTach}`

Wide tachycardia sub-pathway (rhythm === "WideTach"):

amioReadyTach =
  amioDoses.length === 0
    || refTime − amioDoses[last] >= 5 min

Task	Condition	Dose
`amio`	`amioReadyTach`	150 mg over 10 min (both 1st and repeat doses — slower rate than arrest amio)
`cardiovert`	`rhythm ∈ {AF, SVT, WideTach}`	—

AF sub-pathway (rhythm === "AF"): only cardiovert shown.

1.7 Bradycardia Pathway

Entry condition: pulse === "Yes" && rate === "Slow" && symptomatic === "Yes"

atropineReady =
  atropineDoses.length === 0
    || now − atropineDoses[last] >= 3 min

Task	Condition
`access`	Always
`atropine`	`given("atropine") < 3 && atropineReady`
`pace`	`given("pace") === 0`
`dopamine`	`given("dopamine") === 0`

1.8 Altered Alertness Pathway

Entry condition: alert === "Altered" && pulse !== "No"

Task	Condition
`glucose`	`glucose === "?"`
`d50`	`glucose === "Low"`
`check-stroke-sx`	`strokeSx === "?"`
`fast`	`strokeSx === "Yes"`
`ct`	`strokeSx === "Yes"`

1.9 Choking Pathway

Entry condition: breathing === "Choking"

Task	Condition	Recurring
`choking-cycles`	Always	Yes
`reassess-responsiveness`	Always	Yes

1.10 Task Filtering and Priority Sort

After all pathways generate their task lists:

filtered = tasks.filter(t => t.recurring || !doneTasks[t.id])

Recurring tasks always remain visible. Non-recurring tasks are hidden once doneTasks[taskId] === true.

Priority order (lower index = higher priority, src/data.ts lines 327–375):

Cardiac arrest actions: shock, cardiovert, pause-to-shock, start-cpr, rosc, resume-cpr, pause-pulse-check, pause-nsr-check, pulse-rhythm-check
Respiratory arrest: rescue-breaths, opioid-reversal
Cardiac support: get-aed, airway, epi, amio, lido, access, reversible, check-rescuers, meds-support
Tachycardia: ecg, adenosine
Bradycardia: atropine, pace, dopamine, wean-pacing
Altered/stroke: glucose, d50, check-stroke-sx, fast, ct
Choking: choking-cycles, reassess-responsiveness
Assessment: check-alert, check-breath, check-pulse, check-rate, check-rhythm, check-symptomatic
Lowest: check-weight

Tasks not found in the priority list are appended after all prioritised tasks, preserving their relative order.

2. State Reconstruction — Implicit Field Transitions (`src/utils.ts`)

The patient state is fully reconstructed by replaying the log. Several status field changes trigger automatic secondary changes.

2.1 Alert field changes

New `alert` value	Secondary effect
`"No"` or `"Altered"` (from `"Yes"`)	`pulse = "?"`
`"Sedated"`	Only set implicitly when `breathing` is set to `"ETT"`

2.2 Breathing field changes

New `breathing` value	Secondary effect
`"ETT"`	`alert = "Sedated"`

2.3 Pulse field changes

New `pulse` value	Secondary effect
`"Yes"`	`rhythm = "?"`
`"?"` or `"No"`	`rate = "?"`
`"No"`	Also `rhythm = "?"`

2.4 Rate field changes

Trigger	Secondary effect
`rate` changes to a new value	`rhythm = "?"`

2.5 Rhythm field changes

New `rhythm` value	Secondary effect
`VT`, `VF`, `VF_pVT`, `PEA`, or `Asystole`	`pulse = "No"`

2.6 Shock delivery

Giving a shock always resets rhythm = "?".

2.7 Post-reconstruction overrides (applied after log replay)

Alert "Yes" override:

if alert === "Yes" → force pulse = "Yes"

Symptomatic auto-promotion:

if pulse === "Yes" && rate ∈ {Fast, Slow}:
  if alert ∈ {No, Altered}: symptomatic = "Yes"   // patient cannot self-report
else:
  symptomatic = "?"                                 // reset when not applicable

2.8 Medication type validation

Medications are categorised as either discrete or continuous:

Category	Medications	Valid `action`
Discrete	epi, amio, lido, adenosine, atropine, d50, naloxone	`"give"`
Continuous	dopamine, norepinephrine, vasopressin, procainamide, pacing (`pace`)	`"start"` / `"stop"`

Log entries that use the wrong action for a medication type are ignored during reconstruction.

