• Adult, pediatric, and neonatal ventilation

    The HAMILTON-G5 mechanical ventilator provides effective, safe, and lung-protective ventilation for adult, pediatric, and neonatal patients. For neonatal patients, a specifically developed neonatal proximal flow sensor is used. The tidal volume range goes down to as low as 2 ml.

    All features

    INTELLiVENT-ASV is an advanced ventilation mode based on the Adaptive Support Ventilation (ASV) mode and acts as your assistant at the bedside. With this mode, the clinician sets target ranges for PetCO2 and SpO2, as well as limits for various controls. INTELLiVENT-ASV then adjust the controls for CO2 elimination (%MinVol) and oxygenation (PEEP and Oxygen), and keeps the patient within the predefined ranges with minimal clinician interaction.

    INTELLiVENT-ASV continuously monitors specific physiologic parameters and adjusts the settings as appropriate, while always applying individualized lung-protective strategies.

    When enabled, INTELLiVENT-ASV can also help promote early weaning with Quick Wean. 

    Clinical studies show that INTELLiVENT-ASV:

    • Requires fewer manual adjustments than conventional ventilation, consequently reducing the workload for the healthcare team (1, 2, 3)
    • Is rated as having the most technological capabilities of all evaluated modes in terms of safety, comfort, and weaning (4)
    • Follows the latest recommendations for lung-protective ventilation in terms of tidal volumes and driving pressure (5, 6)

  • P/V Tool® Pro - the protective ventilation tool

    The Protective Ventilation Tool (P/V Tool Pro) performs a respiratory mechanics maneuver that records a quasi-static pressure/volume curve. This method can be used to assess lung recruitability and determine the recruitment strategy to apply.

    The P/V Tool Pro can also be used to perform a sustained inflation recruitment maneuver and measure the increase in lung volume. It is particularly helpful for ARDS patients, as selecting an appropriate lung recruitment strategy and the correct PEEP setting as an anti-derecruiting force are critical for this patient group.

    In combination with esophageal pressure measurement, the P/V Tool Pro can give you a clearer understanding of the lung and chest-wall mechanics. This enables you to apply a lung-protective ventilation strategy by titrating the PEEP level (Talmor 2008), and optimizing the parameters for the recruitment maneuver, driving pressure and tidal volume.

    All features
  • IntelliSync+

    IntelliSync+ keeps an eye on patient-ventilator synchrony by continuously analyzing waveform shapes hundreds of times per second. This allows IntelliSync+ to detect patient efforts and cycling immediately, and initiate inspiration and expiration in real-time. IntelliSync+ applies to invasive and noninvasive ventilation, regardless of the ventilation mode.

    All features
  • Transpulmonary pressure measurement

    Esophageal pressure is considered  a substitute for pleural pressure. Partitioning of lung and chest wall compliance is then possible and is very useful to set PEEP and tidal volume, assess lung recruitability, and perform recruitment maneuvers. Transpulmonary pressure is airway pressure minus esophageal pressure measured during an end-inspiratory or end-expiratory occlusion, and represents the pressure to distend the lung parenchyma. 

    Transpulmonary pressure allows customization of ventilator settings to optimize lung recruitment and protective ventilation in mechanically ventilated patients.

  • Noninvasive ventilation (NIV)

    The noninvasive ventilation modes deliver pressure-supported, flow-cycled spontaneous breaths (NIV and NIV-ST mode) and pressure-controlled, time-cycled mandatory breaths (NIV-ST mode). In NIV modes, the ventilator functions as a demand flow system. When pressure support in NIV mode is set to zero, the ventilator functions like a conventional CPAP system.

    The leak compensation function adapts to changing breath patterns and airway leaks to achieve optimum synchronization between patient and device. 

    All features
  • High flow oxygen therapy

    The HAMILTON-G5 optionally provides an integrated high flow oxygen therapy* mode. With this enhancement, the HAMILTON-G5 gives you a variety of therapy options in one device, including invasive and noninvasive ventilation, and high flow oxygen therapy. In just a few steps, you can change the interface and use the same device and breathing circuit to accommodate your patient’s needs.

    *Always use active humidification during high flow oxygen therapy.

    All features

    The integrated pneumatic nebulizer is fully synchronized with the inspiration and exhalation timing. The delivery of a fine mist of drug aerosol particles helps you improve your ventilation efficiency, for example in cases of bronchospasm or chronic hypercapnia.

    All features
  • Adaptive Support Ventilation (ASV)

    All Hamilton Medical ventilators feature the intelligent ventilation mode, Adaptive Support Ventilation® (ASV®). ASV continuously adjusts respiratory rate, tidal volume, and inspiratory pressure depending on the patient’s lung mechanics and effort. ASV adapts ventilation breath-by-breath, 24 hours a day, from intubation to extubation.

