Study Notes
Technology in Healthcare Delivery
- Technology enhances treatment effectiveness by improving therapeutic interventions.
- Four levels of technological intervention in healthcare:
- Level 2: Proposes diagnoses based on parameters collected during diagnosis and related patient information.
- Level 3: Integrates and interprets all patient data using expert systems to deliver tailored therapies.
Medical Instrumentation Approach
- The approach includes:
- Identification of pathology through observable changes in organ function or anatomy.
- Measurement of variables in a different domain (e.g., voltage, pressure).
- Representation of variables to assist clinicians in diagnosing pathology and its extent, while managing potential noise and artifacts.
Biomedical Instrument Design
- Design influenced by clinical requirements, ensuring accuracy in detecting changes related to pathologies.
- Specifications must be established heuristically if state-of-the-art devices are lacking.
- Uncertainties must be controlled as they propagate through the medical system.
Extraction of Physiological Parameters
- Pathologies lead to functional or anatomical changes necessitating diagnosis.
- Changes can be:
- Directly observed (e.g., using imaging devices like X-rays).
- Indirectly estimated (e.g., through pulmonary function analyzers).
- Main objective of medical instruments is to quantify these modifications.
Identifying Pathology Parameters
- Pathologies are associated with specific measurable parameters:
- Relevant points in waveforms (e.g., ECG amplitudes, time intervals).
- Ensemble parameters derived from statistical analysis (e.g., quantitative EEG analysis).
- Simplified functions (e.g., quantifying apnea through bispectral index).
Medical Instruments Requirements and Standards
- Continuous monitoring of critical requirements is essential:
- Signal performance (e.g., frequency response).
- Electrical safety (e.g., leakage current, harmful energies).
- Electromagnetic compatibility (EMC).
- Mean time between failures (MTBF).
- Production costs.
Importance of Standards in Design
- Standards provide benefits such as:
- Enhancing customer appeal and marketability.
- Ensuring product quality and reliability.
- Creating competitive advantages.
- Reducing industrial research costs and risks.
