GE Healthcare modular monitoring solutions provide, on a single monitor screen, the full picture of your patient’s hemodynamic, ventilation and gas exchange status. We offer multiple technologies and clinical parameters to help meet your care area and patient specific needs in respiratory monitoring. A full range of options from standard CO2 monitoring to advanced Patient Spirometry and direct gas exchange monitoring help clinicians to detect changes in patient’s respiration and ventilatory status to support treatment decisions. 

Compact Airway Modules: Comprehensive respiratory monitoring for anesthesia and critical care applications

Benefits and Technology


GE Healthcare respiratory monitoring information is available with other vital signs data on a single screen offering clinicians a single source of clinical information at the point-of-decision.   

ETCO2 monitoring may help clinicians maintain normoventilation, adjust ventilation and detect changes in patient ventilatory status (e.g., increased/decreased AaCO2 difference, pulmonary embolism).   

Patient Spirometry monitoring may help clinicians detect changes in patient ventilatory status (e.g., lung injury, bronchospasm, dynamic hyperinflation), support treatment decisions such as weaning prediction and detect Barotrauma, volotrauma, pneumothorax, atelectasis and malfunctions in breathing circuit and airway functionality.   

Gas Exchange monitoring may help clinicians detect changes in patient metabolic status caused by injuries or septic reactions, assess nutritional needs, support treatment decisions such as oxygen delivery, ventilator settings and wean patients from ventilators.   


The needs of neonatal to adult ETCO2 monitoring are covered with mainstream and sidestream based technology solutions.


CO2 monitoring is widely regarded as an essential parameter to measure efficacy of patient ventilation. It provides a wealth of valuable diagnostic information on patient respiratory status and guidance in diagnostics and ventilation management. There are, in addition to critical and perioperative care areas, several other facilities monitoring CO2 such as emergency, procedural units, endoscopy, cath labs and outpatient surgery centers. To help meet the different care area and patient specific needs, GE Healthcare offers this essential respiratory parameter available in several products and with options of sidestream or mainstream measurement technologies.

Respiratory Gases

GE Healthcare has a versatile offering of airway gas monitoring available in configured and modular monitors. The essential airway gas parameters include breath-by-breath CO2, O2, N2O values. A patented paramagnetic oxygen sensor provides both inspiratory and expiratory values with oxygram and difference of FiO2-EtO2. The five anesthetic agents, enflurane, halothane, isoflurane, sevoflurane and desflurane are automatically identified and analyzed breath-by-breath, even when mixed. Minimum Alveolar Concentration (MAC or age related MACage) of N2O and the monitored agent is calculated and the value can be displayed on the screen. 

There are several modular options available, even for high-acuity patients. Modules range from CO2 monitoring to a fully integrated module which includes airway gases, lung mechanics and gas exchange integrated in a single module.

Patient Spirometry

Patient Spirometry measures airway pressures, flow, volumes, compliance and airway resistance breath-by-breath at the patient airway with the patented D-lite flow sensor and gas sampler. Compliance and resistance are measured and PEEP and intrinsic PEEP are displayed separately. The dynamic inter-relationship between pressure and volume, or flow and volume, is displayed as graphical loops. 

Patient Spirometry values measured at the patient airway represent real patient values and are not influenced by ventilator hoses or other breathing system components. Patient Spirometry provides clinicians a tool to help detect changes in patient’s respiration and ventilatory status and to adjust optimal ventilator settings. 

Patient Spirometry information integrated and documented together with hemodynamic information in a single monitor provides an informed view of the patient’s cardio respiratory status to support treatment decisions. 

Gas Exchange

Direct pulmonary gas exchange measurement, also known as indirect calorimetry, allows continuous and non-invasive measurement of oxygen consumption (VO2), carbon dioxide production (VCO2), and calculation of respiratory quotient (RQ) and energy expenditure (EE). The gas exchange measurement is used with modular patient monitors both in anesthesia and critical care. 

Gas exchange and metabolic measurement provide a valuable clinical tool for diagnostic and therapeutic purposes varying from assessment of individual patient energy requirements and response to nutrition to analysis of ventilation and oxygen transport in critically ill patients. The modern technology enables a user friendly and continuous measurement. As a bedside module it provides a smooth setup without any pre-calibration and is thus operational when needed. Modularity allows switching the module between patients and brings flexibility and cost efficacy to the patient treatment.
