Components of Respiratory System
- Spinal Cord
- Pulmonary Circulation
Diaphram does what?
It is the major muscle of breathing that curves downward and connects to the sub xiphoid
What are Intercostal Muscles
They are the muscles between the ribs that control expanding/compressing of the ribcage
Ventilation is What + What
Inhalation and Exhalation
Respiratory Failure is
The point in breathing where the O2 intake is not enough to support life
Respiratory Arrest is?
When breathing stops completely
Inhalation takes about _____ the time of ventilation
Exhalation takes about ______ the time of ventilation
How does the diaphram move during inhalation
Outward and Downward
Intercostal Muscles move how during inhalation
Moves ribs outward and upward
During Exhalation the diaphram moves how?
It relaxes, Moves upward and decreases in size
During Exhalation the Intercostal muscles move how?
They relax and move inward and downward
Normal Respiration Rate of an Adult is?
12-20 Breaths per minute
Normal Respiration of a Child is?
15-30 Breaths per minute
Normal Respiration of an Infant is?
25-50 Breaths per minute
The first way to tell if you have adequate breathing is?
Look, Feel and Listen
Name some ways you can also tell if you have adequate respiration
- Equal Rise of Chest
- Present and Clear Breath Sounds
- Feel air moving in and out of nose/mouth
- Normal Skin color
- Normal Rate/Quality/Depth
What are some characteristics of Inadequate Breathing
- Uneven Chest Rise
- Abdominal Breathing
- Diminished Breath Sounds
- Abnormal Breath Sounds (Rales/Wheezing/Rhonchi/Stridor)
What are some signs of Inadequate Breathing?
- Rate is to fast or slow
- Shallow, Deep or Labored
- Cyanosis of Lips/Skin/Nail Beds
- Prolonged Inspirations/Exhalations
- Cannot speak in full sentences

- Providing Supplement O2
Causes of Airway Obstruction can be?
- Foreign Bodies
- Trauma to face and neck
- Allergic Reactions
Types of Artificial Airways
OPA and NPA
What does OPA stand for
What does NPA stand for?
Name Types of Oxygen Delivery Systems

What O2 % does Mouth to Mask Provide with O2 attached
How much O2 can a FROPVD deliver?
100% O2 up to 40 liters, relief valve that should open at 60cm water, and should only be used on children
What are the minimum requirements for a adequate suction device?
Should have an intake of 30 LPM at the end of the tube. Will happen if it can generate a vaccum of no less then 300mmhg when it is clamped
Name the parts of the suction system
Tubing, Suction tips, Suction Catheters, Collection Containers and a Container of Sterile water.
What is the maximum time you should suction for?
15 Seconds, then oxygenate.
If more suction is needed what should you do?
Ventilate 2 minutes then again suction
How should you suction?
Always on the way out
