Global Respiratory Gas Monitoring Market Size & Trends Report Segmented by Product (Portable, Tabletop, Stationary), Technology (Infrared, Electrochemical, Mass, Photoacoustic), Application (Anaesthesia, Critical-Care, Chronic Respiratory Disease), End User (Hospitals/Clinics, ASCs) Forecast to 2031

Respiratory Gas Monitoring involves the continuous or intermittent measurement and analysis of the various gases associated with a patient's breathing to monitor their respiratory system and assure clinical safety. This includes monitoring oxygen (O2), carbon dioxide (CO2), nitrous oxide (N2O), and anesthetic gases during anesthesia, as well as in critical care, emergency medicine, and respiratory therapy. These types of monitoring equipment allow clinicians to assess ventilation, oxygenation, and metabolism instantly, which aids in identifying when a patient is having respiratory complications at an early stage. The use of respiratory gas monitors is prevalent in operating rooms, intensive care units (ICUs), and more frequently in home and outpatient settings for diagnosis and treatment of patients and improving patient outcomes.

Rising prevalence of respiratory diseases to propel market demand

The respiratory gas monitoring market is expanding due to the steady increase of respiratory diseases globally, healthcare systems are now focusing more on early diagnosis, prolonged monitoring, and proper treatment of these diseases. According to WHO, COPD is the fourth leading cause of death worldwide, causing 3.5 million deaths in 2021, approximately 5% of all global deaths; while Asthma affected an estimated 262 million people in 2019 and caused 455,000 deaths. Many individuals around the world will need ongoing monitoring and assessment of their lungs due to chronic lung diseases caused by pollution, smoking, occupational exposure to pollutants, aging, and various lifestyle changes. Furthermore, the long-term respiratory complications observed in post-COVID-19 patients have further expanded the pool of individuals requiring ongoing respiratory assessment and monitoring.

As the volume of patients with respiratory diseases continues to increase, clinicians need accurate, real-time tools to evaluate how well their patients' lungs are ventilating and how much gas is being exchanged, as well as the extent of the progression of their patients' diseases. Respiratory gas monitoring devices are a critically important part of measuring the parameters necessary to determine whether there are early signs of an increase in the severity of respiratory disease like, end-tidal carbon dioxide, oxygen concentration, and respiratory rate. These measurements also assist with determining whether any modifications in a patient's ongoing therapy are required and ultimately allow for the prevention of acute exacerbations of these diseases, particularly in high-risk patients with chronic pulmonary disease. The increasing number of people admitted to hospitals with respiratory illness is also increasing the demand for respiratory gas monitoring in critical care units, emergency departments, and operating rooms. Patients who experience severe asthma attacks, COPD exacerbations, pneumonia or ARDS often need close observation to ensure that their ventilatory and oxygenation needs are met. Therefore, hospitals are investing in advanced integrated respiratory monitoring systems to improve the safety of patients and their outcomes clinically.

The rise in the number of patients with respiratory disease is also driving the use of respiratory gas monitoring in home health care and long-term care. More chronic respiratory patients require continuous or periodic monitoring outside the hospital; otherwise, the potential exists for increased hospital readmissions and a lack of appropriate management of their disease's progression. Portable and/or wearable respiratory gas monitors enable remote monitoring of patients and provide support to home care models and other models of care that reflect the larger trends occurring within the health care system, such as reducing costs and providing patient-centered care.

Public health initiatives emphasizing early detection and prevention of respiratory diseases will continue to increase dependence on monitoring technologies that provide reliable monitoring. Respiratory disease continues to be a significant clinical and economic burden globally; therefore, a continued demand for accurate, connected, and scalable respiratory gas monitoring will occur, resulting in the disease prevalence being a driving force.

Greater focus on patient safety is driving the market growth

The increasing focus on patient safety is a primary driver of the respiratory gas monitoring industry, as healthcare providers continue to look for ways to reduce preventable complications and enhance clinical outcomes across all care settings. The focus on patient safety from global initiatives has increasingly been focused on continuous physiological monitoring to identify early signs like deterioration of patients, particularly in environments identified as high-risk as operating room, ICU, emergency department, and post-anesthesia care unit. Respiratory compromise is one of the most common causes of adverse events during anesthesia and critical care, which makes accurate gas monitoring essential for providing safe care to patients.

Clinical staff can use respiratory gas monitors to provide real-time information on the amount of oxygen, carbon dioxide, and anesthetic gases a patient is breathing, and assess a patient’s ventilation and oxygenation continuously. For example, end-tidal carbon dioxide (EtCO₂) is an important metric that provides timely indication of a patient’s respiratory status and can identify hypoventilation, airway obstruction, or equipment failure before they result in significant injuries to the patient. Hospitals that are focused on minimizing the incidence of hypoxia, respiratory depression, and anesthesia-related complications have adopted advanced respiratory gas monitoring technologies as part of their patient safety protocols.

Patient safety standards are being strengthened by regulatory agencies, accreditation organizations, and professional societies that play a key role. Guidelines increasingly recommend or mandate the use of capnography and gas monitoring during anesthesia, procedural sedation, and mechanical ventilation, creating an expanding market for these types of monitoring solutions. Patient safety is not just focused on acute care settings, but it also applies to long-term care and home care. For patients with chronic respiratory diseases or patients receiving opioid therapy, continuous or remote monitoring of respiratory gases can help detect early signs of respiratory depression, which reduces the risk for adverse events after discharge from the hospital. This encouraged the development of user-friendly and portable connected monitoring devices, which increase the ability to provide safe care across the entire continuum of care.

In addition to improving patient safety with implementation of the passion in patient safety, digital health technologies are providing further advancements in the role of respiratory gas monitoring for patient safety initiatives. Integration of respiratory gas monitoring with electronic health records, alarm management systems, and clinical decision support systems enhances the situational awareness and ability to intervene early. As healthcare systems globally prioritize zero-harm goals and value-based care models, the heightened focus on patient safety is expected to continue driving sustained adoption and innovation in the respiratory gas monitoring market.

Growth strategies adopted by players to establish their foothold in the market

Players operating in this market are adopting various growth strategies such as new product approval and launch, acquisitions, and partnerships and collaborations to garner market share. For instance,

• In May 2025, Medtronic received FDA Safer Technologies Program (STeP) designation for its investigational Nellcor pulse oximetry technology, supporting expedited development and regulatory review. The designation recognizes the technology’s potential to improve patient safety by enhancing oxygen saturation accuracy and reducing the risk of unrecognized hypoxemia across diverse patient populations
