30
symptoms of emphysema
dyspnea, wheezing, chronic cough, sputum, symptoms worsen overtime
30
what is panlobular emphysema
uniform enlargement of airspaces aka the alveoli throughout the entire lung lobule
31
what is centrilobular emphysema
primarily affects the upper lobes of the lungs and is associate with smoking
32
what is a bullectomy
procedure to remove abnormally large air spaces or air filled sacs that develop within the lung tissue r/t emphysema or COPD
33
what is lung volume reduction surgery
treat severe emphysema traditionally performed by making incision in chest to access the lungs, damaged areas of lung tissue are removed. aims to improve lung function by reducing hyperinflation and improve respiratory mechanics
34
what is chest physiotherapy
set of techniques aimed at improving lung function and clearing mucus or secretions from airways chest percussion chest vibration postural drainge breathing exercises
35
complications of oxygen therapy
oxygen toxicity absorption atelectasis fire hazard drying of mucus membranes oxygen induced hypoventilation
36
low flow oxygen therapy
flow rate of oxy is lower than the patient's peak inspiratory flow rate. continuous or intermittent supply of oxy 1. nasal cannula 2. simple face mask patients may have COPD, congestive heart failure, pneumona
37
the flow rate of oxygen delivered via nasal cannula is
1 to 6 liters per minute
38
the flow rate of oxygen via face mask is
5 to 10 liters per minute the mask delivers a higher concentration of oxygen compared to nasal cannula
39
nursing responsiblity r/t oxygen therapy
monitored closely for signs of oxygen toxicity, hypoventilation, etc
40
high flow oxygen therapy is
therapy that delivers a high flow rate of heated and humidified oxygen to patient with respiratory insufficiency. unlike low flow which delivers a variable oxygen concentration depending on the patient's breathing pattern, high flow oxy therapy delivers a constant and controlled concentration of oxygen, regardless of patient's inspiratory flow rate typically delivered through a "high-flow nasal cannula"
41
high-flow oxygen therapy flow raes
20 to 60 liters per minute or higher
42
heated and humidified oxygen
the oxygen delivered through a high flow nasal cannula is heated and humidified to minimize drying and patient comfort
43
what is a non-invasive positive pressure ventilation
type of ventilatory support that delivers mechanical ventilation to the lungs without the need for invasive procedures. it is typically delivered thru a mask or nasal interface providing continuous positive airway pressure CPAP or BIPAP to support breathing
44

52
trach - preventing aspiration
positioning, food/liquid consistency, monitoring
53
54
what is the hallmark characteristic of bronchiectasis
Ectasis" is a term derived from the Greek word "ektasis," which means expansion or dilation. In medical terminology, it is used to describe the abnormal enlargement or dilation of a tubular structure in the body, such as blood vessels or hollow organ thus, permanent abnormal dilation of medium-sized bronchi
55
why doses it matter if the bronchi are over dilated?
inflammatory changes weaken the bronchial wall, therefor airway damage, the walls can develop colonies of microorganisims leading to infection when the walls of the bronchi are injured, the mucociliary mechanisim is damaged (that escalator thing) and again this leads to infection
56
the main points of bronchiectasis
the bronchi are over dilated leading to mucus/bacteria/infection accumulation that is nearly impossible to cough out there is no cure
57
cystic fibrosis is a type of
bronchiectasis
58
main points of cystic fibrosis
-genetic disease - increased abnormally thick, sticky mucus production - GI, pancreas issues - recurrent resp infections, persistent cough -
59
what is the gold standard for diagnosing CF
the sweat chloride test
60
main points of asthma patho
- reversible airflow obstruction, usually temporary attacks - chronic inflammatory disease - bronchoconstriction, mucus, edema - bronchial hyperreactivity
61
what are the risk factors for asthma
genetics and environment
62
what is "silent chest"
if the patient with asthma has been wheezing, followed by sudden absence of a wheeze and the patient is struggling to breathe this is a life threatening emergency
63
drug therapy for asthma can be complex. usually divided in to two types what are they
1. short term "rescue" inhaler 2. preferred reliever agents
64
where as asthma is reversible and temporary, COPD is progressive and _______ airflow limitation
persistent
65
copd patho main points
- chronic inflammation of lungs - airflow limitation not fully reversible during forced exhalation - main cause is the loss of elastic recoil and airflow obstruction from mucus hypersecretion, mucosal edema, and bronchospasm
66
true or false: status asthmaticus is a mild form of asthma
false! this is a life threatening emergency, most extreme form of asthma s/s hypoxia, hypercapnia patient is unresponsive to treatment with bronchodilators and corticosteroids patient will most likely need immediate mechanical ventilation
67
main points chronic bronchitits
- inflammation of bronchi caused by chronic exposure to irritants such as cigarette smoke - constant irritants produce mucus - bronchial walls become thickened, and lumen narrow -irreversible tissue damage
68
main points emphysema
-destruction of alveoli, lungs loose elasticity and alveoli hyperinflate - overstretching and enlargement of alveoli into bullae
69
there are 2 types of emphysema what are panlobular and centrilobular what is the difference
panlobular - uniform destruction of functional unit of the resp system where gas exchange occurs; bronchioles, alveolar ducts and alveoli centrilobular - primarily affects the upper lobes of the lungs
70
what is a bullectomy
1 or more very large bullae are removed. this help WOB.
