  42. During muscle contraction heads pull on the thin filaments causing them to slide toward the H zone. As the filaments slide inward the sarcomere shortens but he size of the filaments NEVER change. The sliding promotes shortening of the sarcomere and eventually of the entire muscle.
    • Sliding filaments mechanism 
    • -Muscle Contraction-
  43. Power Stroke
    • While in relax state ATP is attached to an specific binding site in the Myosin head. When activated it splits into ADP + P transferring energy and activating the Myosin head which move toward its actin binding site. Once Ca++ activates the actin regulatory proteins the Myosin heads spontaneously bound accomplishing the sliding process.
    • The process will repeat over and over as long as there is ATP and Ca++
  44. Muscle Contraction Steps
    • 1- Myosin heads hydrolyze ATP and become reoriented and energized.
    • 2- Myosin heads bind to actin, forming crossbridges
    • 3- Myosin heads rotate toward center of the sarcomere (power stroke).
    • 4- As myosin heads bind ATP, the crossbridges detach from actin.
  45. Relaxation
    Ach is rapidly broken down by AChe (Acetylcholinesterase) promoting closure of Na+ channels. This is followed by active recovery of Ca++ through a special pump which returns it to the sarcoplasmic reticulum where CALSEQUESTRIN molecules bind to Ca++

    Ca++ concentration in relaxed muscle is 10,000 times lower inside the cytoplasm than inside the sarcoplasmic reticulum.
  46. Contraction requires enormous amount of energy for Ca++ delivery into sarcoplasmic reticulum allowing for relaxation.
    Muscle metabolism
  47. Energy sources for muscle metabolism
    • Creatine phosphate (100 meter dash)
    • Anaerobic respiration (200 meters)
    • Aerobic respiration
  48. This is 3-6 times more plentiful than ATP inside the sarcoplasm. When contraction begins and ADP levels increase CK catalyzes the transfer of phosphate group back to ADP regenerating ATP
    This source is good only for a fraction of time
  49. Anaerobic respiration
    • Glucose is broken down into 2 molecules of Pyruvic acid with a net gain of 2 ATP. During exercise there is no delivery of enough oxygen and this prodces the accumulation of lactic acid which diffuses into the blood and may be converted back to glucose in the liver.
    • Through this process there is the production of energy that lasts up to 30-40 additional seconds.
  50. Aerobic respiration
    • If muscle activity lasts longer than 30 seconds it will depend only in aerobic respiration.

  137. What will be the physiological difference between an athletic and a sedentary subject with respect to the results observed during the laboratory experience?
    • a.  Increased myocardial contractility and tone. This increases the amount of blood flow without exerting as much energy, resulting in a lower heart rate after exercise than in a sedentary subject.
    • b. Increased lung capacity. This increases the amount of oxygen available to be delivered to the tissues in a single breath, resulting in less hyperventilation than in a sedentary subject. 
    • c.   Increased anaerobic threshold. An increased period of anaerobic respiration will result in a longer burst of powerful energy in an athlete than in a sedentary subject. 
    • d.  Increased gas exchange in the alveoli. Increased gas exchange at the alveoli results in fewer breaths required to provide the same amount of oxygen to the tissues. This will result in a decreased active rate of respiration in an athletic versus sedentary subject, however it will still be higher than the resting rate of respiration.
    • e. Decreased levels of blood lactate. Due to an increased anaerobic threshold, an athletic subject will have lower levels of lactic acid production.

  164. General Healh- history
    Detailed history with regards to differential diagnosis of fatigue, weight loss, fever, headaches, dizziness, and malaise
  165. Fatigue
    • Feeling of weariness, tiredness, or lack of energy.
    • Functional causes: emotional stress, anxiety, depression.
    • Endocrine disorders: Addison’s disease, thyroid disease, diabetes mellitus.
    • Neurologic disorders: Myasthenia gravis.
    • Infectious disease: hepatitis, mononucleosis, tuberculosis, intestinal parasites, endocarditis
    • Respiratory disorders- emphysema
    • Hematologic disorders- Anemia
    • Autoimmune disorders- rheumatoid arthritis, systemic lupus erythematosus. – important- pt uses steroids
    • Neoplasic disease.
    • Drugs- Alcohol. Sedative hypnotics, environmental toxins
  166. Other medical conditins that can be manifested with fatigue
    Hypothyroidism, Diabetes, Hypertension, GI problems, Respiratory problem, neoplasia, mental conditions, depression
  167. Chronic Fatigue Syndrome
    a term coined and not a specific conditional disease. Leukemia in children will have a main manifestation of fatigue. So we must find the probable cause of the fatigue by asking questions. We can order tests to be done because we also see other manifestations such as dizziness etc. thus getting us closer to a definite diagnosis.
  168. Good starts in diagnosing fatigue
    • Questions such as asking about what kind of medication they take is a good start and also, their age and occupation. With meds most pts don’t know the name and think that OTC are not meds so they won’t tell you. But in fact the meds can cause as side effects, fatigue and dizziness, etc.
    • Diabetes pts take the medicine and think they can eat whatever but with all that sugar in the system, not as much oxygen is getting to the cells and creates the feeling of tiredness
  169. Weight loss
    • Can occur due to disease of any organ system or also in the absence of serious physical illness. Exercise, and diet. Can be due to psychological problems (depression, anorexia, nervosa, bulimia).
    • Many endocrine conditions will produce this weight loss. Would ask for a CMP (comprehensive metabolic Panel), and CBC, triglycerides. If suspecting of chronic disease and depending on the location and history, you can order imaging tests.
  170. Fever= pyrexia
    • Fever is a natural reaction of the body to an illness and actually helps the body fight infections.  It is not an illness.
    • A fever is present when the temperature is above 100.5°F (38.0°C) rectal or 99.5°F (37.5°C) oral or ear.
    • If pt complains of fever then it must be documented using a thermometer, and not by using the back of the hand.
  171. Causes of fever
    • Physiologic causes
    • Autoimmune disease
    • CNS disease
    • Hematologic disease
    • Cardiovascular disease

