91

Hazards of supplemental oxygen are 

combustion, oxygen toxicity

92

Types of contraindications

absolute, relative

93

Types of Side effects

unintended effects, untoward effects

94

3 parts of cardiovascular system- heart, blood vessels or arteries, the blood

Perfusion triangle

95

peak arterial pressure

Systolic

96

pressure in the arteries while the heart rest between heartbeats

Diastolic

97

cardiogenic shock, obstructive shock

Pump failure

98

distributive shock causes 

Poor vessel function

99

Cardiogenic shock causes

caused by inadequate function of the heart, major effect is the build up of blood into lungs

100

presence of abnormally large amounts of fluid between cells in body tissues.

Edema

101

caused by mechanical obstruction that prevents an adequate volume of blood from filling the chambers

Obstructive Shock

102

caused by mechanical obstruction that prevents an adequate volume of blood from filling the chambers

Obstructive Shock

103

Common examples of obstructive shock

cardiac tamponade, tension pneumothorax, pulmonary embolism

104

collection of fluid between the pericardial sac and the myocardium(pericardial effusion) becomes large enough to prevent ventricles from filling with blood. - caused by blunt or penetrating trauma, signs and symptoms are referred to as beck triad

Cardiac tamponade

105

caused by damage to lung, the air normally held within the lung escapes into the chest cavity. - the lung and air applies pressure to the organs, including the heart and great vessels

Tension pneumothorax

106

a blood clot that blocks the flow of blood through pulmonary vessels. -  can result in complete backup of blood in the right ventricle - leads to catastrophic obstructive shock and complete pump failure

Pulmonary embolism

107

results from widespread dilation of small arterioles, small venules, or both, the circulating blood volume pools in the expanded vascular beds, tissue perfusion decreases

Distributive shock

108

results from severe infections in which toxins are generated by bacteria or by infected body tissue ; widespread dilation of vessels, in combination with plasma loss through the vessel walls, result in shock

Septic shock

109

shock that is usually the result of high spinal cord injury.

Neurogenic shock

110

Causes of neurogenic shock

brain conditions, tumors, pressure on the spinal cord, spina bifida

111

caused by sudden reaction of the nervous system, produces temporary, generalized vascular dilation, results in fainting ( syncope)

Psychogenic shock

112

result of an inadequate amount of fluid or volume in the circulatory system

Hypovolemic shock

113

early stage when the body can still compensate for blood loss

Compensated shock

114

hypovolemic shock  causes

Low fluid volume

115

late stage when blood pressure is falling

Decompensated shock

116

Conditions to expect shock

multiple severe fractures, abdominal or chest injury, spinal injury, a severe infection, a major heart attack, anaphylaxics

117

Treatment for cardiac tamponade

apply high-flow oxygen; surgery is the only definitive treatment

118

Treatment for tension pneumothorax

apply high- flow oxygen to prevent hypoxia; chest decompression

119

Treatment for septic shock

high flow oxygen, blankets to conserve body heat

120

Treatment for anaphylactic shock

adminsiter epinephrine, provide high flow oxygen and ventilatory assistance en route
