摘要:
This invention relates to a breath indicator that is receivable by a part of a breathing assistance apparatus that supplies gas to a patient. The indicator comprises an elongate body having a gas sampling end and an attachment end. The attachment end is adapted to attach to a part of a breathing assistance apparatus and for locating the gas sampling end. The gas sampling end is to be located in a region where gas from the patient is to be exhaled. The gas sampling end being in communication with a sensor comprising a detector material changeable between a first visual indicator state relating to an inhalation phase of the patient, and a second visual indicator state relating to an exhalation phase of the patient. The detector material is capable of changing between the visual indicator states at a sufficient rate to substantially correspond with the inhalation and exhalation phases of the patient.
