    Ventilator Settings: EMS Cheat Sheet & Guide

    Ventilator settings for EMS and transport crews: IBW, tidal volume, rate, PEEP, and FiO2 with plain-text math, a cheat-sheet table, and worked examples.

  • Ventilator Settings

    Dead Space Ventilation: Types, EtCO2, and Rate

    Dead space ventilation is the share of each breath that never reaches gas exchange. Compare anatomic, alveolar, and circuit dead space, and read the EtCO2 gap.

    Devine Formula: Ideal Body Weight for the Vent

    The Devine formula: 50 kg for men or 45.5 kg for women, plus 2.3 kg per inch over 5 feet. Where it came from, and why adult vent settings run on it.

  • Ventilator Settings

    Driving Pressure on a Ventilator: Under 15

    Driving pressure on a ventilator is plateau minus PEEP, kept under 15 cm H2O per StatPearls. How to read it, why total PEEP matters, and how to bring it down.

  • Ventilator Settings

    Initial Ventilator Settings After RSI for EMS

    Initial ventilator settings after RSI: the first 10 minutes on the vent, why the weight basis switches from actual to ideal, and what to verify next.

    Ventilator Respiratory Rate Setting, Explained

    The ventilator respiratory rate setting is a floor, not the delivered rate. Compare set and total rate, spot patient triggering, and protect exhalation in COPD.

  • Ventilator Settings

    I:E Ratio on a Ventilator: Normal vs COPD

    I:E ratio on a ventilator: 1:2 to 1:3 with normal lungs, 1:4 or longer in COPD and asthma. How to calculate it, change it, and keep auto-PEEP off.

  • Ventilator Settings

    Minute Ventilation Formula: Ve = Vt x RR

    The minute ventilation formula, Ve = Vt x RR, worked with sourced values, then run backward to derive respiratory rate from a Ve target. Free app included.

    Tidal Volume Calculator: Devine IBW Chart

    A tidal volume calculator built on the Devine formula and ideal body weight, with a full height-to-Vt chart, worked examples, and a free iOS/Android app.

    RSI Medications: Adult Doses and Field Workflow

    RSI medications for adult patients: induction agents, paralytics, mg/kg starting doses on actual body weight, and the post-intubation sedation handoff.

    Endotracheal Tube Cuff Pressure and Altitude

    Endotracheal tube cuff pressure for a ventilated adult: the 20-30 cm H2O window, how to check it with a manometer, and why it climbs at altitude in flight.

    Ventilator Alarms: Causes and Field Fixes

    Ventilator alarms for EMS and transport crews: what each alarm means, the causes to check in order, and why the fix is at the patient, not the vent.

  • Ventilator Troubleshooting

    Plateau Pressure Normal Range: Under 30 cm H2O

    Plateau pressure normal range for a ventilated adult: at or under 30 cm H2O per ARDSNet. How to measure it with an inspiratory hold and what a high Pplat means.

  • Ventilator Troubleshooting

    High Pressure Alarm on a Ventilator: What to Do

    A high pressure alarm on a ventilator means something is resisting the breath. The checks in order, the hold that splits tube from lung, and transport causes.

  • Ventilator Troubleshooting

    Post-Intubation Checklist for EMS Transport

    Post-intubation checklist for EMS: the tube, circuit, settings and sedation checks to run before you move an intubated adult, and again after every move.

  • Ventilator Troubleshooting

    Post-Intubation Hypoxia: A DOPES Walkthrough

    Post-intubation hypoxia, worked in order: disconnect and bag first, then DOPES, with the field checks a two-person crew can actually run in a moving truck.

  • Ventilator Troubleshooting

    Post-Intubation Ventilator Management for EMS

    Post-intubation ventilator management for EMS and transport: what to verify after the tube, which numbers to recheck, and when a change means trouble.

    Normal Ventilator Values: EMS Reference Card

    Normal ventilator values for adult patients: tidal volume, PEEP, plateau and peak pressure, EtCO2, ABG and VBG ranges, and the RASS scale, each with its source.
