Pulse Oximetry Project

Summary of Information Flows, Workflow, Functional and Data Requirements


Overview
Overview

  • Project focus on device-to-information system exchanges

    • A device manager may be used to support the standard-based exchange

  • Standardization of information exchange

    • Between device and information system

    • Between device manager and information system

  • Information flow

  • Workflow

    • Identifies configuration, verification, etc.


Information flow
Information Flow

Measured results, abnormal flags, error information


Validatio n at the point of care
Validation at the point of care

Verification

Standard-based Transactions


Monitoring and validation
Monitoring and validation

Standard-based Transactions

Verification


Workflow
Workflow

Device may monitor continuously or episodic/spot check

If measurement fails to acquire a value, an alarm may be sent

Verification at the point of care




Data analysis for transactions
Data Analysis for Transactions

Standard Codes will be used to represent these concepts

Current Standard and future technical enhancements created by this project

Associated information

Measured Results


Results information detail
Results Information - Detail

Oxygen Saturation identifier is a code as “Coded Value”

Zero or one occurrences - Optional

Result: numeric quantity and units

Zero or more occurrences – Repeated, optional

Indicates the result is out of range

Must match the probe

Standard codes, units of measure



Verification of results

These data structures are reused for all identifiers, names, etc.


Questions
Questions

  • Delayed Results

    • If a device fails to obtain a result, should it resend the previous value to the information system?

  • Missing Results

    • If a device fails to obtain a result (e.g. probe disconnected, low signal), should it send any values (e.g. default “0”) or stop sending information?

  • Frequency of reporting pulse oximetry

    • Continuous (e.g. OR, ICU) : one minute intervals

    • Spot-check: on-demand
