Oxygen Therapy
This device uses color-coded adapters to deliver exact oxygen levels.
Venturi mask (24–50%)
This tube has a cuff that seals the airway and keeps air from leaking out.
Endotracheal tube
The left ventricle pumps blood to this part of the body.
The whole body
Normal blood pH is between these two numbers
7.35–7.45
Keeps the lungs from collapsing after each breath.
PEEP
Gives a comfy flow of oxygen right into your nose.
Nasal cannula (24–44%)
What device helps you look down a patient’s throat during intubation?
Laryngoscope
The right ventricle pumps blood to this organ.
The lungs
Too much CO₂ makes your blood too ____.
Acidic
The amount of air the vent gives with each breath.
Tidal volume
This mask must run at least 5 L/min or you’ll trap CO₂!
Simple mask
The “mini vacuum” that clears out mucus.
Suction catheter
When oxygen levels drop, we call it ____.
Hypoxia
Too little CO₂ makes your blood too ____.
Basic / Alkaline
The vent alarm is going off for high pressure! What might that mean?
Secretions or kinked tubing
This high-tech nasal cannula delivers warm, moist O₂ up to 100%.
High-flow nasal cannula
Used to warm and moisten air in the vent circuit.
HME (Heat Moisture Exchanger)
Device that measures oxygen saturation (usually 95–100%).
Pulse oximeter
The kidneys control this chemical to help balance pH.
Bicarbonate (HCO₃⁻)
This mode gives set breaths even if the patient doesn’t try.
Control mode
Best for COPD patients who need precise oxygen levels.
Venturi mask
The first step when the airway is blocked.
Head-tilt, chin-lift
The sound of air moving through your lungs.
Breath sounds
A low PaO₂ means the patient has ____.
Low oxygen / hypoxemia
