What is one limitation of using a Bourdon Gauge?

The limitation of a Bourdon Gauge stemming from changes in pressure distal to the orifice is significant because Bourdon Gauges function by measuring the pressure applied to them through the deformation of a coiled tube. When the pressure on one side of the orifice changes—such as might occur during changes in flow or resistance downstream—it can lead to inaccuracies in the gauge reading. This is because the reading reflects the pressure only at the gauge itself and is not influenced by downstream changes, which can lead to a misunderstanding of the actual conditions in the system being measured.

In contrast, the other options do not accurately characterize the limitations of Bourdon Gauges. For instance, while it's true that these gauges can be less effective in certain measurement contexts, they are generally designed to handle a range of pressures, including large volumes, depending on the specific application. Additionally, Bourdon Gauges can be used to reflect variable pressures within certain limits, hence the confusion with that aspect of their functionality. They can also be utilized during patient transport, provided they are properly calibrated and suited for the specific setting. Thus, the ability to maintain accuracy regardless of pressure variations downstream is a key limitation that distinguishes the correct choice regarding Bourdon Gauges.
