Ambient pressure control ventilation apparatus and method

Abstract

An ambient pressure control ventilation apparatus for mechanical ventilation of a patient comprising a sealable chamber adapted to accommodate a whole body of a patient, a pump fluidly connected to the chamber adapted to alternatively compress and decompress a ventilating gas within the chamber, a relief valve fluidly connected to the chamber and a control unit adapted to control the pump and the relief valve to facilitate a periodic regime of alternating compression and decompression of the ventilating gas within the chamber about a predetermined baseline.

1 . An ambient pressure control ventilation apparatus for mechanical ventilation of a patient comprising: 
 a sealable chamber adapted to accommodate a whole body of a patient,    a pump fluidically connected to said chamber adapted to alternatively compress and decompress a ventilating gas within said chamber;    a relief valve, fluidically connected to said chamber; and    a control unit adapted to control said pump and said relief valve so as to facilitate a periodic regime of alternating compression and decompression of said ventilating gas within said chamber, about a predetermined baseline.    
   
   
       2 . The apparatus as claimed in  claim 1 , wherein said ventilating gas is a mixture of air and oxygen.  
   
   
       3 . The apparatus as claimed in  claim 1 , wherein said ventilating gas is oxygen.  
   
   
       4 . The apparatus as claimed in  claim 1 , said apparatus further comprising at least one pressure sensor within said chamber, said at least one pressure sensor communicating with said control unit so as to allow said control unit to determine the pressure condition within said chamber.  
   
   
       5 . The apparatus as claimed in  claim 4 , wherein said control unit is further adapted to prevent pressure drop within said chamber below a predetermined oxygen partial pressure value.  
   
   
       6 . The apparatus as claimed in  claim 5 , wherein said predetermined pressure value is 0.25 atm.  
   
   
       7 . The apparatus as claimed in  claim 1 , wherein said baseline ranges between 0.5 atm. and 1.5 atm.  
   
   
       8 . The apparatus as claimed in  claim 1 , wherein said control unit is adapted to control said pump and said relief valve so as to facilitate a periodic regime of alternating compression and decompression of said ventilating gas within said chamber, about a predetermined baseline, within a predetermined pressure range of the baseline plus 170 mm Hg to the baseline minus 170 mm Hg.  
   
   
       9 . The apparatus as claimed in  claim 1 , wherein said control unit is adapted to control said pump and said relief valve so as to facilitate a periodic regime of alternating compression and decompression of said ventilating gas within said chamber, about a predetermined baseline, within a predetermined pressure range of between the ambient barometric pressure to the ambient barometric pressure plus 175 mm Hg.  
   
   
       10 . The apparatus as claimed in  claim 1 , wherein said chamber is transportable.  
   
   
       11 . The apparatus as claimed in  claim 10 , wherein said chamber is provided with wheels for transportation.  
   
   
       12 . The apparatus as claimed in  claim 1 , wherein said chamber is essentially made of non-compliant transparent plastic material.  
   
   
       13 . The apparatus as claimed in  claim 1 , wherein said chamber is provided with a door adapted to allow quick bringing in and taking out of a patient.  
   
   
       14 . The apparatus as claimed in  claim 13 , wherein said door can also be opened and closed from within said chamber.  
   
   
       15 . The apparatus as claimed in  claim 1 , wherein said chamber is provided with a sealable opening adapted to allow quick access of a nursing team to the airway and chest area of said patient.  
   
   
       16 . The apparatus as claimed in  claim 1 , wherein a bed is provided in said chamber for the patient to lie on.  
   
   
       17 . The apparatus as claimed in  claim 1 , wherein said chamber is provided with a communication block that is adapted to facilitate linking of devices positioned within said chamber to said control unit or other devices.  
   
   
       18 . The apparatus as claimed in  claim 17 , wherein monitoring lines from sensors placed in an endotracheal tube within the airway of the patient are connected via said communication block to said control unit.  
   
   
       19 . The apparatus as claimed in  claim 1 , wherein a reserve oxygen balloon is provided for emergency cases.  
   
   
       20 . The apparatus as claimed in  claim 1 , wherein said chamber is further provided with a highly compliant breathing bag that is designed to be connected to the airway of the patient.  
   
   
       21 . The apparatus as claimed in  claim 1 , wherein said pump is electrically connected to the main electric supply.  
   
   
       22 . The apparatus as claimed in  claim 1 , wherein a reserve battery adapted to supply electricity to said pump is provided for cases of emergency.
