Acceleration atelectasis causes a heavy cough, which F 22 pilots have called the cough after the nickname of the fighter, have complained about Nike Lebron 12 Data Review

In an e mail response to questions by Security Clearance, Air Force spokesman Lt. Col. John Dorrian said, testing has identified some vulnerability and reliability issues in the upper pressure garment worn by F 22 pilots. Air Combat Command has directed pilots to remove the upper pressure garment during routine flight operations, and Air Force officials are developing a fix to overcome the identified issues. findings in the update report to be given to Panetta are not final, according to the sources.
Investigators initially pointed to an onboard oxygen generating system that pilots used to breathe as a possible cause.
the cough in connection with the hypoxia like conditions as they fly the F 22, the most technologically advanced plane in history, often at altitudes much higher than regular aircraft fly. The pilots also perform maneuvers that put their bodies through extreme conditions.

The fleet was grounded in May 2011 so the service could check the hypoxia reports, but the order was lifted in September under a to fly plan, with equipment modifications and new rules including daily inspections of the life support systems.
The findings are expected to be part of the first monthly update by Air Force investigators to Secretary of Defense Leon Panetta to be delivered later this week or early next week, according to sources familiar with the investigation.
by Air Force investigators.
Investigators are focusing on part of the suit, called the Edge, which hampers breathing and causes oxygen loss when combined with a physiological condition that collapses air sacs in the lungs, according to details of the report that were shared with Security Clearance.
WASHINGTON (CNN) Air Force investigators believe a specialized flight suit could be partially responsible for some pilots experiencing a lack of oxygen while flying the F 22 fighter jet, according to a report Nike Kyrie Irving Bhm
Last month, Panetta mandated that all F 22 flights within the proximity of potential landing locations to ensure the ability to recover Nike Kyrie 2 Black and land should a pilot run into physiological conditions.
Lockheed Martin, the maker of the jet, was given a $19 million contract to install a backup oxygen system in the F 22 last week.
Last month, Panetta ordered the updates on the investigation after the Air Force could not identify the cause of the continued issues with pilots complaining about coming close to passing out while flying the plane, which the service called symptoms. Edge is a vest like garment that expands and contracts on a pilot torso to fight the effects of severe G forces experienced while flying the F 22. The problem being looked at is that the garment may restrict the pilots breathing beyond what is intended, according to sources familiar with the report.
Another possible problem for pilots, the report is expected to say, is a condition called acceleration atelectasis, which causes a pilot lungs to not effectively deliver oxygen to the bloodstream. The condition for F 22 pilots is caused when extreme gravity and breathing almost pure oxygen in the F 22 cockpit partially collapse air sacs in the lungs, according to the sources.
