SEPARATION OF MECHANICAL VENTILATION

Abstract

The weaning from mechanical ventilation can be defined as the process of letting the
ventilator either directly or in stages. Indication of weaning from mechanical
ventilation, seen from several parameters such as disease processes, PaO2, PEEP,
FiO2, pH, Hb, awareness, body temperature, cardiac function, lung function, drugs
sedative agent or paralysis agent, and psicologic status of patient. Based on the
length of the weaning, can be devided into two, long-term weaning dan short-term
weaning. Short-term weaning, such as T-Piece, CPAP, SIMV, and PSV. Long-term
weaning, such as T-Piece and Intermitten Mandatory Ventilation. There are two that
affect the length of weaning, such as nonventilator factor and ventilator factor.
Nonventilator factor such as sedation drug abuse, malnutision, lack of psychological
support, and lack of support if there is damage to the left ventricle. Ventilator factor
such as over ventilation and under ventilation. Factor that lead to failure in weaning
affected by respiratory control center, respiratory muscle strength, and load on the
respiratory muscles.
