Problems solved by technology

[0008] 1. No synchronization between the mechanical cycle delivered by the ventilator and the patient's spontaneous breathing maneuver (eg, mechanical inhalation coincides with spontaneous exhalation, high pressure in the respiratory system)
[0009] 2. Elongation of the trachea due to obstruction and infection
The protocol quickly becomes significantly limiting due to the large number of failed activations caused by the patient's voluntary actions not completing the oxygen delivery
This involves dangerous consequences, starting with hyperventilation that can even lead to brain damage in low-birth-weight newborns

Embodiment Construction

[0057] For a better understanding of the present invention, the mode of operation of the preferred embodiment of the present invention will be described below, and the same mode is also valid for other embodiments.

[0058] The procedure according to the invention provides a specific sub-process allowing to calculate the leakage during supplemental oxygen supply through the nasal cannula. This allows to have an indication of effective airflow to the neonate or patient, thereby confirming control triggering of the same airflow.

[0059]The basic assumption on which the above procedure is based is that there is a physiological interval between the end of exhalation and the start of a new inhalation, during which there is no airflow exchange between the patient and the outside world.

[0060] The main problem with this calculation is that it is not possible to define exactly the end of inspiration because the oxygen supply circuit is open.

[0061] In order to overcome this prob...

Abstract

The present invention concerns a method for nasal ventilation and relevant apparatus, particularly for flow-synchronized neonatal assisted ventilation, wherein F(t) is a signal proportional to the ventilation flow, comprising the following steps: (a) inspiration, having a time length Ti, during which air is introduced at an inspiration pressure; (b) expiration, having a time length Te, during which the introduction of air is interrupted; (c) return to step (a); characterised in that it comprises a flow threshold Ftr, and in that during said expiration step (b) the following steps are provided: (b1) a waiting step having a time length ³ before the activation of the computation of the leakages; and (b2) a step of computation of the leakages, having a time length ´, so that ³+´ =Te, wherein if a normalized signal F'(t), obtained by a processing by means of an algorithm of the surveyed signal F(t), exceeds the threshold Ftr, a spontaneous respiration activity is detected and the inspiration step (a) is reactivated.

Description

technical field [0001] The present invention relates to a method and a related device for supplying nasal cavity oxygen, in particular to a method and a related device for supplemental oxygen supply for newborns synchronized with the airflow. [0002] More specifically, the present invention relates to a method of the above type, in particular to allow mechanical oxygenation of low birth weight neonates (premature infants) by means of an airway prosthesis consisting of two nasal tubes, avoiding tracheal intubation when possible. Background technique [0003] It is well known that low birth weight preterm newborns require a number of therapeutic interventions aimed at stabilizing and ensuring key vital functions, especially respiration. [0004] In fact, respiratory failure is the most common cause of morbidity and mortality in these young patients. [0005] Treatment of moderate-to-severe respiratory failure in premature neonates is achieved by maintaining the patient's spo...
