Apparatus and methods for detecting onset of cardiac arrest utilizing a perfusion monitor. Detecting cardiac arrest comprises transmitting a signal toward a user to interact with the skin of the user, receiving a reflection of the signal, generating a photoplethysmogram, and processing the photoplethysmogram to detect whether the user is experiencing cardiac arrest.

A medical treatment system for determining administration of medications to a patient is disclosed. The system uses a plurality of sensors to perform a first set of physiologic measurements in a right side of the heart and a second set of physiologic measurements in a left side of the heart. The system also includes a receiver configured to receive measurement data regarding the first and second sets of physiologic measurements and output to a display device the received measurement data.

The present invention may be embodied as a retrievable device capable of sensing one or more properties of an individual (e.g., chemical or physical parameters). In use, the retrievable device can continuously determine the chemical concentrations within the vaginal tract. An embodiment of the retrievable device comprises a first housing having a light source and an image capture device, a second housing removably connected to the lust housing and having a sensor, and a fitting for retrieving the device. The sensor may be an analyte sensor configured to obtain at least one measurement of a concentration of an analyte in a fluid. The analyte sensor comprises a sensor substance in a sol-gel material so the sensor substance reversibly interacts with an analyte of interest. In addition, the retrievable device can be configured to determine different physical parameters and re-implanted.

Various methods and apparatuses are presented for an ingestible capsule that includes a digital, ingestible sensor component—or ingestible sensor—embedded into the capsule. The ingestible sensor component may be configured to activate upon coming into contact with conductive fluid, such as a body's stomach fluid. Once activated, the ingestible sensor component may be configured to perform various tasks, such as transmitting one or more signals and obtaining biometric data about the body that ingested the capsule.
