Assessment and treatment of respiratory fatigue

Objective Pulmonary Function (PF) evaluation for respiratory fatigue is vital to the diagnosis and management of many pediatric respiratory diseases in the intensive care, emergency and outpatient settings. A non-invasive PF instrument utilizes sensors and software to access respiratory breathing patterns, vital parameters, asynchrony and measures the work of breathing. Software algorithms predict respiratory fatigue. The hardware includes a microcircuit board that individually links to rib cage (RC) and abdominal (ABD) inductance bands. The bands wirelessly transmit changes in RC and ABD circumference. Point-of-care, real-time indices of respiratory work, breathing patterns and respiratory fatigue indices are developed on a user-friendly graphical user interface. The diagnostic data can later be securely emailed as an attachment for entry into patients' electronic medical records or sent to a caretaker's computer, or used directly to control a respiratory therapy device. The system can also be used for telemedicine homecare.

Fluorochemical liquid augmented cryosurgery

This invention is a method for cryogenic treatment of a lesion (20) which comprises the steps of delivering a fluoro-chemical liquid to the lesion (20), placing at least one cryoprobe (26) into the lesion (20), and circulating a cryogenic fluid causing an ice ball (30) to form in a vicinity around the cryoprobe (26), wherein the ice ball (30) obliterates at least a portion of the lesion (20). The fluoro-chemical liquid is utilized to augment the cryosurgical procedure and is perfused or injected into and/or around the lesion site prior and/or during the application of a cryprobe (26) to the site. In one embodiment of the invention, the fluoro-chemical liquid acts as a contrast agent to enhance real time medical imaging of the lesion area and modifies the environment in and around the lesion area. In another embodiment of the invention, the fluoro-chemical liquid augments cryosurgical procedures by controlling the size and shape of ice balls (30) formed during the cryosurgical procedures. In this embodiment, a fluoro-chemical liquid with a properly chosen thermal conductivity and freezing point is utilized.

Extrathoracic augmentation of the respiratory pump

Systems and methods for assisting respiration extrathoracically, particularly useful for augmenting respiration in neonatal patients, including providing a positive pressure to a torso area of a patient. The positive pressure may be delivered to the torso area of the patient while the torso area is exposed to an ambient pressure, such as by providing positive pressure with high frequency gas jets that are positioned in proximity to the torso area. The positive pressure may be delivered to different parts of the torso area of the patient at different times, such as by controlling gas jets independently. The positive pressure may also be controlled in coordination with a gas flow and concentration to the patient's airway, such as by increasing the positive pressure as a gas flow pressure delivered to the patient's airway is reduced. The gas flow to the patient's airway may be provided by, for example, a high-flow nasal cannula (HFNC) mechanism or a continuous positive airway pressure (CPAP) mechanism that is controlled in coordination with the positive pressure based upon a desired respiratory function of the patient. The control of the gas flow and the positive pressure may be based on an input of patient monitored parameters and/or calculated values based on the patient monitored parameters.

Breathable liquid elimination analysis

The amount of breathable liquid eliminated from a mammal through volatilization in the lungs and/or through skin transpiration is detected by measuring the amount of saturation of the expiratory gas by vapors or the breathable liquid. Instantaneous saturation values are employed to gauge the amount of interaction in the lungs between the breathable liquid and respiratory gas flowing therein and to control selected feedback operations to maintain the maximum possible amount of interaction therebetween. The saturation level of expiratory gas is also employed to optimize operating parameters or a system for recovering the breathable liquid from the expiratory gas, directly from the patient, or from a gas or liquid ventilator. The saturation level or expiratory gas is also employed to perform functional residual capacity studies and to correct for errors in conventional functional residual capacity measurements performed while a patient undergoes partial liquid ventilation. When breathable liquid is employed as a blood substitute, the quantification or the loss of the breathable liquid from volatilization and transpiration helps to determine when to replenish the breathable liquid in the bloodstream. Vapors of one form of breathable liquid, perfluorocarbon, are employed to determine the functional residual capacity of a mammal's lung.

Directionally controllable fishing lure

A directionally controllable fishing lure enables an angler to cast the lure to a desired area, with the lure traveling an arcuate path to the left or right upon retrieval. The direction of turn is determined by the angler, depending upon the rigging of the lure. The present lure has an elongate body with angularly truncated faces at each end thereof . The two faces are angled in opposite directions to one another, and the lure body is ballasted so that the two faces are always angled to one side when the lure is floating in the water, rather than facing upwardly or downwardly. The angularly truncated ends produce an asymmetrical hydrodynamic reaction as the lure is drawn through the water, causing the lure to turn in one direction or the other. If the angler attaches the fishing leader or line to the first end, the lure will travel in an arcuate path to the angler's right (or to the left, when considered in the direction of travel of the lure). Attaching the line or leader to the opposite end, results in a turn in the opposite direction. Thus, the present lure may be made to work around snags, weeds, and other obstructions, and/or may be made to work upstream in a current. The arcuate retrieve path is also much more realistic than the straight retrieval path of other lures, thus attracting fish more readily due to the realistic travel path of the present lure.

Thereafter, the emboli-containing liquid is removed from the patient or is used as an imaging agent. If gas emboli are not present, the site is imaged before the degassed liquid reaches atmospheric equilibrium. Thereafter, the liquid is removed from the patient. Moreover, by mixing a biological agent with the degassed PFC liquid, the mixture can be used as a way of topically treating parts within a patient's body cava. Furthermore, by regulating the temperature of the degassed liquid, it can also be used as a way of hypo- or hyperthermically treating the patient.

Treatment of physiological conditions with degassed perfluorocarbon liquid

This invention pertains to the use of a degassed perfluorocarbon ("PFC") liquid as a method of removing gas emboli from parts of a patient's internal anatomy. Moreover, the invention can be used as a method of imaging parts of a patient's internal anatomy. Furthermore, the invention can also be used as a way of delivering biological agents to parts of a patient's internal anatomy which contain or are surrounded by gas emboli and/or which are to be imaged. In this invention, a degassed PFC liquid is delivered to a region within the patient's internal anatomy which contains gas emboli and/or which is to be imaged. If gas emboli are present, the degassed liquid is permitted to absorb at least a portion of the emboli. Thereafter, the emboli-containing liquid is removed from the patient or is used as an imaging agent. If gas emboli are not present, the cite is imaged before the degassed liquid reaches atmospheric equilibrium. Thereafter, the liquid is removed from the patient. Moreover, by mixing a biological agent with the degassed PFC liquid, the mixture can be used as a way of topically treating parts within a patient's internal anatomy. Furthermore, by regulating the temperature of the degassed liquid, it can also be used as a way of hypo- or hyperthermically treating the patient.

Methods and devices for non-invasive cerebral and systemic cooling

Methods for cerebral cooling are described. Cooling assemblies include elongate tubular members, a reservoir containing a pressurized fluid, and a manifold connecting the reservoir and elongate tubular members. After insertion of the elongate tubular members into the patient's nostrils, a pressurized fluid is delivered onto a surface of the patient's nasal cavity through a plurality of ports in the elongate tubular members. The delivery of the fluid causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis.
