What are upper airway breathing noises?
crowing
gurgling
snoring
stridor
What is crowing?
a sound like a crow cawing that occurs when the muscles around the larynx spasm and narrow the opening into the trachea. Air rushing through the restricted passage causes the sound.
what is gurgling?
sound like gargling, usually indicates the presence of blood, vomitus, secretions, or other liquid in the airway. Immediately suction the substance from the airway.
What is snoring?
occurs when the upper airway is partially obstructed by the tongue or by relaxed tissues in the pharynx
What is stridor?
harsh, high-pitched sound heard during inspiration. It is characteristic of a significant upper airway obstruction from swelling in the larynx. Stridor may also be heard if a mechanical obstruction by food or other objects is present.
What is a COPD
Chronic obstructive pulmonary disease
causes an obstruction of airflow through the respiratory tract, leading to a reduction in gas exchange
examples: emphysema and chronic bronchitis
What is Emphysema?
a 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
What are key points of Emphysema?
more common in men than in women and the primary causation factor is cigarette smoking
lung tissue loses its elasticity, the alveoli become distended with trapped air, and the walls of the alveoli are destroyed.
pt retains more co2
Exhaling becomes an active rather than a passive process, requiring muscular contraction, and the patient uses most of his energy to breathe.
What are the emphysema s/s?
-Pursed-lip breathing dead give away that they are having -trouble emptying air out of their lungs
-Extreme difficulty of breathing on minimal exertion
-Pink complexion (These patients are often called “pink puffers.”)
-Tachypnea (breathing rate usually greater than 20 per minute at rest)
-Tachycardia
-Diaphoresis
-Tripod position
-May be on home oxygen to treat episodic cases of asthma.
What is chronic bronchitis?
DEFINED AS Productive cough for two of more months for two or years in a row.
What are the key points of chronic bronchitis?
the alveoli remain unaffected by the disease, but inflamed and swollen bronchioles and thick mucus restrict airflow to the alveoli so that they do not expand fully, causing respiratory distress and possible hypoxia.
Recurrent infections leave scar tissue that further narrows the airway.
A major problem with chronic bronchitis is the swelling and thickening of the lining of the lower airways and an increase in mucus production.
The airways become very narrow, causing a high resistance to air movement and chronic difficulty in breathing.
what are the s/s of chronic bronchitis?
Chronic cyanotic complexion (They are often called “blue bloaters”.)
Difficulty in breathing, but less prominent than with emphysema
Vigorous productive chronic cough with sputum
Coarse rhonchi usually heard upon auscultation of the lungs
Wheezes and possibly crackles at the bases of the lungs
Respiratory infections that lead to more acute episodes
What is 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. This leads to poor gas exchange and eventual hypoxia.
What is pulmonary edema?
the presence of fluid in the space between the alveoli and the capillaries that surround them, interfering with gas exchange.
most significant problem associated with pulmonary edema is hypoxia
often associated with left side heart failure
What is a pulmonary embolism?
a 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 may also be caused by an air bubble, a fat particle, a foreign body, or amniotic fluid.
what is a thrombosis?
it is a clot
What are key points of risk factor for pulmonary embolism?
Patients at risk for suffering a pulmonary embolism are those who experience long periods of immobility, with heart disease, recent surgery, long-bone fractures, venous pooling associated with pregnancy, cancer, deep vein thrombosis (development of clots in the veins, most commonly in the legs); those taking estrogen therapy; and those who smoke.
What is cardiogenic pulmonary edema?
typically related to an inadequate pumping function of the heart that drastically increases the pressure in the pulmonary capillaries. This forces fluid to leak into the space
what is noncardiogenic pulmonary edema?
known as acute respiratory distress syndrome (ARDS), results from destruction of the capillary bed that allows fluid to leak out. Common causes of noncardiogenic pulmonary edema are severe pneumonia, aspiration of vomit, submersion, narcotic overdose, inhalation of smoke or other toxic gases, ascent to a high altitude, and trauma.
What are the s/s of pulmonary embolism?
Unexplained dyspnea
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
What are the s/s of pulmonary edema?
Dyspnea, especially on exertion
Difficulty in breathing when lying flat
Pink and/or frothy sputum (cardiogenic cause only)
Tachycardia
Anxiety, apprehension, combativeness, and confusion
Tripod position with legs dangling
Fatigue
Crackles and possibly wheezing on auscultation
Cyanosis or dusky-color skin
Pale, moist skin
Distended neck veins (cardiogenic cause only)
Swollen lower extremities (cardiogenic cause only)
Cough
Fever
Symptoms of cardiac compromise (cardiogenic cause only)
What is spontaneous pneumothorax?
portion of the visceral pleura ruptures without any trauma having been applied to the chest. This allows air to enter the pleural cavity, disrupting its normally negative pressure and causing the lung to collapse.
What are the two types of spontaneous pneumothorax?
primary and secondary
What is primary spontaneous pneumothorax?
patients who have no underlying lung disease. Primary spontaneous pneumothorax occurs in patients in their teenage years to early 20s who are tall and thin.
