Here you are:

  • Add a macro inside file config.edn , inside macros{} :
    :wetflag

  • The code below requires having kits inside file custom.js .
  • Inside page WetFlag in Logseq, put the following code in a javascript code-block:
    function weightFromAge(age){
    if (age < 1.5) return 0.5 * age + 4
    if (age < 5.5) return 2 * age + 8
    if (age < 13.5 ) return 3 * age + 7
    if (age < 16.5) return 4 * age + 2
    return 70
}
  
logseq.kits.wetflag = function wetflag(table){
    const dataAge = Number(table.dataset.age)
    const age = isNaN(dataAge) ? 1 : dataAge
  
    const dataWeight = Number(table.dataset.weight)
    const weight = isNaN(dataWeight) ? weightFromAge(age) : dataWeight
  
    const result = {
        age,
        weight,
        energy: 4 * weight,
        ETT_ID: age / 4 + 4,
        ETT_length_oral: age / 2 + 12,
        ETT_length_nasal: age / 2 + 15,
        fluid_medical: 20 * weight,
        fluid_trauma: 10 * weight,
        lorazepam: 0.1 * weight,
        adrenaline: 0.1 * weight / 1,
        glucose: 2 * weight
    }
  
    for (const id in result) {
        table.querySelector(`#${id}_wetflag`).textContent = result[id]
    }
}
  • Now you can use it like {{wetflag 12, 40}}
    • Or omit the weight, e.g. {{wetflag 12}}
  • Though the calculations look doubtful.
  • It renders like this:
