Title: [abstract] SEQUENCED, HEMOGLOBIN BASED ARTIFICIAL GILLS SYNTHETIC GILL SUPPORTS DIVER'S OR CLIMBER'S BREATHING BY CONCENTRATING O2 FROM SEAWATER OR FROM THIN AIR AT ALTITUDE, AND VENTING CO2
Author: Lande' AJ
Abstract: BACKGROUND: Hemoglobin ordinarily absorbs, transports and delivers O2 from lungs or gills to tissues and CO2 is transported in the opposite direction, as described by the Bohr equations.MATERIALS AND METHODS: This presentation proposes for discussion the thesis that hemoglobin or prospective hemoglobin-like liquids might also be utilized to concentrate and store the sparse oxygen in seawater, or in air at altitude, sufficiently to support an active diver or climber.RESULTS: Several (approx.4) sequenced, diminishing area membrane oxygenator-like artificial gills , connected by (approx.3) distinct, two-artificial gills, decreasing volume, increasing hemoglobin circuits, compose a synthetic gill . Hemoglobin bound O2 will be released close to the acidified sides of the membranes, across from the alkalinized and thus desaturated increasingly greater concentrations of hemoglobin on the opposite sides, resulting in passive transport through the excellent state of the art, or prospective future nanoengineered, membranes. A great volume of seawater or thin air must pass close alongside the largest membrane. A small volume of rebreathed gas is routed close to the smallest membrane. Oxygen concentration is expected to result. At normal human hematocrits, hemoglobin can store approx.70x more oxygen than can plasma. Higher concentrations of free, saturated hemoglobin in the several circuits could store even more, providing an O2 backup for brief emergencies.CONCLUSIONS: Means are proposed for man's breathing underwater like a fish, which, similar to flying like a bird (Burt Rutan) has been dreamed of since Daedalus and Icarus.
