nitrox-lab-core v2.0.4

nitrox-lab-core

Usage

npm i nitrox-lab-core

import { NitroxLabCore } from 'nitrox-lab-core';

const nx = new NitroxLabCore();

const mod = nx.calcMOD(0.32, 1.4); // 33.75

Settings

• settings (optional)
  • units (optional) - depth and pressure units (METRIC | IMPERIAL), default: METRIC
  • defaultPpO2Max (optional) - default maximum $O_{2}$ fraction, default: 1.4

    import { NitroxLabCore, Units } from 'nitrox-lab-core';

    const settings = {
        units: Units.METRIC, // optional, METRIC | IMPERIAL
        defaultPpO2Max: 1.4 // optional
    };
    const nx = new NitroxLabCore(settings);

MOD

calcMOD(fO2, ppO2Max);

• fO2 - $O_{2}$ fraction
• ppO2Max - maximum $O_{2}$ partial pressure

    const mod = nx.calcMOD(0.32, 1.4); // 33.75

Best mix

calcBestMix(depth, ppO2Max);

• depth
• ppO2Max - maximum $O_{2}$ partial pressure

    const bestMix = nx.calcBestMix(30, 1.4); // 0.35

Top off

calcTopOff(options);

• options
  • currentMix
    • fO2 - current mix $O_{2}$ fraction
    • p - pressure
  • topOffMix
    • fO2 - top off mix $O_{2}$ fraction
• targetPressure - end pressure

const options = {
    currentMix: {
        fO2: 0.32,
        p: 100
    },
    topOffMix: {
        fO2: 0.21
    },
    targetPressure: 220
};

const topOffResult = nx.calcTopOff(options); // 0.26
