Lab Values
hematocrit - Male =
37-49%
- Rehab considerations (Physiopedia)
- <25% = No exercise
- 25-30% = light exercise
- >30% = Resistive exercise
Lab Values
hematocrit - Female =
36-46
- Rehab considerations (Physiopedia)
- <25% = No exercise
- 25-30% = light exercise
- >30% = Resistive exercise
Lab Values
Platelets= ______
what is the importance of this lab value?
150,000-400,000/µL
it measures blood clotting potential or inability
Lab Values
Hemoglobin - Male =
what is the importance of this lab value?
13-18
hemoglobin levels tell you about the patients O2 saturation potential
hemoglobin carries O2!
Lab Values
Hemoglobin - female =
what is the importance of this lab value?
12-16
hemoglobin levels tell you about the patients O2 saturation potential
hemoglobin carries O2!
Lab Values
Potassium:
Normal values =
Upper limit = ____\_
lower limit = ____\_
what is the importance of this lab value?
3.5-5.3
Upper limit = >5.1
lower limit = <3.2
irregular values indicate muscle weakness, arrhythmias, irritability, and issues with the heart
- ↓K- Hypokalemia (alkalosis, RF, D&V,diuretics) – Weakness, ileus, hypotonia, confusion, depression, arrhythmias, alkalosis.
↑K- Hyperkalemia (catabolism, acidosis, RF) – Cardiac arrest with VF. -
Reductions = Flattened T waves, arrthymias
- The T wave flattening can reflect low K+, widespread CAD, or L Ventricular Dysfunction from any other cause
-
Reductions = Flattened T waves, arrthymias
-
Elevations= Peaked T waves, shortened QT interval
- peaked t-wave = hyperkalemia, potential for transmural myocardial ischemia or a sudden, complete occlusion of a coronary artery
- short QT interval = causes disruption of the heart’s normal rhythm (arrhythmia).
Lab Values
Calcium=
what is the importance of this lab value?
8.5-10.5mg/dl (physiopedia, not given in med screen)
-
Reductions (Moderate to severe) = parathesias, muscle spasms and seizure and QT interval prolongation.
- In long QT syndrome, the heart’s electrical system takes longer than usual to recharge between beats
- QT prolongation may increase the risk of developing abnormal heart rhythms and may lead to sudden cardiac arrest.
-
Elevations (severe only) = Bradycardia, AV block, and short QT interval, coma
- short QT interval = causes disruption of the heart’s normal rhythm (arrhythmia).
Lab Values
WBC =_____\_
what is the importance of this lab value?
what are the considerations if you see the values: <5000, <5000+fever, <1000
4,500-11,000 for adults
- high levels = indicate an infection (nonspecific)
- low levels = pt is susceptible to opportunistic infection!
- <1000 = WEAR A MASK!
- <5000 + fever = NO EXERCISE, not cleared
- <5000 = LIGHT exercise only; use caution with an resisted exercises
Lab Values
c-reactive protein = _____
what is the importance of this lab value?
CRP: <5mg/l (physiopedia)
It is used as a predicitor for future MI, and CVA
produced by liver in response to trauma, inflammation, and infection
Physiopedia says c-reactive proteins are: An ‘acute phase’ protein
- Monitoring infections (>100, more likely to be bacterial)
- Distinguishing between AI diseases and active infection
- Monitoring RA Rx
- Checking for post-op infection
Lab Values
creatinine:
normal men = _____
normal women = ____
what is the importance of this lab value?
- men = 0.6-1.2 (physiopedia)
- women = 0.5-1.1 (physiopedia)
A creatinine test is used to see if your kidneys are working normally. It’s often ordered along with another kidney test called blood urea nitrogen (BUN) or as part of a comprehensive metabolic panel (CMP). A CMP is a group of tests that provide information about different organs and systems in the body
- Renal Function Tests - Urea & creatinine
- Urea: 2.5-6.5 mmol/l
- Cr: 60-120μmol/l
- Both should rise together in renal failure.
- Creat is the more accurate measurement, urea is affected more by diet and dehydration.
Lab Values
ESR (erythrocyte sedimentation rate)
normal men = ____
normal women = ____
what is the importance of this lab value?
Men = up to 17 seconds
women = up tp 25 second
- The erythrocyte sedimentation rate (ESR) is used as a diagnostic tool. As fibrinogen increases in acute inflammatory conditions, the ESR will also increase.
- An ESR test can help determine if you have a condition that causes inflammation. These include arthritis, vasculitis, or inflammatory bowel disease. An ESR may also be used to monitor an existing condition
Lab Values
what are the lab values to consider for platelets based upon these numbers:
<20,000µL
20,000-50,000µL
>50,000µL
< 20,000µL = NO EXERCISE
20,000-50,000µL = Light exercise (safer)
> 50,000µL = cleared for resistive exercise
Lab Values
What happens when potassium levels drop?
- ↓K- Hypokalemia (alkalosis, RF, D&V,diuretics) – Weakness, ileus, hypotonia, confusion, depression, arrhythmias, alkalosis.
- ↑K- Hyperkalemia (catabolism, acidosis, RF) – Cardiac arrest with VF.
Lab Values
FYI stuff about creatinine
- Renal Function Tests - Urea & creatinine
- Urea: 2.5-6.5 mmol/l
- Cr: 60-120μmol/l
- Both should rise together in renal failure.
- Creat is the more accurate measurement, urea is affected more by diet and dehydration.

hip disarticulation
the amputation of the lower limb through the hip joint

AKA - above knee amputation
aka. TRANSFEMORAL

name #4
knee disarticulation
Knee disarticulation is a muscle balanced amputation level that can be used in patients with diabetes, peripheral vascular disease, and trauma. Patients who are capable of sitting in a chair retain an excellent platform for sitting, a lever arm for transfer, and are unlikely to have joint contractures develop.

Syme’s amputation
Syme amputation (SA) is a term used to describe an amputation at the level of the ankle joint in which the heel pad is preserved. It is performed for a number of indications in a pediatric population. SA is purported to hold the advantage of allowing weight bearing without a prosthesis.

toe amputation
In knee disarticulations,
a muscle balanced amputation level that can be used in patients with diabetes, peripheral vascular disease, and trauma. Patients who are capable of sitting in a chair retain an excellent platform for sitting, a lever arm for transfer, and are unlikely to have joint contractures develop.

What is the difference between a ray amputation and a toe amputation?
Toe amputation is appropriate for wounds limited to the middle and distal toe and not involving the skin over the metatarsal head. More proximal wounds typically necessitate ray amputation. Ankle or digital nerve block is preferred for most toe amputations, but spinal, epidural, or general anesthesia may be chosen.
