Objective: To develop acid-base balance computer software for estimating acid-base disturbance rapidly and accurately.
Methods: The data module was set up, based on Henderson-Hasselbalch (H-H) and compensation formula, and the program was written with Delphi 5.0.
Results: The right RESULTS was 100.0 percent in 118 cases of acid-base disturbance patients by the software, while those with the right RESULTS was 89.8 percent by hands (P<0.05). In 20 cases pure acid-base disturbance, 70 cases double acid-base disturbance and 28 cases with triple acid-base disturbance, it took only (9.0+/-0.6) seconds, (8.9+/-1.3) seconds and (9.1+/-1.6)seconds respectively, with software, while which were much less than those by hands ((20.4+/-16.8) seconds, (92.4+/-45.3) seconds and (128.6+/-66.4) seconds, respectively, P<0.001).
Conclusion: This software has a terse interface, by which the acid-base disturbance was concluded exactly and quickly.
