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.
