Question 1

Hydrotherapy

Answer 1

pool therapy,
whirlpool, and pulsatile
lavage (or spraying
wound with water).

Question 2

Water Has 4 Properties…

Answer 2

• Heating or cooling
• Buoyancy
• Resistance
• Hydrostatic pressure

Question 3

Heating or Cooling- Hydrotherapy

Answer 3

conduction or convection

Question 4

Buoyancy- hydrotherapy

Answer 4

Upward thrust on the
body, opposite the force
of gravity

Question 5

resistance- hydrotherapy

Answer 5

Provided by the viscosity of
water. Increases with speed of
motion, or with surface area
exposed to water.

Question 6

hydrostatic pressure-hydrotherapy

Answer 6

Pressure exerted by the water on all sides of a
body part. This increases with depth of water. At
4 feet under water, the pressure exerted will be
about 89 mm Hg, which is slightly more than
normal diastolic BP. This pressure can promote
circulation, alleviating edema.

Question 7

effects of hydrotherapy

Answer 7

• Integumentary
• Musculoskeletal
• Cardiovascular
• Respiratory
• Renal
• Nervous – (psychological effect)

Question 8

Hydrostatic pressure
increases blood flow to
muscles by…

Answer 8

100-200%

Question 9

Hydrostatic pressure pushes
blood from periphery to
thorax and heart. Increased
central blood volume,
increased cardiac volume.
Response of heart is…

Answer 9

increased cardiac
contraction and stroke
volume

Question 10

RPE= Rate of Perceived Exertion

Answer 10

• Patient rates how hard an activity is
• Scale usually goes from 6-20 or the modified
  scale is from 1-10

Question 11

Due to increased venous
return to heart and chest
cavity, resistance to lung
expansion is increased.
Vital capacity…

Answer 11

decreases by about
10%, increases work of
breathing by 60%.

Question 12

renal hydrotherapy

Answer 12

Due to increased central
blood volume, urine
production increases.
