Embodiment Construction

[0033] figure 1A respirator 1 according to the invention is shown with a neonatal or pediatric patient 2 ventilated by means of an endotracheal tube 3 . A breathing mask can also be used as an alternative to the endotracheal tube 3 . Such as figure 1 and figure 2 As shown, electric wires are represented by a single line and pneumatic lines are represented by a double line. The ventilation takes place via two breathing tubes 4 and 5 , wherein the premature infant 2 is supplied with fresh air for inhalation via the breathing tube 4 and the exhaled air is exhausted via the breathing tube 5 . This prevents carbon dioxide from building up in the breathing tube.

[0034] If the ventilator 1 is used in an intensive care unit, it is usually connected to a hospital gas supply, represented by an oxygen cylinder 12 and a gas cylinder 15 , for example. However, the gas cylinder may also be physically present and placed outside the respirator, or, where properly designed, inside th...

Abstract

The invention relates to a respirator comprising a breathing tube connection for connecting a breathing tube; an actuator pneumatically connected to the breathing tube connection for delivering air to a patient via the breathing tube connection; providing a breathing sensor with a breathing sensor signal Breathing sensor connector and digital programmable controller. The controller calculates the inhalation volume based on the breathing signal, and calculates the inhalation volume and exhalation volume based on the lung volume signal for each breath. The controller is also used to determine when the exhaled volume exceeds the associated inhaled volume by an adjustable value, increasing the pressure at the end of exhalation. When oxygen saturation drops below the lower limit, increase the pressure at the end of exhalation. It is determined whether the oxygen saturation has dropped below the lower limit, and if so, backup ventilation is initiated at a predetermined frequency. When the oxygen saturation exceeds the lower limit again, reduce the backup ventilation frequency. In another embodiment, backup ventilation is terminated when the oxygen saturation exceeds the average limit. The invention also relates to a corresponding control method.

Description

technical field [0001] The field of the invention includes respirators of the type mentioned in the preambles of claims 1 , 3 , 5 and 7 , and control methods of the type mentioned in the preambles of claims 10 , 12 and 15 . [0002] EP 2091429 B1 discloses a respirator according to the preambles of claims 1 and 9 . [0003] The present invention relates to the field of respirators and control methods thereof, in particular to respirators considering the oxygen saturation in blood measured by an oximeter. Background technique [0004] It is well known that mechanically ventilated respirators produce various forms of oxygen deficiency. (Roche Lexikon Medizin, 4 th ed., Urban & Fischer Verlag, Munich). This type of respirator is also known as a ventilator. There are three basic types: [0005] a) Pressure-controlled respirators: the inspiratory phase is terminated when a predetermined breathing pressure is reached in the device. Exhalation is mostly passive. [0006] b)...
