29
definition of SPO2
Saturation of Peripheral Capillary oxygenation.
Pulse oximetry measures oxygen saturation levels.
30
definition of ETCO2
measures ventilation status. Is the CO2 in the
airway at the end of exhalation.
31
what is the respiratory cycle in ETCO2
ventilation + circulation + metabolism = gas exchange
32
what is dead air space
ventilated areas that do not participate in gas exchange
33
why capnography?
because respirations, ventilations and oxygenation are very different concepts
34
what is capnography
- Represents the amount of CO2 in exhaled air
-The number- “Capnometry”- partial pressure of
CO2 at the end of exhalation
35
how is ETCO2 measured
- pt who are breathing: nasal prongs
-pt with assisted ventilations: device attached to BVM
36
pt respiratory rate when Co2 is increased
should increase
37
pt respiratory rate when Co2 is decreased
should decrease
38
how do we assess ventilations
-chest rise and fall
-respiratory efforts
-auscultation
-respiratory rate
39
why is capnography important
verification of proper tube placement. no waveform = no tube
40
quantitative waveform
an actual numeric value associated with an electronic device: 35-45mmhg
41
Qualitative waveform
low/medium/high value- give range vs actually number. colorimetric device is an example
42
phase 1
(A-B) inspiratory baseline (low CO2 a its inspired air)
43
what is PaCo2
Partial Pressure of Carbon Dioxide in arterial blood
gases. The PaCO2 is measured by drawing the
ABGs, which also measure the arterial PH
-normal is 35-45 mmhg
44
What is B in waveform
the start of alveolar exhalation
45
phase 2
(B-C) exhalation upstroke (dead space gas mixes with lung gas)
46
phase 3
(C-D) continuation of exhalation (gas is all alveolar now, rich in CO2)
47
what is D in waveform
the end tidal value, peak concentration
48
phase 4
(0)(D-E) start of inspiration
49
sudden loss of waveform
-ET tube disconnected, dislodged kinked, or obstructed
50
decreasing ETCO2
-et tube cuff leak
-ET tube in hypo pharynx
-partial obstruction
51
cpr assessment
attempt to maintain minimum of 10mmhg
52
sudden increase in ETCO2
ROSC
52
bronchospasm
-sharkfin appearance
-asthma or COPD
53
hypoventilation
long flat waveforms
54
hyperventilation
quick small waveforms
54
decreased etco2
apnea or sedation
55
why the slope in etco2 with bronchospasm?
Because the movement of air at the alveoli is
delayed in a person with bronchospasm, the rise
to the plateau is more gradual and the plateau
itself becomes sloped
56
hyperventilation-low co2
they are blowing off large amounts due to the increased RR
57
what causes hyperventilation
anxiety, bronchospasm, pulmonary embolus
57
what causes low etco2
cardiac arrest, hypotension, decreased cardiac output, cold
58
hypoventilation-high co2
they are retaining CO2 due to slowed RR
59
what causes hypoventilation
overdose, sedation, intoxication, postictal states, head trauma, stroke, tiring CHF, fever, sepsis, SOB
60
when cardiac output is normal...
ETCO2 measures ventilation
61
when cardiac output is decreased...
ETCO2 measures cardiac output
62
what does it mean when cardiac output fails
very little metabolism takes place and very little blood flows through the lungs, resulting in little perfusion and gas exchange; ie cardiac arrest
63
ETCO2 in a cardiac arrest
cardiac arrest is the ultimate shock state, there is no metabolism and no CO2 production unless CPR is being done
64
ETCO2 of <10mmhg indicates...
compressions are not deep or fast enough
or
pt will not survive
65
spike in ETCO2 meaning
circulation is restored, even if you can't feel a pulse, circulation must be present
66
why is there a low survival rate with low ETCO2
If a relatively high ETCO2 can be accomplished by
good CPR- it can be assumed that cardiac output
is high enough to support a successful
resuscitation
-If a patient has been VSA for a long time,
vasodilation and sluggish blood flow prevents the
build up of significant cardiac output despite good
CPR
67
why the sudden spike in ETCO2 for a ROSC
- Large amounts of acidic blood are suddenly returned to the lungs and high amounts of CO2 diffuses into the alveoli
- This flood of CO2 causes a remarkable sharp rise in the ETCO2 levels to much higher then normal
68
what are sudden spikes in ETCO2 considered
signs of life, complete a pulse check and reassessment
69
what is the tidal volume?
amount of air that a patient takes in (goes in) during one breath

