Pulse oximetry project

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


Pulse oximetry project

Re-attach probe


Pulse oximetry project

Verification in the info system


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


Pulse oximetry project

Standard Codes will be used to represent these concepts


Pulse oximetry project

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
