Diagnosis and Management of Acute Respiratory Failure
4 important questions on Diagnosis and Management of Acute Respiratory Failure
What are clinical manifestations of respiratory distress (4)
- Altered mental status (agitation to somnolence)
- Increased work of breathing (nasal flaring, respiratory muscles, tachypneu, or paradoxical breathing pattern)
- Cyanosis of mucosal membranes (tongue, mouth)
- Persperation, tachycardia, hypertension (catecholamine release)
What is paradoxical inspiration?
Air-Entrainment / Venturi Mask
- 100% oxygen
- FiO2 can be controlled (24% - 50%) by changing the jet nozzle and adjust the flow rate
- Useful for patients with COPD who require a degree of hypoxemia to sustain respiratory drive
High-flow, controlled oxygen
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Aerosol Face Mask
- Nebulizer (=vernevelaar) + 100% oxygen
Moderate flow, variable-oxygen
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
