Methods, systems and apparatus for inducing and verifying the level of neural entrainment at any target frequency, through a combination of biofeedback mechanisms, data analysis, and modulation of synergistic combinations of adaptable stimuli.

A peritoneal dialysis system for detecting peritonitis is disclosed herein. In one example, an impedance measurement system includes an impedance monitor configured to sense an impedance of peritoneal dialysis (“PD”) fluid residing within a fluid line. The impedance monitor includes a first conductive lead disposed within a first port along the fluid line and a second conductive lead disposed within a second port along the fluid line. The impedance measurement system also includes a control unit electrically coupled to the impedance monitor. The control unit uses the sensed impedance from the impedance monitor to detect white blood cells to form a patient peritonitis determination. The control unit may communicate the peritonitis determination to alert a clinician.

This invention generally provides two tactile stimulation modules, or “tappers”. One tapper is held by a person in each of his hands. Alternatively, a tapper is secured to each wrist or to other parts of the body on opposite sides. Each tapper is powered by a rechargeable battery, and contains both a tactile stimulation transducer, such as an electric motor having either a balanced or unbalanced mass on its output shaft, and a transceiver that communicates with a host or master. Each tapper includes at least one control button and a status indicator. Each tapper contains a micro-controller that performs tasks such as communication, motor activation, user monitoring and control, battery monitoring, low-power sleep, and algorithm execution. At least one tapper can contain at least one optional sensor, which measures a physiological function. Measurements can be used to modify performance of the tactile stimulation transducers.

An apparatus for a heart of a patient having a cardiac assist device adapted to be implanted into the patient to assist the heart with pumping blood. The apparatus has a sensor adapted to be implanted into the patient. The sensor in communication with the cardiac assist device and the heart which measures native volume of the heart. Alternatively, the sensor monitors the heart based on admittance while the cardiac assist device. Alternatively, the sensor monitors the heart based on impedance.

A plurality of flow rate values associated with pressurized air directed to an airway of a user of a respiratory therapy system is received. A plurality of pressure values associated with the pressurized air directed to the airway of the user is received. A first time associated with a first breath of the user and a second time associated with a second breath of the user are identified. The plurality of flow rate values is filtered based at least in part on the identified first time and the identified second time. The filtering produces a subset of the plurality of flow rate values. An intentional leak characteristic curve for the respiratory therapy system is determined using at least two of the subset of the plurality of flow rate values and the corresponding pressure values for said at least two of the subset of the plurality of flow rate values.

The present disclosure is directed to devices, systems, and methods for sensing and discerning whether a distal portion of a fat grafting cannula or probe is disposed in fat tissue or muscle tissue during fat grafting procedures. In one aspect of the present disclosure, a fat grafting cannula or probe is provided including first and second electrodes. Each electrode is coupled to a circuit, e.g., disposed in an electrosurgical generator. During a fat grafting procedure, the electrodes contact patient tissue. Based on signals received from each electrode, the circuit is configured to determine whether a distal portion of the fat grafting cannula is disposed in a fat tissue or muscle tissue. If the circuit determines that the fat grafting cannula is disposed in muscle tissue, the surgeon operating the fat grafting cannula is alerted to ensure that processed fat is not injected into the muscle tissue of the patient.

Transdermal electrical stimulation (TES) applicators that are wearable and configured to attached to a subject's pinna (ear) and adapted to apply TES to modulate the subject's cognitive and/or physiological state. These apparatuses may be configured so that they can be worn against the ear (e.g., the cymba of the ear) to deliver TES. Also described herein are methods of using them to modulate a subject's cognitive state. These TES applicators may also be adapted to function as audio headphones for concurrent delivery of TES and audible signals (e.g., music).

Provided are methods comprising presenting a sensory environment to an individual experiencing the effects of a psychoactive agent, monitoring the neural status, the physiological status, or both, of the individual, and presenting a modified sensory environment to the individual based on the monitoring. In certain embodiments, the agent is a psychedelic agent. According to some embodiments, presenting a sensory environment to the individual comprises presenting to the individual a visual stimulus, an auditory stimulus, a tactile stimulus, an olfactory stimulus, or any combination thereof. In certain embodiments, presenting a modified sensory environment to the individual comprises presenting a customized sensory environment to the individual in real-time based on the monitoring. In some embodiments, the individual is suffering from a mental health condition selected from depression, anxiety, post-traumatic stress disorder (PTSD), addiction, and any combination thereof. Systems that find use in practicing the methods of the present disclosure are also provided.
