Prone position
face down
divides left and right side of heart
increases blood flow with a decrease in vascular resistance , causing a decrease in BP
decreases blood flow with an increase in vascular resistance, causing an increase in BP
Coronary arteries
supply blood to the heart; located just above the aortic valve
Arteries--> veins
arteries--> arterioles--> capillaries--> venuoles --> viens

--- capillaries are the sight of oxygen and CO2 exchange
Ischemia/ Acute Coronary Syndrome (ACS)
insufficient blood supply which leads to insufficient oxygen and nutrients (blood flow to the heart is cut off); heart is deprived of oxygen;

---presents with chest pain or discomfort, diaphoresis, anxiety
plaque and calcium build up; can block the artery , thus block blood flow; usually causes ACS

peripheral nervous system; nerve fibers (sensory and motor); sensory from body to brain and motor from brain to body
cerebrospinal fluid ; acts as a shock absorber ; when pts have fluid draining from ears or nose , it is CSF and they have a head injury
somatic nervous system; voluntary
autonomic nervous system; involuntary; organs; consists of sympathetic and parasympathetic
fight or flight response; epi is released in stressful situations
responsible for stimulation of activities that occur when the body is at rest, especially after eating, including sexual arousal, salivation, lacrimation (tears), urination, digestion and defecation; ex: vessels dilate and sphincters are relaxed
temporary loss of alteration of the brains ability to function; unconsciousness, dizziness, weakness, visual changes, nausea; lasts only a short time (depends on the seriousness)
aka bruise (ecchysmia) associated bleeding from blood vessels; increase in pressure

Spinal Injuries
occur as a result of a significant fall; axial loading; vertical injury of the spine
When the spine is forced backwards into an exaggerated arch; most common way children injure their spinal cords;
Hyper flexion
When the spine is forced forwards into a tight curve ; "whiplash" from MVA
MVA or other types of trauma ; Often occur alongside a flexion injury, where there is rotation of the spinal column, often in the cervical, lower thoracic and lumbar regions; ligaments are torn; MVA when vehicle is hit from the side, lap seat belts, and motorbike accidents
AVPU scale
a system by which a health care professional can measure and record a pts responsiveness, indicating their LOC
S&S of spinal injuries
---pain in spinal area or extremities
---loss of feeling of function of extremities and other bodily functions
General principles of care for head injury
1) establish adequate airway
2) control bleeding
3) assess LOC and continue to monitor it
Stabalization of the cervical spine
---apply manual stabalization immediately
---assess P, motor function, and sensation in extremities
---assess cervical spine area and neck
---apply a collar
---maintain manual support until pt is secure on backboard
---do not force the head into a neutral, inline position
Helmet removal
if helmet is blocking access to the airway, ALWAYS remove it

---keep constant stabalization of the neck and spine
each cell combines nutrients and oxygen and produces energy and waste products ; every living cell in the body requires oxygen and a means of disposing of waste
a passive process in which molecules move from an area of higher concentration to an area of lower concentration (O moves from alveoli into capillaries cause there are fewer O molecules in the capillaries than in the alveoli; vise versa with CO2)
Primary Respiratory Drive
when levels of CO2 become too high or low, the brain (stem) adjusts breathing accordingly; low O levels in the blood is the drive to stimulate breathing
Medulla Oblongata
detects CO2 and O levels in the bloodstream and determines what changes need to happen in the body; can send nerve impulses to the heart and diaphragm
the body's tissues and cells are not receiving enough oxygen; pts can die quickly if this condition is not reserved
decreased amount of oxygen in arterial blood (untreated and it will lead to hypoxia)
an absence of oxygen to any part of the body
S&S of Hypoxia
---high HR (tachycardia) (early sign)
---cyanosis (late sign)
---dyspnea; pts may not be able to talk in complete sentences
S&S of inadequate breathing
---resp rate less than 12 or more than 20 breaths per min
---irregular rhythm
---pale, cyanotic, cool or moist (clammy) skin
Cheyne Stokes
often seen in patients who have had a stroke with head injuries; characterized by irregular breathing pattern, increasing rate and depth, followed by a period of apnea
Best position to monitor airway
supine ; lying down
Head-tilt chin lift
for non-critical patients; one hand on forehead and two fingers under chin to lift the head
Jaw thrust maneuver
for trauma pts with suspected head or spinal injury; fingers on each side of jaw grasping it and moving it upward; use head tilt chin lift if jaw thrust does not work on a trauma pt
Oropharyngeal airway
keep tongue from blocking upper airway; easy to suction pharynx if necessary; used with BVM's; used ONLY on pts who are unconscious and without gag reflex ; apneic
Nasopharyngeal airway
better tolerated with pts with gag reflex; never force into place ( can cause nasal bleed);

