This disclosure describes systems and methods for providing a high pressure controlled proportional assist ventilation breath type during ventilation of a patient. The disclosure describes a novel breath type that reduces ventilator support (or a percent support setting) based on the occurrence of a predetermined number of high pressure alarms.

The present disclosure relates to a method for continuous and noninvasive estimation of mixed venous blood saturation [SvO2] in a mechanically ventilated subject (3). The method comprises the steps of measuring (S1; S10) an expiratory carbon dioxide [CO2] content in expiration gas exhaled by the subject, measuring (S2; S20) an expiratory flow or volume of expiration gas exhaled by the subject, estimating (S3; S30) a cardiac output [CO] or an effective pulmonary blood flow [EPBF] of the subject from the measured expiratory CO2 content and the measured expiratory flow or volume using a capnodynamic Fick method, and estimating (S4; S40) SvO2 based on the estimated CO or the EPBF of the subject.

In general, systems for administering a dmg are provided. In an exemplary embodiment, a dmg administration system includes a dmg administration device configured to communicate with a computer system and at least one sensor configured to obtain sensor data and communicate the sensor data to the drug administration device. The dmg administration device is configured to utilize a first drug dosing scheme when a drug is delivered to a patient, determine a second drug dosing scheme for delivering a drug to the patient dependent on dosing data from the computer system and sensor data collected by the sensor during and/or after the delivery of the first drug according to the first drug dosing scheme, and utilize the second drug dosing scheme when the drug is delivered to the patient.

An intelligent psychological assessment and intervention system based on an independent space, comprising a psychological intervention cabin and a central database which achieves data interaction with the psychological intervention cabin. The psychological intervention cabin comprises a housing, a data acquisition module, a data processing module, and an intervention module; the data acquisition module acquires physiological and psychological data of a subject; the data processing module performs operations on the acquired data, establishes a multi-dimensional state point of the subject according to a mathematical model of the data processing module, matches it with data in the central database, finds a suitable intervention procedure for the subject, and guides the intervention module to carry out intervention; in the intervention process, the data acquisition module continuously acquires the physiological and psychological data of the subject, and the data processing module forms a new multi-dimensional state point according to new data and re-matches it to adjust the intervention procedure. By repeating this cycle, the intervention procedure is continuously adjusted in the intervention process to seek a most suitable intervention solution for the subject, and an optimal intervention effect is achieved.
