- Alveoli
-
site of gas exchange
Problem with gas exchange- fluid or edema -
Medulla oblongata and pons(brain stem)
&
Chemoreceptors -
Controls rate and depth of
respirations
responds to changes in the concentration of O2, CO2, and hydrogen ions in arterial blood
breathe- get rid of co2
Head injuries= no breathing - Phrenic Nerves
-
Diaphragm extremly important
Obese- when laying flat or sitting upright ability to breathe decreases (elevate HOB)
Paralized phrenic nerves-(paralized diaphragm)
diaphragm won't lower therefore ventalator (Iron lung-past HX) - Ineffectine breathing problem
- upper respiratory
- ineffective gas exchange
- Lower respiratory
- COPD
-
Chronic Obstructive Pulmonary Disease
2nd stimulus - low O2
Long term respiratory disease
HX of smoking - Pneumothorax
-
Abnormal opening in pleura space
space becomes more +
space fills with air
suck out air and insert chest tube - Normal respirations
-
O2 concentration in lungs
Hemoglobin 12-14gm
transfer of O2 to blood
transportation of O2 to tissues
Cells use O2 - Abdominal breathing (belly breathing)
-
move diaphragm
Lungs fixed - barrel shaped chest - Apnea
-
period of of no respirations
Normal periods of apnea
More than 10-12 seconds - increased CO2 - Acidic- may need ventalator
