Abstract: (EN) Respiration of a patient can be monitored by means of a device (ASD) that has the following characteristics. An inlet (IL) receives a pressurized airflow of breathable air from an airflow source. An outlet (OL) applies the pressurized airflow to a mask worn by the patient. An airflow path (AFP) is arranged between the inlet (IL) and the outlet (OL). The airflow path (AFP) has an axis (AX) and exhibits a decrease (??D) in diameter followed by an increase (+?D) in diameter in a direction from the inlet (IL) to the outlet (OL). The increase (+?D) in diameter comprises an initial portion (WI) in which the diameter increases according to a slope (?) of less than 10° with respect to the axis (AX). A pressure measurement arrangement (PS1, PS2) provides an indication (SO) of a pressure difference in the pressurized airflow between two sections (IN, T) of the airflow path that have different diameters.

From such information one or more breathing parameters of subject 12 (e.g., respiratory rate, end-tidal CO2, etc.) are determined, respiratory events (e.g., obstructions, apneas, etc.) are identified, equipment malfunction and/or misuse is identified, and/or functions are performed. To improve the accuracy of one or more of these determinations, information related to pressure at or near the airway of subject is implemented. This information may include detection of pressure at or near a sidestream sampling cell.

Abstract: A device for fractionally collecting contents of exhaled air by changing the state of matter of the contents by means of the Joule-Thomson effect arising during the expansion of pressurized gas. The temperature of the exhaled air conducted in a flow channel is lowered, because of the cooling of the expanding gas, to a temperature that is suitable for condensing the contents in the exhaled air flow. This device and method provides a more efficient means by which condensate can be separated from exhaled air in comparison to conveying exhaled air along a cooling surface for the condensation of the contents, as a result of which condensation of the contents occurs only in the area of these cooling surfaces, so that several breath cycles are required for the collection of sufficient condensate for analysis.

Abstract: A monitoring device receives a measurement signal obtained by a pressure sensor in an extracorporeal fluid system, such as an extracorporeal blood circuit for a dialysis machine which is in contact with a vascular system of a subject via a fluid connection. The monitoring device processes the measurement signal to identify pressure data that represents pulses originating from a first physiological phenomenon in the subject, excluding the heart of the subject. The first physiological phenomenon may be any of reflexes, voluntary muscle contractions, non-voluntary muscle contractions, a breathing system of the subject, an autonomous system of the subject for blood pressure regulation, or an autonomous system of the subject for body temperature regulation. The monitoring device may detect, present, track or predict a disordered condition of the subject using the pressure data, or monitor the integrity of the fluid connection based on the pressure data.

Abstract: A probabilistic digital signal processor for medical function is described. Initial probability distribution functions are input to a dynamic state-space model, which operates on state and/or model probability distribution functions to generate a prior probability distribution function, which is input to a probabilistic updater. The probabilistic updater integrates sensor data with the prior to generate a posterior probability distribution function passed to a probabilistic sampler, which estimates one or more parameters using the posterior, which is output or re-sampled in an iterative algorithm. For example, the probabilistic processor operates using a physical model on data from a medical meter, where the medical meter uses a first physical parameter, such as blood oxygen saturation levels from a pulse oximeter, to generate a second physical parameter not output by the medical meter, such as a heart stroke volume, a cardiac output flow rate, and/or a blood pressure.
