Respiratory Flashcards
what’s too little O2 cause
cellular hypoxia and anaerobic metabolism
what does retained CO2 cause
respiratory acidosis
Ventilation vs. Respiration
ventilation is mechanical and involves the movement of air respiration is physiologic and involves the exchange of gases in the alveoli
hypoxia vs. hypoxemia
hypoxia is tissues
hypoxemia is blood
what’s apart of the upper airway
nasal passages, sinuses, pharynx, larynx, upper trachea
goblet cells produce and secrete mucus to trap particles
cilia move mucus/trapped particles up and out of the airway
what’s apart of the lower airway
lower trachea, bronchi, bronchioles, alveoli
sterile environment, smooth muscles for constricting
what’s the pleura cavity
normally a thin space between outside wall of the kung and inside of chest wall, there’s slight sub-atmosphtic pressure that maintain lung expansion
what’s empyema
collection of purulent fluid in this space
what are some pulmonary changes in the elderly
chest wall stiffening, cartilage calcification, decrease recoil and compliance, fewer functions alveoli, decrease rest muscle strength, thicker mucous, slower response to hypoxemia and hypercapnia
what’s OSA
obstructive sleep apnea, intermittent absence of airflow through mouth/nose during sleep
causes of OSA
muscle tone, patency of airway, obesity, age, large neck circumference, smoking
effects of OSA
lead to chronic health problems, HTN, dysrhythmias, HF
Influenza (transmission, what it can turn into)
upper resp infection that can progress to pneumonia, transmitted via droplets, true influenza has rapid onset and severe symptoms
what’s pneumonia (causes, who do we worry about, clinical manifestations)
multiple causes (bacteria, viruses, fungi, chemical, aspiration that lead to inflammation and impaired gas exchange in lungs)
worry about old and young, immunocompromised, chronic illness
clinical manifestations (cough, fever, chills, dyspnea, tachypnea, crackles, pleuritic CP)
pneumonia vaccine who is it for
anyone 65 or older, long term health problem or immunosuppression, smokers or have asthma, live in nursing homes for long-term care facility
