121

Medulla Oblongata and Pons

automatic control of R

122

Cerebral Cortex

Voluntary or conscious control of R, singing, swimming

123

Chemoreceptors

increase in carbon dioxide increase R, co2 blown off

124

Aorta and Carotid arteries

decrease o2 increases R, increase o2, emergency ventilation, fight or flight response

125

Stress

flight or fight mechanism

126

Environment

Altitude, occupational hazards

127

Lifestyle

exercise, smoking

128

Health Status/Disease

lungs, nervous system, cardiovascular

129

Age

infants, children, elders

130

Factors that affect R function

stress, environment, lifestyle, diet, health status/disease, medications, age

131

Factors affecting gas transport

effective cardiac pump, adequate peripheral blood vessels for diffusion, adequate amount of plasma intravascular, normal RBCs

132

Infants R

30-60

133

Child >1 year R

25

134

Infant risk

maturing R center increases risk for R illness

135

Elder Risk

decrease lung elasticity, decrease in ability to pump and transport gases, exposure to environmental hazards through life time, decrease immune response = risk for respiratory illness

136

Information collected during nursing history when assessing oxygenation

restlessness, confusion, abnormal breathing patterns, cough, sputum, chest pain, fatigue, weakness, lightheadedness, med history respiratory, neurological, cardiovascular, environment, lifestyle, medications, diet

137

Function of Iron

Formation of Hgb - transports oxygen

138

Sources of Iron

organ meats, oats, prune juice

139

Absorption of Iron

Vitamin C increases absorption, calcium decreases absorption

140

Populations at risk for iron def

less than 18 months, pregnancy, lactation, menstruation, vegetarians, low socioeconomic groups

141

Oxygen Sat normal

95-100%

142

Areas to assess for cyanosis

nail beds, circumoral skin (around mouth), sublingual mucous membranes (under tongue), conjunctiva (eyes), earlobes, buccal mucosa (cheeks), lips, palms of hands, soles of feet

143

RBC Venous blood sample

trasport mechanism for oxygen

144

RBC normal value

3.5-5.0 million

145

Hemoglobin

binging site for oxygen inside the RBC, dependent on adequate iron intake

146

Normal Hgb

12-18g/100mL

147

Hematocrit

indicates adequate percentage of RBCs and fluid

148

Normal Hct

35-50%

149

Normal Chest

symmetrical from side to side, prominent clavicle, flat sternum, anterior/posterior diameter 1/3 to 1/2 the transverse diameter

150

Hypoxia

insufficient oxygen to body cells
