Q

UE exercise vs LE exercise

A
  • UE has 30% increase in sympathetic activity - increases HR more markedly
  • BP increases more markedly in UE exercise d/t lower mechanical efficiency and recruitment for stabilizing postural muscleds
  • UE exercises produces increased BP and HR response

Q

valsalva

A
  • intrathoracic pressure increased aganist closed glottis
  • collpased IVC and SVC reduce BP and HR

Q

white blood cells

Study These Flashcards
A
  • leukocytosis - too high (>11) -> infection
  • leukopenia - too low (<4) -> chemo
  • neutropenia - way too low (<1.5)

normal 5.0-10.0 10^6/L

18
Q

platelets

Study These Flashcards
A
  • thrombocytosis - too high (> 450)
  • thrombocytopenia (< 150)

140-400 k/uL

19
Q

hematocrit

Study These Flashcards
A
  • polycythemia - too high
  • anemia - too low
20
Q

normal vs abnormal EKG w/ exercise

Study These Flashcards
A
  • normal
  • P wave increases in height
  • R wave decreases in height
  • J point depressed
  • ST segment sharply up sloping
  • Q-T interval shortens
  • T wave decreases in height
  • abnormal
  • excess ST segment depression > 2 mm
  • ST elevation > 1mm
  • increase PR interval
  • missing Q
  • missing P
  • increase/decrease wave time
21
Q

if you’re looking at EKG leads, PT should look at

22
Q

EKG interpretation

Study These Flashcards
A
  • P-wave: atrial depolarization
  • P-R interval: atrial depolarization, SA to AV
  • QRS complex: atrial repolarization, ventricular depolarization
  • QT interval: ventricular depolarization and repolarization
  • ST segment: time ventricles are depolarized
  • T wave: ventricular repolarization
23
Q

heart block

Study These Flashcards
A
  • heart electrical system disease
  • 1st degree: PR interval lengthened, delayed conduction from atria to ventricles through AV node
  • 2nd degree- type 1: progressively longer PR interval
  • 2nd degree - type 2: purkinje fiber diseaes, repeated P waves -> progress to complete heart block
  • 3rd degree: block in purkinje system, life threatening
24
Q

breath sounds

Study These Flashcards
A
  • crackles/rale - CHF, pulmonary edema/fibrosis, infection of small bronchioles
  • wheezes - high-pitched wheezing , asthma
  • rhonchi - low pitched wheezing, pneumonia, bronchitis, COPD, cystic fibrosis
  • stridor - high pitched airway, upper airway blockage
  • cheyne-stokes respiration - rapid breathing followed by apnea/cardiac failure
25
postural draininage
26
aerobic exercise prescription
- 40-85% of HRR - HRR = HRmax - HRrest
27
indications/contraindications for cardiac rehab
- **indications** - medically stable post MI - stable angina - CABG - stable heart failure - heart transplant - valvular heart surgery - pad, cad - **contraindications** - unstable angina - uncontrolled HTN - orthostatic BP drop - aortic stenosis - uncontrolled arrythmias - pericarditis/myocarditis - 3rd degree AV block w/o pacemaker - uncontrolled PE/DVT
28
cardiac rehab phases
- phase 1: inpatient, acute stay - phase 2: OP phase - phase 3: community program - self-regulated, 6-12 months
29
calcium channel blockers
- decrease entry of Ca into vascular smooth muscle - relax and widen BVs - diminished myocardial contraction, vasodilation, decrease O2 demand - decreases HR and BP - "-pine" & cardizem - "cookie monster says PINE cones are a great Ca source"
30
angiotensin converting enzyme (ACE) inhibitors
- decrease BP and afterload - suppress enzyme that converts Angiotensin I to Angiotensin II (which vasoconstrics) - results in decreased BP - "-pril" - "Ace-pril fools; aces -> now i can relax"
31
positive ionotropic agents
- increase force of muscular contractions - increases force and velocity of myocardial contraction, slows HR, decreases conduction through AV node (increases BP) - digitalis/digoxin - decreases HR for more efficiency - "I DIG star wars & the force"
32
beta blockers
- decrease myocardial oxygen demand by decreasing HR and contractility - block action of beta receptors on SNS in lung, heart - results in decreased HR and BP - interfere with bonding of epinephrine, norepinephrine - "-lol" - "If you use LOL on facebook, I beta block you"
33
biot's respiration
- ataxic respiration - periodic breathing hyperpnoea and apnea - poor prognosis, neuron damage
34
kussmaul breathing
- metabolic acidosis/diabetes mellitus - hyperpnoea - deeper breathing - K - ketones - U - uremia - S - sepsis - S - salicylates - M - methanol - A - aldehydes - U - L - lactic acid
35
cheyne-stokes respiration
- periodic breathing: gradual hyperpnoea, hypopnoea, apnea - shallow, deep, shallow, break
36
obstructive vs restrictive lung disease
- obstructive: makes airways smaller, oreo milkshakes; COPD, emphysema, chronic brinchitis, asthma, CF - restrictive: cannot fully fill lungs with air, restricted from full expansion; DMD, ALS, scoliosis
37
lung diseases and volumes
- obstructive: decr VC, IRV, ERV; increased RV, FRC, TLC - restrictive: decr everything
38
hemoglobin cut off
- if < 8, don't ambulate - only "essential daily activities"
39
hematocrit cut off
- <25% on essential ADLs
40
PaO2
- normal > 80 mmHg - no PT w/ partial pressure O2 < 60 mmHg
41
glucose cut off
- normal 80-120 - no PT < 70 or > 300
42
potassium cutoffs
- normal 3.5-5.0 for nerve impulse transmission, contractility of muscle
