Non-invasive ventilation for the treatment of acute respiratory failure following ovarian hyperstimulation syndrome: report of two cases and a brief review of the literature.

The ovarian hyperstimulation syndrome (OHSS) is a serious but rarely fatal complication of medical interventions that seek to induce fertility; it is typically encountered in women who undergo controlled ovarian hyperstimulation, but there are very rare patients who have genetic defects who present with OHSS. In recent years, its pathogenesis has been elucidated; this knowledge will decrease the frequency of this syndrome. Clinical signs may include any or all of the following: rapid weight gain, ascites, oliguria, hemoconcentration, leukocytosis, along with intravascular hypovolemia, hyponatremia, and hyperkalemia.

Disability in COPD and its relationship to clinical and patient-reported outcomes.
