what is oxygenation - ANSWER process of delivering oxygen to the blood.
- needed to sustain life
- occurs by mechanisms of ventilation, perfusion, and transport of resp. gas
how do we normally oxygenate our body - ANSWER cardiac and respiratory system
work together to ventilate and perfuse
Factors affecting oxygenation - ANSWER physiological:
- decreased O2 carrying capacity
- decreased inspired [O2]
- hypovolemia
- increased metabolic rate
conditions affecting chest wall:
- pregnancy
- obesity
- musculokeletal abnormalities
- trauma
- neuromuscular diseases
- CNS alterations
- chronic diseases
, define hyperventilation - ANSWER Ventilation that exceeds needs of the body, lowering
blood CO2 levels.
- breathing too fast
define hypoventilation - ANSWER inadequate ventilation needed to meet body's O2
demand/eliminate CO2
- breathing too slowly
define hypoxia - ANSWER inadequate tissue oxygenation at the cellular level
define cyanosis - ANSWER a bluish discoloration of the ski or mucous membranes
resulting from poor circulation or inadequate oxygenation of the blood.
nursing management of pts when impaired oxygenation - ANSWER - promotion of lung
expansion
- management of dsypnea
- maintenance of airway
define dyspnea - ANSWER shortness of breath (SOB)
what is postural drainage - ANSWER - positioning techniques that move lung
secretions into the trachea
what is the postural drainage position for right lower lobe, posterior - ANSWER Prone
in Trendelenburg's position with abdomen and thorax elevated
T or F: suctioning techniques may be used if a pt is unable to clear secretions with
coughing - ANSWER TRUE
