Respiratory Medicine — Flashcards
On this page
_____ helps to prevent airway collapse, improves ventilation and reduces atelectasis in patients who require respiratory support
Mechanical ventilation is used when other respiratory support is inadequate. Patients usually _____ require sedation.
_____ is the most extreme respiratory support only used VERY RARELY when intubation with ventilation is not adequate
_____ provides a higher pressure during inspiration AND a lower pressure during expiration
Hint: Type of pressure support
Oxygen therapy in type 2 respiratory failure should be started at a _____ FiO2 as they may be insensitive to CO2 and respiration could be driven by hypoxia
Hint: Higher/Lower
What are the different types of oxygen therapy? _____ - 24-44% FiO2 Simple face mask - 40-60% FiO2 Venturi mask - 24-60% FiO2 Non-Rebreather mask - 60-95% FiO2
Both type 1 & 2 respiratory failure are managed with _____ and by treating the underlying cause
What are the different types of respiratory pressure support (least → most invasive)? _____ CPAP NIV (BiPAP) Mechanical ventilation
What pathophysiological mechanisms cause type 1 respiratory failure? _____, abnormal diffusion, right to left cardiac shunts, low inspired oxygen tension (low FiO2)
Hint: Most common
What pathophysiological mechanism causes type 2 respiratory failure? _____ with or without V/Q mismatch
