1. An inflation apparatus for use in an inflation-based non-invasive blood pressure (NIBP) measurement apparatus, the inflation apparatus comprising: an outlet configured to be coupled to a cuff of the inflation-based NIBP measurement apparatus; a plurality of pumps each configured to output a respective flow of gas to the outlet to produce a flow of gas at the outlet for inflating the cuff; and a control unit comprising a processor and configured to: (i) enable at least one of the plurality of pumps to output a respective flow of gas to the outlet, wherein a number of the plurality of pumps enabled by the control unit is based on a required flow rate of gas at the outlet for inflating the cuff, and/or (ii) control at least one of the plurality of pumps to output a respective flow of gas to the outlet at a respective flow rate, wherein the respective flow rate of the at least one of the plurality of pumps is controlled based on the required flow rate, wherein the required flow rate is determined based on at least one of a required rate of change of pressure in the cuff and a compliance value of the cuff.
