The paradox of the StatCap carbon dioxide indicator. An experimental evaluation of rebreathing.
The StatCap semiquantitative carbon dioxide detector was evaluated in an experimental setting. The monitor underread at progressively higher concentrations of carbon dioxide. During simulated rebreathing, progressive increases in inspired carbon dioxide resulted in the StatCap readings decreasing. It is recommended that the StatCap be used with caution in circumstances where rebreathing may occur, for example, during manual ventilation with an Ayre's T-piece.
