Table 2. Respiratory rate, blood gas values and arterial pH (mean ± SD) in 5 horses on IPPV undergoing carotid artery translocation via KMP-TIVA.
| Variable | Pre value | Before skin incision | 30 min | 60 min | Ope-end |
|---|---|---|---|---|---|
| RR (breaths/min) | 15 ± 3 | 6 ± 0 | 6 ± 0 | 6 ± 0 | 6 ± 0 |
| pHa | ND | 7.45 ± 0.04 | 7.46 ± 0.04 | 7.47 ± 0.04 | 7.48 ± 0.05 |
| PaCO2 (mmHg) | ND | 54 ± 5 | 51 ± 7 | 51 ± 7 | 49 ± 6 |
| PaO2 (mmHg) | ND | 598 ± 127 | 581 ± 115 | 589 ± 109 | 617 ± 111 |
Data showed mean ± standard deviation from 5 horses. Pre value was measured before any medications were administered. ND: Not determined. Before skin incision: Just before skin incision, 30 min: 30 min into surgery, 60 min: 60 min into surgery, Ope-end: At the end of operation. RR: Respiratory rate, pHa: Arterial blood pH, PaCO2: Partial pressure of arterial carbon dioxide. PaO2: Partial pressure of arterial oxygen.
