Embodiment Construction

[0063] In some embodiments of the present invention, the present invention relates to fluid measurement in vivo, and more particularly, but not exclusively, to systems and methods for sensing lung fluid of a patient.

[0064] As used herein, the term "pulmonary fluid" refers to pleural effusion and / or pulmonary edema. The term "lung fluid" may refer to one or more types of lung fluid, such as various types of transudates and / or transudates and blood.

[0065] As used herein, feeding tube is sometimes used interchangeably with the term nasogastric tube. For example: a nasogastric tube (ie, used to remove fluid from the stomach and / or digestive system) may be used instead of a feeding tube (ie, used to deliver enteral food to the stomach and / or digestive system). It should be noted that in some cases a dedicated catheter may be used to monitor lung fluid.

[0066] An aspect of some embodiments of the invention relates to a system, a method, an apparatus, and / or code instructions...

Abstract

An apparatus for monitoring for accumulation of lung fluid comprises a feeding tube having first electrode(s) positioned thereon for electrical contact with tissue of an esophagus of a target patient including a lower esophageal sphincter (LES) and / or tissue in proximity to the LES, second electrode(s) sized and shaped for contacting skin of the target patient, and a non-transitory memory having stored thereon code instructions for applying alternating current(s) to pair(s) of first and second electrodes, measuring a voltage over the pair(s), and computing an estimate of a change of lung fluid relative to a baseline in lung(s) of the target patient according to the applied alternating current and measured voltage, wherein applying the at least one alternating current, measuring the voltage and computing the estimate of the change in lung fluid are iteratively executed for monitoring the target patient for accumulation of lung fluid while the feeding tube is in use.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 430378, filed December 06, 2016, which is incorporated herein by reference in its entirety. technical field [0003] In some embodiments of the present invention, the present invention relates to fluid measurement in vivo, and more particularly, but not exclusively, to systems and methods for sensing lung fluid of a patient. Background technique [0004] A pleural effusion is an accumulation of fluid outside the lungs, in the pleural space of the lungs. Pulmonary edema is the accumulation of fluid in the lungs, in the alveoli and / or the lung parenchyma. Pleural effusion and / or pulmonary edema may be present in patients, eg, admitted to an intensive care unit, eg due to desaturation of oxygen. [0005] Pleural effusion and pulmonary edema share some aspects of pathophysiology, eg, pathophysiology caused by heart failure, fluid volume overlo...
