Spirometry testing patient is coaching
preparation of a patient for spirometry: No smoking or using bronchodilators 6 hours before test. Explain process and purpose of test. Demonstrate if necessary, explain coach and cheer on patient since the test is effort dependent. Patient should be sitting in proper posture for test because they may become dizzy.

Causes diameter of chest front to back to expand, normally that should be about half the width of chest. Big barrel chest because waste air is not being expelled. subtype of COPD. obstructive disease: having to do with air flow; emphysema - outgoing breathing difficulty; shortness of breath and wheezing. At first, SOB (dyspnea) occurs with activity; as disease progresses, eventually at rest.

To treat an ulcer. An operation to remove the lower part of the stomach (antrum), which produces a hormone that stimulates the stomach to secrete digestive juices. Sometimes a surgeon may also remove an adjacent part of the stomach that secretes pepsin and acid. A vagotomy is usually done in conjunction with an antrectomy.

Crohne's disease
Crohn's disease is a form of inflammatory bowel disease (IBD). It usually affects the intestines, but may occur anywhere from the mouth to the end of the rectum (anus). With Crohn's disease the immune system can't tell the difference between normal body tissue and foreign substances with an overactive immune response that leads to chronic inflammation (autoimmune disorder). People with Crohn's disease have ongoing (chronic) inflammation of the gastrointestinal tract. There can be healthy patches of tissue between diseased areas. The inflammation causes the intestinal wall to become thick.
varicose veins
Dilated, tortuous, superficial veins in legs; contributing factors: pregnancy, obesity, prolonged standing or sitting, or sitting, heavy lifting, congenitally defective valves. Caused by venous insufficiency or valves not closing, allowing backward blood flow, causing vein to distend from increased pressure.

3 basic functions of EKG
EKG machine-recorder, amplifier, sensor: the sensor is the electrodes/lead portion of the machine capturing the data; the amplifier would amplify the data into something to be interpreted, the computer part of the machine; the recorder is the part of the machine that records the data on the EKG paper
EKG electrodes
are disposable, 12-Lead EKG uses 10 electrodes. Electrodes are small sensors placed on the skin to receive the electrical activity from the heart, and leads are covered wires that conduct the electrical impulse from the electrodes to the EKG machine.
EKG tracing, time is recorded on the?
horizontal axis-represents time: speed, rate, 0.04 seconds, 25 mm per second 25 little squares or 5 big squares per second. 1,500 small blocks equals 1 minute. 300 big blocks equals 1 minute. horizontal on EKG paper, each little square is 1 mm At the normal paper speed, one second equals 25 mm, or five heavy lines. Therefore, each vertical heavy line represents 0.20 of second.
few QRS complexes on EKG: less than 60bpm
Purpose: protects wound from injury and contamination; maintains constant pressure minimizing bleeding and swelling; holds wound edges together; absorbs drainage and secretions. Dressings are put directly over or in a wound. Because it is going directly in or on an opening into the body, it must be sterile.
bandages cover everything including the dressing, so they must be clean but not necessarily sterile. Purpose of bandage: Helps hold dressing in place; improve circulation; support or reduce tension or prevent movement.
consent form
Required before all minor surgical procedures. It is the provider's responsibility to get this signed by the patient. It is the MA's responsibility to make sure this was done but NOT to get the consent. Consent must be informed consent while the patient is alert and can understand and ask questions prior to the procedure.

wandering baseline
Wandering baseline shift, occurs when the tracing drifts away form the center of the graph paper. Baseline shift can have many causes. Typically, it is due to improper electrode application such as the following: Too loose or incorrect electrode application; Tension or pulling on electrode lead wires; Too little electrode gel or solution; Old or dried out electrode gel or solution; Corroded or dirty electrodes; Oil, lotion, or dirt under the electrodes, ALSO breathing
Einthoven's triangle

Atherosclerosis is a disease of the arteries in which fatty material and plaque are deposited in the wall of an artery, resulting in narrowing of the arterial lumen and eventual impairment of blood flow.
crackles and wheezing in lung base
Crackles or rales are because of fluid filled bronchioles. Wheezing is because of restricted bronchioles. (our notes)

Crackles: pneumonia, atelectasis, pulmonary fibrosis, acute bronchitis, or bronchiectasis, pulmonary edema.
Wheezing: lung disease; the most common cause of recurrent wheezing is asthma attacks. From internet, not the best source.

10 leads make 12 circuits
The 10 lead wires produce 12 different lead circuits consisting of one or more wires from the electrodes to the electrocardiograph. The 12 leads are made up of three different types of leads; three standard limb leads, three augmented leads, and six chest leads. The 12 circuits produce 12 different tracings or views of the heart. A 12-Lead EKG is actually recorded by only 10 lead wires, which, when attached to the chest and the limbs (arms and legs), provide the 12 different views for the 12-Lead tracing. Six of these leads attach to the chest electrodes, and the other four attached to the electrodes on the arms and legs.
