Blue is a simple drug calculator for Palm OS handhelds. It is designed for rapid
acquisition of medication doses in a resuscitation setting.
The calculator is primarily designed for pediatric dosing based
on age and weight, but it contains adult doses as well. The
design allows the user to quickly see all the medications relevant
to a specific task on one screen.
program is divided into 5 sections. Rapid Sequence, Tubes and
Lines, ACLS, Neurological, and Burns. Each section contains
information relevant to the resuscitation of that particular
patient/situation. Only commonly used medications were included.
It is likely that some users will find that an agent they commonly
use is not present. If this is the case, please email me at
firstname.lastname@example.org. If enough people request a
specific drug, I will modify the application to include/replace
a certain agent. By design, the program does not scroll. The
purpose was to create a single screen, packed with information--
yet still legible and useful.
begin, pull down the AGE selector. Selecting an age will insert
an estimated weight into the WEIGHT box located at the top
of the screen. Weights are based on the CDC: National Health
and Nutrition Exam Survey, May 2000. For a given age, the 50th
percentile weights were averaged for both male and females
to come up with an estimate. The Tubes and Lines section uses
length to estimate tube sizes. Lengths are estimated using
the same data set, and are composed of averages of 50th percentile
lengths for both male and female patients.
you wish to enter a patient weight, click the red "C" to
clear the weight box. Then place your cursor in the weight
box, and manually enter a weight using graffiti, or the PALM
keyboard. If you are entering a weight in (lb), make sure to
click the (lb) key prior to entering the weight. All calculations
are in kilograms. All weights will be converted to kilograms.
If the selector is set to (lb), you will see the weight in
pounds, but the medication doses are appropriately calculated
in kilograms. You can also use the kg/lb buttons as a rapid
converter-- kg <--> lb.
doses are based on a review of several prescribing references.

Explanation for more information.
section contains drugs used in rapid sequence intubation. It
is divided into pre-medication, induction, and paralytics.
Many of the medications are not approved for certain age groups.
In these cases, Code Blue will show "N/A". Many medications
also have different dosing regimens for different ages and
weights. The program takes this into account and modifies the
calculations and corresponding medication label.
section is a reproduction of tape based equipment estimators.
References state that estimation of tube and line sizes is
more accurately estimated based on patient length, rather than
weight. This intuitively makes sense. Code Blue still attempts
to estimate weight based on age. It also attempts to estimate
length based on age. To help the user more accurately estimate
tubes and lines, the corresponding published lengths are presented
with the tube and line sizes.
section presents commonly used ACLS medications. It includes
vasopressors, and anti-arrhythmics. Like the other medication
sections, all dosing ranges are age based, and change according
to the weight and age selected. See the Drug Dosing section
for details on the ranges selected.
section is useful primarily for head injuries, spinal cord
and neurological traumas. It contains dosing for diuretics,
and steroids used in the initial resuscitation stages of a
neuro trauma. It also contains a GCS scale, with pediatric
equivilents of the adult scale.
final section, Burns provides the user with a pediatric friendly
Rule of 9's calculator. Because pediatric proportions are different
than adults, estimates of body surface area based on an adult
scale will not represent the true injury. This calculator estimates
pediatric proportions based on weight/age. Simply click on
the detailed body parts to include them in the calculation.
Enter the patient's weight at the top, or select the patient's
age from any of the previous screens. The patient's BSA is
calculated. To the right of the Weight is the Parkland Formula's
estimate for fluid replacement.
formula: 4 x BSA x wt(kg)
