|Table 3: Number of cats that achieved each anaesthetic plane for each end-tidal isoflurane (EtIso—%) concentration studied.|
|EtIso—%||Ocular reflexes||Attributed numerical scale||Number of cats that achieved the plane/total number of cats|
|PR−/CR−/EV or EC||3||2/10|
|PR−/CR−/EV or EC||3||8/10|
|2.0||PR−/CR−/EV or EC||3||10/10|
|A numerical scale was attributed from 1 to 3 according to the anaesthetic depth based on the presence (+) or absence (−) of ocular reflexes and the position of the eye: PR: palpebral reflex; CR: corneal reflex; EC: eyeball centred in the eye; EV: eyeball rotated ventrally.|
EtIso: end-tidal isoflurane concentration; numerical scale attributed according to the ocular reflexes observed.
