A patient with pulmonary alveolar proteinosis underwent whole lung lavage of the right lung. Lavage of the left lung was not immediately possible because of severe hypoxemia. Three days later, after correction of hypoxemia, we re-attempted the left lung lavage. However, the patient had severe hypoxemia (SpO2 < 80%) within a few minutes of performing right one lung ventilation (OLV). On bronchos...
OBJECTIVE Hypoxemia, often assessed via pulse oximetry, is associated with neurocognitive deficits in children. The best way to qualify hypoxemia, or which level of hypoxemia already affects cognition, is unknown. METHODS We assessed the association of pulse oximetry-derived variables that qualify hypoxemia with impaired academic performance in mathematics in a population-based cross-section ...
Pulmonary gas exchange abnormalities and refractory hypoxemia cause myriad difficulties in patients with chronic liver disease. In addition to intrinsic cardiopulmonary diseases and hepatopulmonary syndrome, some unusual pathophysiological mechanisms in patients with portosystemic collaterals might contribute to hypoxemia. We report the clinical presentation of an unusual portosystemic anatomic...
BACKGROUND Perceived sleep quality may play an important role in diagnosis and therapy for obstructive sleep apnea (OSA). However, few studies have assessed factors that are associated with perceived sleep quality in OSA patients. Hypoxemia depresses the central nervous system and attenuates the perceived respiratory load in asthmatic patients. This study aimed to investigate the factors relate...
We studied the effects of 10-minute periods of hypoxemia in unanesthetized fetal lambs in utero instrumented for measurements of arterial pressure and renal and iliac blood flows. Fetal hypoxemia, induced by delivering a hypoxic gas mixture to the ewe, was characterized by a reduction in fetal PaO2 from 20.1 +/- 1.4 to 8.8 +/- 1.0 mm Hg (mean +/- SE). The fetus responded with bradycardia and pe...
Hypoxemia adds to the CURB-65 pneumonia severity score in hospitalized patients with mild pneumonia.
BACKGROUND Hypoxemia may influence the prognosis of patients with mild pneumonia, regardless of the initial CURB-65 score (confusion, blood urea nitrogen > 20 mg/dL, respiratory rate > 30 breaths/min, blood pressure < 90/60 mm Hg, and age ≥ 65 y). OBJECTIVE To determine the risk factors associated with hypoxemia and the influence of hypoxemia on clinical outcomes in hospitalized patients with...
We describe the effect of pregnancy on a woman with multiple pulmonary arteriovenous fistula. Pregnancy was terminated at 35 weeks' gestation because of severe hypoxemia. During the early postpartum period, the intrapulmonary shunt fraction enlarged, and hypoxemia worsened, necessitating emergency resection of the A-V fistula. Pregnancy may increase the intrapulmonary shunt fraction in patients...
