🗑

🗑
|
||||

cricoid cartilage | below thyroid cartilage, attached to 1st ring of tracheal cartilage, only complete ring with posterior bulky part, narrowest part in children
🗑
|
||||
sellick maneuver | putting pressure on cricoid cartilage to occlude esophagus & prevent regurgitation
🗑
|
||||
arytenoid cartilages | 2 pyramid shaped, attached to vocal folds & pharyngeal wall, open & close vocal cords, landmark for ET tube
🗑
|
||||
glottis | slitlike opening between vocal cords leading into trachea, in adult narrowest part
🗑
|
||||
vagus nerve | richly lines larynx, stimulation of pharyngeal & laryngeal mucous membranes can cause bradycardia, hypotension & decreased respiratory rate, sends signals to medullla oblongata & pons in brain to control breathing
🗑
|
||||
serous membrane/pleura | 2 layer epithelial membrane that lines body cavities & covers surfaces of organs, form sac & includes 2 layers
🗑
|
||||
apex | top of lungs
🗑
|
||||
hilum | slits in ea lung where bronchi, pulmonary blood vessels & nerves are firmly anchored in meshwork of dense connective tissue in2 lung, form "root of the lung", only spot where lungs are anchored
🗑
|
||||
visceral pleura | membrane closely covering the lungs
🗑
|
||||
parietal pleura | lines inner surface of chest wall, diaphragm & mediastinum
🗑
|
||||
pleural space | seperates parietal & visceral pleura in lungs, contains just a few drops of pleural fluid to prevent friction as lung tissue expands & contracts
🗑
|
||||
external respiration | involves exchange of gases between circulating blood & air & is carried on by expansion & contraction of lungs
🗑
|
||||
internal respiration | involves exchange of dissolved gases between circulating blood & interstitial fluids in peripheral tissues
🗑
|
||||
cellular respiration | use of O2 by cells in the process of metabolism
🗑
|
||||
diaphragm | largest, wide muscule separating thoracic/chest cavity from abdominal cavity, slants upward anteriorly & dome shaped when relaxed, contracts downward
🗑
|
||||
ventilation | process of moving air in & out of lungs, includes inspiration & expiration
🗑
|
||||
process of breathing | initiated by respiratory center in medulla oblongata & pons in brain, respond to increased levels of CO2 in blood
🗑
|
||||
minute volume | volume of air exchanged in 1 min, about 6000mL - 16,000mL average, necessary to remove CO2 & bring in sufficient supplies of O2
🗑
|
||||
tidal volume | air inhaled & exhaled in single respiration, 500mL - 800mL, 12-20x per min
🗑
|
||||
dead air space | air remaining in trachea & bronchi unavailabe for gas exchange, about 150 mL
🗑
|
||||
physiological dead space | development of additional dead space from diseases such as COPD or atelectasis
🗑
|
||||
total lung capacity | about 6L in average adult male,
🗑
|
||||
PO2 or PCO2 | abbreviation for partial pressure of O2 or carbon dioxide
🗑
|
||||
medulla oblongata & pons | in brainstem, control rate & depth of breathing, connected to respiratory muscles by vagus nerve, pons 2ndary control center if medulla fails, also controls expiration
🗑
|
||||
hypoxia | increased respirations, insufficient oxygenation of the cells
🗑
|
||||
hiccup | sudden inspiration caused by spasmodic contraction of the diaphragm & intermittent spastic closure of glottis
🗑
|
||||
sighing | incoluntary slow deep breath followed by prolonged expiration, hyperinflates the lungs & opens atelectatic alveoli, normally about once per min
🗑
|
||||
cheyne-stokes breathing | regular pattern of gradually incerasing rate & tidal volume followed by gradual decrease & then short period of apnea, associated with brainstem insult
🗑
|
||||
kussmaul breathing | deep gasping respirations, common in diabetic coma
🗑
|
||||
biot's respirations | group of quick, shallow inspirations followed by regular or irregular periods of apnea, seen with increased intracranial pressure
🗑
|
||||
central neurogenic hyperventilation | pattern of deep rapid respirations similar to kussmaul breathing, also indicative of increased intracranial pressure
🗑
|
||||
agonal breathing | pattern of slow shallow irregular respirations, results from brain anoxia
🗑
|
||||
pulsus paradoxus | systolic B/P decreases more than 10mmHg during inspiration, seen in COPD, severe asthma, cardiac tamponade, pericardial effusion, CHF, AMI & tension pneumothorax
🗑

🗑
|
||||

🗑
|
||||
respirations | exchange of gases between the body cells & the atmosphere

🗑
|
||||
aphonia | cannot speak
🗑
|
||||
atelectasis | dead space, collapse of alveoli
🗑
|
||||
dyspnea | shortness of breath or difficulty breathing
🗑
