Respiration Rate Measurement

Analog Devices offers a variety of signal chain components and integrated solutions to convert thoracic impedance changes into a respiration rate measurement. Select solutions allow flexible chest electrode arrangements to optimize respiration rate measurement dependent on patient position and other system considerations. Other solutions include 4-wire capability and/or postprocessing and meter-on-chip capability that can help measurement resolution and robustness during patient movement. Identifying small thoracic impedance changes accurately requires very low noise precision components. ADI’s low noise, high frequency impedance-to-digital converters simplify respiration rate measurement—a critical vital sign.
