the __ is the site of the cough reflex
carina
patients who need nasotracheal suctioning will cough when the nasotracheal
tubing reaches the
carina (approximately the 2nd rib space)
this signals that tubing is near the lungs and if the cough is effective suctioning may
begin
during CPR hand are placed above the __ process to avoid breaking it off form
the sternum and causing complications such as pneumothorax, hemothorax, or
liver injury
xiphoid
the left lung has __ lobes. the right lung has __ lobes
two, three
the __ refers to the very bottom of the lung fields, the __ is the very top opposite
of the labeling of the heart
base, apex
lungs are auscultated from
apex to base
the apex of each lung rises above the clavicle where lungs sounds are ___
audible
breath sounds over the trachea and mainstream bronchi are __ and __ than over
the other lung fields because these airways have larger diameters and thus more
airflow than smaller airways
louder and harsher
gas exchange occurs in
the alveoli of the lungs
when fluid fills the alveoli __ __ may be audible on auscultation
fine crackles
excessive fluid in the alveoli interfere with
gas exchange, resulting in decreased or absent breath sounds in that portion of the lung
the upper respiratory tract is responsible for
moisturizing inhaled air and filtering noxious particles
respiration
is primarily an automatic process initiated by the respiratory center of the brainstem
(pons and medulla) based on cellular demands
the main trigger for breathing is
increased level of carbon dioxide in the blood
,when breathing is trigger
the diaphragm contacts and flattens pulling the lungs down. the thorax and lungs
elongate increasing the vertical diameter
with aging respiratory strength __
declines
with aging respiratory strength declines lungs lose __, flexibility __ in the
cartilage of the ribs, and bone density ___.
elasticity, decreases, decreases
if a patient has acute shortness of breath, immediately assess airway respiratory
and pulse rates, BP, and oxygen saturation. Auscultate the lungs to identify?
abnormalities such as diminished or absent breath sounds or evidence of fluid in the
lungs
-administer oxygen or a bronchodilating inhaler as ordered. if the patient is in bed
elevate the head of the bed to reduce the effect of gravity on the effort of breathing
orthopnea
difficulty breathing when lying flat often sleep on two or more pillows or even in recliners
paroxysmal nocturnal dyspnea (PND)
patients who awaken at night with sudden shortness of breath. the cause is fluid
overload resulting from the elevation of the legs, which shifts the fluid present there to
the bodies core
wheezing
associated with asthma, CHF, and bronchitis
-it occurs in response to narrowed bronchioles
-wheezing with asthma is worse in response to offending allergies, at night, and in the
early morning
patients in respiratory distress or with COPD often assume a __ position, leaning
forward on a stationary object such as table or with their elbows on their knees.
this position increases the size of the thoracic cavity, facilitating airflow.
tripod
hypoxemia
a low level of oxygen in the blood
bradypnea
is less than 10 breaths/min
tachypnea
is breathing greater than 24 breaths/min
pallor or cyanosis of the nail beds indicate __
hypoxia
crackles
are discontinuous sounds that are caused by fluid in the airways or alveoli or that result
from the opening of collapsed airways and alveoli while they reinflate during deep
breathing. they sound like hairs rubbing together near the ear or velcro opening and are
most often heard on inspiration although they can occasionally be heard during
expiration
__ are continous, high-pitched, musical sounds caused by air squeezing through
narrowed airways, as occurs in asthma.
wheezing
, rhonchi
continous, low-pitched, snoring sounds resulting from secretions moving around in
airways. may be clear with coughing and are heard most commonly in patients with
chronic bronchitis
Bronchophony
the word 99 is clear and louder over denser areas. it sounds as if the patient is speaking
directly into the stethoscope this is documented as positive bronchophony
egophony
the "EEE" sounds like a loud "AAA"
bronchial breath sounds
loud and high pitch
coarse and tubular
inspiration less than expiration
usually in larynx and trachea
bronchovesicular breath sounds
intermediate and intermediate in intensity and pitch
intermediated quality
inspiration equal to expiration
usually anteriorly between 1st and 2nd ICS; between scapula
vesicular breath sounds
soft and low intensity and pitch
whispering undertones
inspiration greater than expiration
usually over most of the lung fields
common respiratory symptoms include
chest pain
dyspnea
orthopnea
paroxysmal nocturnal dyspnea
cough
sputum
audible wheezing
change in functional ability
abnormal breathing patterns include
tachypnea
hyperventilation
bradypnea
hypoventilation
cheyne-strokes respiration
biot breathing
axonal breathing
apnea
adventitious lung sounds include
crackles, wheezes, rhonchi, pleural friction rub, and stridor
structurally the respiratory system is divided into upper and lower portions the
upper portion
