Problems solved by technology

Since volatile anesthetic agents are expensive and environmentally damaging to the atmospheric ozone layer, anesthesia machines have been developed to minimize the use of these gases.
The volume going to the patient, if any, is not possible to determine haptically by how much the bag is squeezed.
It is not possible to deliver a PEEP (Positive End Expiratory Pressure) to the patient with the APL valve.
Yielding from this, the Berner valve involves a safety problem related to every manual breath: Would t...

Embodiment Construction

[0021]Specific embodiments are explained in the following detailed description making a reference to accompanying drawings. These detailed embodiments can naturally be modified and should not limit the scope of the invention as set forth in the claims.

[0022]The embodiments are directed to a system and a method for a use in an intensified breathing, and for a use whenever anesthesia is being delivered to a subject.

[0023]The system 10 for providing an inspiration gas to the subject 12 utilizing a re-breathing system is shown in FIG. 1. The system 10 comprises a machine ventilator circuit 14 for assisting breathing functions of the subject, a breathing circuit 16 for connecting lungs of the subject and the machine ventilator circuit 14 to exchange the gas in the lungs, a manual ventilation circuit 18 for enabling the manual ventilation of the subject and a control unit 21 for controlling an operation of the system 10. The manual ventilation circuit 18 and the machine ventilator circuit...

Abstract

A system for ventilating lungs of a subject is disclosed herein. The system includes a control unit configured to control operation of the system. The system also includes a machine ventilator circuit configured to assist the breathing functions of the subject, the machine ventilator circuit includes an inspiration delivery unit, and an expiration circuit. The system also includes a manual ventilation circuit comprising a manual bag guiding a gas from the manual bag wherein a gas flow is guided out from the manual bag to assist an inspiration phase, a gas flow is received to fill the manual bag during an expiration phase, and wherein the gas flow received to fill the manual bag during the expiration phase at least partially comprises the gas flow guided to assist the inspiration phase

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The field of the invention relates generally to a system and method for ventilating lungs of a subject that enables the selection of one of a machine ventilation for assisting breathing functions and a manual ventilation with a manual bag which can be compressed for an inspiration.[0003]2. Description of the Prior Art[0004]Presently, anesthesia machines are optimized for delivering anesthesia to a patient using volatile anesthetic agent liquids. In such systems, the anesthetic agent is vaporized and mixed into the breathing gas stream in a controlled manner to provide a gas mixture for anesthetizing the patient for a surgical operation. The most common volatile anesthetic agents are halogenated hydrocarbon chains, such as halothane, enflurane, isoflurane, sevoflurane, and desflurane. Additionally, nitrous oxide (N2O) can be counted in this group of volatile anesthetic agents, although the high vapor pressure of nitrous ...
