What is the Respiratory System Responsible Exchange of gases in
the body for?
Intake of O2 and release of
CO2 Maintain acid-base
balance Maintains body
fluids
Assists with speech
Respiratory cycle (AKA) Breathing
or
Respiration
,3 sections of the thorax Mediastinum
-Heart
-Trachea
-Esophagus
-Major blood vessels
Right Pleural
Cavity Left Pleural
Cavity
Upper respiratory tract Nose
Mouth
Sinuses
Pharynx
Larynx
Trachea
Lower respiratory tract Distal trachea
Bronchi
Lungs
Right=3 lobes
Left=2
lobes
Plural membrane
Mediastinum
Eupnea Regular, even rhythmic breathing
Dyspnea Change in this pattern producing
-SOB or difficulty breathing
, Respiratory Landmarks (Bony Landmark) Clavicles
Sternum-1st
Ribs
1-7=True
8-10=False
11-12=Floating ribs
Vertebral Column
Angle of Louis
Apex of the Lungs Slightly superior to the inner 1/3rd of the clavicle
Base of the lungs Base is at the level of the diaphragm
Pleural fluid keeps the lungs lubricated to avoid friction and to allow
the lungs to glide during inspiration & expiration
Normal Respiration 12-20 per min w/ adults
40-80 per min w/ newborn
35 per min by 5 y/o
Special considerations (Pediatric) Infants & Children
Change from intrauterine to extra uterine breathing
Use abdominal muscles for breathing during infancy and
early childhood
-more prone to respiratory failure
Special considerations (Pregnant) +2 per minute (14-22 bpm)
-needs 20% more oxygen than normal
Muscles and cartilage of ribs relax
Inspiratory capacity increases
Mild respiratory alkalosis
