found that, in a relatively small study, 10 of 28 patients with TBI had sleep apnea and that the majority of these events were central apneas rather than obstructive apneas
The child continued to require oxygen support into the next postoperative day and was also noted to have obstructive apnea
and gasping by observation while asleep.
In mixed apnea, a period of central apnea is followed by a period of obstructive apnea
before regular breathing resumes.
Mixed apnea occurs when the sleeper experiences a brief period of central apnea normally followed by a longer period of obstructive apnea
Her brother Richard, 18, has a similar condition called obstructive apnea
, which forces his throat to close.
Episodes of central apnea, obstructive apnea
with hypopnea, as well as disturbances in the sleep/wake cycle, are most common.
The primary endpoint of the BREATHE study is the apnea-hypopnea index (AHI) at one month for two groups of patients: those diagnosed with central apnea (highly prevalent in heart failure) and those with obstructive apnea
Contributions of upper airway mechanics and control mechanisms to severity of obstructive apnea
Muscle sympathetic nerve traffic, which reflects peripheral sympathetic activity, is inhibited during the first phase of the obstructive apnea
, gradually increases during the second phase followed by a strong inhibition during the last phase.
All five suppressed obstructive apnea
, but none suppressed flow limitation.
Of the 27 obstructive apnea
episodes, I was associated with reflux.
Wetmore demonstrated that laryngeal instillation of acid causes obstructive apnea
secondary to laryngospasm.
