The present invention relates to an integrated sleep diagnosis and treatment device, and more particularly to an integrated apnea diagnosis and treatment device. The present invention additionally relates to methods of sleep diagnosis and treatment. The sleep disorder treatment system of the present invention can use a diagnosis device to perform various forms of analysis to determine or diagnose a subject's sleeping disorder or symptoms of a subject's sleep disorder, and using this analysis or diagnosis can with or in some embodiments without human intervention treat the subject either physically or chemically to improve the sleeping disorder or the symptoms of the sleeping disorder. The diagnostic part of the system can use many different types of sensors and methods for diagnosing the severity of the symptoms of or the sleep disorder itself. The treatment part of the system can use a device to physically or chemically treat the subject's symptoms or sleep disorder itself.

The present disclosure relates to a system and method for use of acoustic reflectometry information in ventilation devices. The system and method includes a speaker to emit sound waves into an intubated endotracheal tube (“ETT”) and a microphone to detect returning acoustic reflections. In addition, the system and method includes a reflectometry device in communication with a ventilation device for analyzing timings and amplitudes of the returning acoustic reflections to determine a size of a passageway around an ETT tip, location and size of ETT obstructions, and relative movement of the ETT tip within a trachea. The reflectometry device is also configured to determine a resistance parameter representative of resistance to actual flow of air through the ETT based upon a function of the diameter of the ETT, length of the ETT, and percent obstruction of the ETT, where the resistance parameter is used to calculate the tracheal pressure.

A fluid distribution device comprises a disposable enclosure, and disposable fluid connectors connectable to compatible panel connectors of a control system. The fluid distribution device can also comprise, within the enclosure, a two manifolds connected to each other via a plurality of fluid interconnectors each being controllable by a valve system. One manifold can comprise a fluid inlet for receiving fluid from one of the panel connectors, and the other manifold can comprise a plurality of fluid distribution ports adapted for establishing fluid communications between the fluid interconnectors and fluid lines external to the fluid distribution device.

Systems and methods for novel ventilation that allows the ventilator to detect a patient intention to cycle exhalation are provided. Further, systems and methods for cycling exhalation based on a muscle pressure are provided.

This disclosure describes systems and methods for controlling pressure and/or flow during exhalation. The disclosure describes novel exhalation modes for ventilating a patient.

A method of controlling exhalation in a ventilation system for providing Positive Expiratory End Pressure, PEEP, ventilation to a lung is disclosed, the method comprising: determining a lung resistance based on conditions of the system detected during an exhalation; and causing the system to inhibit system exhalation to cause and maintain a target system pressure based on the determined lung resistance and a pressure condition in the system.

A medical breathing gas delivery system design employs a manifold delivering gas in a controlled fashion to patients which includes two inhaled gas one-way valves, at least one pressure sensor for patient airway pressure monitoring, and one controlled exhalation pressure proportional control valve which may be overridden by patient exhaled pressure or if there is a power loss. The manifold is connected to a controlled source of breathing gas which may, for example, be a variable-speed fan, or a pressure-based gas flow controller with dynamic self-calibration employing a fast-acting valve and a pressure sensor, either of which yield predictable gas flow control with a minimum of components. The manifold exhalation pressure control valve and gas flow source may, for example, be controlled with a computer system which adjusts the valve power waveforms to attain the time-varying flow and pressure curves required by clinicians, then stores and displays the waveforms to enable long-term trend monitoring and alarm generation. Accurate gas mixing using the pressure-based gas flow control yields automatically calibrated mixes which are of use for patients in, for example, intensive care ventilation and in anesthesia machines for operating rooms.
