Q

How does gas exchange happen and where

A

occurs in the alveoli, O2 goes to the blood which carries O2 to the body, and CO2 is brought back to the alveoli to be breathed out

25
Factors that influence oxygenation (9)
stress, allergies, air quality, altitude, temperature, pregnancy, obesity, exercise, smoking
26
How do allergies effect the respiratory system
cause inflammation to the nasal passage
27
How does air quality affect the respiratory system
trigger respiratory problems
28
How does the temperature affect the respiratory system
cold temperatures require the air to be moistened
29
How does pregnancy affect the respiratory system
increase the need of oxygen
30
How does exercise affect the respiratory system
increase metabolic demand
31
How does smoking affect the respiratory system
chemicals block airways and kill hairs, and decrease elasticity
32
What signs do the face give about respiratory status (4)
breathing effort and quality, pursed lips (abnormal), flared nostrils (abnormal), grunting (abnormal)
33
What signs does body position give about respiratory status (2)
client should be sitting up relaxed, tripod position (abnormal)
34
What signs do skin and nails give about respiratory status (2)
cyanosis is a sign of hypoxia (abnormal), clubbing indicates long term hypoxia (abnormal)
35
What signs does the chest give about respiratory status (4)
Breathing appears effortless, retractions (abnormal), accessory muscle use (abnormal), 1:2 anteroposterior to lateral ratio (equal in infants)
36
What signs does the thorax give about respiratory status (4)
scapula should be symmetric, shoulders at equal positions, straight spine, midline and straight sternum
37
Scoliosis
spine deviates laterally
38
Kyphosis
increased curve of the thoracic spine
39
What signs does palpation give about respiratory status (2)
lumps/masses (abnormal), pain/tenderness (abnormal)
40
Crepitus
air trapped under skin, feels like crackling when you touch skin
41
Fremitus
vibration that can be felt across the lung field
42
What does increase vibration in the lungs indicate
extra fluid
43
How to measure expansion of the lungs
place hand on anterior chest wall with thumbs pointed towards xiphoid process/place hands on posterior chest wall at T9 or T10 Thumbs should move apart symmetrically 5-10 cm
44
What do you percuss when you percuss the lungs and where
tone over intercostal spaces
45
Resonance
the tone heard over normal lung tissue
46
How do you auscultate the lungs
instruct client to breathe slowly through their mouth, move stethoscope from side to side, compare sounds bilaterally, listen for one full respiration in each spot
47
Developmental variations in infants (6)
Immature lower airway/nervous system/immune system, narrow airways, breathe out of nose only until 6 months, diaphragmatic breathers (check rr in stomach until 1), normal rr=30-53, chest sound is smooth and round
48
Developmental variations in children (4)
upper respiratory infections are common, asthma presents, short/small airways, drowning in small amounts of water
49
Developmental variations in school-aged (3)
mature heart/lungs/circulatory system, URIs resolve easily, asthma
50
Developmental variations in older adults (7)
reduced lung expansion/less alveolar inflation, difficulty clearing airways because of weak muscles, declining immune response, chemoreceptors respond more slowly, kyphosis is common, loss of skeletal/accessory muscles and elasticity, calcification of cartilage,
51
What are the normal lung sounds (3)
bronchial, bronchovesicular, vesicular
52
Describe bronchial lung sounds
high pitched and harsh, short during inspiration and long during expiration
53
Describe bronchovesicular lung sounds
moderate pitch and amplitude, same length during both inspiration and expiration (1:1)
54
Describe vesicular lung sounds
low, breezy, and soft, expiration is shorter than inspiration, heard best on bases and periphery of lungs
55
What are the adventitious breath sounds (3)
crackles, wheezing, pleural rub
56
Describe crackle lung sounds
caused by fluid in small airways or atelectasis, intermittent popping sounds
57
Describe wheezing lung sounds
caused by air moving through narrowed airways, heard continuously on inspiration or expiration sounds like a whale
58
Describe pleural rub lung sounds
low pitched dry grating sound, caused by restricted air flow or due to body type sounds like rubber rubbing together
59
What is a normal rr rate
12-20 breaths per minute
60
What is normal rr rate called
eupnea
61
What is a normal oxygen saturation
95-100
62
Bradypnea
slow respirations, <10 per minute
63
Tachypnea
fast respirations >24 per minute
64
Apnea
absence of breathing
65
hypoxia
low oxygen in tissue
66
hypoxemia
low oxygen in blood
67
tympany
high, drum like sound common over the stomach
68
dullness
present over fluid or solid tissue
69
flatness
heard over muscle mass or bones
70
hyperresonance
overly-resonant sounds, can indicate trapped air
71
What are some nursing interventions to support and maintain adequate oxygenation
end smoking, vaccinations, avoid pollutant, exercise weekly
72
What does hyperventilation cause
a decrease of CO2 in the body
