Abstract

The present invention relates to a method (200), device (10), and system (100) for determining ambient atmospheric pressure of a non-invasive blood pressure measurement system (50). The method comprises: - obtaining a pressure difference measurement result comprising information about pressure differences over time between the inside of the NIBP measurement system and the ambient atmosphere as measured by a gauge pressure sensor of the NIBP measurement system; and - determining the ambient atmospheric pressure based on a predetermined mathematical model, wherein the predetermined mathematical model is based on the obtained pressure difference measurement result, performance parameters of a pump of the NIBP measurement system and one or more of: - an effective opening area of a valve and/or orifice of the NIBP measurement system if a valve and/or orifice of the NIBP measurement system is opened, - properties of a body part of a user and an actuator of the NIBP system if the actuator is attached to the body part, and - a volume of a rigid container if the NIBP measurement system comprises the rigid container, the rigid container at least replacing the actuator of the NIBP system.
