(Kevin, not sure what to do with this,you'll have to tell me)
Obstructive -
Which Pattern is this Flow Volume Loop
(short fat loop)
Normal -
Which Pattern is this Flow Volume Loop
Restrictive -
Which Pattern is this Flow Volume Loop
(tall skinny loop)
Very Round Loop Pattern on Flow Volume Loop indicates what? -
large, FIXED airway obstruction (like vocal cord paralysis or cancer)
What is minimum acceptable for FEV1 -
70%
If FEV1 is less than 70%, what is considered present? -
Obstruction
Normal FEV1 is 85%, but it should be at least ___% or higher on PFT -
80%
Body Box is "required" to measure what? -
Airway resistance (RAW)
What is the PURPOSE of Helium Dilution and Nitrogen Washout? -
To determine FRC (lung volume)
FRC is usually called ___________ when using a body box -
Thoracic Gas Volume
Spinal deformities, Atelectasis, Pnuemonia, ARDS are considered Obstructive OR Restrictive
disesases? -
Restrictive
What is the only obstructive disease associated with poor DLco (because it involves
destruction of alveoli) -
Emphysema
Normal DLco for all people regardless of height, weight, or age is ______mL CO/min/mmHg

Hemodynamic Normals for:
CVP, PAP, PCWP, CO -
CVP - 2-6 mmHg,
PAP - 13-15 mmHg or 25/8
PCWP - 7-9 mmHg
CO - 4-8 L/M

, Hemodynamics - from left to right in order, what pressures do you use to evaluate heart and
lung health? -
CVP, PAP, PCWP, CO
If all hemodynamic measures are "high" what does it mean -
"Too much water in the river" (patient should be diuresed)
If all hemodynamic measures are "low" what does it mean -
"Not enough water in the river" (patient is dehydrated, hemorrhaging, etc.; needs
fluids (blood or saline))
Bumex -
Potent Diuretic to get rid of excess fluid
MAP equation -
1x systolic + 2x diastolic / 3
Normal Range for MAP -
85-100 mm Hg
Normal Ranges: K+ (potassium)
Na+ (sodium)
Cl (chloride) -
K+ 4
Na+ 140
Cl 85-100
Normal Hb count for adult male -
14-17 g/dL
Normal Hb count for adult female -
12-15 g/dL
Normal Urine Output for adult -
30-50 mL/hr
Normal range for cardiac index in an adult -
2 - 4 L/min/m2
Equation for CO -
CO = SV x HR (stroke volume x heart rate)
Newborn's Vitals: HR, RR, BP -
HR 95-160
RR 30-60
BP 72/55
Newborn's: pH, PaCO2, PaO2, HcO3 -
pH 7.26 - 7.29 PaCO2 45-55
PaO2 45-65 HcO3 20-24
