An 80 percent reduction in oxygen desaturation events from baseline
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.
To assess the apnea-hypopnea index (AHI), the researchers defined disordered-breathing events based on both the >3% and >4% thresholds for oxygen desaturation.
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.
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.
In addition, no studies have shown a benefit of long-term oxygen therapy when supplemental oxygen is prescribed for exercise-induced oxygen desaturation only.
Regional oximetry-monitored procedures typically allow for early indication of oxygen desaturation that could lead to stroke, neurocognitive decline and other neurological or major organ injuries resulting from inadequate oxygen saturation.
Median duration of hypercarbic, hypoxic, and tachycardic events in 39 patients after cardiac surgery based on transcutaneous carbon dioxide monitoring in the intensive care unit Event Number Median of total patients duration with at (minutes) least one event Mild hypercarbia (42-49 mm Hg) 35 303 Moderate hypercarbia (50-59 mm Hg) 26 67 Severe hypercarbia ([greater than 15 13 or equal to]60 mm Hg) Severe oxygen desaturation 31 1.
1]/FVC% predicted, distance walked in the 6MWT, and oxygen desaturation during 6MWT.
She was initially admitted to the pediatric ward, but 1 hour after admission, she required transfer to the intensive care unit (ICU) for increasing stridor and oxygen desaturation to the 70 to 80% range.
Patients with untreated moderate to severe OSA, defined as an apnea/hypopnea index (AHI) [greater than or equal to] 15 events/h and arterial oxygen desaturation to <90% at least once per night on the polysomnographic study, were included in the study.
Published data on IV PCA side-effect profiles suggests that somnolence (~50% of patients) and oxygen desaturation (~10% of patients) is unacceptably high.
