Thus, it is now known that OSA induces oxygen desaturation, arousals, and intrathoracic pressure changes which can result in sympathetic activation, endothelial dysfunction, hypercoagulability, systemic inflammation, oxidative stress, and metabolic dysregulation (Fig.
Among the 8,256 patients she reviewed, 6% fell into this group, with meaningful oxygen desaturation during more than 30% of their time asleep.
None of the patients had vomiting or oxygen desaturation (Table-2).
We found that the combined albuterol and budesonide nebulization decrease complications such as arterial oxygen desaturation (p<0.
This subset of patients might meet criteria for upper airway resistance syndrome, which was first described in 1993 and is characterized by repetitive increases in resistance to airflow, increased respiratory effort, absence of oxygen desaturation, brief sleep state changes or arousals, and daytime somnolence.
1] Such events include undersedation (with movement and possible injury), oversedation, oxygen desaturation, airway obstruction, laryngospasm, respiratory and cardiovascular depression or respiratory or cardiac arrest, seizures, unresponsiveness, allergic reactions, vomiting or excessive secretions, with risk of aspiration, and death.
Other risk factors for diabetes included AHI during rapid eye movement sleep and measures of the physiologic consequences of OSA, including oxygen desaturation, sleep deprivation and activation of the sympathetic nervous system, as indicated by a higher mean heart rate during sleep.
Our findings that prolonged oxygen desaturation, shorter sleep time and higher heart rate were associated with diabetes are consistent with the pathophysiological mechanisms thought to underlie the relationship between OSA and diabetes," he stated.
In addition, no studies have shown a benefit of long-term oxygen therapy when supplemental oxygen is prescribed for exercise-induced oxygen desaturation only.
The study evaluated oxygen desaturation rates among adults after a bunionectomy who were divided into three treatment groups.
No patient in rLMA group had oxygen desaturation less than 92% while it occurred in two (5.
