LabVIEWTM
Software Programs for Clinical, Basic and Applied Physiology
Since 2003 I have been teaching myself programming skills using LabVIEW, a data
flow programming language from National Instruments (NI). Since 2004, I
have been using such programming to acquire and perform post-acquisition data
processing on almost all of my research projects, encompassing EMG, breath by
breath indirect calorimetry, heart rate variability, computations of metabolite
and reaction proton dissociation constants, 31P
MRS data processing, incremental exercise protocol development, and modeling
metabolism to quantify the skeletal muscle metabolic proton load.During my national and international travels associated with scientific speaking,
numerous colleagues and conference participants have inquired as to how they
could acquire copies of my programs. Well, your opportunity to purchase my
software has become a reality.
The software is now available for purchase at www.NEXSIS.org.
Below I provide short descriptions of the programs. Click on the icon for each program to retrieve a pdf
document detailing the features of the program and user instructions.
Note that to use the programs, you must download the LabVIEW Runtime Player (free with program purchase).
The LabVIEW Runtime Player is a free application from NI
that allows users to run executable programs written in LabVIEW.

Breath-by-breath VO2 Data Processing
|
 |
Allows the user to select and apply either a time, breath or a low pass
digital filter to decrease variability in all data from
indirect calorimetry. In addition, the program could be used for any
data set where a valid means to decrease variability is required. The program also allows you to detect
metabolic thresholds. You can import data as text (.txt) files
containing just numbers or numbers and words (strings), and also
delete and/or rearrange columns and/or rows. |

Incremental Exercise Protocol Development
|
 |
Performs the computations necessary to
guarantee linear increments in VO2 demand
for each stage of incremental exercise protocols for treadmill walking,
treadmill running, cadence independent cycle ergometry, and cadence
dependent cycle ergometry. Protocol
features such as total duration, stage duration, anticipated VO2max and
start intensities are entered by the user to initiate calculations based
on research-validated steady state VO2
prediction equations. Protocols
can be stored in a database, retrieved from the database, and printed. |

Proton Coefficients for Metabolites and Reactions of Non-Mitochondrial
Energy Metabolism
|
 |
Performs
the hundreds of calculations essential for the quantification of the
proton (H+) exchange for the 17 metabolites of non-mitochondrial
energy metabolism. From this
data, computations are also provided for H+ balance of the 21
reactions of non-mitochondrial energy metabolism.
All computations are performed in 0.01 pH unit increments across
the skeletal muscle cellular physiological pH range of 7.0 to 6.0.
Chemical structures are provided for all metabolites and H+
coefficient curves across the pH range are also illustrated.
All data can be saved as text files. |
