1. An apparatus, comprising:
a fluid conduit configured to receive a volume of fluid from a patient;
a container fluidically coupled to the fluid conduit, the container defining a reservoir configured to receive the volume of fluid from the fluid conduit;
a vacuum conduit couplable to a vacuum source;
a vent configured to vent air into the reservoir, the vent having a cross-sectional area of between about 0.05 mm2 and about 1.5 mm2; and
at least one valve configured to:
couple the reservoir to the vacuum conduit to generate negative pressure within the reservoir such that the volume of fluid is drawn into the reservoir; and
decouple the reservoir from the vacuum conduit while coupling the reservoir to the vent such that air is vented into the reservoir at an average rate that prevents turbulent movement of the volume of fluid within the reservoir.
