Gas Exchange/Chest Tubes/Drains/Trachs Flashcards
Pulmonary disease is classified by
alteration in the lung or heart
Understanding the pathophysiology of common ____________ problems can greatly affect the outcome of each individuals during gas exchange.
respiratory
Lungs characteristics
large surface area constantly exposed to the external environment
Lung disease is greatly influenced by what a pt is exposed to
environmental, occupation, personal, social habits
S/S of pulmonary alterations
cough
dyspnea
chest pain
abnormal sputum
hemoptysis
altered breathing patterns
cyanosis
fever
Dyspnea is described as
with s/s
subjective sensation of uncomfortable breathing
the feeling of being unable to get enough air described as air hunger, sob, labored breathing- causes disturbance of gas exchange, increase work of breathing, dz that damages lung tissue, pulmonary congestion r/t heart dz
s/s of dyspnea nostril flaring accessory muscles use, retraction more common in children
Hemoptysis
coughing up blood or bloody secretions from lungs
Cyanosis
bluish discoloration of skin and mucous membranes
Cough
protective reflex cleanse the lower airways by an explosive expiration
Chest pain can be described as
sharp or stabbing when breathing could be pleural
What is a symptom of severe or later sign of hypoxia
cyanosis
Orthopnea
dyspnea when lying down often sleeps propped up
Hypoventilation
inadequate alveolar ventilation r/t metabolic demands
Hypercapnia
retaining CO2
Hyperventilation
alveolar ventilation exceeding metabolic demands
Hypocapnia
a state of reduced carbon dioxide in the blood
Hypercapnia
breathing may be the normal cause- decreased drive to breathe – drug, CNS ( brain spine) obstruction, increased work of breathing
Clubbing
bulbous enlargement of the end of a finger or toe
What sign is related to chronic hypoxemia?
clubbing
Hypoxemia
abnormally low concentration of oxygen in the blood
Hypoxia
deficiency in the amount of oxygen reaching the tissues
Aspiration
passage of fluid or solid particles into the lung
Atelectasis
collapse of alveoli
Hypoxia dx
ABGs
Pulmonary function
Hgb and Hct
Clinical S/S
Hx
Pulse Ox below 90%
Hypoxia Complications
cellular death in target tissue with body-wide effects
- heart and brain are most affected
Hypoxia Risk factors
Chronic or acute hypoxia
inflammation problems
immobility in elderly
Nursing Interventions for Hypoxia
maintain fluids, suction, TCDB
Position in semi to high fowlers
O2, expectorants, ambulation
Tracheostomy is a medical procedure that is permeant or temporary?
Both
