Term
Aerobic capacity
Definition
a measure of how efficiently your heart and lungs can transport oxygen-rich blood to your working muscles.
Term
Aerobic Capacity aka
Definition
cardiorespiratory fitness
Term
Aerobic capacity is measured in terms of
Definition
VO2 max or max O2 uptake.
Term
Name an example of a “cardiac symptom”:
Definition
SOB, chest pain
Term
CO equation
Definition
CO=SV X HR
Term
Cardiac output
Definition
is the amount of blood pumped through the body in one minute
Term
Stroke volume
Definition
how much blood is pumped out of the ventricle and into the system with each contraction
Term
How can you increase cardiac output?
Definition
•increase heart rate
•increase stroke volume
Term
BP equation
Definition
BP=CO x TPR
Term
And we know CO=SV x HR, so BP =
Definition
P = (SV x HR) X TPR
Term
TPR=
Definition
total peripheral resistance=pliability of the vessel
Term
When we have a low TPR, BP is
Definition
normal
Term
When we have high TPR, BP is
Definition
high
Term
Systolic BP
Definition
highest pressure inside the arteriole
Term
Diastolic BP
Definition
lowest pressure inside the arteriole
Term
Symptoms of low BP
Definition
dizziness, cold & clamy (aka diapheuretic)
Term
Symptoms of high BP
Definition
no predictable symptoms
Term
What info do you get from the chart review?
Definition
Indirect history info
Term
What info do you get from the subjective interview of the patient?
Definition
Direct history info
Term
Name a few pieces of info you’d collect from the indirect history:
Definition
•lab values
•radiologic studies, diagnostic tests
•oxygen therapy delivery
•electrocardiogram
Term
Name modifiable risk factors for CAD
Definition
Smoking
Hypertension
Hypercholesterolemia
Sedentary lifestyle
Stress/psychosocial concerns
Obesity
Diabetes
Term
Name non-modifiable risk factors for CAD
Definition
Fam hx of heart disease Age (men=40-45) (women=55 [post-menopause]) Gender (more prevalent in men than women) Race (more prevalent in africanamerican pop)
Term
Name five vital signs
Definition
BP
HR
Auscultation of heart/lungs
Temperature
RR
Pulse Oximetry (SpO2)
RPE
Pain
Term
Name 4 locations for heart auscultation
Definition
Aortic
Pulmonary
LLSB
Mitral
Term
Systolic BP increases with increased or decreased exertion?
Definition
Increased
Term
Diastolic BP should maximally increase by only __mmHg when rising from a resting position.
Definition
10 mmHg
Term
be able to draw time vs volume graph for lung volumes....key is on the back.
Definition

Term
VT
Definition
tidal volume=the volume of air normally inhaled and exhaled with each breath during quiet breathing
Term
IRV
Definition
inspiratory reserve volume=the additional volume of air that can be taken into the lungs beyond the normal tidal inhalation
Term
ERV
Definition
expiratory reserve volume=the additional volume of air that can be let out beyond the normal tidal exhalation
Term
RV
Definition
residual volume=the volume of air that remains in the lungs after a forceful expiratory effort
Term
IC
Definition
inspiratory capacity=the sum of the tidal and inspiratory reserve volumes (IRV+VT=IC) it is the max amount of air that can be inhaled after a normal tidal exhalation
Term
FRC
Definition
functional residual capacity=the sum of the ERV and RV. It is the normal amount of air remaining in the lungs at the end of a normal tidal exhalation.
Term
Why is the FRC important?
Definition
It represents the point at which the forces tending to collapse the lungs are balanced against the forces tending to expand the chest wall
Term
VC
Definition
vital capacity

The sum of IRV, VT, and ERV. It is the max amount of air that can be exhaled following a maximum inhalation.
Term
TLC
Definition
not only introduced you to the bumpin 90’s hit song “No Scrubs”, but TLC also stands for total lung capacity. It is the max volume to which the lungs can be expanded. It is the sum of ALL the pulmonary volumes because the band TLC was a SUM of ALL 3 bad ass bitches that didn’t want no scrubs hollain at them.
Term
Normal ratio of inspiration to expiration
Definition
1:2
Term
Normal RR
Definition
12-16 breath/min
Term
How do you get a patient to activate their diaphragm?
Definition
Have them sniff
Term
What does pursed lip breathing help with?
Definition
Expiration
Term
What is the professorial position? What does it suggest the patient has?
Definition
Leaning forward with UE’s in closed chain. Emphysema
Term
What is the Semi-Fowler’s position and what does it suggest the patient may have?
Definition
Head of bed elevated, or patient propped up on multiple pillows
CHF
ex/ 3 pillow orthopnea
Term
What is orthopnea?
Definition
SOB/difficulty breathing while lying flat
Term
[image]
Definition
postures from L to R
1.normal 2. Barrel chest 3. Kyphosis 4. Pectus excavatum 5. Pectus carinatum
Term
What is digital clubbing?
Definition
Associated with sever, chronic hypoxemia
Nail beds are bulbous and cyanotic
Term
Name the 6 questions to include in a pulmonary screen:
Definition
CSHDCX

Carrie Stella Hates Dirty Cheerleaders X-plicitly

Coughing
Sputum production
Hemoptysis (blood in sputum)
Dyspnea (difficulty breathing)
Chest discomfort
when was your last chest X-ray
Term
What should be louder….inspiration or expiration? Why?
Definition
Inspiration because it’s active
Term
What is the term for low muscle mass?
Definition
Cachectic
Term
What is the term for collapse of a segment or lobe of the lung?
Definition
Atelectasis
Term
Atelectasis is when the ______ _____ pop in the distal airways (where gas exchange occurs)
Definition
Alveolar sacs
Term
Common cause of atelectasis:
Definition
Taking shallow breaths
i.e. rib fx or post-anesthesia
Term
What is hypoxemia?
Definition
Decreased PaO2 (partial pressure of arterial O2)
Term
Name the 5 causes of hypoxemia
Definition
DHAMS dudes have awesome mouth skills....so they don't get hypoexmia when they go down

1. decreased inspired oxygen
2. hypoventilation
3. alveolocapillary diffusion problem
4. V/Q mismatch (ventilation/ profusion mismatching)
