ECG/respiration monitor calibrator

Area of Science:

• Biomedical Engineering
• Medical Device Calibration
• Clinical Monitoring

Background:

• Electrocardiogram (ECG) and respiration monitors are critical for patient assessment.
• Regular calibration ensures the accuracy and reliability of these vital monitoring devices.
• Existing calibration methods can be time-consuming or expensive for biomedical staff.

Purpose of the Study:

• To describe the design and construction of a novel calibrator for ECG/Respiration monitors.
• To provide a quick, inexpensive, and accurate method for biomedical staff to verify monitor performance.
• To enable concurrent calibration of both ECG and respiration waveforms.

Main Methods:

• The paper details the construction of a calibrator by Biomedical Engineering staff.
• The calibrator is designed for a build time of one day and a parts cost under fifty dollars.
• The device connects to the patient cable of an ECG/Respiration monitor.

Main Results:

• The calibrator generates a calibrated ECG-pulse with specified rate and amplitude.
• Simultaneously, it produces a calibrated respiration waveform.
• The device offers a rapid and cost-effective solution for monitor calibration.

Conclusions:

• The developed calibrator provides an efficient and economical tool for biomedical departments.
• It facilitates accurate and concurrent verification of ECG and respiration monitor functions.
• This innovation supports the maintenance of high standards in patient monitoring equipment.
