Warming
Tactile stimulation
56
Systolic vs diastolic pressure
Systolic = left ventricle contracts (Top #)
Diastolic = left ventricle relaxes (Bottom #)
57
What happens when the diaphragm distends?
Ilues causes anything eaten to not pass through the stomach through the bowel. The only way to empty is by emesis. Vomiting and nausea is most commonly associated with distention
****Peritonitis causes ilues (paralysis of muscular contractions) this prevents the traveling of materials through the intestine. This creates gas and feces buildup causing distention.
58
How does our skin regulate temperature?
The production of sweat, its evaporated from skins surface helping regulate temp.
*** High temp = BV in dermis dilate ⬆️ blood flow to skin allows heat to dissipate
59
What are the effects of Chlorine & Phosgene on the body?
They are both Pulmonary Agents(Choking Agents)
(CL) Upper airway irritation(Hoarseness and stridor), shortness of breath, tightness in chest, gasping& coughing
Phosgene: delayed onset of symptoms, smells like freshly cut grass, Nausea, chest tightness, severe cough and dyspnea on exertion.

V5- Lateral to V4 (anterior auxiliary line)
V6- Lateral to V5 (midaxillary line)
RA(Right Arm), LA(Left Arm), LL(Left Leg), RL(right leg)
61
What is an air embolism?
When air enters circulatory system through a vein this leads to the heart and can cause cardiac arrest if enough air enters. Happens mostly through penetrating injuries
***Also caused by SCUBA diving- diver holds breath on rapid ascent pressure in lungs increases causing alveoli to rupture this alowes air into bloodstream creating bubbles of air in the vessels.

74
Hyperventilation definition and Hyperventilation Syndrome
Rapid, deep breathing that lower the blood CO2 level. Can be causes by high blood sugar, overdose on aspirin or severe infection (Body trying to stay alive,compensating for acidosis)
The syndrome occurs in absence of physical problem. 40 Shallow breaths/min or as low as 20 very deep breaths/min. Associated with panic attacks (gets rid of too much CO2, causing Alkalosis[excess base])

Sulfur Mustard (H)
AKA - Mustard gas
Brown/yellowish oily substance, attacks bone marrow depleting white blood cells(can’t fight infection)
Absorbed into skin/mucous membranes(within seconds) starting an irreversible process of damage to skin(1 to 2 min). It mutates, damages and changes the structures of cells
S&S - Reddening of skin that turns into large blisters, upper and lower airway compromise (4 to 6 hours after exposure)
77

87
S&S of intra-abdominal bleeding
Acute abdominal pain, distention from fluid buildup = Blood in peritoneal cavity
Will initially appear as abrasions because it takes hours for hematoma/contusions to become visible, N&V most common
Hollow organ blunt trauma = delayed S&S (peritonitis or infection of Abdominal wall)
