verifying that the detected cuff size is consistent with the expected cuff size; and controlling inflation of the blood pressure cuff based on the expected cuff size. ### Claim 2 (depends on 1) The system of claim 1, wherein the cuff verification module is further executable on the processor to generate an error alert if the detected cuff size is not consistent with the expected cuff size. ### Claim 3 (depends on 1) The system of claim 1, wherein the expected cuff size is a range of cuff sizes based on the age of the patient, and the cuff verification module verifies that the detected cuff size is within the range of cuff sizes. ### Claim 4 (depends on 3) The system of claim 3, wherein the range of cuff sizes is one of a neonatal cuff size range, an infant cuff size range, and an adult cuff size range. ### Claim 5 (depends on 1) The system of claim 1, wherein the medical record information further includes one or both of a height and weight of the patient, wherein the cuff verification module is further configured to select the expected cuff size from a list of possible cuff sizes accessible by the cuff verification module based on the age of the patient and at least one of the height and weight of the patient, wherein each possible cuff size in the list of possible cuff sizes is associated with two or more of an age range, a height range, and a weight range. ### Claim 6 (depends on 1) The system of claim 1, wherein the medical record information further includes previous cuff size for the patient, and wherein the expected cuff size is determined based further on the previous cuff size. ### Claim 7 (depends on 1) The system of claim 1, wherein the cuff verification module is further configured to: control the blood pressure measurement device to pump a predetermined amount of air into the blood pressure cuff and measure a pressure change in the blood pressure cuff; compare the pressure change with an expected pressure change for the expected cuff size; and generate an error alert if the pressure change is not within a predetermined range of the expected pressure change. ### Claim 8 (depends on 1) The system of claim 1, wherein the cuff verification module is further configured to: determine a maximum expected fill amount based on the expected cuff size; control the blood pressure measurement device such that an amount of air pumped into the blood pressure cuff does not exceed the maximum expected fill amount. ### Claim 9 (depends on 1) The system of claim 1, wherein the cuff verification module is stored on memory in the blood pressure measurement device and the processor is contained in the blood pressure measurement device. ### Claim 10 (depends on 1) The system of claim 1, further comprising identifier means for identifying a cuff size of the blood pressure cuff, and detector means for detecting the identifier means. ### Claim 11 A method of monitoring blood pressure of a patient, the method comprising: receiving medical record information for the patient at a processor of a blood pressure measurement device, wherein the medical record information includes an age of the patient; performing a cuff verification process, including, for each cuff verification: calculating, at the processor, an expected cuff size for the patient based on the age of the patient obtained from the medical record information; receiving, at the processor, a detected cuff size of a blood pressure cuff for use on the patient; comparing, at the processor, the detected cuff size to the expected cuff size; and verifying, at the processor, that the detected cuff size is consistent with the expected cuff size; and controlling inflation of the blood pressure cuff by the blood pressure measurement device based on the expected cuff size. ### Claim 12 (depends on 11) The method of claim 11, further comprising generating a positive verification alert if the detected cuff size is consistent with the expected cuff size, or generating an error alert if the detected cuff size is not consistent with the expected cuff size. ### Claim 13 (depends on 11) The method of claim 11, further comprising, if the detected cuff size is consistent with the expected cuff size, automatically inflating the blood pressure cuff to measure a blood pressure of the patient. ### Claim 14 (depends on 12) The method of claim 12, wherein the expected cuff size is a range of cuff sizes based on the age, and wherein the detected cuff size is determined to be consistent with the expected cuff size if the detected cuff size is within the range of cuff sizes. ### Claim 15 (depends on 11) The method of claim 11, wherein the medical record information further includes one or both of a height and a weight of the patient. ### Claim 16 (depends on 15) The method of claim 15, wherein the step of determining the expected cuff size includes selecting, at the processor, from a list of possible cuff sizes stored in a storage system of the blood pressure measurement device based on the age and at least one of the height and the weight of the patient, wherein each possible cuff size in the list of possible cuff sizes is associated with two or more of an age range, a height range, and a weight range. ### Claim 17 (depends on 11) The method of claim 11, further comprising: controlling the blood pressure measurement device to pump a predetermined amount of air into the blood pressure cuff and measure a pressure change in the blood pressure cuff; comparing the pressure change with an expected pressure change for the expected cuff size; and generating an error alert if the pressure change is not within a predetermined range of the expected pressure change. ### Claim 18 (depends on 11) The method of claim 11, further comprising: determining a maximum expected fill amount based on the expected cuff size;
