Which is the best treatment for type IV respiratory failure?
Correct Answer: Intubation with mechanical ventilation
Description: Type IV respiratory failure occurs due to hypo-perfusion of respiratory muscles in patients with shock. Normally respiratory muscles consume <5% of total cardiac output and oxygen delivery. Patients in shock may have as much as 40% of cardiac output distributed to respiratory muscles. Intubation and ventilator-assisted breathing will allow re-distribution of cardiac output Non-invasive ventilation with tight-fitting face mask is used in the management of Type 2 Respiratory failure e.g. in cases of exacerbations of COPD.
