Over the apex of the heart (heard with stethoscope) | Most accurate for cardiovascular assessment of children and infants
33
Conditions that increase resting heart rate
``` Activity Fever Stress Hyperthyroidism Anemia Stimulants Asthma Medications Diet pills Various forms of heart disease Heart medications Fitness programs with aerobic exercise ```
34
A weak pulse sign
Maybe sign of a problem with the hearts ability to pump as much blood as the body needs Can be a sign of shock or a circulation problem such a as partially blocked vessel or narrowed blood vessel
35
A weak or absent pulse symptoms
Vessels feels soft when checking the pulse | A hard blocked vessel suggests hardening of the arteries
36
How to take a pulse
Place index and middle finger over pulse site and count beats for a minute
37
Average pulse rates
Adults - b/w 60 and 100 beats per minute
38
Recording pulse rates
Use p for the abbreviation
39
what is Respiration
Exchanges oxygen and carbon dioxide b/w the external environment and the blood circulating in the body
40
One full expiration is
1 inspiration and 1 expiration
41
Average respiration rates
Adult - 12 to 20 beats | Infant - 30 to 60 beats
42
Observing respiration
Rate - how many breaths per minute Depth - shallow or deep Quality - supplying the O2 needs of the patient Pattern - rapid or staggered
43
Respirations fewer than 10/min may result in
Cyanosis Apprehension Restlessness Change in level of consciousness
44
Factors that affect respiration
``` Medication Illness or pathologies Exercise Age Emotion ```
45
Bradypnea
Slow breath with fewer than 12 breaths per minute
46
Dyspnea
Difficulty in breathing, shortness of breath, using more than the normal effort to breath, abnormal respiratory rate
47

48
Tachypnea
Rapid breath in in excess of 20 breaths per minute
49
Body temperature
The physiological balance b/w heat produced in the body and heat lost to the environment
50
Pyrexia
Fever - a patient whose body temp is elevated above normal limits
51
Hypothermia
A patient whose body temp is below normal limits
52
Factors that affect body temp
Environment - slightly hotter in hot environments Time of day - lower in the morning Infection/disease/injury Age - decreases slightly with age Emotional status - increases with stress Menstrual cycle - higher during ovulation Physical activity - slight increase but plateaus Site of measurement - oral vs rectal
53
Normal oral temperate range for adults

54
Oral temperature
Not always appropriate Depends on patient and conditions (infants vs adults) Takes 1-2 minutes
55
Auxiliary temp site
Patient perferred but it's slower and less accurate Safest method Takes 1-2 mins Non-invasive Commonly used for infants Electronic or disposable or glass thermometer with blunt tip maybe used
56
Rectal temperature site
Accurate (most reliable) and faster but has patient contraindications Use thermometer with blunt tip Least perferred method by the patient Takes 1-2 minutes
57
Tympanic and temporal artery temp site
Common for children and confused patients | Takes 2-3 seconds
58
How to chart temperature
``` Oral - 0 Axillary - A Tympanic -T Rectal - R It is important to include the time in which the temp was taken on the chart ```
59
Types of thermometers
Digital/electric - used to take oral, axillary, and rectal Tympanic Temporal artery Disposable - used for children, ICU and isolation patients
60
Importance of patient info
Patient history must support the exam requested Avoids the incorrect exam being taken Minimize the amount of radiation the patient recieves Efficiently uses the equipment contrast ect.. Involved in the exam
61
Definition of Shock
General term used to describe a failure or circulation in which blood pressure is inadequate to support oxygen perfusion of vital tissues and unable to remove the by products of metabolism Potentially fatal condition
62
Different types of shock
``` Hypovolemic Septic Neurogenic Cardiogenic Allergic or anaphylactic ```
63
What is Hypovolemic shock and is caused by
Occurs when a large amount of blood or plasma has been lost, leaving an insufficient amount of fluid in the circulatory system - external hemorrhage - lacerations - plasma loss from burns - internal bleeding from trauma or perforated gastric ulcer - severe dehydration, vomiting, diarrhea, or extreme diuresis
64
Treatment for Hypovolemic shock
Fluid replacement for low volume shock (saline or blood) Administration of oxygen Medication to promote vasoconstriction
65
What is septic shock and the cause of it
Massive infection occurs in the body Gram negative bacteria is the most common causative organisms to cause septic shock Gram positive bacteria and viruses can be the cause, the body begins immune response by releasing chemicals that increase capillary permeability and vasodilation Has a first phase and second phase
66
Signs and symptoms of first phase of septic shock
Hot, dry, flushed skin Increase in heart rate and respiratory rate Fever but possibly not in the elderly patient Nausea, vomiting, and diarrhea Normal to excessive urine output Possible confusion
67
Signs and symptoms of second phase of septic shock
