helps prevent or treat hypoxia Oxygen therapy
hypoxemia a deficiency of arterial blood oxygen,
results in
hypoxia
___levels and acid base balance Hemoglobin
status directly affect oxygenation
because acidemia increases ability
of
____ to release oxygen to tissues
while
alkalemia decreases ability of
____ to
release oxygen to tissues
COPD Pt.s may have normal arterial oxygen levels
during day
but oxygen desaturation, a reduction in
arterial
oxygen level during sleep
, Signs and symptoms associated Apprehension. Anxiety. Increased pulse
with rate.
hypoxia Increased rate and depth of respiration.
Decreased
or adventitious lung sounds. Elevated
blood
pressure.Pulse ox less than 90%.
Dyspnea. Use of
accessory muscles, rib retractions. Cardiac
dysrhythmias. Pallor, cyanosis. Increased
fatigue.
Dizziness. Clubbing of nails.
occurs because uncontrolled Acute respiratory failure with COPD
administration of oxygen in this
condition may cause acute
hypoventilation and carbon dioxide
retention. Recommendation is to
limit
oxygen administration to minimum
need to raise arterial oxygen
saturation 88% to 92% and no
higher
In early stages of hypoxia, blood elevated, hypotension
pressure is____, if it remains
uncorrected ____develops.
Oxygen therapy can relieve pulmonary vasoconstriction, right sided
workload,
and decreases myocardial ischemia.
P.591 for different types of oxygen ...
