Respiratory Disorders Flashcards
tachypnea
rapid, superficial breathing
hyperventilation
rapid, deep breathing
bradypnea
slow, deep breathing
hypoventilation
slow, shallow breathing
apnea
cessation of breathing
hyperpnea
increased depth of respiration with a normal to increased rate; regular rhythm
Cheyne-Stokes respiration
periodic breathing associated with periods of apnea, alternating regularly with a series of respiratory cycles that gradually increases, then decreases in rate and depth
ataxic breathing
periods of apnea alternating irregularly with a series of shallow breaths of equal depth
Kussmaul’s respiration
deep, regular sighing respirations with an increase in respiratory rate; a form of pursed-lip breathing
apneusis
long, gasping inspiratory phase followed by a short, inadequate expiratory phase
obstructed breathing
long, ineffective expiratory phase with shallow, increased respirations
thoracentesis
removal of excess fluid from pleural cavity, prevent atelectasis
tracheotomy
incision into the trachea below the larynx to permit air intake
extrinsic asthma
acute asthmatic episodes are triggered by type I hypersensitivity reactions; sensitized IgE trigger histamine release
intrinsic asthma
asthma attacks are initiated by hyper-responsive tissue in airway
early phase manifestations of asthma
tight feeling in chest, expiratory wheezing, dyspnea and tachypnea, pain when breathing, non-productive cough
manifestations of severe asthma attacks
expiratory and inspiratory wheezing, worsening dyspnea, use of accessory muscles and retractions, thick/sticky mucous, tachycardia, hypoxia
asthma
- intermittent or persistent airway obstruction
- obstruction due to inflammation, bronchoconstriction/bronchospasms, engorged blood vessels, excess mucous production
status asthmaticus
severe, persistent asthma attacks; a medical emergency
status asthmaticus manifestations
- no response to usual therapy, worsening respiratory status
- pulsus paradoxus
pulsus paradoxus
pulse differs on inspiration and expiration; speeds up during inspiration, slows down during expiration
FEV1 in asthmatic patients
less than 80% of normal FEV1 indicates oncoming asthma attack
asthma ABGs
hypoxemia, hypercapnia, acidosis
emphysema
abnormal irreversible enlargement of the gas-exchange airways accompanied by destruction of alveolar walls
emphysema causes
- smoking
- genetic deficiency in alpha-1 antitrypsin
FEV1 in emphysema patients
less than 30% of normal
emphysema ABGs
hypercapnia
hypoxemia in advanced stages
chronic bronchitis
airway obstruction of major and small airways due to inflammation of mucosa and thickening of bronchiole walls
clinical diagnosis for chronic bronchitis
inflammation, obstruction, repeated infection, chronic coughing for 3 months or longer, two times in 2 years
