Q

how is respiratory acidosis caused?

A

when you HYPOventilate
hypoxemia - low O2 (PaO2 less than 60%)

7.34 / 46 / 24 / 59

Q

what is the primary driver of ventilation?

A

HCO2- !!!!!!!

this means that you can hold air as long as you want but it will not effect % O2 saturation

But, this can be overcome by CNS during sedation

Q

what respiratory volume determines how long a person has until they desaturate their oxygen?

A

residual volume (how much air is left in the lungs after she has forced out as much as she can)

25
in zone 1 of the lungs, what are the partial pressures seen?
PA > Pa > Pv ``` A = alveolar a = atriole v = vein ```
26
in zone 2 of the lungs, what are the partial pressures seen?
Pa > PA > Pv ``` A = alveolar a = atriole v = vein ```
27
in zone 3 of the lungs, what are the partial pressures seen?
Pa > Pv >PA ``` A = alveolar a = atriole v = vein ```
28
what is hypoxic pulmonary vasoconstriciton?
helps to avoid shunt/ mix of oxygenated and deoxygenated blood *low alveolar O2 tension causes vasoconstriction
29
when pulse oximetry is employed, what should be audible to the anesthesia care team personell?
- variable pitch tone | - low threshold alarm
30
how should oxygen saturation continuously be evaluated?
pulse oximetry
31
what are the primary determinants of the O2 available for tissue metabolism?
- hemoglobin concentration - oxygen saturation of hemoglobin *this is bc dissoved O2 volume is negligible
32
what is the oxygen carrying capacity of hemoglobin?
-1.34 1 gram of hb can carry 1.34 mL of O2
33
On the O2 dissociation curve, what dec P50 (what inc affinity to hb)
dec temp dec Pco2 dec 2,3 - DPG inc pH
34
on the O2 dissociaiton curve, what inc p50 (what dec affinity to hb)
inc temp inc Pco2 Inc 2,3 - DPG dec pH
35
getting rid of CO2 gas
ventilation
36
what is the equation for minute ventilation?
RR (respiratory rate) x TV (tidal volume)
37
what is the normal minute ventilation?
5-6 L/min
38
when do we have respiratory alkylosis?
HYPERventilation
39
what is a precordial stethoscope used for?
to monitor breathing
40
according to the ADA, how should you monitor ventilation?
- observe chest excursions - "should" auscultate (stethascope) breath sounds OR monitor end-tidal CO2 *can also be measured by capnography
41
the process of moving air into and out of the lungs
ventilation *this is when CO2 is eliminated from the body
42
Using infared light absorption patterns to generate a wave that is displayed on a monitor to measure ventilation
capnography
43
what is the PaCO2 of the arterial blood
40 mmHg
44
what is phase 0 of ventilation?
inspiration
45
what is phase 1 of ventilation?
expiration begins, but CO2 free gas is expelled
46
what is phase 2 of ventilation?
mixing of the dead space gas and alveolar gas
47
what is phase 3 of ventilation
(expiratory plateau) as exhalation continues, remaining gas expelled is almost entirely alveolar
48
what drug can be given to inc RR?
Naloxone *same one they give to help heroin overdose
49
what is a sign that there is low blood flow going to tissues (poor perfusion) (reduced CO) (hypoventilation)
pallor
50
way of inflating to occlude artery and then slowly letting air out to measure the pressure coming through
ocillometry (blood pressure)
51
how do you calculate MAP?
2/3 diastolic + 1/3 systolic its all relatively unique and specific to each pt
52
what is the equation for BP
BP = SVR x CO
53
what does the P wave mean on an EKG?
-SA node in walls of the atria
54
what does the Q wave mean on an EKG?
impulse reached AV node which delays it by about .01 second
55
what does the RS wave mean on an EKG?
bundle branches carry signals from the AV node to the heart apex
56
what does the T wave mean on an EKG?
signal spreads through the ventricle walls
57
what does the ASA recommend for monitoring circulation?
every pt should have BP and HR evaluated and documented every 5 minutes *consider continuous EKG monitoring if the pt has significant CV disease
58
what is the average body temp in celcius?
37
59
why is it important to monitor for temp during sedation?
malignant hyperthermia
60
is measuring temp on the skin a good choice?
no bc heat is lost across epidermis
