Terms to Know
process of moving gases into and out of lungs
ventilation
Infants and Toddlers
What are 2 assessment findings to note when assessing a patient for adequate oxygenation?
Perfusion
To see if there is inadequate central perfusion what could be noted
Tachycardia
Orthostatic hypotension
Murmur
Shortness of breath
Abnormal heart rhythm
Diaphoresis
Anxiety
ability of the cardiovascular system to pump oxygenated blood to the tissue and return deoxygenated blood to the lungs
perfusion
School Age/Adolescents
Name 3 types of testing that can be conducted in order to observe or diagnose problems with oxygenation?
a localized area of ischemia necrosis produced by occlusion of an arterial supply or the venous drainage
infarction
Nurse would note these signs if their was inadequate perfusion to lower extremities
Less hair, pale
Cool to touch
Diminished/absent pulses
process of exchange of respiratory gases in the alveoli of the lungs to the capillaries of the body tissues
diffusion
Young-Middle age Adults
What are some ways to prevent problems with oxygenation?
Infection control
Smoking cessation
Immunizations
Post op complications
the absence of oxygen supply to an organ or tissue
anoxia
Signs present due to inadequate perfusion in the kidneys
Poor urine production
Edema
Increased blood pressure
Slow capillary refill
an insufficient supply of blood to an organ, usually due to a blocked artery
ischemia
Older Adults
What are some interventions the nurse can implicate when problems with oxygenation occur?
generated by cardiac output, moving blood into the heart through the peripheral system
central perfusion
Signs present due to inadequate perfusion to brain
One sided weakness
Difficulty speaking
Carotid artery occlusion
an inadequate amount of oxygen traveling in the blood
hypoxemia
Lifestyle Risk Factors
What is the disease process discussed with oxygenation?
Pneumonia
volume of blood that flows through the target tissues
tissue perfusion
Who is at greatest risk for poor perfusion?
Middle aged adults, esp. males and African Americans, Infants with congenital heart defects, older adults due to anatomic changes (fibrosis, sclerosis, atherosclerosis)
