摘要： A heat and moisture exchange (HME) unit including a housing, a heat and moisture retaining media (HM media), and a resistance indicator. The housing forms a first port, a second port, and an intermediate section. The intermediate section extends between the first and second ports, and defines a flow path fluidly connecting the first and second ports. The HM media is maintained within the intermediate section along the flow path. The resistance indicator is carried by the housing and is fluidly connected to the first port. In this regard, a visual appearance of the resistance indicator changes as a function of pressure within the housing to visually alert a caregiver as to possible existence of an excessive pressure differential condition within the HME unit.
