Abstract: A cardiopulmonary resuscitation, CPR, device (100, 200, 400) for delivering intrathoracic pressure pulses to a subject (290), the device comprising an air pressure generator (110, 310, 410) for delivering air to the airways of the subject (290), wherein the air pressure generator (110, 310, 410) is configured to: operate a first mode, wherein in the first mode the air pressure generator (110, 310, 410) generates a first output (412, 770a, 770b) comprising a first plurality of positive pressure pulses (771) for temporally increasing the subject's intrathoracic pressure to induce compressions of the heart of the subject (290) by increasing the volume of the subject's lungs; operate a second mode, wherein in the second mode the air pressure generator (110, 310, 410) generates a second output (414, 880) comprising a second plurality of positive pressure pulses for providing an assured airflow to the lungs of the subject (290); and deliver a resulting output (425, 986, 1086) to the airways of the subject (290), the resulting output being the superposition of the first output (412, 770a, 770b) and of the second output (414, 880); wherein said first plurality of positive pressure pulses (771) have an amplitude greater than 30 mbar and a frequency in a range of 40-240 beats per minute; and wherein said second plurality of positive pressure pulses have an amplitude smaller than 30 mbar and a frequency in a range of 3 to 20 cycles per minute.

Abstract: A system (100) includes an imaging system (102) and a pressure delivery system (104). The imaging system includes a data acquisition system (114 and 116) and is configured to produce data. The pressure delivery system is configured to produce a periodic airflow variation. The system further includes an operator console (120) configured to control the imaging system to scan a subject receiving the periodic airflow variation and map the periodic airflow variation and first data. The system further includes a reconstructor (516) configured to reconstruct the first data and generate first volumetric image data indicative of the periodic airflow variation.

Abstract: Various systems, apparatus and methods are described herein for generating cardiac, cardiopulmonary, and/or hemodynamics phenotypes of patients for use in various applications. In various embodiments, a ventilation support apparatus connected to a patient may be operated to perform a therapeutic maneuver selected to cause one or more targeted receptors of the patient to initiate an autoregulation response in the patient. In various embodiments, a measurement may be taken of one or more changes in a vital sign of the patient such as blood pressure that is caused by initiation of the autoregulation response in the patient. In various embodiments, a cardiac, cardiopulmonary, or hemodynamic phenotype of the patient may be generated based on the measured one or more changes.
