It can be edited to add new drugs and dilutions. Drugs are added this way: - one drug per line - each argument is separated by a comma - the arguments are as follows: Name,Quantity,QtyUnitIndex,Volume,defaultQtyUnitIndex,defaultTimeIndex,Info for QtyUnitIndex and defaultQtyUnitIndex: 0=ng, 1=mcg, 2=mg, 3=g, 4=U for defaultTimeIndex: 0=min, 1=hr, 2=12hr, 3=24hr Example: Amiodarone,600,2,50,2,3,Loading dose: 5mg/kg over 20 min.

Formula:
index = reti * (hct/45) / CF

Units:
CF = maturation correction factor.
When the marrow is greatly stimulated, marrow reticulocytes enter the circulation prematurely. The index must be corrected to account for the longer circulation time of those 'shift reticulocytes'. The correction factor depends on the severity of the anemia.
Hct 41%-50% (CF=1)
Hct 30%-40% (CF=1.5)
Hct 20%-39% (CF=2)
Hct 10%-19% (CF=2.5)

Clinical use:
Adjusts reticulocyte count for hematocrit. An index > 3 shows a normal marrow response to anemia. An index < 2 is an inadequate response to anemia. With a normal hematocrit, an index of 1 is normal.

Formula:
MCV = 1000 * Hct / RC
MCH = 10 * Hb / RC
MCHC = Hb / Hct

Units:
Hb [g/dL], Hct %, RC [millions/L],

Clinical use:
Red blood cell indices reflect erythrocyte volume and hemoglobin concentration in the erythrocyte.
MCV: mean cell volume
MCH: mean cell hemoglobin
MCHC: mean cell hemoglobin concentration

Clinical use:
This score estimates the risk of life-threatening complications or death in patients with acute pancreatitis.

If the delta gap is significantly positive (greater than +6), a metabolic alkalosis is usually present because the rise in AG is more than the fall in HCO3.
Conversely, if the delta gap is significantly negative (less than -6), then a hyperchloremic acidosis is usually present because the rise in AG is less than the fall in HCO3.
Delta gap is sometimes referred to as Delta-Delta.

    Formulas:
    PAO2 = FiO2*(pAtm-pH2O)-pCO2/RQ
    pAtm = 760*exp(-alt/7000)
    Gradient = PAO2 - paO2
    Ratio = PaO2 / PAO2

    Units:
    FiO2=fractional inspired oxygen
    pAtm=atm. pressure [mmHg]
    alt = altitude [m]
    pH2O = 47 [mmHg] at 37 [C]
    RQ = respiratory quotient
    paO2 = arterial press. of O2
    pCO2 = arterial press. of CO2
    both in [mmHg]

    Clinical use:
    Measure of efficiency of blood oxygenation. Gradient affected by ventilation / perfusion or diffusion abnormalities but unaffected by hypo- or hyperventilation.

    The normal A-a gradient varies with age and ranges from 7 to 14 [mmHg] when breathing room air.
    The lower limit of normal of A-a ratio is 0.77-0.82.

    Formula:
    EABL = (Hct_start - Hct_allow)*BV/Hct_start
    BV = 0.07 [L/kg] (blood volume)

    Units:
    Weight [kg], Hct %, EABL [L]

    Clinical use:
    Estimated amount of blood a patient can loose before reaching a critical level of hemoglobin during anesthesia.

    Formula:
    As the value of years and months is variable in the calendar, a mean value of 365.2422 days per year and 30.4368 days per month is used for computing the age in years and months. Age in weeks and days is perfectly accurate.

    Clinical use:
    This formula is useful for plotting heights and weights on growth charts. It's meant for pediatric use and will give unpredictable results for older patients.

    Formula:
    ANC = WBC * (Polys + Bands) / 100

    Units:
    Polys, Bands %
    ANC, WBC [cells/mm³]

    Clinical use:
    Neutropenia if ANC < 1500 [c/mm³]
    Severe < 500 [c/mm³]
