The National Transportation Safety Board recommended that the FRA require all railroads to screen for and treat sleep apnea more than a decade ago, after a 2001 accident in Michigan, however, some rail lines have yet to perform a single sleep apnea test
For most people suspected to have obstructive sleep apnea who are otherwise healthy, a home sleep apnea test
can be a first-line option to distinguish obstructive sleep apnea from snoring alone.
In summary, the criteria of the United States consist of four steps: (1) Prerequisites: definite and irreversible coma whose cause should be excluded drug, hypothermia, alcohol, and other laboratory abnormal values; (2) examination: absence of brainstem reflexes; (3) the apnea test
result is positive; and (4) ancillary tests can be used when uncertain about the clinical examination or when the apnea test
cannot be performed.
Results: The current hospital policy lacked two important components of any BD policy: (a) the apnea test
techniques and (b) guidance regarding secondary confirmatory testing.
The subjects were instructed to lie down in the supine position for a 5-min rest period before completing the dry static apnea test
as previously described (11).
Finally, in what's called the apnea test
, the ventilator is disconnected to see if you can breathe unassisted.
The doctor said the final test done before the boy was declared brain dead, an apnea test
, had doctors remove the ventilator helping Nathaniel breathe.
sup] In summary, the criteria of the BD diagnoses consist of four steps: (1) The clinical examination confirm the BD diagnose, including deep coma, absence of brainstem reflexes, and no spontaneous respiration; (2) confirmatory tests should fulfill two of the three which include transcranial Doppler (TCD), electroencephalogram (EEG), and somatosensory evoked potential; (3) the apnea test
is positive; and (4) a repeat determination should be done 12 h after the first time.
The apnea test
is intended to determine the patient's ability/inability to breathe unaided.
