Detailed & Elaborated) Graded A+ / 2025 Version!!
What is the FEV1/FVC ratio? - ANSWER-Comparison of volume
of air exhaled
in one second vs total
volume
Used to test for obstructive
disease
What is a normal FEV1/FVC ration? - ANSWER-Anything over
0.7
What is diffusion capacity? - ANSWER-Measures the diffusion
of air in and out
of the
lungs
What is expiratory flow limitation? - ANSWER-Expiratory flow
cannot increase despite increasing expiratory efforts
Predisposes to hyperinflation due to air trapping
,Presents commonly in obstructive diseases (slope of expiration
is decreased because of obstruction)
What is dynamic hyperinflation? - ANSWER-Increase in end-
expiratory lung volume (EELV) that may occur in patients
with airflow limitation when minute ventilation increases
(exercise) Due to reduced elastic recoil of lungs
How does obstructive disease shift the flow volume loop? -
ANSWER-Shifted to
the left (RV is increased due to air
trapping)
Expiration is not as steep (FEV1 decreased due to
obstruction)
Expiration is decreased
(Reduced ERV)
How does restrictive disease shift the flow volume loop? -
ANSWER-Shifted to
the right (reduced
RV)
Decreased expiration
(Reduced ERV)
Smaller figure (Reduced VC
and TLC)
,What are the 5 circumference points? - ANSWER-- Arm
(midpoint between acromian and olecranon)
- Waist (midpoint of iliac crest and ribs)
- Hip (furthest protrusion of glutes)
- Thigh (midpoint of inguinal crease and patella)
- Calf (furthest protrusion)
What kind of exercise can help relieve pain from spinal
stenosis? - ANSWER-
Relief in biking (forward bending
of spine)
Increasing strength of supporting muscles in back Stretching
can help loosens
muscles that pull
spine
What is vertebral disc protrusion? - ANSWER-Outermost layers
of intervertebral
discs of the spine bulge when the discs are under pressure;
may compress
nerves and cause pain or
numbness
, What is vertebral disc herniation? - ANSWER-Degeneration of
the outermost layer of the vertebral disc resulting in the inner
layers slipping out; results in pain, tingling, numbness, can
compress spinal cord
What kind of exercises are beneficial for disc herniation? -
ANSWER-Stretching
helps reduce back
tension
Back/core strengthening
exercises
What is scoliosis? - ANSWER-Curvature of the spine in the
frontal plane; can
cause pain in back and shoulders, may also cause
respiratory/cardiac issues
and limited
mobility
What are some beneficial exercises for scoliosis? - ANSWER-
Stretching and
strengthening can help reduce abnormal angles
in the spine