2.9 CPR state transitions

Log event	State change
`cpr.start`	`cpr.active = true`, `cpr.cycleNumber = 1`, resets `pulse = "?"`, `rhythm = "?"`, sets `cycleStartAt`
`cpr.resume`	`cpr.cycleNumber++`, clears `pausedAt`, resets `pulse = "?"`, `rhythm = "?"`
`cpr.pause`	Sets `pausedAt` timestamp, preserves `active = true`
`cpr.sync`	Updates metronome anchor timestamp
`cpr.rosc` / `cpr.end`	`cpr.active = false`, clears `pausedAt`

2.10 Task completion side effects

Task completed	Side effects
`airway`	`breathing = "ETT"`, `alert = "Sedated"`
Any other task	`doneTasks[taskId] = true`

3. Medication Active-State Logic (`src/components/patient.tsx`)

Continuous medications use start/stop log entries. Active state is determined by:

isActive = isContinuous && count % 2 === 1

Odd count (1, 3, 5…) → medication is currently running
Even count (0, 2, 4…) → medication is currently stopped

Pacing special case (on each pace log entry):

If pacing is being stopped (isActive before the stop), or if rate !== "Fast": reset rate = "?" and rhythm = "?"

Adenosine/Atropine special case (on each give entry):

Immediately reset rate = "?" and rhythm = "?" (patient re-assessed after bolus)

4. CPR Guidance Text Conditions

getCprGuidance() in src/components/patient.tsx determines the compression/ventilation ratio label displayed during CPR:

Condition	Displayed guidance
`breathing === "ETT" && type === "pediatric"`	`"Continuous · 1 breath/2-3s"`
`breathing === "ETT" && type !== "pediatric"`	`"Continuous · 1 breath/6s"`
`rescuers === "Team"`	(empty — team manages own ratio)
`type === "pediatric" && rescuers === "Two"`	`"Ratio = 15:2"`
All other cases	`"Ratio = 30:2"`

5. CPR Cycle Timer Alert Thresholds

The CPR overlay tracks elapsed time within the current cycle:

elapsed = cpr.active && !cpr.pausedAt
  ? Date.now() − cpr.cycleStartAt
  : cpr.pausedAt ? cpr.pausedAt − cpr.cycleStartAt : 0

near = !paused && elapsed >= 1 min 45 s   // warning state
past = !paused && elapsed >= 2 min        // alert state; triggers auto-collapse + 2-tone beep

6. Status Field Visibility Guards

The following table summarises when each editable status field is rendered in the UI:

Field	Visible when	Disabled when
`alert`	Always	—
`breathing`	Always	—
`pulse`	`alert !== "Yes"`	`cpr.active && !cpr.pausedAt`
`rate`	`pulse === "Yes"`	—
`symptomatic`	`pulse === "Yes" && rate ∈ {Fast,Slow} && alert ∉ {No, Altered}`	—
`rhythm` (arrest options)	`pulse !== "Yes" && (pulse === "No" \|\| cpr.active) && (aedDone \|\| cpr.active)`	—
`rhythm` (pulse options)	`pulse === "Yes" && rate !== "?" && rate !== "Normal"`	—
`rescuers`	`(pulse === "No" \|\| cpr.active) && breathing !== "ETT" && epiDoses.length === 0`	—
`weightKg`	`type === "pediatric"`	—
`glucose`	`alert === "Altered" && pulse !== "No"`	—
`strokeSx`	`alert === "Altered" && pulse !== "No"`	—
`sepsisSuspected`	`pulse === "Yes" && rate === "Fast" && rhythm === "NSR"`	—

Rhythm option sets by context:

Arrest rhythm options: VF/VT, PEA, Asystole, NSR
Fast pulse options: NSR, SVT, AF, Wide VT, TdP
Slow pulse options: NSR, Sinus Bradycardia, 1° AVB, 2° AVB, 3° AVB
Normal pulse options: NSR, AF

sepsisSuspected resets to "?" whenever rate changes (alongside rhythm reset).
