Key Takeaways
- ResMed, Hamilton Medical and ZOLL Medical held the top three positions in the global ventilator market in 2025, according to iData Research.
- The global anesthesia, respiratory and sleep management device market was worth $14 billion in 2025 and is forecast to reach about $19.2 billion at a 4.7% CAGR.
- iData identifies AI-driven ventilation optimization and predictive analytics as the leading emerging technology in this market.
- Ventilators are a mature, high-volume segment, so growth is slower than in digital areas like anesthesia information management.
- The competitive field is reshuffling, with ZOLL absorbing former Vyaire product lines and Medtronic winding down its ventilator business.
Who are the top ventilator companies in 2026
The top three ventilator companies in 2026 are ResMed, Hamilton Medical and ZOLL Medical, ranked by 2025 global market share in iData Research’s ventilator market analysis.
ResMed holds the first position, Hamilton Medical the second and ZOLL Medical the third.
That ranking covers the full ventilator market as iData defines it, spanning acute care, sub-acute care, home care, neonatal, non-invasive and emergency transport devices.
ResMed is built around home and non-invasive ventilation. Hamilton Medical is built around the intensive care unit. ZOLL Medical spans acute, neonatal and portable care.
Why ResMed leads the ventilator market
ResMed leads because it dominates the part of respiratory care that has moved out of the hospital.
Its Astral 100 and Astral 150 devices deliver both invasive and non-invasive life support ventilation for patients weighing more than 5 kg, in the home, in hospital and during transport.
The Stellar series covers portable non-invasive ventilation for patients with progressive respiratory conditions.
What ties the portfolio together is AirView, ResMed’s cloud platform for remote monitoring of therapy data and device settings.
That connectivity is the foundation predictive respiratory care is being built on.
ResMed has also been buying and building in that direction. It acquired VirtuOx in May 2025, and in December 2025 it received FDA clearance for Smart Comfort, an AI-enabled feature that personalizes CPAP therapy.
ResMed also benefits from a competitor’s stumble. iData notes that Philips has faced product recalls in recent years, which helped ResMed extend its lead across the wider respiratory and sleep market.
What makes Hamilton Medical a top ventilator company
Hamilton Medical is the clearest example of automated ventilation already in daily clinical use.
Its Adaptive Support Ventilation mode adjusts respiratory rate, tidal volume and inspiratory time breath by breath, based on the patient’s lung mechanics and effort.
INTELLiVENT-ASV goes further. It is a closed-loop mode that automatically controls oxygen delivery, minute ventilation and PEEP using end-tidal CO2 and pulse oximetry readings.
The company’s IntelliSync+ technology analyzes waveform shapes at least one hundred times per second to detect patient effort and reduce patient-ventilator asynchrony.
In December 2025, Hamilton Medical announced a cooperation with Timpel to introduce PulmoMap, an electrical impedance tomography device that connects to the HAMILTON-C6 and shows real-time lung ventilation on a separate display.
The direction is consistent. Hamilton Medical wants the ventilator to see more and decide more on its own.
Why ZOLL Medical ranks among the top ventilator companies
ZOLL Medical earned its position largely through acquisition.
In October 2024, the Asahi Kasei company completed its purchase of select Vyaire Medical ventilator product lines out of Vyaire’s Chapter 11 proceedings.
That deal brought the Bellavista, Fabian, LTV, and 3100 HFOV lines into ZOLL’s respiratory portfolio.
The breadth is the point. Bellavista serves acute care, Fabian and 3100 HFOV serve neonatal ventilation, and LTV covers portable and non-acute use.
Few ventilator companies cover that many settings from one catalog.
The timing was also favorable. iData notes that Medtronic has publicly announced plans to wind down and exit its ventilator product line, while continuing service and support obligations for installed systems.
How AI is changing ventilation and respiratory care
iData Research identifies AI-driven ventilation optimization and predictive analytics as the leading emerging technology in the ventilator market.
Advanced systems now use machine learning to adjust ventilation parameters based on patient-specific breathing patterns and real-time physiological data.
The clinical goals are specific. Predict patient deterioration earlier, optimize weaning, and reduce the risk of ventilator-induced lung injury.
Published research supports the direction. A 2025 review in the National Library of Medicine describes AI continuously monitoring patient parameters, recommending or automatically adjusting ventilator settings, and flagging respiratory deterioration before a crisis.
A separate 2025 review of machine learning in ventilation management found promise in predicting successful extubation and dynamically adjusting ventilator parameters, while noting real challenges around data integration, model interpretability and real-time performance.
That caveat is worth holding onto. The technology is advancing faster than the validation behind it.
What is next for the ventilator market
Two shifts sit alongside AI in iData’s outlook.
The first is the expansion of non-invasive and home-based respiratory care. Portable ventilators, high-flow nasal cannula systems and compact oxygen concentrators are moving treatment out of hospitals, supported by better batteries and simpler interfaces.
The second is telemedicine and remote patient monitoring. Cloud-connected devices let clinicians track compliance and clinical parameters in real time, which matters most in sleep apnea and COPD management.
Growth expectations should stay realistic. iData classifies ventilators as a mature, high-volume segment where market saturation and long replacement cycles slow expansion, unlike faster-growing digital areas such as anesthesia information management systems.
The opportunity for ventilator companies is less about selling more units and more about selling smarter ones.
Frequently asked questions about ventilator companies
Who is the largest ventilator company in the world?
ResMed held the leading position in the global ventilator market in 2025, according to iData Research, followed by Hamilton Medical and ZOLL Medical.
Which ventilator companies use AI?
Hamilton Medical offers closed-loop automated modes including INTELLiVENT-ASV, and ResMed received FDA clearance in December 2025 for Smart Comfort, an AI-enabled therapy personalization feature. iData ranks these companies by market share, not by AI capability.
Is Medtronic still making ventilators?
iData Research reports that Medtronic has publicly announced plans to wind down and exit its ventilator product line, while continuing service, support, and certain consumables for installed systems.
What happened to Vyaire Medical ventilators?
ZOLL Medical completed its acquisition of select Vyaire Medical ventilator product lines in October 2024, including Bellavista, Fabian, LTV and 3100 HFOV.
How big is the respiratory device market?
iData Research valued the global anesthesia, respiratory and sleep management device market at $14 billion in 2025, forecast to reach approximately $19.2 billion at a CAGR of 4.7%.
What is predictive respiratory care?
Predictive respiratory care uses machine learning on ventilator and physiological data to anticipate events such as respiratory deterioration or weaning readiness, rather than reacting after they occur.
