A decision support system is provided for the management of extubation in intensive care unit patients. Based on multi-organ variability analysis of physiological signals, the proposed system transforms acquired waveforms into clinical information such as the risk of failing extubation and the probability of passing extubation. Furthermore, a variety of mechanisms are provided for displaying the extracted information to support a clinician's decisions.

3D cine MR angiography systems and methods are disclosed for use during the steady state intravascular distribution phase of ferumoxytol. The 3D cine MRA technique enables improved delineation of cardiac anatomy in pediatric patients undergoing cardiovascular MRI.

Embodiments described herein include sensors and sensor systems having probe-off detection features. For example, sensors and physiological monitors described herein include hardware and/or software capable of providing an indication of the integrity of the connection between the sensor and the patient. In various embodiments, the physiological monitor is configured to output an indication of a probe-off condition for an acoustic sensor (or other type of sensor). For example, in an embodiment, a signal from an acoustic sensor is compared with a signal from a second sensor to determine a probe-off condition.

The invention is about a next-generation blood pump that provides pulsatile blood flow, and has been developed for cardiopulmonary by-pass devices used for maintaining extracorporeal blood circulation during heart surgeries and the supportive devices of circulation system. This device is technically a sort of synchronous power-assisted motor employing direct driver technology. The mentioned blood pump contains a rotor rotating on a magnetic bearing without a shaft and through the helical wings placed into the rotor it provides pulsatile blood supply adequate for the body requirement synchronous with the ECG signals received from the patients. It provides a patient safer and controlled pulsatile blood flow while running at high efficiency.
