A system and a method for automatically and continuously measuring and assessing hemodynamics uses fluorescence imaging in which the fluorescent agent is controlled and automated. A method of automatic perfusion assessment of an anatomical structure of a subject includes administration into a vein of a bolus corresponding to less than 0.01 mg ICG/kg body weight of a first fluorescence imaging agent. A system for automatic perfusion assessment during a medical procedure includes a controllable injection pump for holding at least one first fluorescence imaging agent, the injection pump being configured for injecting a predefined amount of the first fluorescence imaging agent into the blood. The system is configured for receiving and analysing a time series of fluorescence images and determining at least one perfusion parameter based on the analysis.

A computer-implemented method and corresponding output generator for handling alarm events, generated by a subject/patient monitoring device, and generating clinician-perceptible outputs indicative of the alarm events. Alarm events are divided into non-actionable and actionable alarm events. Information on non-actionable alarm events is stored. Stored information on non-actionable alarm events is contained in a clinician-perceptible output generated in response to detecting an actionable alarm event.

Various systems, devices, and methods are disclosed herein for treating acute myocardial infarction (AMI) patients using a heart pump controlled in a manner that maximizes mechanical unloading of the left ventricle in the presence of cardiovascular instability and minimizes myocardial oxygen consumption (MVO2) and consequentially infarct size to prevent the development of subsequent heart failure. In a closed feedback system, the system can include a sensor configured to generate an output used to measure or calculate a left ventricular systolic pressure (LSVP) within the left ventricle of a heart and a controller coupled to a heart pump. The controller can be configured to measure or calculate the LVSP based on the output of the sensor and to control an operation of the heart pump to maximize mechanical unloading of the left ventricle based on the measured or calculated LVSP.

A method for detecting the status of a caregiver with respect to one or more patients or detecting possible caregiver impairment includes monitoring an environmental aspect of the patient. The monitored environmental aspect is at least one of caregiver physical activity, caregiver physiological state, and patient surroundings. The method assesses conformance/nonconformance of each monitored aspect relative to a specified norm for that aspect. If the assessment of conformance/nonconformance indicates an intuitive concern of the caregiver or a possible impairment of the caregiver, the method issues a signal to a destination which indicates the possible concern or impairment. A system for carrying out the method includes a sensing subsystem, a processor, and machine readable instructions. The machine readable instructions, when executed by the processor, cause the system to identify, in response to information sensed by the sensing subsystem, the possibility of caregiver concern or impairment.

A process and a signal processing unit determine a pneumatic parameter (P.sub.mus) for the spontaneous breathing of a patient. The patient is ventilated mechanically by a ventilator. A lung-mechanical model (20) and a gradient model (22) are preset. The lung-mechanical model (20) describes a relationship between the pneumatic parameter (P.sub.mus) as well as a volume flow signal (Vol), a volume signal (Vol) and/or a respiratory signal (Sig), which can be measured. The gradient model (22) describes a value for the pneumatic parameter (P.sub.mus) as a function of N chronologically earlier values of the pneumatic parameter (P.sub.mus) or of a variable correlating with the pneumatic parameter (P.sub.mus). N values for the correlating variable are determined at first. At least one additional value is subsequently determined for the pneumatic parameter (P.sub.mus). N chronologically earlier values of the correlating variable, current signal values, the lung-mechanical model (20) and the gradient model (22) are used for this purpose.

An asset tracking system includes a camera adapted to capture images and output signals representative of the images. The camera may include one or more depth sensors that detect distances between the depth sensor and objects positioned within the field of view of the one or more cameras. A computer device processes the image signals and or depth signals from cameras and determines any one or more of the following: (a) whether a patient care protocol has been properly followed; (b) what condition a patient is in; (c) whether an infection control protocol has been properly followed; and (d) whether steps have been taken to reduce the risk of a patient from falling. Alerts may be issued if any conditions of importance are detected.

A novel clinical decision support system (CDS) helps the clinician setup, maintain, and interpret aesophageal pressure measurement. The esophageal pressure CDS (Pes CDS) would remind the clinician to do an occlusion test whenever the balloon is first inserted or changes dramatically. It could monitor the occlusion test and provide feedback on the performance and success of the occlusion test. Changes in the patient or monitored data can be tracked by looking for changes in the balloon baseline pressure, changes in the amplitude of the pressure waveform, or changes in the pattern of the Pes waveform. Having information from the ventilator will further increase the ability of the system to determine when Pes is changing unexpectedly.

Systems and methods for vital sign monitors are disclosed herein. In some cases, a warning score is calculated based on first measurements of a first biological condition and second measurements of a second biological condition. In particular cases, the first measurements and the second measurements are automatically measured during the same time period. The warning score may be calculated based on an average of the first measurements and an average of the second measurements. Based on determining that the warning score is outside of a predetermined range, a clinical device may output an alert.

A urinary catheter is described that can be retained inside the body for extended periods. A catheter mating device can connect to the catheter to move the catheter inside of the body or remove it from the body. The catheter includes one or more of: (1) a retention portion having an outer cover, an inner cavity, and at least one structure in the inner cavity that exerts outward force on the outer cover, and (2) an extendable flap at the catheter's distal end. The retention portion and/or extendable flap each are configured to retain the catheter in the proper position inside of a user's body.

A method and system for assisting clinicians in determining when and how to perform a lung recruitment procedure. The method includes a user configurable interface that an operator or institution can set up to correspond to best practices. Based upon the information entered into the configurable user interface, a method and algorithm automatically determines when a lung recruitment procedure should be instituted. The system can either manually or automatically enable the beginning of the lung recruitment procedure depending upon the clinician and facility preferences. The algorithm includes a plurality of process steps that are carried out in a clinically-relevant order to eliminate patient condition options and to provide the appropriate recommended actions prior to initiating the lung recruitment procedure.
