16
Q

what is the appropriate temperature of the hydrocollator?

A

158-169 degrees farenheit

17
Q

how many layers of towels are needed with hydrocollator packs?

A

6-8 layers or 4 with terry cover

18
Q

how long should a hydrocollator pack be used for treatment?

A

20 minutes

19
Q

what is the appropriate temperature for a warm whirlpool?

A

86-100 degree farenheit

20
Q

what is the treatment time for the warm whirlpool?

A

10-45 minutes

21
Q

temperature of water for whirlpool must be ____ if the size of the body part is _____

A

lower; bigger

22
Q

additional contraindications for whirlpool?

A

incontinence
fever
MS
1st tri of pregnancy

23
Q

what is used for soaking the perianal/ anal area for pain or itching; hemorrhoids?

A

sitz bath; 72-100 degrees

24
Q

what is the ratio needed for the paraffin bath and what temperature is used?

A

6:1 paraffin/mineral oil

124-129 degrees F

25
Q

how many times do you dip with paraffin tx and what is the treatment time?

A

6-10 times dipping

30 minute treatment time

26
Q

what is different about paraffin immersion vs paraffin dipping?

A

on the 10th time dipping leave the extremity in the bath for the remainder of the treatment

27
Q

what is a dry cellulose heated to 110-126 degrees F then blown around a chamber by fans?

A

fluidotherapy

28
Q

what is the treatment time for fluidotherapy?

A

30 minutes

29
Q

what is the treatment time for infrared lamp?

A

15-20 min

30
Q

the amount of heat needed for infrared lamp depends on:

A

length of time exposed
distance from the bulb
angle from perpendicular
output of bulb

31
Q

the intensity varies with the inverse square of the distance between the bulb and skin, this is called?

A

inverse square law

32
Q

examples of inverse square law

A

change from 20cm to 10cm= 1/2 distance
inverse of 1/2= 2
square of 2=4
therefore 4x more heat needed with 1/2 the perpendicular distance

33
Q

intensity of heat decreases with change from perpendicular, what law is this?

A

cosine law- rotate 30 degrees from perpendicular
cosine of 30 degrees =86
therefore intensity of heat at 30 degree is 86% of original intensity

34
Q

when is a contrast bath used?

A

in the subacute phase

35
Q

what treatment is used to allow transition from cold modalities to warm modalities and isn’t good for swelling?

A

contrast bath

36
Q

what is the time for contrast bath?

A

1-4 min for 1st
1-4 min for 2nd
alternate for 20-30 min

37
Q

end with cold when needing _____ and end with hot when needing ______

A

vasoconstriction; vasodilation
