Which condition decrease tidal volume?
Tidal Volume
Tidal volume is a measure of the amount of air a person inhales
during a normal breath. Traditional preset tidal volumes higher
than 10 ml/kg have been proved to be associated with increased risk
of pulmonary barotrauma and should be avoided. High tidal volumes
also decrease venous return and reduce cardiac output. For patients
with no significant lung disease, such as patients who have
experienced drug overdose or trauma, a maximum tidal volume of 10
ml/kg should be used for mechanical ventilation. Recent studies
have shown decreased mortality with the use of lower tidal volume
in patients with acute lung disease. Therefore, patients with an
acute lung disease such as pneumonia, ARDS, fibrotic lung disease,
or COPD should be ventilated with tidal volumes of 6–8 ml/kg.
