|
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 |
