how to take manual resting BP

1. have person seated and have their arm resting on table

2. place cuff 2-3 cm above elbow

3. align arrows on cuff with brachial artery

4. put stethoscope in ears so that you CANT see the holes

5. place bell on brachial artery

6. inflate cuff to around 180 (id do like 160 max)

7. SLOWLY deflate

first sound is systolic

last sound is diastolic

correct way to put stethoscope on

normotensive BP

elevated BP

120-129/

hypertension stage 1 bp

130-139/80-89

hypertension stage 2 bp

>140/>90

how to take manual resting HR (raidal artery)

1. feel pulse (felt on the wrist, under the thumb)

2. how many beats you feel for 10 seconds

3. multiply by 6 = # BPM

resting HR average

60 to 100

bradycardia

slow heart rate (less than 60 bpm)

tachycardia

fast heart rate ( greater than 100bpm)

lab 1 equations - age predicted max heart rate, and someof those trget heart rate zones on lab report 1

age predicted maximal heart rate

220 - age

HHR (hear rate reserve)

Max HR-Resting HR

(represents the range of heart rates your body can adjust to during exercise)

THR light intensity %

30 - 40 % HRR

THR moderate intensity %

40 -

THR vigorous intensity %

60 -

identify P wave

identify QRS wave

identify T wave

calculate R-R interval

count # of boxes b/w R of one and R of another then multiply by 0.04s = # secs

3 criteria for normal sinus rhythm

heart rate b/w 60 -100 bpm

< 3 small boxes of variability in the R-R intervals

each P wave precedes a QRS complex

where to place electrodes

just RA, LA, RL, and LL

(make sure u wipe skin w/ alc pad, and use the flat side of grippers

electrical pathway of the heart

SA node, AV node, bundle of His, bundle branches, and Purkinje fibers

calculate HR

1500 / the number of boxes from one R wave to the next R wave

SV = ?

EDV - ESV (end diastolic volume - end systolic volume)

cardiac output (Q) = ?

SV x HR

BP = ?

Q x TPR

tidal volume (TV)

volume of air moved during inspiration or expiration

Inspiratory Reserve Volume (IRV)

maximum volume of air that can be inspired above TV (3L)

Expiratory Reserve Volume (ERV)

maximum volume of air that can be expired below TV (1.3L)

Residual Volume (RV)

volume of air still in lungs after maximum exhalation (prevents lungs from collapsing)

VO2 = ?

Q x a-vO2diff

criteria for VO2 max test

1. VO2 plateau - VO2 increases by less than 150 ml/min with the last workload increase.

2. RER > 1.10

3. RPE > 17 (RPE = 17 does NOT count)

4. HR within 10 bpm of age-predicted max HR

need 3/4 !!!

Conversions (huh)???

HUHHHH

typical lactate levels at rest

1-2 mmol/kg of muscle

0.5-2 mmol/L of blood

typical lactate levels at max exercise

20-25 mmol/kg of muscle

30 mmol/L of blood

does lactic acid cause DOMS?

no!
