Narrative:

I was serving as a first officer in a flight between miami and maracaibo, venezuela. On the miami to maracaibo leg, one of our passenger became ill and was administered oxygen from 1 of the 5 portable bottles in the aircraft. When we arrived in maracaibo, venezuela, the captain, the flight engineer and myself checked the company MEL and determined that we were legal for the flight back to miami. Since our MEL calls for a minimum of 4 portable bottles and we had the 4 portable oxygen bottles on board. Our mistake was not to dmi the used (empty) portable oxygen bottle and write it on the aircraft logbook. It was an honest and innocent mistake on our part as a crew. We were briefed on arrival by company officials and we assure you it will not happen again.
