Understanding the ROX Index: When is HFNC Enough?

Please note: exam questions are subject to change.

1. What is a notable advantage of high flow devices? Limited accessibility Inability to provide precise FiO2 Meeting or exceeding the patient's peak inspiratory flow Restricted use in clinical environments
2. In which scenario would a high flow oxygen system be particularly beneficial? Long inspiratory time Low tidal volume Slow rate of breathing Fast rate of breathing
3. What is one of the benefits of HFNC in terms of respiratory physiology? Eliminating humidification Increasing dead space Providing positive end-expiratory pressure Reducing oxygen concentration
4. For pediatric patients, HFNC is often employed in the management of which respiratory conditions? Sickle cell anemia Gastroesophageal reflux disease (GERD) Attention deficit hyperactivity disorder (ADHD) Asthma, bronchiolitis, pneumonia
5. What is a critical factor in the progression and weaning of HFNC that requires clinical knowledge? Patient age The type of oxygen source Expertise of the respiratory therapist Room temperature
