Question 1

Your anesthetic patient, Gretchen, is a 4-year-old, 66 pound (30 kg) female spayed mixed breed
dog, presented for a dental cleaning. She is intubated and receiving inhalation anesthetic and
oxygen through a partial rebreathing system. She is showing the following parameters. She is
unconscious and immobile. Her respirations are regular, shallow and the rate is normal. She
receives an assisted ventilations every 5 minutes. Her heart rate and pulse strength are decreased.
Her mucous membrane color and CRT are normal.
