  1. Formula idea for cardiology - VO2

    Hi, great app! One suggestion:

    The Fick cardiac output is currently calculated with an assumed/entered VO2 numerator. Many cardiologists use the LaFarge formula & BSA to estimate VO2; this would be a helpful added calculator to have.

    LaFarge:

    Males: VO2/BSA (mL/min/m2) = 138.1 − (11.49× ln age) + (0.378×HR)

    Females: VO2/BSA (mL/min/m2) = 138.1 − (17.04× ln age) + (0.378×HR)

    BSA best estimated by Mosteller equation which is already in MedCalc.

    Thanks!

  13. Sauerstoffpartialdruck Altersanpassung sowie Anpassung pO2 bei Hypoxie

    Guten Morgen. Zunächst ersteinmal: tolles Programm.
    Jetzt habe ich als Pneumologe noch zwei Ideen:
    1. Altersanpassung Sauerstoffpartialdruck
    pO2 (mmHG)=100-(0,26xAlter)
    2. Umrechnungsformel pO2 bei Hypoxie
    pO2korr=pO2ist-1,66x(40-pCO2).

    Wäre toll, vor allem letzteres wird oft vergessen.

  15. Improvement of the Obstetric Wheel

    I purchased this App to make use of Obstetric wheel among others. I would like to recommend that when patients are stored with obstetric information using LMP, when it is loaded to give you an updated Gestational Age (GA), I mean current GA not same age it was when the data was entered. The age updates automatically so please make the gestational age also update automatically also give the option to arrange from lower GA to higher GA or vice versa. It makes easier to manage patients at a glance. I would very much appreciate it if could be done.

  20. Improvement to allowable blood loss formula

    The allowable blood loss formula doesn't address adjustments for obese patients, who may have a blood volume of 40 ml/kg or lower. It would be wonderful if the MedCalc formula incorporated the results of "Estimating Blood Volume in Obese and Morbidly Obese Patients," Lemmens et al Obesity Surgery 2006 Jun;16(6):773-6. (http://www.ncbi.nlm.nih.gov/pubmed?term=estimating%20blood%20volume%20in%20obese%20and%20morbidly%20obese%20patients)

    Thank you for making and maintaining MedCalc - it is a fantastic, easy-to-use resource for practice and teaching!
