[Industrial standards of hose assemblies for use with medical gas systems: safety against collapsing loads].
We experienced troubles caused by mounting an anesthesia machine and a pump oxygenator on an oxygen pressure-resistant hose that connected the central piping system with the anesthesia machine. Therefore, we measured the resistance of 9 types of hose assemblies to collapsing loads by the method in the International Standardization Organization (ISO) 5359. Two types of hose made in the U.S. were highly resistant. On the other hand, 7 types of domestic hose tended to be obstructed with collapsing loads, and 3 of them did not fulfill ISO's criteria. To prevent anesthetic accidents, improvements in the property of hose assemblies and the establishment of their industrial standardization are urgently needed.
