Oxygen Therapy
This oxygen device delivers 1–6 L/min and provides approximately 24–44% FiO₂
This structure connects the larynx to the bronchi.
What is the trachea?
The normal adult respiratory rate range.
What is 12–20 breaths per minute?
This handheld device commonly delivers bronchodilators like albuterol.
What is a metered dose inhaler (MDI)?
This airway device prevents the tongue from obstructing the airway in unconscious patients.
What is an oropharyngeal airway (OPA)?
This oxygen device can deliver up to nearly 100% FiO₂ when set at 10–15 L/min.
What is a nonrebreather mask?
These structures in the airway prevent food from entering the lungs during swallowing.
What are the vocal cords or epiglottis?
This instrument is used to listen to lung sounds.
What is a stethoscope?
This device uses oxygen flow to create a mist of medication.
What is a small volume nebulizer (SVN)?
This airway is inserted through the nose.
What is a nasopharyngeal airway (NPA)?
The minimum flow required to prevent CO₂ rebreathing in a simple mask.
What is 5 L/min?
The ____ mainstem bronchus is more likely to receive an accidentally advanced ET tube because it is shorter, wider, and more vertical.
What is the right bronchus?
Low oxygen levels in the blood are called this.
What is hypoxemia?
The typical oxygen flow used to run a nebulizer treatment.
What is 6–8 L/min?
This procedure involves placing a tube into the trachea to secure the airway.
What is endotracheal intubation?
This oxygen delivery system provides precise FiO₂ levels using color-coded adapters.
What is a Venturi mask?
Gas exchange occurs in these microscopic structures in the lungs.
What are alveoli?
This sign of respiratory distress involves visible contraction of neck muscles during breathing.
What is accessory muscle use?
This medication is commonly used as a bronchodilator in asthma.
What is albuterol?
This device is used to visualize the vocal cords during intubation.
What is a laryngoscope?
This complication can occur when high oxygen concentrations are given for long periods.
What is oxygen toxicity?
This membrane allows oxygen and carbon dioxide to diffuse between air and blood.
What is the alveolar-capillary membrane?
A bluish discoloration of the skin due to low oxygen levels.
What is cyanosis?
What breath sound is typically associated with needing a bronchodilator?
What is expiratory wheezing?
The most reliable method for confirming ET tube placement.
What is end-tidal CO₂ detection (capnography)?
