Current perspectives in oxygenation and ventilation--Part II.

Abstract

This is the second part of the discussion on current perspectives in oxygenation and ventilation. The focus is on modes of ventilation. Intended goals of ventilation therapy are discussed, particularly in relation to work of breathing and oxygen delivery. Current modes of ventilation are reviewed, with advantages and disadvantages of the types of therapy presented in summary tables. Consideration is given to the broader perspective of ventilation therapy, that is, improving the balance between oxygen delivery and tissue oxygen needs. Optimizing the oxygen balance includes nursing interventions directed toward decreasing oxygen demands.
