COMPS: Pulmonary Dx Tests/Procedures: Exam 1 Flashcards
pH
Normal Value vs. Normal Range
- Normal value ==== 7.40
- Normal range===7.35-7.45
Metabolic Acidosis
*Diabetic Ketoacidosis
Respiratory Alkalosis
- PaCO2<35; DEC PaCO2= DEC pH
- hypERventilation
- tachycardia
- hypOkalemia
INvasive Pulm tests
bronchoscopy
Arterial blood gas analysis (ABG)
Cytological tests
PFF table
Normal
Restrictive
Obstructive
see pics
Hematological tests aid in assess. of what?
CP disease
Lung Diseases: 2 types
- Restrictive
- Obstructive
Hematological tests:
Anemia
LOW Hb
LOW RBC
LOW Hematocrit
*immune response
These are indicated to rule OUT PE
V/Q scans
V/Q scans
- Xenon gas used to measure regional distribution of ventilation in lungs
- pt inhales gas and holds breath while ventilation scans are made over lung field
FEV1/FVC=====
Air OUT 1sec/Air OUT entire time
Cytological Tests are checking for:
Bacteria
Fungi
Protozoa
Viruses
Flow-volume graph/loop
Normal
Restrictive
Obstructive
see pics
HCO3-
- KIDNEY BASED
- metabolic
- Bicarb is a BASE
- makes blood more BASIC!!!
Advantages vs. Disadvantages
Chest CT vs. Chest radiography (xray)
see pics
ABG
clinical notes:
ABGs are…..
time dependent
Pulmonary Function Test
all volumes and capacities
see pics
V/Q scans described by:
Neg.
Low Prob of PE
Intermed. Prob of PE
High Prob of PE
Abnormal ABG:
Acidosis
pH>7.35
PCO2> 45
HCO3- <22
What should you remember about “Capacities”
HAS TO BE MORE THAN ONE VOLUME ALWAYS
Normal Chest radiographs
see pics
What views taken for chest xray?
what do we WANT to see?
- 2 views:
- PA
- L. Lat.
-
we want to see BLACK
- ==> Air in lungs
Abnormal ABG
Alkalosis
pH >7.45
PCO2 <35
HCO3- >26
Hematological tests:
Leukopenia
DEC WBC
Blood Gas Analysis/ABGs
Crucial to assess probs related to what?
Acid-base balance, ventilation, oxygenation
VC vs. FVC
SAME THING
FVC is 6secs
PaO2
NORMAL
80-100
Hematological tests:
Anemia
Polycythemia
Leukocytosis
Leukopenia
ALL ARE WHAT?
IMMUNE RESPONSES
Typical Hematological Tests include:
- ABGs
- electrolytes
- CBC’s
- coagulation studies
Residual volume
NO participation in gas exchange
air we cannot use
Total Lung Capacity
TLC ====
ALL air in lungs
EVERYTHING added together
~5L
%SAT should be
> 95%
Range of PaCO2
35-45
Chest imaging
chest radiograph
MOST COMMONLY USED DX TEST
where is pt placed?
pt placed b/w x-ray machine & cassette
PaO2
<80
- hypoxemia
- mild= 60-80
- mod= 40-60
- severe= <40
ABGS

Chest imaging:
V/Q Scan
what are we looking for?
PE
