Medical Analyzer Software

Introduction

Variability is the sign of life; therefore higher variability in physiological parameters is generally an indicator of better health. The use of variability for the diagnosis of several diseases is age old. Because of great potential of this technique, heart rate variability monitoring is a routine feature in the patient monitoring systems available in the market for employment in intensive care units and intensive cardiac care units. Bhabha Atomic Research Centre has integrated cardiac output, stroke volume/peripheral blood flow variability; with heart rate variability for the study of these changes in variety of diseases in a PC based Software developed called Medical Analyser. It has unique feature that it yields heart rate variability, cardiac output variability, stroke volume variability / peripheral blood flow variability from a single data acquisition session from the patient when used with Impedance Cardiovasograph hardware. The data acquisition is controlled by the PC, serially connected to the acquisition unit. The variability analysis and transfer to database is performed by the PC with the help of user-friendly software.

Functions

Medical Analyzer Software
This package consists of different screens providing many useful functions like

Data Acquisition with hardware of Impedance Cardiovasograph / Oxygen Saturation Monitor

Display of Acquired data in Time and Frequency Domain

Deriving Different Variabilities from the Acquired data

Saving of calculated parameters in Database for further reporting and analysis

Salient Features

Totally user friendly
Easy & faster data entry and retrieval from Access Database
Easy adaptability by clinicians/ medical practitioners
Comparison facility of the data from the same disease group and with the normal group
Analysis of the data in the validation phase, user defined reports/queries for comparison of variability in different disease group.
Pictorial representation in the form of graph for comparing changes (increase/decrease) in the parameters (peak amplitude/area) for all variability and for all disease can be obtained to view the whole data at a glance.
Queries are being used for finding out number of patients, average, standard deviation of a particular disease group.
Till the frequency ranges are established for LF1, LF2, MF1, MF2, HF1 and HF2, flexibility to set the frequency ranges so that peak can be shifted automatically.
Future expandability to accommodate new fields, variables, reports or queries.
Future support for employing fuzzy logic or neural network approach to incorporate automatic machine generated report on the patient.

Infrastructure Required

One electronic hardware engineer and one software engineer having professional knowledge of embedded system programming.
Impedance Cardiovasograph, Oxygen Saturation Monitor System.
Testing and programming facilities with electronic assembly shop are preferred.