Contraindications: severe head injury with blood draining from nose; any injuries to the nose
Adults- no more than 15 seconds
children- 10 seconds
infants- 5 seconds
Recovery position/ Lateral Recumbant
used to help maintain a clear airway in a pt that is not injured and is breathing on their own ; prevents aspiration

Mechanisms of Heat Loss
-- conduction
direct contact with source or object (Ex: warm hand touches metal or ice)
heat is transferred to circulating air (shivering)
the transfer of heat is often between bodies, which may be separated spatially
body heat is lost through exhalation and cold air is taken in by inhalation
when bodies temp drops below normal; core temp falls below 95 degrees (35 degrees celcius ); develops rapidly or gradually; pts with burns, infection, spinal cord injury, hypoglycemia are more prone to this
Mild Hypothermia
(90-95 degrees); pt is usually alert and shivering in an attempt to generate heat; pulse rate and resp. are usually rapid; skin may be flushed (red) but may turn to pale due to bodies constriction of blood vessels at the skin to retain heat, than cyanotic; may have blue lips or fingertips
Severe Hypothermia
(less than 90 degrees); shivering stops and muscular activity decreases; pt becomes lethargic; LOC decreases; BP drops; poor condition and memory loss; reduced or complete loss of sensation of touch, mood changes, and impaired judgment; resp slow; @ 80 degrees or less, all cardiovascular activity may cease; pupil reaction is slow
Management of Cold Exposure

death from suffocation after submersion in water; pt swallows a lot of water, causing them to accumulate a laryngospasm
a brief spasm of the vocal cords that temporarily makes it difficult to speak or breathe. The onset of vocal cord spasms is usually sudden, and the breathing difficulty can be alarming.
Near Drowning
survival, at least temporarily (24 hours) after suffocation in water
Diving reflex
This causes bradycardia and slowing of the metabolic rate and peripheral vasoconstriction. Blood is diverted from the limbs and all organs but the heart and the brain, creating a heart-brain circuit and allowing the mammal to conserve oxygen. In humans, the mammalian diving reflex is not induced when limbs are introduced to cold water.

Senses changes in geriatric pts
pupils lose ability to adjust to light, cataracts (clouding of the lens; vision is cloudy), hearing problems, slowing of peripheral nervous system (slow to react when touching something hot)
Resp system changes in geriatric pts
alveoli enlarged and elastic decreases making it harder to breath; loses ability to contract after inflation, decrease in exchange of oxygen and CO2, low pulse oximetry readings because the sensitivity of chemoreceptors decreases with age; more prone to infections
Cardiovascular system changes in geriatric pts
decreased ability to increase contractions and vessels (decreased ability for the body to compensate for simple injuries), decreased ability of body to respond to keep homeostasis in changed environments; atherosclerosis and arteriosclerosis (hardening and stiffening of the arteries , causing higher BP as you get older)
Renal system changes in geriatric pts
kidney function declines because of the decrease in the number of nephrons , electrolyte disturbances occur because of the low ability of the body to filter it out causes AMS
Nervous system changes in geriatric pts
number of brain cells decrease, brain loses weight, decrease in reflex time and psychomotor skills; IMPORTANT TO COMPARE THESE PTS WITH CURRENT STATUS AND NORMAL STATUS
Musculoskeletal changes in geriatric pts
fractures are more likely because of the decrease in bone density (osteoporosis); hunch back making transport of these pts more challenging
GI system changes in geriatric pts
harder to chew and digest food; slowing of GI tract; difficult to filter our medications and alcohol
