| arterial carbon dioxide tensions during anaesthesia with manual ventilation. a descriptive study of the effects of various non-polluting circuits. | in 660 supine, intubated and anaesthetized, healthy patients scheduled for various elective surgical procedures, the distribution of arterial carbon dioxide tension (paco2) was investigated during manual non-monitored ventilation. the study comprised six equal groups: group 1: ventilation with a circle circuit absorber system; group 2: ventilation with the hafnia a circuit using a total fresh gas flow (fgf) of 100 ml . kg-1 . min-1; groups 3-6: ventilation with a hafnia d circuit with fresh gas ... | 1979 | 39415 |
| a simple method of monitoring carbon dioxide output in anaesthetized patients. | the mean co2 output during anaesthesia in paralyzed patients can be monitored by continuous capnographic analysis of the total exhaled gases, the latter being mechanically integrated by pumice canisters. the gas is evacuated from the hafnia a circuit via an ejector flowmeter. the results are not influenced by the flow rates employed. | 1977 | 143865 |
