To compare pH and PCO2 values of simultaneously obtained arterial, arterialized capillary, and venous blood samples and also to compare oxygen saturation (ASaO2) measured in arterial blood and oxygen saturation by pulse oximetry (PSaO2). ⋯ Even though arterial blood gas analysis is the gold standard, and when an arterial blood gas sample cannot be obtained, a combination of arterialized capillary blood gas and pulse oximetry can be effectively used in acutely ill children of all ages. Venous samples have a good correlation with arterial samples for pH but are not useful for monitoring blood gas status in acutely ill children.

[corrected] Foreign body inhalation is an extremely serious problem in children and sometimes result in sudden death. The current mortality rate from foreign body inhalation is between 0% and 1.8% according to various studies. In spite of this, undiagnosed and unsuspected foreign bodies still occur in the airway. ⋯ Tracheobronchial foreign bodies should be strongly suspected in pediatric age group who present with a suggestive history, even when physical and radiographic evidence is absent. The modalities of diagnosis, management and outcome are discussed.
