A system including methods and apparatus for treatment of a medical disorder such as obstructive sleep apnea or congestive heart failure. The system involves applying separate and independent gains to flow rates of pressurized gas delivered to a patient during inspiratory and expiratory phases of a respiratory cycle to deliver the pressurized gas in proportion to the respective gains during inspiration and expiration. A base pressure may be applied in addition to the gain-modified pressures and an elevated pressure profile may be employed to assist or control inspiration. The system may be fully automated responsive to feedback provided by a flow sensor that determines the estimated patient flow rate. A leak computer can be included to instantaneously calculate gas leakage from the system. The system may be utilized in connection with conventional continuous positive airway pressure (bi-level PAP) equipment to effect various beneficial treatment applications.

A task management system uses patient tags (e.g., wireless RFID, Infrared tracking, GPS etc.) for patient location tracking, together with an integrated workflow system to automatically, track patient location how long they have been there and how many patients are at the same location (e.g., waiting room) and manages waiting time and an overall waiting queue, supporting automated adjustment of healthcare staffing, patient flows, and team coordination. A task management system for use in providing healthcare to a patient includes a patient tracking processor and a workflow processor. The patient tracking processor automatically acquires data derived by wireless communication from patient attached tag devices for use in identifying a location of multiple patients in a healthcare enterprise and identifying a first number of patients at a particular location and a second number of patients awaiting receiving a particular type of treatment. The workflow processor automatically initiates a patient load balancing activity to improve a match between a healthcare resource and a patient load by communicating a message to update a healthcare worker task schedule with a task in response to a determination the identified first or second number of patients exceeds a predetermined threshold number.

The patient-centric eco-system operates in healthcare facility's (HC-FAC) treatment/recovery/waiting rooms using audio/visual (presence) sensors and image sensors (serial static images or video). Sensors capture patient presence sensory data in rooms. Computing devices process data and obtain room-to-room patient unique transition data, patient unique treatment/recovery timing data, and treatment/recovery image data. System digitally tags and segments the treatment/recovery images (serial static images or video) to generate time-stamped patient unique treatment/recovery image data which is serial static images or video clip(s). Patient/provider replay command displays processed images or video clip. The display may be on a multimedia medical documentation presentation platform. To monitor and track patient flow through HC-FAC, a basic process flow user interface (UI) is a 3-column display (arrivals, treatment/recovery and check-out) tracking all patients at the HC-FAC with patient-display tiles manual/auto moved column-to-column as each patient transitions through HC-FAC.

A disposable outlet patient flow line for in-line blood/fluid warmer devices uses both passive insulation and active warming to deliver normothermic intravenous fluid to the patient connection site at very low flow rates. A co-extruded annular air space provides passive insulation which reduces heat loss to the cooler ambient air, but by itself this is inadequate for flow rates less than about 15 milliliters per minute. Temperature controlled heating elements located inside the annular air space replace heat lost to ambient air outside the flow line, maintaining the annular air space at about 42 degrees C., thus preventing heat loss from the central blood/fluid carrying lumen. Normothermic fluid is delivered to the patient at body temperature down to essentially zero flow-rate, using a low cost, convenient disposable outlet patient flow line.
