North America Capnography Devices Market: By Product Type (Capnographs, disposables), By Technology (Hand-Held Monitors, Stand-Alone Monitors, Others), By Application (Anesthesia, Procedural Sedation, Intensive Care, Pain Management, Emergency Medicine, Others), By End-User (Hospitals, Clinics, and Ambulatory Surgical Centres) and Country Forecast 2020-2031

North America Capnography Devices Market size was valued at US$ X million in 2024 and is expected to reach US$ X million by 2031, growing at a significant CAGR of X% from 2025-2031. Capnography is the process of monitoring partial pressure or concentration of carbon dioxide in respiratory gases by using capnogram. It is majorly used as a monitoring tool during intensive care and anesthesia. Capnography helps to anesthesiologists to prevent the hypoxia and help to determine the situations that can lead to hypoxia and may cause irreversible brain damage. Due to these advantages, capnography is widely used in endoscopic suites, emergency rooms, x-ray rooms, and on-site emergency and trauma centers. In healthy individuals, difference between the arterial blood and expired CO₂ partial pressure is very small however, in presence of lung disease, and some congenital heart disease the difference is increased and can exceed 1 kPa. However, alternative devices availability for capnography such as pulse oximeter, new clinical studies restraining the usage in non-intubated individuals, and issues associated with capnography usage are expected to impede the growth of capnography devices market.
