ABSTRACT:
A spirometric device for connection to the respiratory piping system of a patient and wherein a delivery pickup system is situatable on an exhalation branch of the system. The signals transmitted by a pressure pickup included in the device and situated on the respiratory system and those transmitted by the delivery pickup are led to a computing and measuring assembly which integrates the delivery signals while correcting these as a function of the pressure variations and/or of the errors caused by the gas contained in the respiratory system.
