early stages of shock, while the body can still compensate for blood loss
71
Signs and Symptoms of compensated shock
```
Agitation
Anxiety
Restlessness
Feeling of impending doom
Altered mental status
Weak, rapid (thready) or absent pulse
Clammy (pale, cool, moist) skin
Pallor, with cyanosis about the lips
Shallow, rapid breathing
Air hunger (shortness of breath) especially if there is a chest injury
Nausea or vomiting
Capillary refill of longer than 2 seconds in infants and children
Marked thirst
Narrowing pulse pressure
```
72
Decompensated Shock
late stages of shock, when blood pressure is falling
73
Signs and Symptoms of decompensated shock
Falling blood pressure (systolic blood pressure of 90 mm Hg or lower in an adult)
Labored or irregular breathing
Ashen, mottled, or cyanotic skin
Thready or absent peripheral pulses
Dull eyes, dilated pupils
Poor urinary output
74
Shock(hypoperfusion)
describes a state of collapse and failure of the cardiovascular system (when the circulation of blood in the body becomes inadequate, the oxygen and nutrient needs of the cells cannot be met).
75
Obstructive Shock
caused by a mechanical obstruction which prevents an adequate volume of blood to fill the heart chambers. Three of the most common examples of obstructive shock are cardiac tamponade, tension pneumothorax, pulmonary embolism
76
Cardiac tamponade
compression of the heart as the result of buildup of blood or other fluid in the pericardial sac, leading to decreased cardiac output
77
Tension pneumothorax
is the accumulation of air in the pleural space, which eventually compresses the heart and great vessels
78
Pulmonary embolism-
a blood clot that breaks off from a large vein and travels to the blood vessels of the lung, causing obstruction of blood flow
79
Distributive Shock
a condition that occurs when there is a widespread dilation of the small arteriales, small venules, or both. As a result, the circulating blood volume pools in the extended vascular beds and tissue perfusion decreases. The four most common types of distributive shock are septic shock, neurogenic shock, anaphylactic shock, and psychogenic shock.
80
septic shock
shock caused by severe infection, usually a bacterial infection.
81
neurogenic Shock
circulatory failure caused by paralysis of the nerves that control the size of the blood vessels, leading to widespread dilation; seen in patients with spinal cord injuries.
82
Anaphylactic shock
severe shock caused by an allergic reaction
83
sensitization
becoming sensitive to a substance that did not initially cause a reaction.
84
Psychogenic Shock
shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope)
85
Hypovolemic Shock
shock caused by fluid or blood loss. Result of an inadequate amount of fluid or volume in the circulatory system. There are hemorrhagic and non-hemorrhagic cause of hypovolemic Shock.
86
dehydration
loss of water or fluid from body tissues, can cause or aggravate shock.
87
Cardiogenic Shock
caused by inadequate function of the heart, or pump failure (circulation of blood throughout the vascular system requires the constant pumping action of a normal and vigorous heart muscle).
88
Edema
the presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area.
89
Preload
the pressure that is accumulated inside of the ventricles as the heart relaxes, letting blood in to fill the chambers. (Precontraction pressure)
90
Afterload
the resistance against the heart as it contracts for it to overcome and eject the blood out through the aorta and pulmonary arteries.
91
ACS
(Acute Coronary Syndrome)
| (Myocardial Infarction)- “Heart attack”
92
Chest pain (Men)
- “L” arm, shoulder, jaw
- Dyspnea “difficulty breathing”
- Pale, cool, diaphoretic
- N/V/D
93
AED
be aware of surface that patient is lying on.
- what is the age of patient
- does patient have medication patch
- does patient have pacemaker
If patient is unresponsive and does not have a pulse apply AED and push analyze
If resuscitation is possible ROSC Monitor for spontaneous respirations provide 02 via BVM at 10-12 breaths/min assess bp if ALS is not on scene being transport
94
L-Sided vs R-Sided Heart Failure
| Right-Sided
Back-ups in the area that collects “used” blood
95
L-Sided vs R-Sided Heart Failure
| Left-Sided
The left ventricle can’t pump blood out to the body as fast as it returns from the lungs which begins to back up in the blood vessels of the lungs (Pulmonary Edema)
96
Congestive heart failure
Fluid backs up into the lungs and tissues
97
Arrhythmias leading to cardiac arrest
- Ventricular Fibrillation (V-fib) - Disorganized, ineffective quivering of the ventricles, no blood is being pumped through the body
- Ventricular Tachycardia (V-tach) - Rapid heart rhythm that doesn’t allow the chambers to refill
98
Pertinent Negatives
-Negative findings that indicate no care or intervention
Finding out the signs and symptoms that the patient does not have
-Helpful in identifying a patient's problem and choosing an appropriate treatment
99
Pulse Oximetry
An assessment tool that measures oxygen saturation of hemoglobin in the capillary beds
Oxygen saturation is the measure of the % of hemoglobin molecules that are bound in arterial blood
