A compressor driven by a motor sends to a nasal mask a breathable gas at a low positive relative pressure whereby the motor is controlled to maintain the pressure in the delivery pipe of the compressor substantially equal to a set point, independently of the inspiration and expiration of the patient
A compressor driven by a motor sends to a nasal mask a breathable gas at a low positive relative pressure whereby the motor is controlled to maintain the pressure in the delivery pipe of the compressor substantially equal to a set point, independently of the inspiration and expiration of the patient, a computer receiving on an input a motor speed signal as a parameter representative of the respiratory activity of the patient and analyzing the motor speed variations whereby the computer will increase the pressure set point if necessary or reduces the pressure set point by a predetermined amount depending upon whether there is a hypopnoea or the absence thereof.

The engine fuel-injection control device according to claim 1, wherein said means for calculating a limit fuel-injection amount at startup calculates said limit fuel-injection amount at startup in accordance with said engine cooling water temperature. 3. The engine fuel-injection control device according to claim 1, further comprising: minimum value selecting means that select the smaller of two values that are said additional fuel injection amount at startup, which is calculated by said means for calculating an additional fuel injection amount at startup, and said limit fuel-injection amount at startup, which is calculated by said means for calculating a limit fuel-injection amount at startup. 4. The engine fuel-injection control device according to claim 1, wherein said means for electing a target fuel-injection amount at startup elects said base fuel-injection amount at startup, which is calculated by said means for calculating a base fuel-injection amount at startup, as the current said target fuel-injection amount at startup, irrespective of whether the accelerator has been actuated or not, until a predetermined time has elapsed since initiation of engine startup. 5. The engine fuel-injection control device according to claim 1, wherein said means for calculating a base fuel-injection amount at startup calculates said base fuel-injection amount at startup on the basis of said engine water temperature and rotation speed. 6. The engine fuel-injection control device, according to claim 1, which is applied to a common-rail type diesel engine comprising: a high-pressure supply pump; a common rail for retaining fuel that is conveyed under pressure from said high-pressure supply pump; injectors for injecting fuel supplied from said common rail into engine combustion chambers when an electromagnetic actuator is driven; and a controller for providing the said electromagnetic actuator, at a predetermined time and over a predetermined duration, with a control current for driving the electromagnetic actuator. 7. The engine fuel-injection control device according to claim 6, wherein said means for calculating a base fuel-injection amount at startup, said means for calculating an additional fuel injection amount at startup, said means for calculating a limit fuel-injection amount at startup and said means for electing a target fuel-injection amount at startup are comprised by said controller. 8. An engine fuel-injection control device, comprising: a device for calculating a base fuel-injection amount at startup, which calculates a base fuel-injection amount at startup, at startup of an engine; a device for calculating an additional fuel injection amount at startup, which calculates an additional fuel injection amount at startup by adding a predetermined additional fuel injection amount to a previous target fuel-injection amount at startup; a device for calculating a limit fuel-injection amount at startup, which calculates, on the basis of an accelerator actuation amount, an injectable limit fuel-injection amount at startup that is a boundary value at which smoke
