Our passion. Intelligent Ventilation solutions

We want to help our fellow humans - with ventilation technologies that are safe, effective, and lung-protective. And we want to lessen the load for those who make extraordinary efforts every day, helping seriously ill patients fight their way back to health.

That is why we are committed to helping medical teams deliver the best respiratory care – to anyone, anywhere. Ever since we were founded in 1983, our focus has been on supporting the frontline heroes of critical care.

That commitment is present in everything we do.

Our management. A family matter

As the third generation of the Hamilton family to lead our company, Hamilton Medical means the world to Bob Hamilton, our CEO.

Working in tune with a team of seasoned professionals and leaders in the field of medical technology, Bob lends year’s worth of experience and knowledge to continue making our company a success, striving to achieve our goal of helping medical teams deliver the best respiratory care.


Our users. Every application counts

Medical teams around the world are accustomed to the toughest working conditions but have seldom been challenged to the extent that they are today.

Our research. Advancing ventilation technology

Since the very beginning, we have invested a great deal of time and money in research. There is room for new ideas, innovative approaches, and for clinical studies, all in close collaboration with ventilation experts from around the world.

In this team you can find a very high density of professionals with doctoral and post-doctoral degrees, not only in medicine and medical engineering, but also in mathematics and physics.

We make way for innovation, and the results speak for themselves. Over the last few decades, we have revolutionized mechanical ventilation. Not just once, but many times. And we will keep on doing so.

The development of the ventilators The development of the ventilators

We have set new industry standards. And will continue to do so

We first entered the market in 1984 with one of the first microprocessor-controlled ventilators and proximal flow measurement. At the end of the 80s, we built on this foundation by launching our digital oxygen mixer and a setting to control expiratory trigger sensitivity.

1991 saw a big leap forward in the way patient information was displayed graphically and by 1997 ,the time had come to unveil our ASV mode: a ventilation mode that automatically adjusts ventilation to changing lung mechanics. With the start of the new millennium, we introduced P/V Tool for recruitment maneuvers and the Ventilation Cockpit in 2008.

2010 brought another paradigm shift in mechanical ventilation as we introduced the world to INTELLiVENT-ASV: an intelligent ventilation mode that applies lung-protective ventilation automatically (Wendel Garcia PD, Hofmaenner DA, Brugger SD, et al. Closed-Loop Versus Conventional Mechanical Ventilation in COVID-19 ARDS. J Intensive Care Med. 2021;36(10):1184-1193. doi:10.1177/088506662110241391​). Innovation never stops, and since 2012 we have launched more groundbreaking ventilators such as our HAMILTON-MR1 ventilator with magnetic field scanners, and our HAMILTON-T1 Military transport ventilator with an NBC filter, night vision goggles option, and more.

As we continue to bring medtech into the 21st century, we have developed our devices to go hand in hand with our new technologies such as IntelliSync+: a technology that mimics an expert‘s eye by continuously analyzing waveform shapes at least hundred times per second. What’s next? Stay tuned.

Like numbers? Here a few facts for you

We started small and simply equipped in an unusual environment: a motel in Bonaduz in the canton of Grisons, Switzerland. The visions of our founder Steve Hamilton were all the greater:

"I wanted to create a fully automated ventilation system, which could be used everywhere and by everyone."

We achieved Steve's vision with INTELLiGENT-ASV. And now? Well, now we just keep taking the user experience to the next level. Again, and again.

We are a multinational team of more than 850 employees worldwide with different ages, world views, cultural backgrounds, identities, and nationalities. We are united by our mutual respect and a common goal: We are committed to helping medical teams deliver the best respiratory care - to anyone, anywhere.

Pretty impressive. We think so too. We currently have over 605 property rights in more than 30 countries. Innovative strength is part of our DNA, so these numbers are far from the end of the line.

Closed-Loop Versus Conventional Mechanical Ventilation in COVID-19 ARDS.

Wendel Garcia PD, Hofmaenner DA, Brugger SD, et al. Closed-Loop Versus Conventional Mechanical Ventilation in COVID-19 ARDS. J Intensive Care Med. 2021;36(10):1184-1193. doi:10.1177/08850666211024139


Lung-protective ventilation is key in bridging patients suffering from COVID-19 acute respiratory distress syndrome (ARDS) to recovery. However, resource and personnel limitations during pandemics complicate the implementation of lung-protective protocols. Automated ventilation modes may prove decisive in these settings enabling higher degrees of lung-protective ventilation than conventional modes.


Prospective study at a Swiss university hospital. Critically ill, mechanically ventilated COVID-19 ARDS patients were allocated, by study-blinded coordinating staff, to either closed-loop or conventional mechanical ventilation, based on mechanical ventilator availability. Primary outcome was the overall achieved percentage of lung-protective ventilation in closed-loop versus conventional mechanical ventilation, assessed minute-by-minute, during the initial 7 days and overall mechanical ventilation time. Lung-protective ventilation was defined as the combined target of tidal volume <8 ml per kg of ideal body weight, dynamic driving pressure <15 cmH2O, peak pressure <30 cmH2O, peripheral oxygen saturation ≥88% and dynamic mechanical power <17 J/min.


Forty COVID-19 ARDS patients, accounting for 1,048,630 minutes (728 days) of cumulative mechanical ventilation, allocated to either closed-loop (n = 23) or conventional ventilation (n = 17), presenting with a median paO2/ FiO2 ratio of 92 [72-147] mmHg and a static compliance of 18 [11-25] ml/cmH2O, were mechanically ventilated for 11 [4-25] days and had a 28-day mortality rate of 20%. During the initial 7 days of mechanical ventilation, patients in the closed-loop group were ventilated lung-protectively for 65% of the time versus 38% in the conventional group (Odds Ratio, 1.79; 95% CI, 1.76-1.82; P < 0.001) and for 45% versus 33% of overall mechanical ventilation time (Odds Ratio, 1.22; 95% CI, 1.21-1.23; P < 0.001).


Among critically ill, mechanically ventilated COVID-19 ARDS patients during an early highpoint of the pandemic, mechanical ventilation using a closed-loop mode was associated with a higher degree of lung-protective ventilation than was conventional mechanical ventilation.
