BACKGROUND Various portable monitors for identifying obstructive sleep apnea (OSA) have been investigated and reported to enable accurate recording of OSA severity. However, more information is needed from different populations. This study was conducted to evaluate the efficiency of a portable 2-channel sleep apnea device (SleepView) for screening OSA in the Chinese population. METHODS Ninety...

The increasing worldwide aquaculture output and concomitant decrease in the stocks of feedgrade fish used for fish oil production has made fish oil replacement in feeds a priority for the aquaculture industry. The regulation of fatty acid metabolism in fish is important in order to determine strategies for the best use of plant oils in diets for commercially important cultured fish species. We ...

OBJECTIVES In a video-based study of rapid sequence intubation (RSI) in a pediatric emergency department (PED), 33% of children experienced oxyhemoglobin desaturation (SpO2 < 90%). To inform targeted improvement interventions, we planned multivariable analyses to identify patient and process variables (including time-based data around performance of key RSI process elements uniquely available f...

OBJECTIVE To evaluate the effect of stochastic resonance (SR) stimulation on preterm infant oxygen desaturation, bradycardia, and apnea events. We hypothesized that SR stimulation will reduce these events. METHODS This was a randomized crossover study conducted from April 2012 to July 2014. Eligible preterm infants were not receiving ventilation support and had at least 1 clinically documente...

BACKGROUND Fiber-optic flexible bronchoscopy (FFB) is a frequently performed procedure for the diagnosis and treatment of pulmonary disorders. However, hypoxemia occasionally occurs during FFB. OBJECTIVES We attempted to examine the causes of arterial oxygen desaturation during FFB. METHODS We studied 336 patients who underwent FFB without intervention between June 1, 2001 and September 30,...

This prospective study evaluated the incidence and severity of arterial oxygen desaturation during esophagogastroduodenoscopy (EGD) and assessed clinical factors in relation to arterial oxygen desaturation. Following pulmonary function testing, 192 patients underwent elective EGD with continuous recording of arterial oxygen saturation (SaO2). 62 patients (32.3%) showed arterial oxygen desaturat...

Patients with chronic obstructive pulmonary disease (COPD) may benefit from ambulatory oxygen; however, the effect of exercise on arterial oxygen saturation (Sa,O2) in patients with kyphoscoliosis and of correction with ambulatory oxygen have not been previously reported. Twelve patients with stable kyphoscoliosis (mean (SD) Cobb angle 79 (26) degrees) were studied, with mean (SD) arterial oxyg...

BACKGROUND It is unknown whether cerebral oxygenation in patients with carotid artery stenosis (CAS) undergoing off-pump coronary artery bypass grafting (CABG) differs from that in patients without CAS. Thus, the effect of the presence of CAS ≥ 50 % on cerebral oxygenation during off-pump CABG in adult patients was evaluated retrospectively. METHODS Eleven patients with CAS ≥ 50% and 14 patie...

Uvulopalatopharyngoplasty (UPPP) is frequently employed in the treatment of obstructive sleep apnea (OSA). Despite anecdotal reports of early post-UPPP deaths and the recommendation by some authors to perform a prophylactic tracheotomy for selected patients at the time of UPPP, there has been no systematic examination of breathing during sleep in the early post-UPPP period. In order to evaluate...

STUDY OBJECTIVE Desaturation during intubation has been associated with serious complications, including dysrhythmias, hemodynamic decompensation, hypoxic brain injury, and cardiac arrest. We seek to determine the incidence and duration of oxygen desaturation during emergency department (ED) rapid sequence intubation. METHODS This study included adult rapid sequence intubation cases conducted...