78
colloids description
contain large molecules such as PROTEINS
- example: plasma substitutes, packed RBC and while blood, plasmanate, dextran, hetastarch
79
colloids action
do not pass through the capillary membrane as readily as colloids
80
hypotonic
lower solute in the solution then the cell, causes water to go into the cell
81
hypotonic example
NS,LR
82
hypertonic
higher solute in the solution causes water to leave the cell
83
hypertonic example
mannitol
84

5. Each bag contains enough solution to: Flush the administration set – good for 24 hours, allow for accurate readings of volume even with sterile air in the bag
86
priming an IV bag steps
1. Select the appropriate IV tubing. Inspect the tubing, the roller clamp, the injection
ports & the luer lock connector for cracks, use and sterility.
2. Select the appropriate sized IV bag. Inspect for cloudiness, precipitate and cracks/leakage. Check the expiry date, and ensure the fluid is the proper type (Normal
Saline or 0.9% saline).
3. Close the roller clamp.
4. Remove the cap on the IV tubing closest to the drip chamber. Ensure sterility! Remove
the plastic tab on the IV bag. Connect the two.
5. Squeeze the drip chamber. Fill it ½ full.
6. Open the roller clamp slightly to advance the fluid down the tubing.
7. When the fluid approaches an injection point, invert the port and strike the port, forcing air out and fluid in. Repeat as many times as needed.
8. Close the roller clamp when all the air is expelled from the tubing.

- Airway obstruction
102
king LT insertion
elect the appropriate size tube, based on the patient's height:
* Size 3: 4 to 5 ft (122-155 cm)
* Size 4: 5 to 6 ft (155-180 cm)
* Size 5: > than 6 ft (180 cm)
* Apply lubricant to the beveled distal tip and posterior aspect of the tube, taking care to avoid introduction
of lubricant in or near the ventilatory openings.
* Pre-oxygenate via BVM.
* Position the head. The ideal head position for insertion of the KING LTS-D is the “sniffing position”.
However, the angle and shortness of the tube also allows it to be inserted with the head in a neutral
position. For obese patients, elevation of the shoulders and upper back should be considered.
* Hold the KING LTS-D at the connector with dominant hand.With non-dominant hand, perform a tongue-
jaw lift and insert tube into corner of mouth.
* With the KING LTS-D rotated laterally 45-90 degrees, such that the blue orientation line is touching the
corner of the mouth. Introduce tip into mouth and advance behind base of tongue.
* As tube tip passes under tongue, rotate tube back to midline (blue orientation line faces chin).
* Without exerting force, advance tube until base of connector is aligned with teeth or gums.
* Advance the device until the lips are rest between the black bands on the dev
103
pathophysiology of asthma: bronchoconstriction
smooth muscle contraction narrows the airway
103
igel insertion
1. Remove i-get from protective cradle or pack
2. Grasp lubricated I-Gel firmly along the integral bite block. Position device so
the cuff outlet is facing towards patient’s chin.
3. Gently press down on chin to open mouth (no fingers or thumbs in mouth).
4. Introduce leading soft tip into pt’s mouth in a direction towards hard palate.
5. Glide the device downwards and backwards along the hard palate with a
continuous but gentle push until definitive resistance is felt. Sometimes a feel
of ‘give-way’ is felt before end point resistance is met. This is the due to the
passage of the I-Gel bowl through the faucial pillars. Continue to insert device
until definitive resistance is felt.
103
when do we remove a SGA in a rosc
- only if gag reflex is stimulated, or patient begins to vomit
104
complications of IGEL