71
what is lung volume reduction
surgery that reduces the size of the lungs by removing some of the diseased tissue so that remaining healthy tissue can thrive
72
oxygen therapy is a common treatment for
hypoxemia and hypoxia
73
we classify O2 delivery systems as low flow or high flow. Low flow delivery devices are appropriate for patients who are ____,____,_____
awake, alert, and spontaneously breathing with a stable intact respiratory drive
74
high flow o2 delivery devices differ because they deliver a _____O2 concentration independent of the patients respiratory rate or pattern
fixed
75
high flow systems provide O2 that ____ or _____ the patient's resp demand
meet, exceed
76
patients requiring high flow therapy are also awake, alert, and spontaneously breathing but have _____o2 requirements that low flow devices cannot meet
higher
77
examples of low flow devices include
nasal prongs, simple masks, non rebreather maskse
78
examples of high flow masks include
venturi mask and high flow nasal cannula
79
we all know what a god damn nasal cannula (low flow) is but tell me about it anyway
most commonly used used for patients requiring low o2 concentrations achieves o2 concentrations of 1 L/min to 6 L/min
80
Okay, main points of partial and non-rebreather masks
used for short term therapy for patients with higher O2 needs achieves o2 concentrations of 10-15 L/min o2 flows into reservoir bag and mask during inhalation bag allows patient to rebreathe 1/3 of oxygen rich air - vents stay open on mask
81
high flow venturi mask main points
- mask can deliver precise, high flow rates of o2 low, constant o2 concentrations, used for COPD patients
82
true or false: smoking is recommended around o2 cannisters
false that shit will blow up
83
what the hell is O2 toxicity
prolonged exposure to a high level of o2, can result in severe inflammatory response which can lead to pulmonary edema, shunting of blood, hypoxemia, pulmonary edema
84
the alveoli contain many different gases, including o2, co2, and nitrogen. Nitrogen helps maintain the size, shape and structure of the alveolus. if the brochial tubes become obstructed (mucus) the exchange of co2 and o2 cant occur. nitrogen will eventually move out of the alveolus and into the bloodstream this is called "nitrogen washout" as a result, the alveoulus collapses, and absorption atelectasis occurs. what does this result in?
absorption atelectasis
85
______ helps maintain the size, shape, and structure of the alveolus
nitrogen
86
okay we are almost there, clean the o2 device. why would we clean it?
because a bunch of bacteria will grow on it and lead to infection
87
okay, chemo receptors control the drive to breathe. They respond to co2 and o2 concentrations in the blood. as we know, normally an increase in co2 in the blood is a major stimulant of the resp center however, patient with COPD develop a TOLERANCE for higher co2 levels. as a result the resp loses it sensitivitey to high co2 levels. For these patients a major drive to breathe is hypoxemia (low oxygen in the blood). If we are giving a bunch of oxygen and its getting in the patient blood then we have some problems. as a result, there is a concern about the dangers of giving o2 to a copd patient and reducing their stimulus or drive to breathe what is this called
oxygen induced hypoventilation or co2 narcosis
88
co2 retention is also known as
hypercapnia
89
what is hypercapnia how can it happen
abnormally high level of CO2 in the blood, the body is unable to eliminate co2 efficiently leading to its accumulation in the blood stream COPD, CNS disorders, meds, severe anemia
90
nasal cannula flow rate (low flow)
1 L/min to 6 L/min
91
simple face mask flow rate (low flow)
6 -12 L/min
92
partial rebreather flow rate (low flow)
10 to 15 L/min
93
non rebreather flow rate low flow
10-15 L/min
94
tell me again about a high flow venturi mask. who would find it beneficial?
mask can deliver precise high flow rate of o2 low, constant o2 concentration for copd patients can be humidified its uncomfortable
95
tell me about a tracheostomy collar, how does it work, who would use this?
collar attaches to neck, delivers humidity and o2, needs to be cleaned q4hr and prn to prevent aspirtation
96
high flow nasal cannula flow rate
up to 60L/min!
97
the endotracheal tube is a long flexible plastic tube that secures a patients airway when they need mechanical ventilation. An ET consists of a standard adaptor, cuff, pilot balloon along the length of the tube the cuff pressure needs to be checked every 8 hours what should the pressure be?
15-22 mmHG
98
99
which condition may develop if severe pneumonia is left untreated? a. atelectasis b. hemoptysis c. bronchiectasis d. chronic bronchitis
c. bronchiectasis
100
_______ is a complication of asthma due to hyperinflation of the lungs and increased dead space
atelectasis
101
what is the primary cause of brochiectasis
untreated or delayed treatment of bacterial lung infections
