Abstract: The invention relates to a device (1, 1′) and a method for obtaining an indicator of microcirculatory condition of a patient. The device (1, 1′) comprises at least one first sensor (13) for measuring data indicative of first carbon dioxide levels, in particular tissue carbon dioxide levels, at least one second sensor (12) for measuring data indicative of second carbon dioxide levels, in particular transcutaneously measured arterial blood carbon dioxide levels, and a control unit (4) for determining a measure of microcirculation, in particular changes in tissue perfusion, preferably in septic patients, on the basis of the tissue carbon dioxide level and the transcutaneously measured arterial blood carbon dioxide level.

Abstract: An insufflator for exposing structures within an internal cavity forming a confined volume within an animal or human body, the apparatus including: an input conduit for exchanging gas with the confined volume; a gas insufflator for insufflation of gas into the confined volume through the input conduit, wherein the gas insufflator is configured to deliver an insufflator pressure to the confined volume, wherein the gas insufflator is configured to (super)impose at least one pressure or flow oscillation to obtain a forced oscillating pressure or flow delivered to the confined volume, the forced oscillating pressure or flow having at least one component with a frequency and an amplitude; a monitoring unit for monitoring a response of the internal cavity to the forced oscillating pressure or flow for determining one or more physical properties of the internal cavity; and an adapter unit for adjusting the insufflation pressure based on the determined one or more physical properties of the internal cavity.
