ProblemSolution
WhatcanIdoiftherespirationmeasurementfails?●Relearnrespiration.
●Checkelectrodequalityandpositioning.
●Adjustthebreathdetectionsensitivity.During
ventilator-supportedbreathing,therespiration
calculationmaycountonlyventilator-produced
inspirationsandexpirations.
●Otherelectricaldevicesmayinterferewiththe
