🫁 ANATOMY
This cartilage forms the prominent "Adam's apple."
What is the thyroid cartilage?
A normal adult respiratory rate.
What is 12–20 breaths/minute?
The most common airway obstruction in an unconscious adult.
What is the tongue?
The physical act of moving air into and out of the lungs.
What is ventilation?
Normal end-tidal CO₂.
What is 35–45 mmHg?
This structure divides the trachea into the right and left mainstem bronchi.
What is the carina?
This respiratory pattern is commonly associated with metabolic acidosis.
What are Kussmaul respirations?
This maneuver should be used when spinal injury is NOT suspected.
What is the head tilt–chin lift?
The loading of oxygen onto hemoglobin.
What is oxygenation?
A patient has an ETCO₂ of 18 mmHg. Name two possible causes.
What is:
These tiny structures are the site of oxygen and carbon dioxide exchange.
What are the alveoli?
A patient has occasional gasping breaths after cardiac arrest.
What are agonal respirations?
This maneuver minimizes cervical spine movement.
What is the jaw-thrust maneuver?
The exchange of oxygen and carbon dioxide between the alveoli and pulmonary capillaries.
What is external respiration?
Ventilation continues but perfusion stops.
What is dead-space ventilation?
Place these airway structures in order from superior to inferior:
What is: Nasopharynx → Oropharynx → Larynx → Trachea?
Name FOUR findings indicating inadequate breathing.
What are:
If you hear this sound during assessment, suctioning should be performed immediately.
What is gurgling?
The exchange of oxygen and carbon dioxide between systemic capillaries and body cells.
What is internal respiration?
Perfusion continues but ventilation stops.
What is a shunt (V/Q mismatch)?
Name the SIX structures contained within the mediastinum.
What are:
Identify the respiratory pattern:
Breathing gradually becomes deeper and faster before slowing, followed by apnea.
What are Cheyne-Stokes respirations?
Place these interventions in the proper order:
What is:
Explain why oxygenation can occur without adequate tissue respiration.
What is ,oxygen may be present in the bloodstream but cannot be delivered to or utilized by tissues due to poor perfusion or cellular dysfunction.
You arrive to find a patient unconscious after falling from a roof.
Respirations are 8/min, shallow.
Snoring respirations are heard.
There is blood in the mouth.
What FOUR airway interventions should be performed first?
What is:
