Resistance of Colorimetric Carbon Dioxide Detectors Commonly Utilized in Neonates.
BACKGROUND Colorimetric end-tidal carbon dioxide (ETCO2) detectors can identify airway obstruction during noninvasive ventilation and successful intubation during newborn resuscitation. The resistance of these devices is not well described, and the information provided by manufacturers is incomplete. METHODS We compared the resistance of 3 colorimetric ETCO2 detectors (Neo-StatCO2, Pedi-Cap, ...
متن کاملAmmonia and carbon dioxide concentrations in disposable and reusable ventilated mouse cages.
This study compares resuable and disposable individually ventilated mouse cages in terms of the formation of intracage CO2 and NH3. Crl:CD-1(ICR) female mice were placed in either disposable or reusable ventilated cages in a positive pressure animal rack. Intracage CO2 and NH3 were measured once daily for 9 d; temperature and relative humidity were monitored for the first 7 d. Results indicated...
متن کاملAversiveness of carbon dioxide.
Carbon dioxide can produce aversive stimulation of the upper airways, and in their recent review Conlee et al. (2005) emphasized: ‘y Leach et al. (2002) concluded that CO2, either alone or in combination with argon, cannot be used humanely at any concentration and is therefore unacceptable as a euthanasia agent for laboratory rodents, particularly when more humane methods exist. The findings of...
متن کاملAversiveness of carbon dioxide.
We are grateful to Dr Ronald Wood for providing in his letter in the July issue (Wood 2005) his expert views and methodologies that could potentially be used in future to test the behavioural effects of airborne contaminants and irritants. Dr Wood seems to accept in his letter that carbon dioxide is aversive but he is unsure how aversive, and believes that it can be safely and humanely used in ...
متن کاملCarbon dioxide - induced
Cockroaches (Periplaneta americana) learned to passively avoid electric shock in a two-compartment box after a single training trial. However, Ss exposed to CO2 gas immediately after the training trial failed to show retention of the previous experience when tested 24 h later. Results obtained are consistent with those observed in studies of retrograde amnesia in vertebrates. Article: Numerous ...