  176. Cardiovascular disease
    myocardial infarction, pulmonary embolism, endocarditis.
  177. GI disease
    inflammatory bowel disease, liver abscess.
  178. Endocrine disease
    hyperthyroidism, pheochromocytoma.

    Chemical agents: drugs, anesthesia, infection.
  179. Miscellaneous causes
    psychogenic fever, sarcoidosis, chronic fatigue syndrome.
  180. Grades of fever
    • Temperature between 99.8° F - 100.8° F is considered a low-grade fever.
    • Between 101° F - 102° F is considered a mild fever.
    • Temperature between 102° F - 103° F is considered a moderate fever.
    • Around 104° F or above is considered a high fever, and delirium or convulsions may occur.
  181. Other causes of fever
    • If pt have had a vaccination in recent days, they will have a slight increase in temp due to the fact of attenuated virus, bacteria, etc. depending on the child, if the temp is about 104 or higher then they might have convulsions although some books say around 108 but you won’t wait until they reach that temp to find out.
    • If rash is present with a fever you must act quick because can be caused by meningitis. Collagen related diseases also known as immune related diseases such as rheumatoid arthritis, lupus, etc. and can have many manifestations in different organs and will cause fever. Sometimes chronic diseases can produce fevers and thus conduct tests to determine the cause.
  182. Unknown fever Origin
    • Fever over 3 weeks duration, after routine workup there is no diagnosis.
    • More than 30% of Fever unknown origin cases in persons older than 50 years are related to connective-tissue disorders and vasculitic disorders.
    • Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are the two principal connective-tissue etiologies, accounting for 50% of the cases.
  183. When the fever is an emergency
    • If the person /child:
    • Acts confused or delirious.
    • If a child is under 60 days old (2 months) and has a temperature of 100.5°F  need to be seen by a physician right away.

    • When such red flags are present, neuroimaging (computed tomography [CT] or MRI) is indicated to investigate secondary causes of headache.
  194. Dizzy
    • having a whirling sensation in the head with a tendency to fall.
    • Ask the pt to describe their symptoms by using words other than “dizzy.” the rationale for using other words is that pt’s

  195. Vertigo
    • a disordered state in which the individual or his surroundings seem to whirl.
    • Vertigo, a symptom of a balance disorder, is the illusion of movement when no movement is present. This can be caused by a problem of the inner ear balance mechanisms, or by a problem in the brain. While usually harmless, vertigo can be a sign of a serious condition if accompanied by difficulty in speaking or walking, severe headaches, or double vision.
  196. Causes of Vertigo
    • Benign paroxysmal positional vertigo or BPPV, which is caused by an inner ear problem and is the most common cause of vertigo. BPPV is characterized by sudden and severe episodes that are nonetheless not serious.
    • Inflammation or infection of the inner ear, which can lead to hearing loss if not treated immediately.
    • Certain serious medical conditions, including multiple sclerosis and head or neck trauma.
    • Cerebellar hemorrhages, which cause vertigo because of decreased blood flow to the brain. In this case, vertigo is accompanied by more serious symptoms, such as difficulty walking and vision impairments.
    • Meniere disease, which often also causes ringing in the ear.
  197. Malaise
    • A vague body discomfort as in premoribid state of an illness or depression.
    • Subjective feeling of being sick, ill, or not healthy. The feeling is generalized, varying from mild to severe in intensity. It may be the lone clinical manifestation of malaria, or may accompany other signs and symptoms, such as fever, headache, or nausea.

  264. Principles of basic cardiac life support CPR = cardiopulmonary resuscitation
    • Basic life support (BLS) is a specific level of prehospital medical care provide by trained responders in the absence of advanced medical care. Most laypersons can master BLS skill after attending a short course.
    • BLS consists a number of life-saving techniques (“ABCs”) of prehospital emergency care:
