System and devices for monitoring a hemodynamic status of a patient

A system for monitoring a hemodynamic status of a patient, the system comprising:

• a transducer configured to couple to the patient and measure a hemodynamic status of the patient;
• a holder configured to couple the transducer to any of a plurality of differing mounting plates, each mounting plate including a first bracket arm and a second bracket arm that define a slot,
• wherein the slot has a slot width defined by a separation between the first bracket arm and the second bracket arm,
• wherein the plurality of differing mounting plates comprise slots having differing widths, and
• wherein the holder comprises a first flexible arm configured to engage the first bracket arm of a first mounting plate of the plurality of differing mounting plates and a second flexible arm configured to engage the second bracket arm of the first mounting plate, the first flexible arm and the second flexible arm configured to provide an outward force when depressed inwards towards a central axis of the transducer.
