title: An easily assembled and inexpensive apparatus for continuous monitoring of expired carbon dioxide concentrations in artificially ventilated animals.
abstract: An inexpensive and simple apparatus for monitoring expired carbon dioxide concentrations in artificially ventilated animal preparations is described. The system may be rapidly and easily constructed using a standard recording pH electrometer and a commercially available Pco2 electrode. This assembly has been proven to be an effective and sensitive means of monitoring CO2 levels, detecting changes in this gas within one-half percentage.
