There is provided a method of detecting a fault in a breathing system. The method comprises the steps of (a) taking a series of measurements of a first parameter of the breathing system; and (b) setting a fault boundary for the first parameter, the fault boundary being dependent on a plurality of the measurements of the first parameter. The method further includes at least one update procedure comprising the steps of (c) taking one or more further measurements of the first parameter; and (d) updating the fault boundary, the updated fault boundary being dependent on an updated set of measurements of the first parameter, the updated set of measurements of the first parameter including at least one of the further measurements of the first parameter.

A method and an apparatus for dynamically adjusting a radio frequency parameter, and a radio frequency host are provided. The method includes: determining an operation stage of a radio frequency operation and acquiring a radio frequency data standard range and limit range corresponding to an operation object of the radio frequency operation at the operation stage; detecting radio frequency data of the operation object in real time; controlling the radio frequency data to be within the radio frequency data standard range by controlling an injection volume of a syringe pump to the operation object when the radio frequency data detected in real time exceeds the radio frequency data standard range but does not exceed the radio frequency data limit range and lasts for a preset duration; and stopping outputting radio frequency energy when the radio frequency data detected in real time exceeds the radio frequency data limit range.

Provided herein are compositions, methods, uses, and articles of manufacture for iodine treatment on mucosal membranes, and treatment of respiratory pathogens in this way—e.g., by inhalation and combined with the evaporation of steam. In certain embodiments, iodine treatment encompasses administration of compounds that release molecular iodine and/or physiologically active iodine-containing compounds.

Unwinding a portion of a support helix that comprises a heating wire from a wall of a hose at an end of the hose; sleeving a length of heatshrink tubing at least partly onto the unwound portion of the support helix; heating the heatshrink tubing to shrink onto at least part of the unwound portion of the support helix; and at an end of the unwound portion, directly connecting the heating wire to an electrical contact of an electrical connector.

A method and a system for determining the amount of oxygen required by a user with respiratory problems are disclosed. First data about several users with respiratory problems is stored in a database. The method a) collects second data from a monitored user while (s)he is performing a test at a first location; b) computes a user’s behavioral model executing a first algorithm on the first and second data; c) collects, every period of time t1, third data of the user while (s)he is performing an activity at a second location; d) adjusts, every period of time t2, the computed user’s behavioral model using the first algorithm, providing a customized user’s behavioral model as a result; and e) computes an estimator of the quantity of oxygen to be delivered to the user by executing a second algorithm on the customized user’s behavioral model.

Systems and methods are provided remotely controlling a medical device. In some embodiments, systems and methods are also provided for remote medical monitoring. This includes, for example, emergency/panic notifications/functions, medical event recording, compliance monitoring, sleep timer and environmental controls, two-way communication, and other functions such as, for example, emergency telephony/communication in various forms. In other embodiments, systems and methods for managing a remote control of a medical device are provided. This includes, for example, two-way communication for assisting in locating the remote, power management including sleep mode and wireless charging, and master remote/key functionality. The remote can be handheld or wearable and may include, for example, audio, visual, haptic, input, communication, and sensor (including biosensor) functionality and outputs. In this manner, the remote control can not only control the medical device, but also provides the user with extended functionality for emergency and non-emergency communication and tasks.

A drug overdose detection apparatus that is configured to measure the blood oxygen level of a user and upon detection in a drop thereof provide administration of a substance to counteract the drug overdose. The present invention includes a housing that is configured to be worn by a user has an interior volume. Disposed in the interior volume of the housing is a substance administration assembly wherein the substance administration assembly includes a syringe member, a plunger member and a plunger driver. A motor is operably coupled to the plunger driver and facilitates movement thereof. A spring needle assembly is operably coupled to the substance administration assembly and includes a spring biased needle that is operable to inject into a patient so as to inject the substance. The present invention further includes an audio alarm and transceiver configured to provide alerts and transmit signals.

A super enriched personal oxygen concentrator system that discards argon as waste, including a personal oxygen concentrator operatively attached to a first bed for absorbing nitrogen and second bed for absorbing oxygen, and an argon waste outlet operatively attached to the first and second beds for eliminating argon from the system. A method of using the system of the present invention, by absorbing nitrogen from compressed air from a POC with a first bed, absorbing oxygen with a second bed, discarding unabsorbed argon from the compressed air as waste, desorbing enriched oxygen product, and providing a 99% oxygen product. A fluid supply warning and communication system, wherein a primary fluid reservoir is connected to the personal oxygen concentrator system. A method of using the fluid supply warning and communication system.

A non-ventilator ET tube cap used to oxygenate a patient during an intubation procedure. The ET tube cap generally comprises an oxygen source connector configured to connect to an oxygen source via an oxygen tube. This provides oxygen to a patient via an ET tube while being intubated. The ET tube cap further includes an ET tube receiving aperture that is specifically arranged to engage an ET tube in a removable relationship prior to the ET tube connected to a ventilator while the ET tube is deployed in a patient. Optionally, the ET tube cap can comprise at least two pressure relief valves that open when pressure inside of the ET tube cap exceeds a predetermined pressure threshold to prevent harm to the patient that is being intubated.

An example medical system includes a hemodialysis device configured to receive blood from vasculature of a patient via an arterial line and to deliver blood to the vasculature of the patient via a venous line. The medical system includes a hematocrit sensor configured to generate a signal indicative of a hematocrit level of blood in at least one of the arterial line or the venous line. The medical system also includes processing circuitry configured to determine a change in blood volume of the patient over time based on the signal indicative of the hematocrit level, determine a threshold blood volume reduction over time for the patient, compare the change in the blood volume of the patient over time to the threshold blood volume reduction over time, and based on the comparison, generate an indication of vascular access recirculation.
