摘要：
System and method for monitoring respiratory quantities during the administration of oxygen at various concentrations by nasal cannulas, in particular by means of an HFNC (High Flow Nasal Cannula) apparatus (100) or a CPAP (Continuous Positive Airway Pressure) apparatus (200), which system and method provide the use of: - a first flow detector (21 or 1021, DPT-A) configured to measure a delivered flow (ΦHFNC_PNT-A or ΦΟΡΑΡ_ΙΠ_ΡΝΤ-Α) of oxygen at different concentrations administered upstream the nasal cannulas (105 or 205)； - a second flow detector (22 or 1022, DPT-B) configured to measure a residual flow (ΦMask_PNT-B or ΦΟΡΑΡ_out_ΡΝΤ-Β) that crosses an oro-nasal mask (3) worn above the nasal cannulas (105) of an HFNC apparatus (100) or expiratory branch (206) of the ventilation circuit in the case of a CPAP apparatus (200)； - a pharyngeal catheter (4) associated with a pressure transducer (DPT-D) for measuring pharyngeal pressure (Pphar)； - an esophagus-gastric catheter (5) associated with two pressure transducers (DPT-E, DPT-F) for measuring the esophageal pressure (PEs) and gastric pressure (PGa)； - a catheter associated with a pressure transducer (DPT-C) configured to measure the internal pressure of the oro-nasal mask (3) (PMask) or a circuit catheter (1006) associated with a pressure transducer (DPT-C ) configured to measure the pressure inside the ventilation circuit near the nasal cannulas (205) (PCirc)； - an oscilloscope (7)； - a processing unit (10 or 1010) for the determination of parameters representative of respiration and/or pulmonary mechanics.
