A device for determining measurement values describing the function of the lungs or the respiratory system of a patient includes a mouthpiece including a tube for introducing respiratory air and for sucking in air, and a gas measurement space. At least one of the following gas sensors is arranged in the gas measurement space: nitrogen monoxide sensor, carbon dioxide sensor, oxygen sensor, carbon monoxide sensor, multi-gas sensor, sensor for volatile organic compounds, alkane sensor, infrared sensor, fiber optic sensor, resistance sensor, and semiconductor sensor. The gas measurement chamber is separated by a closable opening into a first gas measurement chamber and a second gas measurement chamber, the second gas measurement chamber being closed or closable. The closable opening opens a flow path from the first gas measurement chamber into the second gas measurement chamber. A gas sensor is arranged in the second gas measurement chamber.

A system and method for preliminarily identifying a medical condition in a monitored patient. A predetermined set of patient physiological parameters that are indicative of the presence of a medical condition is monitored. If all of the patient physiological parameters meet a predetermined criteria, a notification is activated that is indicative of the presence of the medical condition. Optionally, users are provided with guidance concerning additional patient physiological parameters to be checked to confirm the presence of the medical condition.

The present specification discloses systems and methods of patient monitoring in which multiple sensors are used to detect physiological parameters and the data from those sensors are correlated to determine if an alarm should, or should not, be issued, thereby resulting in more precise alarms and fewer false alarms. Electrocardiogram readings can be combined with invasive blood pressure, non-invasive blood pressure, and/or pulse oximetry measurements to provide a more accurate picture of pulse activity and patient respiration. In addition, the monitoring system can also use an accelerometer or heart valve auscultation to further improve accuracy.

An article of manufacture for providing a CO.sub.2 monitoring smart facemask assembly according to the present invention includes_a CO.sub.2 sensor component having a CO.sub.2 sensor, a serial data connection, and a power connection, a set of connecting wires, and_a controller unit coupled to the CO.sub.2 sensor component by the set of connecting wires. The controller unit includes a programmable microcontroller, the programmable microcontroller receives a measure of a current CO2 value from the CO.sub.2 sensor component, a battery, one or more visual alarm devices; and_an auditory alarm device and an alarm reset button 207. The microcontroller activates the one or more visual alarm devices and the auditory alarm devices when the current CO.sub.2 value is greater than a pre-defined threshold. This warning will ensure safety of the user and an option to shut the alarm off, thereby after the warning has been acknowledged. The one or more visual alarm devices include one or more LEDs and a display device. The display device shows an alpha-numeric representation of the current CO.sub.2 value measured by the CO.sub.2 sensor component.

An oxygen facemask that has pathogen filtering capability can be used in conjunction with a capnometer to measure carbon dioxide levels in a patient. Facemask can be used to provide critical breathing assistance to patients. In certain instances, a patient’s blood CO2 level can be the difference between a good versus a bad outcome. Accordingly, in certain circumstances there is great value in evaluating a patient’s CO2 with a capnometer from breath exiting the facemask, which correlates to CO2 in their blood. Because some of these patients carry airborne transmissible viruses, an exhalent filtration system is envisioned included in the facemask that filters the patient’s breath from those helping the patient in a common space. The exhalent filtration system incorporates both filtering air exiting the facemask directly into a common space and indirectly into the common space by way of the capnometer.
