Abstract: Some embodiments of the present invention disclose a method to reduce the intracranial cerebral blood pressure in a newborn, comprising: mounting an inflating cuff in at least one extremity of said newborn; monitoring the blood pressure in said newborn; if blood pressure rises above a predetermined value, then: inflating said inflating cuff to a predetermined level; wherein said inflating cuff further comprises blocking venous blood flow in said extremity by means of said inflating cuff and lowering cardiac output and systemic blood pressure.

Abstract: A high-frequency fan ventilator having a rotating fan fixed via its central shaft to the base of a ventilator chamber. The chamber has separate openings for incoming pressurized air/oxygen and other openings for expelling exhaled gas rich with carbon dioxide originating from the lungs. Using the high-frequency fan ventilator, gas exchange between the lungs and the atmosphere is achieved by rotation of the fan. This rotation creates a negative pressure zone around the fan's center and leads to helical gas waves moving towards the fan's center (away from the lungs), simulating expiration of gas from the lungs. The rotation of the fan's arms also produces helical gas waves directed from the fan, to the periphery of the chamber and towards the lungs through the connector of the ventilation chamber and the endotracheal tube, which is inserted into the trachea, simulating inspiration of gas into the lungs.

Abstract: Intratracheal pulmonary ventilation is introduced to the distal end of an endotracheal tube by one or more intratracheal pulmonary ventilation tubes located in the wall of an endotracheal tube. The direction of flow of the intratracheal pulmonary ventilation is directed away from the distal end of said endotracheal tube, towards the proximal end of said endotracheal tube. The flow through the intratracheal pulmonary ventilation tube reduces the amount of carbon dioxide by replacing the gas located between the distal end of the endotracheal tube and the proximal end of the endotracheal tube where the endotracheal tube is connected to an artificial ventilation system.
