Q

What route if IV sedation?

A

-Parenteral

17
Q

What is an advantage of IV sedation?

A
  • Direct to blood 22-122 seconds for hypnotic
  • Rapid onset of action
  • Can titrate effect rapidly
  • Control duration of sedation
  • Have access for emergent therapy
18
Q

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

A

-2-3 personnel

19
Q

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

A

-6 hours

20
Q

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

A

-2 hours

21
Q

Why should you use a capnography?

A

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

22
Q

When is a temperature recording mandated?

A

-Only during deep sedation

23
Q

What does a pulse oximeter measure?

A
  • Arterial oxygen saturation of hemoglobin

- ratio of oxygenated Hb and total Hb

24
Q

All types of IV sedation should have what monitoring?

A
  • Blood pressure monitoring
  • Pulse oximeter
  • ECG
  • Pre-coridal stethoscope
  • Capnography
  • Temperature recording
  • Time based record at least 5 minutes apart
25
Q

What can be sources of error for pulse oximetry readings?

A
  • Body movements
  • Dyshemoglobeinemias
  • Lipids and bilirubin
  • Color interferences: nail polish
  • Venous pulsations
  • Physical factors
26
Q

What does Capnography measure?

A

-The amount of carbon dioxide in the expired gases

27
Q

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

A

True

28
Q

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

A

True
