  • What is airway management?

    Airway management involves techniques to ensure an open pathway for air to enter and exit the lungs.

  • Define respiration in physiology.

    Respiration is the process of gas exchange between the body and the environment, primarily oxygen intake and carbon dioxide removal.

  • What is ventilation?

    Ventilation is the mechanical process of moving air in and out of the lungs.

  • Explain oxygenation.

    Oxygenation is the process of adding oxygen to the body’s tissues via the bloodstream.

  • Why is airway patency important?

    Maintaining airway patency ensures unobstructed airflow for effective breathing and oxygen delivery.

  • Name a common method to secure an airway.

    Endotracheal intubation is a common method to secure the airway and maintain ventilation.

  • What role does the diaphragm play in ventilation?

    The diaphragm contracts to increase thoracic volume, causing air to flow into the lungs during inspiration.

  • Describe the difference between ventilation and respiration.

    Ventilation is air movement; respiration is gas exchange at the cellular level.

  • What is hypoxia?

    Hypoxia is a condition where tissues receive insufficient oxygen.

  • How does oxygenation affect cellular metabolism?

    Proper oxygenation is essential for aerobic metabolism and energy production in cells.

  • What is the primary muscle involved in breathing?

    The diaphragm is the primary muscle responsible for breathing.

  • Define tidal volume.

    Tidal volume is the amount of air inhaled or exhaled during normal breathing.

  • What is the significance of oxygen saturation?

    Oxygen saturation measures the percentage of hemoglobin bound with oxygen in the blood.

  • Explain the term 'ventilation-perfusion ratio'.

    The ventilation-perfusion ratio compares air reaching alveoli to blood flow in pulmonary capillaries.

  • What happens during airway obstruction?

    Airway obstruction blocks airflow, reducing oxygen delivery and causing respiratory distress.

  • Name a sign of inadequate ventilation.

    Signs include rapid breathing, use of accessory muscles, and cyanosis.

  • What is the role of the epiglottis in airway management?

    The epiglottis prevents food and liquids from entering the airway during swallowing.

  • How does positive pressure ventilation assist breathing?

    It forces air into the lungs when spontaneous breathing is insufficient.

  • What is the normal respiratory rate for adults?

    Typically 12 to 20 breaths per minute.

  • Why is monitoring oxygenation important in patient care?

    It ensures tissues receive adequate oxygen to prevent hypoxia and organ damage.
