Abstract: Apparatus, systems, and methods are provided for monitoring the extravascular lung water status of a patient. For example, an acoustic diagnostic device is provided that includes a housing configured to be worn by a patient and including a patient contact surface configured to contact the patient's skin of the patient's thorax; an acoustic transducer for transmitting acoustic energy via the patient contact surface into the patient's thorax and receiving reflected acoustic energy from the patient's thorax; and one or more processors coupled to the acoustic transducer for analyzing the reflected acoustic energy to provide an indication of extravascular lung water status of the patient.

Abstract: The invention provides a sanitization tracking and alerting system and method that automatically monitors hand sanitization actions of workers within a facility and reminds them of violations of hand sanitization requirements. The sanitization system may comprise a communications network providing interaction between a central computer with a database and one or more sanitizer dispenser systems, which dispense a sanitizer to the workers upon demand. The sanitizer dispensing system may have a reader for reading an identification device associated with the worker and a motion detector that detects when the worker is in the proximity of the dispensing mechanism.
