Monitoring Patients During Ventilation with Hamilton T1

Introduction

  • The module provides instructions on monitoring patient data using the Hamilton T1 ventilator.
  • It covers numerical and graphical parameters and customizing display information.
  • Completion time for the module is less than 10 minutes.

Display Overview

  • Primary focus on patient monitoring.
  • Center Display:
    • Two primary graphic areas:
      • Pressure-Time Waveform: Always displayed.
      • Customizable area for additional data (waveforms, loops, trends, intelligent graphic panels).
  • Left Display:
    • Numerical patient data (Main Monitoring Parameters - MMPs).
    • Displays ventilation mode, patient group, and gender.
  • Monitoring Window: Access additional data, including CO2 and SpO2 values.

Numerical Monitoring Parameters

  • Four main monitoring parameters:
    • Peak pressure
    • Expiratory minute volume
    • Tidal volume
    • Total respiratory rate
  • Customizable display and ordering of parameters.
  • Alarm Indication:
    • Parameters change color based on alarm priority (yellow for medium, red for high).

Graphic Monitoring

  • Pressure-Time Waveform:
    • Plots pressure against time.
    • Red line: High-pressure alarm limit.
    • Blue line: Maximum safe pressure (10 cm below high-pressure limit).
    • Options to change time scale, freeze, and scroll graphics.

Additional Graphic Options

  • Waveforms, Loops, Trends, Intelligent Graphic Panels:
    • Display additional waveforms by selecting through tabs.
    • Loops: Display variable relationships (e.g., Pressure-Volume loop).
      • Shows current values for resistance, compliance, and time constant.
      • Save loops with timestamp.

Intelligent Graphic Panels

  • Dynamic Lung Panel:

    • Shows tidal volume, respiratory system compliance, airway resistance, and patient triggering.
    • Displays data in a combined moving lung graphic.
  • Vent Status Panel:

    • Shows patient's dependency on the ventilator across six parameters.
    • Floating indicators move with parameter changes.
  • ASV Graph (Adaptive Support Ventilation):

    • Displays current minute ventilation target, tidal volume, and frequency.
    • Includes red safety frame for target limits.

Data Storage and Trends

  • All monitored parameters stored from the time ventilator is switched on.
  • Trend Graphs:
    • Analyze data over time.
    • Use Freeze and Cursor Measurement function for specific data points.

Monitoring and Accessing Parameters

  • Access all monitoring parameters through the Monitoring window.
  • Different windows (2 and 3) show varied parameter sets.
  • Resistance, Compliance, Auto-PEEP Measurement:
    • Uses Least Squares Fitting (LSF) method.
    • Suitable for all modes without interrupting ventilation.

Conclusion

  • Knowledge of available monitored patient parameters and access methods on the ventilator.