``` Cool, pale skin Normal temperature Drop in BP Rapid heart rate and respiratory rate Anuria Seizures and organ failure ```
68
What is neurogenic shock and causes of it
Failure of arterial resistance, causing a pooling of blood in peripheral vessels Injury to the nervous system and reaction to meds can cause this Pt's with head and spinal injuries are the most common with this type of shock
69
Signs and symptoms of neurogenic shock
Warm, dry skin Bradycardia Hypotension Diminishing peripheral pulses, cool extremities *monitor pulse, respiration and BP every 5 min. With head/spinal injuries monitor BP more closely looking for changes*
70
what is Cardiogenic shock and what causes it
Results from cardiac failure of heart to pump an adequate amount of blood to the vital organs The onset may occur over a period of it may be sudden Most vulnerable pt's include those w/ myocardial infarction, dysrhythmias or other cardiac pathologies
71
Cardiogenic Shock manifestations
``` Complaint of chest pain that may radiate to jaws and arms Dizziness and respiratory distress Cyanosis Restlessness and anxiety Rapid change in LOC Pulse that may be irregular and slow; may have tachycardia and tachypnea Decreasing BP Decreasing urinary output Cool, clammy skin ```
72
Allergic or Anaphylactic Shock
Usually the more abrupt the onset of anaphylaxis the more severe the reaction will be (large bolus injection of contrast media) Anaphylactic shock is the result of an exaggerated hypersensitivity reaction. Occurs when histamine and bradykinin are released causing widespread vasodilation which results in peripheral pooling of blood accompanied by contraction of nonvascular smooth muscles, particularly the smooth muscles of the respiratory tract
73
Mild to moderate signs/symptoms of allergic reaction
``` Itchy skin Urticaria Nasal congestion, watery eyes, sneezing Coughing with possible laryngeal swelling Peripheral tingling Tachycardia or bradycardia Hypotension Feeling of fullness or tightness of chest, mouth, or throat Feeling of anxiety or nervousness ```
74
Serve allergic shock signs/symptoms
``` Abrupt onset of symptoms Bradycardia (<50beats/min) Hypotension (decreases in BP) Severe dyspnea Cardiac arrhythmias Laryngeal swelling Possible convulsions/seizures Loss of consciousness Respiratory arrest or cardiac arrest ```
75
Response to anaphylactic shock
Do not leave pt alone Stop any infusion and maintain the IV line Notify rad or ER dr Call code team if symptoms are severe Place pt in semi fowler or sitting positions to facilitate respiration Monitor pulse, BP, respiration every 5 min till code team arrives Prepare O2 and intravenous fluids and drug box Always keep track of the time and sequence of events for documentation
76
Ways to prevent shock
Avoid sudden changes in temp - keep pt warm Reduce pain and stress - handle pt gently and with care Reduce anxiety - work in calm, confident manner, reassure the pt and listen to their concerns and answer questions
77
Tech's responsibility if the pt is going into shock
Stop procedure and assist the pt Elevate feet to increase blood flow to brain Obtain help. If in doubt call a code Check BP and assist the dyspenic pt with O2 Be ready to assist code team and document events
78
Physical Evaluation Includes assessment of
Skin colour Skin temperature Breathing LOC
79
Skin Colour Assessment
Easiest way to recognize change Look for cyanosis (bluish colour in the skin) Caused by lack of O2 in the tissues Easily seen on mucous membranes such as lips and lining of mouth If pt look pale and anxious and states they do not not feel well, tech should not leave the pt
80
Skin Temperature Assessment
Contact thought touch also allows ongoing physical observation Actually ill pt who is in pain will likely be pale, cool and diaphoretic Hot dry skin may indicate fever while moist skin may only be a response to the environment
81
Breathing Assessment
Changes may be signal onset of serious distress Normal breathing is quiet and calm Abnormal breathing is audible, wheezing, gasping or coughing Sudden onset of rapid, shallow breathing is usually first sign of respiratory distress
82
LOC assessment
Is noted to be establish as the pt's baseline - alert and responsive - drowsy but responsive - unconscious but reactive to painful stimuli - comatose
83
When communicating with a pt who is drowsy it is important to remember
- they can't be relied upon to remember instructions | - they aren't responsible for their actions or answers
84
Glasgow Coma scale
Used to assess LOC and reaction to stimuli in a neurologically impaired pt based on performance - eye opening = score of 1-4 - verbal response = score 1-5 - motor response = score 1-6 The highest possible score is 15, lower scores predict poorer outcomes
85
Changes in the Glasgow coma scale could be caused by
Increase in intracranial pressure (ICP) | The is change can be life threatening and physician must be notified immediately
86
Signs of Increased intracranial pressure
Pt become irritable Pt becomes lethargic Pt's pulse slows down and their rate of respiration decreases
87
Pt physical environment includes
``` Temp Humidity Lighting Ventilation Colour of surroundings Noise ```
