Hyperbaric-Capable Spirometer

Hyperbaric chambers are highly pressurized, highly oxygenated environments in which physicians need reliable, hands-free spirometers for their ventilated patients. As a patient exhales, the moving air exerts a pressure. This hyperbaric-capable spirometer measures this applied pressure through a pitot tube to continuously calculate the tidal volume and breathing rate of a patient. Additionally, the device measures the carbon dioxide concentration of a patient's exhaled breath to ensure the patient is metabolizing healthily. All values are automatically displayed to healthcare providers via an LCD display screen. The device is designed to be accurate at all pressures up to 6 ATM and meets all structural and electrical requirements for use in hyperbaric chambers.
