Q

Hypoventilation = decreased ____ & ____

A

RR & Tidal volume

137
Q

Causes of hypoventilation

A

Too deep
Obese patient
Tilted table
–Increase ventilations for all–may need to decrease gas

138
Q

Hyperventilation = ____.

Causes

A 
Increased RR
Too light-- increase gas 
Surgical stimulation
Pain-- analgesics 
Hypercapnia
139
Q

What is the most common causes of arrhythmias?

A

Hypoxia

Increase ventilations and turn down gas

140
Q

What are some signs that your patient is too light?

A 
Increased HR, RR, BP
Patient movement 
Palpebral
Eyes central
Tight jaw tone
141
Q

What should you do if your patient starts waking up?

A

Turn up vaporizer and ventilate & or give more induction IV drug

142
Q

What are some signs that your patient is too deep?

A 
Shallow respirations <8rpm 
Pale/cyanotic MM 
Increased CRT 
Bradycardia 
Weak/absent pulse
Hypotension 
All reflexes absent 
Slack muscle tone
143
Q

Doppler measures

A

Systolic BP and Pulse

144
Q

Oscillometric measures

A

Systolic, Diastolic, & MAP

145
Q

Normal systolic=
Normal diastolic=
Normal MAP=

A 
Systolic= 100-160mmHg
Diastolic= 60-100mmHg
MAP= 80-120mmHg
146
Q

Hypotensive systolic=

Hypotensive MAP=

A

Systolic= <60mmHg

147
Q

Causes of hypotension

A

Too deep– decrease gas
Drugs (vasodilation) –increase fluids
Blood loss– Dopamine, Dobutamine, Ephedrine

148
Q

Capnograph measures

A

ETCO2
Insp.CO2
RR

149
Q

ETCO2 should range between ____

InspCO2 should range between ____

A

35-45mmHg

0-5mmHg

150
Q

Decreased ETCO2 causes

A

Hyperventilation– increase depth or give more induction drug
Tube in esophagus– fix it!
Cardiopulmonary/Resp. arrest– ventilate/CPR

151
Q

Increased ETCO2 causes are usually due to ____. so you should ____.

A

respiratory depression causing hypoventilation

INCREASE VENTILATIONS!

152
Q

Increased ETCO2 can lead to ____.

Decreased ETCO2 can lead to ____.

A

Respiratory alkalosis

Respiratory acidosis

153
Q

If you have a increased InspCO2 you should ____

A

Check for expired soda lime granules (RB)

Increase O2 flow rate (NRB)

154
Q

Pulse Ox measures

A

O2 saturation of Hgb (% of Hgb saturated with O2)

Pulse

155
Q

Pulse Ox values should be around ____ under anesthesia because ____.

A

98-100%

They are breathing 100% oxygen

156
Q

Borderline hypoxia =

Cyanosis becomes apparent when O2 sat fall below __.

A

90-95%

Cyanosis apparent <85%

157
Q

Causes of decreased O2 sats.

A 
Probe problems 
Peripheral vasoconstriction 
ET tube placement/plug/kinked
O2 tank empty 
O2 flow rate too low 
Bradycardia 
VQ mismatch

Intervention= GET OXYGEN TO PATIENT!

158
Q

During the maintenance phase, monitor as many parameters as possible and turn down gas percents in ____ when at a good anesthetic level.

A

0.5% increments

159
Q

What could be wrong if your patient is not staying anesthetized?

A

ET tube not in trachea
Cuff may need to be inflated (gas can leak around)
Oxygen may be off or rate not high enough to carry gas
Vaporizer may need more liquid
Machine may be hooked up wrong
O2 flush valve being used too often (delivering 100% Oxygen)

160
Q

End of procedure steps:

A

Turn off vaporizer
Try to allow patient to breathe 100% O2 for up to 5min.
Disconnect patient from machine
Turn off oxygen
Be ready to deflate cuff on ET tube
Extubate after 2 good, successive swallows
Continue to monitor during recovery

161
Q

What is closely monitored during recovery?

A

Temperature
MM color/CRT
Pulse
RR
