    摘要： A system for sensing respiratory pressure includes a portable pressure transducer configured to be carried by or proximate to a respiratory conduit, such as a breathing circuit or a nasal canula. The portable pressure transducer may removably couple with a pneumotach, in the form of an airway adapter, disposed along the respiratory conduit. The pneumotach may include two pressure ports positioned at opposite sides of an obstruction, which partially blocks flow through a primary conduit of the pneumotach. Corresponding sample conduits of the portable pressure transducer removably couple with the pressure ports. The pressure ports may have sealing elements which are configured to seal against piercing members of the sample conduits upon introduction of the piercing members therethrough. Upon removal of the piercing members, the sealing elements substantially reseal. Methods for using the system are also disclosed.

    摘要： A calorimeter configured to determine a metabolic rate of an individual based on measurements of the individual's respiration. The calorimeter includes an inlet, a flow sensor, a mixing chamber, a gas sensor, and a calibrator. Each of these elements is located along a flow path through the calorimeter. The calibrator of the calorimeter includes a fan that is configured to force calibration gases, such as room air, through or past the gas sensor. A cardiac rate monitor is associated with a processor of the calorimeter. The processor is configured to substantially simultaneously determine and establish a relationship between the cardiac rate of the individual and the measured respiratory parameters or the metabolic rate of the individual. Data representative of this relationship may be communicated to a processor or memory of a portable calorimeter to be subsequently used by the individual. The portable calorimeter, which can be worn by the individual, includes a cardiac rate monitor that measures the cardiac rate of the individual and communicates data representative of the individual's cardiac rate to the processor, which then determines the metabolic rate of the individual based on relationship data obtained from the respiratory-based calorimeter. Methods of calibrating and using the calorimeters are also disclosed.

    摘要： A peak flow monitoring system having a base unit and a flowhead. The flowhead is designed for roll and snap connection to the base unit so as to be easily removable therefrom after use for ease of cleaning and storage. A gasket compressed between the flowhead and a pressure transducer housed in the base unit forms a pneumatic seal between the two when the flowhead is connected to the base unit, providing a minimal dead volume therebetween. Pressure in the flowhead generated by patient exhalation therethrough is measured by the base unit pressure transducer and a microprocessor computes pulmonary function parameter values from the transducer output for storage and display. The base unit display function includes text-based, customizable, reconfigurable patient symptom and medication queries. Methods of system assembly, disassembly and operation are also disclosed.
