The global capnography devices market size was valued at USD 676.6 million in 2023 and is projected to grow at a CAGR of 10.0% from 2024 to 2030.

Expected advancements in technology, the increasing occurrence of respiratory conditions, and backing from government programs will enhance market expansion throughout the projected period. Attributed to its superior reliability and effectiveness, the rising use of capnography for managing respiratory illnesses is forecasted to enhance the clinical performance of these devices in monitoring patients. For instance, in 2022, 4.6% of adults were reported to have received a diagnosis of COPD, emphysema, or chronic bronchitis at some point. Office-based physician visits where COPD was noted in the medical records accounted for 4.2%. There were approximately 791,000 emergency department visits where COPD was the main reason for the visit.

Technological advancements in capnography, including the development of portable and handheld devices, improved accuracy, and seamless integration with other monitoring systems, significantly drive market growth by enhancing usability and expanding application areas. For instance, in June 2022, clinicians could further personalize care with Medtronic’s integration of INVOS regional oximetry (rSO2) and Microstream capnography (CO2) technologies. These continuous monitoring solutions became available on the GE Healthcare CARESCAPE precision monitoring platform, enhancing perioperative and ICU care.

Capnography Devices Market Segments:

Component Insights

The other component segment dominated the market and accounted for a share of 57.2% in 2023. Other components of capnography devices include sampling lines, sensors, airway adapters, anesthetic breathing circuits, cuvettes, cannulas, Luer connectors, etc. The sampling line is one of the major components, as the accuracy of end-tidal CO2 measurement and the quality of waveforms are highly dependent on it. For instance, in April 2021, Masimo announced FDA 510(k) clearance for Radius PCG, a portable, real-time capnograph with wireless Bluetooth. This device connects to the Connectivity Platform and Root Patient Monitoring and offers accurate, calibration-free end-tidal CO2 and respiration rate measurements within 15 seconds.

Technology Insights

The side stream segment accounted for the largest market revenue share of 53.2% in 2023. The significant growth is attributed to the extensive use of side-stream technology in anesthesia monitoring. Devices equipped with side-stream technology provide several advantages, such as easy connectivity and reduced sterilization challenges. For instance, EtCO2 monitoring is an effective way to detect serious health conditions such as hyper or hypothermia, requiring highly accurate and durable sensors. Philips Respironics' LoFlo sidestream sensor, which uses advanced infrared absorption spectroscopy, ensures precise respiration rate and EtCO2 measurements, producing clear programs even at respiratory rates as high as 150 breaths per minute.

Application Insights

The emergency medicine segment accounted for the largest market revenue share of 24.0% in 2023. Emergency medicine, encompassing acute care for obstetric, medical, and surgical emergencies, is driving significant growth in the emergency medical services segment. Capnographs are increasingly used to optimize prehospital ventilation, manage pediatric emergencies, and assess pulmonary blood flow. The rising incidence of trauma cases requiring rapid medical intervention further boosts the demand for these services. According to the American Association for the Surgery of Trauma, trauma is a leading cause of death for individuals under 45. It ranks as the fourth most common cause of mortality across all age groups.

Type Insights

The hand-held segment accounted for the largest market revenue share of 60.6% in 2023. Hand-held capnography devices, crucial for monitoring CO2 levels and ensuring patient safety, are increasingly adopted due to their portability and versatility, making them ideal for diverse medical settings such as hospitals, clinics, and ambulances. Their ease of use enhances their appeal across various healthcare environments, supporting critical care in anesthesia, sedation, and emergency scenarios.

End Use Insights

The hospitals segment accounted for the largest market revenue share of 57.7% in 2023. They are owing to their higher capability of patient monitoring, availability of a higher number of ventilation measurement systems, and higher adoption. The market is likely to grow due to the rising number of surgeries and growing prevalence of lifestyle disorders, such as diabetes, respiratory diseases such as asthma, and others. Furthermore, the presence of state-of-the-art infrastructure in hospitals in developed countries is expected to drive growth in the segment. According to the American Hospital Association findings, in 2023, nearly 6,129 hospitals were registered in the U.S. with nearly 919,649 staffed beds.

Regional Insights

North America capnography devices market dominated the market in 2023. The rising prevalence of respiratory diseases as a consequence of unhealthy lifestyles and high stress levels is the high impact rendering driver for the regional market. In addition, the incorporation of new reimbursement models for respiratory and monitoring solution procedures in this region and the stringent regulatory guidelines aimed at patient safety, medical efficacy, and clinical efficiency are expected to drive product demand in the future. The American Psychological Association's 2020 survey found that increased stress negatively impacted 49% of U.S. adults' behavior, leading to heightened bodily tension in 21%.
