title: Intermittent mandatory ventilation. A method to expand clinical applications.
abstract: The described modification of the Cameco URS-701 ventilator increases the frequency possibilities from zero to 40, without interfering with the ventilator pattern of each cycle and satisfies the required conditions for a classical IMV-system. Moreover it can provide longer periods of controlled ventilation alternating with periods of spontaneous respiration. This adaptation, mainly consisting of the introduction of a timer in the electrical circuit of the machine, provides us with a safe IMV system on our Engstrom 150 type ventilator and leads to a broader concept of IMV.
