RESPIRATORY ANALYZER SYSTEM
A process of tar destruction in gasification of carbonaceous material comprising providing a mixture of finely divided calcium compound of a particle size smaller than 65 mesh and finely divided carbonaceous material of a particle size smaller than 65 mesh, the calcium compound to carbonaceous material ratio being from about 0.5 to 1.0 and contacting the mixture with CO2 and tar exothermally whereby the tar is destroyed.

A system for measuring the ventilatory response of the human respiratory system to increased levels of CO2 and/or decreased levels of 02. Measured concentrations of CO2 are introduced into an infant's lungs and the inspired and expired air is passed through a pneumotachograph for developing various electrical analog signals relating to flow. Samples of the expired air are delivered to CO2 and 02 analyzers. The resulting electrical analog signals produced by these devices represent inspiratory and expiratory flow, and the CO2 and the 02 levels in the expired air. They are applied to a waveform analyzer containing an analog to digital converter and a microprocessor system which is programmed to discriminate between normal breathing patterns and irregular patterns. The microprocessor also computes inspiratory and expiratory tidal volume, ventilation (measured in liters per minute), breathing frequency, inspiratory, expiratory and total times of a preceding breath, minimum CO2 and 02, peak CO2 and 02 and volume of expired CO2 and 02 either on a breath-by-breath basis or over a user selected time interval. The results of these computations are provided in digital form to a digital computer having a graphic display capability. When the ventilation rate is plotted as a function of changes in the inspired CO2 concentration, the slope of this linear relation is indicative of abnormal ventilatory response, which is deemed helpful in the diagnosis of a number of disease states, e.g., Sudden Infant Death Syndrome.

Optionally, the drive fluid can be saturated with carbon dioxide, nitrogen and/or natural gas at the injection pressure.
