Chapter 16 Flashcards
(48 cards)
wheezing
high-pitched, musical, whistling sound that is best heard initially on exhalation but can also be heard during inhalation in more severe cases. It is an indication of swelling and constriction of the inner lining of the lower airways, primarily the bronchioles
Rhonchi
also be referred to as coarse crackles, are snoring or rattling noises heard on auscultation. They indicate obstruction of the larger conducting airways of the respiratory tract by thick secretions of mucus. Rhonchi are often heard in chronic bronchitis, emphysema, aspiration, and pneumonia.
crackles/rales
bubbly or crackling sounds heard during inhalation. These sounds are associated with fluid that has surrounded or filled the alveoli or small bronchioles.
can indicate pulmonary edema or pneumonia
hypoxemia
decreased oxygen in bloodstream
hypercarba
increased co2 in bloodstream
common s/s of respiratory distress
-Subjective complaint of shortness of breath
-Restlessness and anxiety
-Tachycardia (early finding)
-bradycardia (later finding)
-Tachypnea
-Pale, cool, clammy skin (early finding)
-cyanosis (later finding)
-Abnormal respiratory pattern
-Wheezing, rhonchi, or crackles
-Difficulty or inability to speak
-Muscle retractions
-Altered mental status
-Abdominal breathing
-Excessive coughing
-Tripod position
-Pulse oximeter reading < 94
breathing disturbance 3 categories
Respiratory distress
Respiratory failure
Respiratory arrest
respiratory distress
has a normal minute ventilation from compensation in the tidal volume (breathing deeper) and/or the respiratory rate (breathing faster). Because the tidal volume and respiratory rate are still adequate, the patient is compensating
respiratory failure
when the tidal volume or respiratory rate is inadequate and no longer can provide an adequate oxygenation of the cells. If the tidal volume decreases or the respiratory rate increases or decreases significantly, you must provide immediate positive pressure ventilation and oxygenation with a bag-valve-mask device or other ventilation device
respiratory arrest
complete cessation of breathing effort or the patient experiences agonal breathing
diseases that cause respiratory problems
Obstructive pulmonary diseases
-Emphysema
-Chronic bronchitis
-Asthma
Pneumonia
Pulmonary embolism
Pulmonary edema
Spontaneous pneumothorax
Hyperventilation syndrome
Epiglottitis
Pertussis
Cystic fibrosis
Poisonous exposures
Viral respiratory infections
emphysema
permanent disease process distal to the terminal bronchioles that is characterized by the destruction of the alveolar walls and the distention of the alveolar sacs and a gradual destruction of the pulmonary capillary beds with a severe reduction in the alveolar/capillary area in which gas exchange can occur.
more common in men
emphysema s/s
Anxious, alert, and oriented
Dyspneic
Uses accessory muscles
Thin, barrel-chest appearance
Coughing, but with little sputum
pink puffer
Prolonged exhalation
Diminished breath sounds
Wheezing and rhonchi on auscultation
Pursed-lip breathing (physiologic PEEP)
Extreme difficulty of breathing on minimal exertion
Tachypnea—breathing rate usually greater than 20 per minute at rest
Tachycardia
Diaphoresis (sweating; moist skin)
Tripod position
May be on home oxygen
chronic bronchitis
characterized by a productive cough that persists for at least three consecutive months a year for at least two consecutive years.
involves inflammation, swelling, and thickening of the lining of the bronchi and bronchioles and excessive mucus production
chronic bronchitis s/s
Cough (hallmark sign) is prominent; vigorous coughing produces sputum
blue bloater
Minimal difficulty in breathing and anxiety, unless in respiratory failure
Scattered rales (crackles) and coarse rhonchi
Wheezes and, possibly, crackles at the bases of the lungs
Asterixis (flapping of the extended wrists) may be seen in respiratory failure
asthma
increased sensitivity of the airways to irritants and allergens, causing bronchospasm, which is a diffuse, reversible narrowing of the bronchi and bronchioles, as well as inflammation to the lining of the lower airways.
extrinsic asthma
results from a reaction to dust, pollen, smoke, or other irritants in the air
intrinsic asthma
usually results from infection, emotional stress, or strenuous exercise.
asthma s/s
dyspnea
coughing
wheezing
tachypnea
tachycardia
use of accessory muscles
diaphoresis
anxiety
chest tightness
difficulty sleeping
pulsus paradoxus
critically ill asthma s/s
upright position
tachypnea
tachycardia
pulsus paradoxia
pale cool diupheretic skin
single word speech
accessory muscle use
wheezing
decreasing conciousness
extreme fatigue
spo2 < 90 w/o2
pneumonia
acute infectious disease caused by bacterium or a virus that affects the lower respiratory tract and causes lung inflammation and fluid- or pus-filled alveoli
pneumonia s/s
decreased appetite
fever
cough
dyspnea or tachypnea
tachycardia
sharp localized chest pain worse with deep breath/cough
shallow respirations
self splinting thorax
Crackles, localized wheezing, and rhonchi
Altered mental status, especially in the elderly
Diaphoresis
Cyanosis
pulmonary embolism
sudden blockage of blood flow through a pulmonary artery or one of its branches. The embolism is usually caused by a blood clot, but it can also be caused by an air bubble, a fat particle, a foreign body, or amniotic fluid
pulmonary embolism s/s
Sudden onset of unexplained dyspnea
Signs of difficulty in breathing or respiratory distress; rapid breathing
Sudden onset of sharp, stabbing chest pain predominantly during inhalation
Cough (might cough up blood)
Tachypnea
Tachycardia
Syncope (fainting)
Cool, moist skin
Restlessness, anxiety, or sense of doom
Decrease in blood pressure or hypotension (late sign)
Cyanosis (might be severe) (late sign)
Distended neck veins (late sign)
Crackles
Fever
signs of complete circulatory collapse
