Monitoring General Anesthesia

This flashcard is focused on key terminology related to anesthesia monitoring, specifically highlighting the concept of Maintenance Level of Anesthesia.

detects temperature changes between cool inspired air and warmed expired air and beeps with each breath - no ETCO2 data

apnea monitor

where are apnea monitors places

between ET and breathing tube

what is 98% of oxygen in blood bound to

hemoglobin in red blood cells

how does a pulse ox work

the machine calculates SPO2 based on the difference between deoxygenated hemoglobin detected by red light and oxygenated hemoglobin detected by a blue light

pulse ox probe that transmits light through tissues - lingual, c clamp

transmission

pulse ox probe that reflects light off tissues - anus

reflectance

measures systolic blood pressure by inflating a cuff with a rubber bulb

sphygmomanometer

cat cuff size

30% of leg circumference

dog cuff size

50% of leg circumgerence

how much mmhg should you add to cat BP when using a doppler

15 mmhg

normal systolic BP range

80 - 120 mmhg

diastolic BP normal range

40 - 80 mmhg

mean arterial pressure normal range

60 - 100 mmhg

blood pressure measured by inserting a long catheter into the jugular vein and passed into anterior vena cava

central venous pressure

what is normal CVP

< 8 cm H2o

what is central venous pressure used to monitor

overhydration and right sided heart failure

normal etco2 values

35 - 45 mmhg

factors that determine blood co2 levels

rate of co2 production by cells, rate of transport to the lungs, rate of elimination from the lungs and the effectiveness of ventilation.
