Portable Hand-Held Alveolar Oxygen and Carbon Dioxide Meter

技術應用

This device has numerous applications and will be particularly valuable: In monitoring asthma and COPD in a pulmonologist’s office and/or by an individual patient at home (even one receiving oxygen). At exercise rehabilitation facilities by exercise physiologists. In emergency rooms. On the floor of a hospital. In ambulances by EMT personnel. At high altitudes for following the process of acclimatization.

詳細技術說明

This invention is a portable alveolar oxygen and carbon dioxide meter that shows the concentration or partial pressures of oxygen and/or carbon dioxide in the alveolar gas in the depths of the lung. It is the first portable oxygen meter and would compete only with pulse oximeters. However, pulse oximeters measure the oxygen saturation of the hemoglobin in the blood and this type of measurement does not give an accurate estimate of the alveolar oxygen content of the lung. Alveolar content is important information, useful in assessing the efficiency of respiration, especially the level of ventilation.

Title: Portable alveolar gas meter
Usefulness: Portable alveolar gas meter
Summary: For measuring level of alveolar gas, such as oxygen, carbon dioxide of patient for conducting non-invasive test in variety of environment e.g. emergency department of hospital, paramedical ambulance, high altitude environment, such as telescopic facility, mines as well as in physical fitness/sport science environment, such as skiing, bicycle racing in high altitude in scuba-diving. Also applicable for alveolar gas measurement for animals.
Novelty: Portable alveolar gas meter, e.g. used paramedical ambulance, comprises oxygen sensor that outputs voltage signal indicating level of oxygen in sample of patient's breath, to indirectly determine carbon dioxide level
