New: INTELLiVENT-ASV Movie:
10 years ago ASV® was the first step in closed loop ventilation, now INTELLiVENT®-ASV is the new era of mechanical ventilation!
More than ten years ago Adaptive Support Ventilation (ASV®) was a major breaktrough in closed loop ventilation. Over the last decade a long list of scientific studies about ASV® has been published. These studies show the potential and the benefits of a closed loop ventilation solution based on the algorithms of ASV®. With ASV® the breathing pattern during mechanical ventilation continously adapted to actual lung mechanics of the patient, based on physiological algorithms.
With INTELLiVENT®-ASV mechanical ventilation enters a new era. For the first time, ventilation and oxygentation will be automatically adapted to the patient's need. The proven physiological model of ASV® is one of the cornerstones of INTELLiVENT®-ASV. All studies showing the benefits of ASV underly the solid fundament of INTELLiVENT®-ASV.
The Right Picture Is Worth a Thousand Numbers
Graphical user interfaces are part of our daily consumer experience. It doesn't matter in which situation, driving a car, using a cell phone or working with a medical device the graphical user interface is our direct access to the relevant information in this situation. Especially in complex environments, handling and interpretation of information and data can become a dominant factor to quickly make the right decisions.
HAMILTON MEDICAL has always been first in line to improve graphical user interfaces. With concepts like the ASV graph, the dynamic lung or the vent status panel, important progress has been achieved to guarantee the highest level of ease of use.
The graphical user interface plays a crucial role in HAMILTON MEDICAL's fully closed loop ventilation solution INTELLiVENT®-ASV. Closed loop systems take into account the physiological situation of the patient and are continuously adapting the settings of the ventilator. Based on the patient’s lung mechanics, his CO2 production, patient's saturation and the actual hemodynamic status of the patient, the following automatic adaptations are made according to patient’s needs and also changes in his needs.
1.) The graphical user interface informs the clinician intuitively about the actual physiological situation of the patient.
2.) It makes the ventilator actions and automatic adjustments transparent to the clinicians, also explaining the rational of the action.
3.) The status of the ventilator is always very intuitively distinguishable, either the adjustment(s) are made automatically or the user is required to make them manually.
Independent of the situation if the device is working fully automatically or the user has chosen to operate the ventilator in a conventional, manual way, the user interface allows a new and intuitive access to basic physiological parameters and the resulting clinical decisions.
Scientific study about the Ventilation Cockpit: In a study concerning "information presentation" with respect to mechanical ventilation in the ICU, two methods of communicating patient variables to the clinicians have been analysed by a study conducted by Robert Albert, Noah Syroid, James Agutter and Dwayne Westenskow.
The first method could be described as the "traditional method" i.e. pressure and volume waveforms. The second as an integrated graphical data presentation i.e. the dynamic lung. The result of the study was, that HAMILTON MEDICAL's unique dynamic lung significantly improved the detection of variables in terms of time and accuracy and reduced the workload.

Less alarms and fewer manipulations of ventilator settings with ASV!
In this randomized control trial on cardiac surgery patients the weaning process between ASV and conventional synchronized intermittent ventilation followed by pressure support has been compared.
The investigators came to the following results: "ASV patients required fewer ventilatory settings manipulations (2.4 +/- 0.7 versus 4.0 +/- 0.8 manipulations per patient; P < 0.05) and endured less high-inspiratory pressure alarms (0.7 +/- 2.4 versus 2.9 +/- 3.0; P < 0.05)".
In addition they found that there was "less peak inspiratory pressure during the initial phase in ASV (17.5 +/- 0.8 versus 22.2 +/- 0.8 cm H(2)O; P < 0.01)".
The final conclusion: "The two approaches were equal in terms of outcome. In ASV, we observed fewer ventilator settings manipulations and a smaller amount of alarms, suggesting that this automatic mode may simplify postoperative respiratory management without delaying extubation.
