Phys lab practical 2 :) Flashcards
What are the waves/intervals of reading a heart rate?
P Q R S T
What does a P wave look like?
The little bump up before the big spike
What does Q look like?
Little dip before the big spike
What does R look like?
BIG SPIKE :D
What does S look like?
Big drop after the big spike
What does a T wave look like
A weird medium sized hill AFTER the big spike and big dip
From top to bottom, what are the three screens on IX-TA for looking at the heart?
EKG, Pulse, Heart rate
What should you click to make the display zoom out on IX-TA
The 2 mountains
What should you click to zoom in on IX-TA?
The 1 mountain
What does autoscale look like on IX-TA?
Magnifying glass with up/down arrow in it (it’s to the right of the 2 mountains)
How do you find the R-wave amp?
Bottom and the peak of the big spike (R)
How do you find the beat period?
Top of big spike to top of next big spike (r-r)
How do you find the heart rate?
60/beat period in minutes (its given in msecs)
How do you find P-R intervals?
Before P (little bump before spike) and before R (big spike)
How do you find the Q-T intervals?
After Q (little dip before big spike) and T(weird medium hill after big spike+dip)
How do you find the T-P intervals?
After T (weird medium hill after big spike + dip) and before P (little bump before big spike)
How do you find the R-pulse intervals?
Top panel:
Top of R peak (big spike)
Middle panel:
Top of the next pulse (which is shortly after the R peak in the top panel)
How do you find the pulse wave amplitude?
MIDDLE PANEL:
Bottom and top of peak
How do you tell on IX-TA when the person started exercising?
Zoom out and there’ll be a big black line
What are the volumes/capacity names of reading respiration?
Tidal volume (TV)
Inspiratory reserve volume (IRV)
Expiratory reserve volume (ERV)
Residual volume (RV)
Inspiratory capacity (IC)
Functional residual capacity (FRC)
Vital capacity (VC)
Total lung capacity (TLC)
Where would you find the tidal volume?
Little waves before the big hill
Where would you find the total lung capacity?
Top to bottom of the while graph
Where would you find the IRV?
Top of TV to top of graph
Where would you find the ERV?
Bottom of tidal volume to the bottom of the medium sized dip after the big hill
Where would you find the vital capacity?
Top of the graph to the bottom of the ERV
Where would you find the residual volume?
Bottom of ERV to bottom on the graph
Where would you find the functional RV?
Bottom of tidal volume to the bottom of the graph
How do you calculate the TLC (liters)?
Add TV, IRV, and ERV to 1.2L
How do you calculate the TV?
Top and bottom of the little peaks
How would you calculate the IRV?
Top of the last TV (before the big peak) to the bottom of the big peak (other side of it- big dip)
How would you calculate the ERV?
Bottom of the last TV (before the big peak) to the bottom of the big peak (other side of it- big dip)
How do you calculate the VC?
Top of the big peak to the bottom of the big peak (in the big dip)
How do you calculate the RV?
Trick question: its 1200mL or 1.2L
