Pressurizing anesthesia machine
- Close the pop off valve
- Occlude the end of the rebreathing tube
- Press O2 flush valve
- Fill bad until manometer reads between 5-10 cm of H2O

Ayers-T non rebreathing bag is used for animals that weight what?
Less than 15 lbs
-
What does the Ayers-T non rebreathing system do for the animal?
Decreases the amount of "dead space" the animal has to move during inspiration and expiration
-
How to use the Ayers-T non rebreathing system

- Plug electrical plug into outlet
- Place sensor of choice in top of the machine
- Set highs and lows for pulse and SpO2
- Attach sensor to patient with red light facing the ceiling and turn machine on
- Pulse reading appears first, then SpO2
- Normal reading is 95-97, anything under 90 there is a problem
-
What does the doppler measure
Systolic pressure only
-
How to use the doppler machine
- Unplug the machine before use, make sure volume is all the way down
- Clip patient hair
- Put gel on probe with the side with 2 white lines
- Move slowly until artery is found
- Tape probe in place
- Place cuff above probe
- Inflate cuff until you no longer hear the artery
- Gently release cuff until you hear the first sound of blood flow back into artery
- This number is your systolic pressure
- Deflate cuff fully
- Gently clean probe and wires with alcohol
-
Surgivet placements
- Capnograph (clear short tube)
- Bottom hole: Purple cord NIBP
- Second hole: Temp, long black hose with white end (esophageal temp)
- 3rd hole: ECG
- Top hole: SPO2, black hose with clip sensor
