What is Clostidium Difficile
- When it over grows, it will release toxins that attack intestinal lining
- causes Clostridium difficile colitis
How can Clostidium Difficile be avoided?
Through good hygiene
Symptoms of Clostidium Difficile?
- Watery Diarrhea (15 times a day)
- severe abdominal pain
- loss of apetite
- blood or pus in stool
Who are at risk of Clostidium Difficile
- patients in hospitals
- longterm care facilities
What are Training Devices?
- devices doctors and nurses use when in training to develop skills
- Ex. virtual activites
What is information Technology?
a coordination of all the patients medical records in one place
What is the stethescope used for?
- for ausculation (listening to internal sounds)
- to examine the circulatory, repiratory and gastro intestinal system
- combined with sphygamomanometer
Who and when was the stethescope invented
What are the different types of Stethescopes?
Describe the Acoustic Stethescope
- sound travels via an airfilled hollow tube to ears
- other end made up of plastic disk or hollow cup
- disk or cup will vibrate causing waves in hollow
Describe the Electronic Stethescope
amplifies low level sounds
Describe the Fetal stethescope
- listen to heart of the fetus
- uses forehead
Who and when invented the Fetal stethescope
Describe the Doppler Stethescope
measure doppler effect of ultrasound waves reflected from body.
What is a sphygmomanometer?
a blood pressure measure
What is the operation of a sphygmomanometer?
- 1) place cuff around upper arm
- 2) be in a seated position
- 3)inflate cuff until artery is blocked
- 4)slowly release pressure
- 5)listen to brachial artery
- 6)listen for expansion and contraction of artery when blood begins to flow through
- Initial sound is systolic
- final time is diastolic
What is Systolic Pressure?
pressure in arteries when the heart contracts
What is diastolic pressure?
pressure in arteries when the heart relaxes
What is an X-Ray?
- highly penetrating ionizing radiation
- used to take pics of dense tissue (bones,teeth,tumors)
- dense tissue absorbs radiation
- radiation passes through body onto radiographic film
How does an X- ray work?
- cathode and anode in x-ray tube
- cathode releases energy as electric current
- anode attract electron
- causes energy (photons) to be released
- X-ray beam is only absorbed by dense materials
- radiographic film is behind it
- photons reach film and rxn occurs
- black= photon reach
- white= photon absorbed
What is an ultrasound?
uses high frequency sound waves to create images
How does an ultra sound work?
- sound waves are emitted from a high-frequency probe into patients body
- either reflected back or taken in by body
- sound wave is converted into electrical signal
- strength of sound corresponds to brightness of image on monitor
What does CT scan and CAT scan stand for?
- Computerized tomography
- Computerize Axial Tomography
Who and When was CT Scan invented?
What is a CT scan?
produces a series of x-rays slices of the body
CAT scan operation?
a patient will lie on a table that moves through an x-ray machine as it rotates around the body.
What is CT scan used to diagnose?
brain, neck,, spine, chest, abdomen
What does MRI stand for?
Magnetic Resonance Imaging
What is an MRI?
it uses strong magnetic fields and radio waves to form images
What are prosthetics?
An artificial device that replaces a missing body part
What is an upper extremity prosthese?
- include should elbow and wrist disarticulation (seperation at joint), full hand, partial hand, finger partial finger
- Transhumeral or transradial
What is Transhumeral Prosthesis?
(AE) above elbow
What is Transradial Prosthesis?
(BE) Below elbow
What is Lower extremity prosthese?
transfemoral prosthesis, knee disarticulation, transtibial prosthesis, symes disarticulation.
What is a transfemoral prosthesis?
- Above the knee
- use more energy to walk
What is knee disarticulation? And advantages / disadvantages
- done between bone surface
- limb can tolerate heavy weight
- retain full length femur
- increase stability
- knee extends beyond actual knee
What is a transtibial Prosthesis?
Below the knee
What is symes disarticulation?
- through ankle
- can have weight on remaining part of foot
Different types of prosthetic limbs?
- Cable operated
- Myoelectric operated
Explain cable operated prosthetic limbs
attach harness or cable around opposite shoulder of damaged arm
Explain Myoelectric limbs
uses electrodes to sense when muscles in remaining portion move
What are the 3 prosthetic components?
Explain prosthetic component: interface
where body attaches to the prosthesis
Explain prosthetic component: Components
the working part of the prosthesis
Explain prosthetic component: cover
assist with covering prosthetic to make it match skin
