1. INTRODUCTION
The mechanical ventilation system LEITAT 1 is a device designed to keep in vital support the
patient in a situation of severe respiratory failure who requires intubation and invasive mechanical
ventilation. It should not be considered as a partial ventilatory support system (non-invasive
mechanical ventilation - NIMV) in patients who ventilate spontaneously. It is not a therapy, it is a
support intervention, a medical device for ventilatory and temporary support therapy that
ventilates the patient while correcting the originating problem.
In its entirety, the device allows to apply a mandatory ventilation mode with a programmable
volume to a patient through the mechanical actuation of a conventional resuscitation balloon
system (AMBU).
The use of this equipment is exclusively for clinical research and only in a hospital setting.

2. INSTALLATION AND SET UP
2.1. GENERAL INFORMATION
LEITAT 1 works as Volume-Controlled Ventilation and mode of operation is mandatory.
In each ventilation cycle, the inspiratory time (in seconds) can be adjusted, allowing the desired
inspiration: expiration (I: E) ratio to be selected.
In normal operating mode, the user can control the number of ventilatory cycles per minute
(respiratory rate), as well as the amount of air blown by controlling the actioning blades. In the
case of detecting a pressure greater than 50 cmH2O, an audible and lighted warning alarm is
activated and, automatically, the operating mode changes from "Volume-Controlled Mode” to
"Pressure-Controlled Mode", maintaining a breath cycle of 1 inspiration for 2 expiration but
applying a volume of air that does not exceed the pressure of 50 cmH2O.
