Education-only calculator guides

Clinical Calculators

Grouped by sizing, medications, pediatrics, and ventilator setup. These are training aids; replace defaults with your ED, anesthesia, ICU, and pediatric protocols before clinical teaching use.

Protocol lockout: These calculators intentionally show formulas and ranges. They should not be used as a stand-alone bedside dosing tool until reviewed, approved, and localized by your clinical leadership.

Group 1

Sizing

Tube, depth, blade, predicted body weight, and equipment preparation.

Adult ETT / equipment sizing quick prep

Prepares primary tube plus one smaller and one larger; always confirm with waveform EtCO2, depth, bilateral exam, and imaging when appropriate.

Predicted Body Weight

Uses the common ARDSNet/NIH PBW equation for lung-protective tidal-volume calculations.

Pediatric ETT size + depth

For children ≥1 year, estimates uncuffed ETT as age/4 + 4 and cuffed ETT as 0.5 mm smaller. Stage ±0.5 mm tubes.

Supraglottic rescue size guide

Device-specific sizing varies. Use this only as a staging prompt and check the manufacturer’s chart for the device in your airway cart.

Group 2

Meds

Adult RSI, shock-sensitive induction, paralytic, and post-intubation sedation guides.

Adult RSI medication guide

Includes induction and paralytic ranges. It is not an order set.

Post-intubation sedation guide

Hard stop: analgesia/sedation should be ready before paralytic administration whenever feasible.

Post-intubation crash risk

Risk prompts selected: 0

Attempt troubleshooting prompt

After a failed attempt, choose the change before trying again:

Medication handoff builder

Creates the exact verbal sequence you want the room to hear before paralysis.

Use with the adult/peds calculators; do not let post-intubation sedation become an afterthought.

Group 3

Peds

Pediatric airway staging and intubation medication training ranges.

Pediatric intubation meds

Use measured or length-based weight when available. Round thoughtfully and follow pediatric emergency medication standards.

Pediatric atropine helper

Traditional teaching includes 0.02 mg/kg with minimum and maximum dose constraints; local PALS/PED pharmacy policy should control display values.

Pediatric initial vent guide

Tidal volume is a starting guide; titrate to lung mechanics, gas exchange, disease physiology, and pediatric ICU/RT guidance.

Peds airway prebrief

Copy a pediatric airway-specific briefing line for simulation or teaching.

Peds color-zone airway guide

Approximate Broselow-style airway zone helper for education. Use your actual Broselow/length-based tape and local pediatric standards as the bedside source of truth.

Group 4

Ventilator

Initial adult ventilation, ARDS-style VT targets, minute ventilation, and obstructive-physiology prompts.

Adult initial ventilator settings

Default guide: PBW-based VT 4–8 mL/kg, common starting RR range, PEEP/FiO2 prompt, and plateau-pressure reminder.

Minute ventilation estimator

Useful in severe acidosis when pre-intubation minute ventilation is high and post-intubation under-ventilation can be dangerous.

Obstructive physiology I:E prompt

For asthma/COPD: prioritize long expiratory time, avoid breath stacking, and reassess flow-time waveform.

Oxygenation escalation prompt

Use as a structured reminder, not an automated protocol.

  1. Confirm tube, waveform EtCO2, depth, and circuit.
  2. Increase FiO2 first for immediate rescue, then titrate PEEP deliberately.
  3. Check plateau pressure / driving pressure when available.
  4. Escalate early: RT, ICU, proning/paralysis/ARDS pathway as appropriate.

Driving pressure + static compliance

Requires an inspiratory hold/plateau measurement. Use with RT/ICU workflow.

Vent scenario builder

Use this after the initial settings to force a physiology-specific second pass.

Calculator reference anchors to localize

Use these as starting references while converting the calculator guides into your local protocol display.
