Medicalc 1.0                                        by Vernon W. Huang, MD                                         huangv@well.sf.ca.us                                            CIS: 74127,2023If you are using a previous version of Medicalc please manually delete it before installing this version.DISCLAIMER:  This program comes with no warranty or guarantees of performance or accuracy whatsoever.

Registration entitles you to free upgrades in the 1.xx versions as I increase the numbers of formulas supported.  Registered users will also be able to have more than 25 entries in the Pediatric and Stat Med references.Registered users of 1.xx will also receive a discount toward upgrading to version 2.0 which will incorporate the ability to save patient lab values.  I have no idea when 2.0 will be done.Registered users will also receive NTK source code adding to the ÒsoupsÓ that medicalc accesses.  With this code and the Newton Toolkit one can use the computer to enter new medications.WHAT IT DOES:  Medicalc calculates values pertinent to patient care using recognized algorithms.  It can save you time in the hospital and help you to rationalize the purchase of the your Newton MessagePad.FEATURES: ¥Chem-7 analysis--calculates osmolality, anion gap, estimated creatinine clearance and, in hypernatremic patients, free water deficit.1) Osmolality = Na*2 + Glu/18 + BUN/2.82) Anion Gap = Na - (Cl+CO2)3) Estimated Creatinine Clearance = [(140-age)(Weight)] / (72 x Creatinine)4) Free Water Deficit = 0.6 x Na x Weight / 140¥BSA--Calculates body surface area.BSA = Wt(kg)^0.425 * Ht(cm)^0.725 * 1000¥ANC--Calculates Absolute Neutrophil CountANC = WBC Count * %PMN's ¥PedsRx and STAT Rx--Accesses two user configurable drug references.  Each of these references shows generic name, trade name, indications, dosing information, formulations and notes.  The users has the choice to view sorted entries by generic or trade name.The drug references also let the user set a default guideline for dosing medication based on weight.  Note that the number saved is in mg/kg/dose.¥IV CALC:  A handy calculator for figuring out what rate to set an IV at to deliver medication based on mg/min, mg/hr, mg/kg/min, mic/kg/min, etc.  Check it out to see what IÕm talking about.Using Medicalc:  Using Medicalc is fairly self explanatory.  Simply push on the desired buttons and enter text in the blank lines.  When adding or editing a drug reference I suggest double tapping on the fields in the screen and using the pop up keyboard to enter drug names since these will not be found in the NewtonÕs dictionary.New drug entries are saved in the default user store.  I strongly recommend using Medicalc and storing entries on a PCMIA card.  As Medicalc consumes almost 70k of memory, storage on the NewtonÕs internal memory is NOT recommended.Of course the best way to enter new drug information is to become a Newton developer and register Medicalc to receive the MediSoup NTK source code.MEDISOUP: This Newton app installs a few demo medications that can be accessed from Medicalc.  The information in Medisoup is demonstratory only and comes with no warranties or guarantees of accuracy whatsoever.you can run Medisoup either before or after running Medicalc for the first time.Medisoup can be deleted from the Newton once it has been run.Features to be added in future versions 1.xx:¥ ACLS and PALS algorithms with pediatric dosage by weight calculated.¥ Pediatric maintenance fluids.¥ Other formulas that users demand that arenÕt too hard to implement.CONTACTING THE AUTHOR:  Please send your comments, complaints, desires to me via e-mail or at the above address.  If you have a database of medications, I would be particularly interested in hearing from you.ENJOY!Vernon W. Huang, MDOctober 30, 1993
