17

What is an advantage of IV sedation?

-Rapid onset of action
-Can titrate effect rapidly
-Control duration of sedation
-Have access for emergent therapy

18

If you do IV sedation how many people have to be in the room with you?

-2-3 personnel

19

How long before surgery should a person not eat food or fluid prior to surgery?

-6 hours

20

Clear fluid intake should not be taken within how soon of surgery?

-2 hours

21

Why should you use a capnography?

Because it can identify apnea or airway compromise much earlier than pulse oximetry

22

When is a temperature recording mandated?

-Only during deep sedation

23

What does a pulse oximeter measure?

-Arterial oxygen saturation of hemoglobin
-ratio of oxygenated Hb and total Hb

24

All types of IV sedation should have what monitoring?

-Blood pressure monitoring
-Pulse oximeter
-ECG
-Pre-coridal stethoscope
-Capnography
-Temperature recording
-Time based record at least 5 minutes apart

25

What can be sources of error for pulse oximetry readings?

-Body movements
-Dyshemoglobeinemias
-Lipids and bilirubin
-Color interferences: nail polish
-Venous pulsations
-Physical factors

26

What does Capnography measure?

-The amount of carbon dioxide in the expired gases

27

T/F It is now mandated that anyone who does IV sedation whether conscious, deep, or general has to have a capnography.

True

28

T/F Increases in end tidal CO2 measured through a capnograph precede the decrease in oxygen saturation measured by pulse oximetry.

True
