Random Flashcards
volt
the electrical force capable of moving charged particles through a conductor between two regions or points.
hertz
a unit of measure which describes the number of cycles per second when using an alternating current
coulomb
amount of electrical charge transported in one second by a steady current of one ampere.
Pulses per second
utilized to describe the frequency of pulsed current
anemia
heart palpations , shortness of breath
coagulant disorder
susceptibility to bruising
stage 1 ulcer
characterized by an observable pressure related alteration of intact skin whose indicators, as compared to an adjacent or opposite area of the body, may include changes in skin color, temp, stiffness, or sensation.
stage 2 ulcer
partial thickness skinloss that involves the epidermis and/or dermis. Superficial and presents as a clinical abrasion, a blister or a shallow crate.
stage 3 ulcer
full thickness skin loss that involves damage or necrosis of subcutaneous tissue that may extend down to but not through, the underlying fascia. Presents as a deep crater with or without undermining adjacent tissue.
stage 4 ulcer
full thickness loss with extensive destruction, tissue necrosis or damage to muscle, bone or supporting structures.
Inspiration muscles
Diaphragm (main)
Upper trapezius
External interostals (Secondary)
Expiration muscles
Internal intercostals (main)
superficial burn
involves only the outer epidermis .
red with slight edema
No scar healing in 2-5 days
super ficial partial thickness burn
involves the epidermis and the upper portion of the dermis.
Painful with blisters
Healing occurs in minimal to no scaring in 5-21 days
a deep partial thickness burn
complete destruction of the epidermis and upper portion of the dermis
discolored with broken blisters/edema
Damage to the nerve endings may result in only moderate pain
Healing for hypertrophic scars and keloids in 21-35 days
full thickness burn
complete damage of epidermis and dermis and partial damage to subcutaneous fat layer
eschar formation
no pain
require grafts and susceptible to infection
Compression garments:
10mmHg: not adequate edema control
- 16-18mmHg: off the shelf stockings used to prevent DVT in bed ridden patients.
- 20-30mmHg: used to control scar tissue formation.
- 30-40mmHg: used to control edema in ambulatory patients.
Best indicator that the pt. exerted maximal effort
failure of the heart rate to increase with further increases in intensity
acceleration
rate of change in velocity with no respect to time
cadence
number of steps taken by a person per unit in time
110 steps typical in male
115 steps typical in female
velocity
rate of linear forward motion in the body
measured in cm per sec
= distance dived by time
Grade 1 Joint mob
small movement performed at beginning of range
Grade 2 Joint mob
II large amplitude movement performed within the range, but not reaching limit of range and not returning to beginning of range
Grade 3 Joint mob
large amplitude movement performed to limit of range
