Respiratory System Anatomy and Physiol...
Air must move more quickly in the infant's narrowed airway to get the needed amount of air into the
lungs.
The friction of the quickly moving air against the side of the airway increases airway resistance.
,The infant must use more effort to breathe and must breathe faster to get adequate oxygen.
Position of trachea
In children, the trachea is shorter and the angle of the right bronchus at bifurcation is more acute than
in the adult. - more of a sharp angle = hard to intubate
When you are resuscitating or suctioning, you must allow for these differences.
Respiratory System Anatomy and Physiology: Pediatric vs. Adult
Lower airway differences -Correct Answers: Growth of alveoli
Diaphragm use for respirations
Use of accessory muscles
Higher metabolic rate requires more oxygen
Alveoli's begin to develop at 36 weeks gestation and continue to develop for first 5-8 years of life,
followed by further development in size and complexity
Under the age of 6 years, the diaphragm is the major muscle of breathing because intercostal muscles
are immature
Signs of Respiratory Distress in Children -Correct Answers: Wheezing
Continuous low pitched, rattling lung sounds that often resemble snoring. - like rubbing hair b/w fingers
Crackles
abnormal crackling or rattling sound, also called crackles
Crackles (Rales) Crackles are the sounds you will hear in a lung field that has fluid in the small airways. As
stated before, crackles and rales are the samething, and this can often lead to confusion among health
care providers. Crackles come in two flavours: fine and coarse.