    A lung-protective strategy ensures ASV’s safety. ASV attempts to guide the patient using a favorable breathing pattern. ASV has been a well established mode in critical care since 1998 and has become a standard ventilation mode in many units around the world.

    Clinical studies show that ASV:

    • Shortens the duration of weaning without increasing the number of interventions by the clinician (1, 2, 3, 4 ,5)
    • Shortens the duration of mechanical ventilation in various patient populations with fewer manual settings (3, 5, 6)

  • All ventilation modes

    The ventilator supports the following types of modes:

    • Intelligent ventilation modes with Adaptive Support Ventilation (ASV) and INTELLiVENT-ASV
    • Pressure-controlled modes (including biphasic modes)
    • Adaptive volume-controlled modes
    • Conventional volume-controlled modes
    • Pressure and volume support modes
    • Modes for noninvasive ventilation
    • High flow oxygen therapy

    Thanks to its biphasic pneumatic design, the ventilator always yields to spontaneous breathing in all modes. This is achieved through a special valve control system independent of any trigger mechanism.

    All features
  • nCPAP modes

    The nCPAP modes are designed so that you only need to set the desired CPAP pressure. The flow is subsequently adjusted based on patient conditions and potential leaks. This prevents unintended peak pressures, guarantees highly efficient leak compensation, and helps to reduce oxygen consumption. Flow adjustment occurs very rapidly due to high sensitivity of the pressure measurement.

    All features
  • Driving pressure

    The HAMILTON-G5 offers continuous monitoring and display of driving pressure.

    All features
  • Heliox therapy

    Heliox therapy is gaining acceptance for cases of acute and life-threatening upper airway obstruction. With the Heliox option, HAMILTON-G5 mechanical ventilator  helps you successfully reduce the patient’s work of breathing while treating the cause of the obstruction.

    All features
  • Leak compensation for NIV and invasive ventilation

    The leak compensation function automatically adjusts the inspiratory and expiratory trigger sensitivity to airway leaks, and ensures optimal synchronization with the patient’s breathing pattern. This is achieved in both invasively and noninvasively ventilated patients.

    All features
  • Flexible device configuration

    To adapt the ventilator to your user environment, you can configure the device in several ways:

    • Mounted on a trolley, with the interaction panel on top or in front
    • As a shelf-mounted version with the interaction panel on the unit’s side or on the shelf
    All features
  • Optimal alarm detection

    Even from a distance or at high noise levels, the HAMILTON-G5 mechanical ventilator alarming is easily identified by the top-mounted 360°-visible alarm lamp. The optional nurse call capability provides additional support for optimal alarm detection.

    All features
  • Hot-swappable battery backup

    A battery operating time of more than 7 hours is provided by one integrated and one hot-swappable battery. The battery operating time can be prolonged indefinitely with the use of additional hot-swappable batteries.

    All features
  • Serial interface for connection to PDMS or patient monitors

    The serial RS-232 interface provides ports for connection to hospital monitors or Patient Data Management Systems (PDMS).

    All features
  • Dynamic Lung for simplified patient monitoring

    The Dynamic Lung panel is part of the Ventilation Cockpit. It displays tidal volume, lung compliance, interaction with the heart, patient triggering, and resistance in real-time. The lungs expand and contract in synchrony with actual breaths. The shape of the lungs changes with compliance. Numeric values for resistance (Rinsp) and compliance (Cstat) are also displayed.

    All features
  • Vent Status for weaning assessment

    The Vent Status panel is part of the Ventilation Cockpit. It displays six parameters related to the patient’s ventilator dependence, including oxygenation, CO2 elimination, and patient activity. A floating indicator (floater) that moves up and down within the column shows the value for a given parameter. The panel is updated breath by breath. When all values are in the weaning zone, the Vent Status panel is framed in green, indicating that spontaneous breathing trials should be considered. 

    All features
  • Configurable loops and trends

    The ventilator can display a dynamic loop based on two selectable monitored parameters. With the trend function, the ventilator can display monitored parameters in a selectable time frame. The device continually stores the monitored parameters in memory, so you have access to any of this data, even in standby. 

    All features
  • Tube Resistance Compensation (TRC)

    To reduce the patient’s work of breathing, the ventilator’s tube resistance compensation (TRC) feature offsets the flow resistance imposed by the tracheal (ET) or tracheostomy tube. 

    All features
  • Proximal flow sensor for precise measurements

    The proximal flow sensor precisely measures the pressure, volume, and flow directly at the patient’s airway opening. This provides the required sensitivity and response time, and prevents dead space ventilation. Your patient is better synchronized and has less work of breathing as a result.
