Term
| Why are arterial Blood Gas Analysis helpful? |
|
Definition
Act as an assessment tool to help understand the ptients acid/base balance, alveolar ventilation and oxygenation
Assesses whether oxygenation is adequate or abnormal |
|
|
Term
| Why is pH a good measure? |
|
Definition
| Bc is helps us understand how the body is doing in maintaining homeostasis (paraphrase) |

Term
What are the two main systems for pH management?
which system is the dominate system? |
|
Definition
Respiratory System: blows of CO2
Renal system (dominate system): H ions are excreted in the urine, also reabsorbed by bicarbonate into the blood |
|
|
Term
| What are the normal values for PaO2? |
|
Definition
80-100 mmHg
can have greater then 100 (this is not 100%) |
|
|
Term
| What are the pathological values for PaO2? |
|
Definition
Below 80 mmhg= hypoxemia
60-80 mild hypoxiemia
40-60 moderate
< 40 sever |
|
|
Term
| What is important about an elderly person and their PaO2 levels? |
|
Definition
| An elderly persons PaO2 levels typically run a little lower so if they dip down into the 70 or 80's not as much as a concern as with a younger individual |
|
|
Term
What are the approperiate ranges for:
PaO2
PaCO2
pH
HCO3 |
|
Definition
Pa02: 80-100
PaCO2: 35-45
pH: 7.35-7.45
HCO3: 22-28 mEq/liter |
|
|
Term
what is hypercarida
when does it occur
what it s similar term that means the same thing? |
|
Definition
hypercardia: when PCO2 > 50 mmHg
Hypercapina |
|
|
Term
| ABG are a very accurate picture of what the patient's ABG are only at the moment that the blood was draw? |
|
Definition
| Yes, ABG hemostasis is a very dynamic process |
|
|
Term
To determine if the patients pH change is due to primary respiratory process look at what value?
WHy is this? |
|
Definition
PaCO2
Bc pH and CO2 act inversely of one another (pH goes down by .10 when CO2 goes up by 20 mmHg) |
|
|
Term
A low pH and a high CO2 indicate what?
Why? |
|
Definition
Uncompensated respiratory acidosis
Bc as CO2 increase this drops the pH making the blood more acidic (i.e. there is more H in the blood not Co2?(mine)) |
|
|
Term
| A high pH and a low CO2 indicate what? |
|
Definition
Uncompensated Respiratory alkalosis
A low CO2 level in the blood means that there will be a higher pH |
|
|
Term
| What value do you look at to determine if the patients pH change is due to primary metabolic process? |
|
Definition
HCO3
pH and HCO3 change direct relationship, one goes up so does the other |
|
|
Term
| How do you determine if the patients primary respiratory process has been compensated for by the renal system? |
|
Definition
|
|
Term
A high HCO3 value in respiratory acidosis indicates what?
why?
|
|
Definition
Compensated respiratory acidosis
Bc a high HCO3 means that the HCO3 has to buffer CO2(H?) inorder to get the body back to hemostasis |
|
|
Term
| A low HCO3 value in respiratory alkalosis indicate? |
|
Definition
Indicates compensated respiratory alkalosis
bc do not want the biocarbonate to buffer CO2 (H) in order to lower the pH thus restoring Hemostasis
|
|
|
Term
| IN order to determine if the patients primary metabolic prcess has been compensated for by the respiratory system what value do you look at? |
|
Definition
|
|
Term
| What are the uses for flexiable bronchoscopy |
|
Definition
Dx
Theraputic
Sputum Analysis |
|
|
Term
| What does Oxyhemoglobin saturation indicate? |
|
Definition
Indication of pulomanry reserve, drive by the PO2 level in the blood
non-invasive SpO2 not SaO2 |
|
|
