The invention is claimed as follows: 1. An intraperitoneal pressure ("IPP") measurement system comprising: a fluid container containing peritoneal dialysis ("PD") fluid; a transfer set and catheter in fluid communication with the fluid container and configured to fluidly communicate with a patient's peritoneal cavity to enable PD fluid to be provided to the patient's peritoneal cavity; a pressure sensor configured to contact the transfer set or the catheter, the pressure sensor configured to transmit output data indicative of an IPP within the patient's peritoneal cavity, the pressure sensor including a pressure element configured to measure a pressure imparted by a fluid within the transfer set or catheter, and a pressure amplifier (504, 602) having a first side that contacts a portion of the transfer set or catheter and a second side that contacts the pressure element, the first side having a greater diameter or surface area compared to the first side; and a processor communicatively coupled to the pressure sensor, the processor configured to receive the output data indicative of the IPP within the patient's peritoneal cavity, receive force data indicative of at least one of patient movement or pressure sensor movement, spirometry data indicative of the patient's lung capacity, or patient information including at least one of urine output within a defined time period, food/beverage intake within a defined time period, a heart rate, or a blood pressure, adjust the output data indicative of the IPP using the force data, the spirometry data, or the patient information, and at least one of use the adjusted output data indicative of the IPP to determine a fill volume parameter for a PD treatment for the patient, or cause the adjusted output data indicative of the IPP to be displayed to enable a determination of the fill volume parameter. a fluid container containing peritoneal dialysis ("PD") fluid; a transfer set and catheter in fluid communication with the fluid container and configured to fluidly communicate with a patient's peritoneal cavity to enable PD fluid to be provided to the patient's peritoneal cavity; a pressure sensor configured to contact the transfer set or the catheter, the pressure sensor configured to transmit output data indicative of an IPP within the patient's peritoneal cavity, the pressure sensor including a pressure element configured to measure a pressure imparted by a fluid within the transfer set or catheter, and a pressure amplifier (504, 602) having a first side that contacts a portion of the transfer set or catheter and a second side that contacts the pressure element, the first side having a greater diameter or surface area compared to the first side; and a pressure element configured to measure a pressure imparted by a fluid within the transfer set or catheter, and a pressure amplifier (504, 602) having a first side that contacts a portion of the transfer set or catheter and a second side that contacts the pressure element, the first side having a greater diameter or surface area compared to the first side; and a processor communicatively coupled to the pressure sensor, the processor configured to receive the output data indicative of the IPP within the patient's peritoneal cavity, receive force data indicative of at least one of patient movement or pressure sensor movement, spirometry data indicative of the patient's lung capacity, or patient information including at least one of urine output within a defined time period, food/beverage intake within a defined time period, a heart rate, or a blood pressure, adjust the output data indicative of the IPP using the force data, the spirometry data, or the patient information, and at least one of use the adjusted output data indicative of the IPP to determine a fill volume parameter for a PD treatment for the patient, or cause the adjusted output data indicative of the IPP to be displayed to enable a determination of the fill volume parameter. receive the output data indicative of the IPP within the patient's peritoneal cavity, receive force data indicative of at least one of patient movement or pressure sensor movement, spirometry data indicative of the patient's lung capacity, or patient information including at least one of urine output within a defined time period, food/beverage intake within a defined time period, a heart rate, or a blood pressure, adjust the output data indicative of the IPP using the force data, the spirometry data, or the patient information, and at least one of use the adjusted output data indicative of the IPP to determine a fill volume parameter for a PD treatment for the patient, or cause the adjusted output data indicative of the IPP to be displayed to enable a determination of the fill volume parameter.
