Gas Exchange Flashcards
what is gas exchange
the process by which o2 is transported to cells and co2 is transported from cells
what is ischemia
inadequate blood supply to part of body
not perfusing
no 02 exchange
what is hypoxia
inadequate o2 supply in body tissues or cells
what is anoxia
absence of o2
what is diffusion
moving from an area of high concentration to low concetration
what is hypoxemia
lack of o2 blood-arterial
which side of the heart recieves 02 blood from lungd
left side
what is ventilation
flow of air into and out of alveoli
what is transport
02 transported by RBCs
what is perfusion
flow of blood to alveoli capillaries
why does impairment of gas exchnage occur
ineffective ventilation
reduced capacity for gas transportation
inadequate perfusion
what is asthma
inflammation and airway tissue sensitivity
what lab assessments are done for asthma
ABGs
cbcs
sputum
biopsy
what is a control therapy drug used daily for asthma
theophylline
what is a reliever drug that is used to stop an asthma attack
albuterol
what is an example of an anti-inflammatory agent inhaler
QVAR
what can happen if there is impaired gas exchange
cell death
what is the greatest risk factor of COPD
cigarette smoking
what are some complications of COPD
hypoxemia
acidosis
respiratory infection
cardiac failure
dysrhythmias
respiratory failure
what is clinical management and primary prevention for COPD
infection control (AVOID SERIOUS RESPIRATORY INFECTIONS)
smoking cessation
immunizations
preventing postop complications (pneumonia)
what are some cues for COPD
decreased gas exchange
wt loss
anxiety
decreased endurance
potential for pneumonia
what are 2 positions good for COPD patients
upright or tripod
what does chest physiotherapy do
physically break up mucus
