Function Description Oxylog 1000 Components of the The Oxylog 1000 comprises the following components: Oxylog 1000 – Pressure reducer – ON/OFF switch – Inspiratory/expiratory switching valve – Minute volume control valve – Frequency control – Safety valve – Emergency air valve –...

Oxylog 1000 Function Description Figure 2 Block diagram of the Oxylog 1000 5503.400...
The compressed gas is supplied from the central supply system (CS) or from an O cylinder with pressure regulator. The operating pressure of the Oxylog 1000 is between 2.7 bar and 6 bar. CAUTION Risk of damage to equipment! Dust, oil and humidity in medical gases may impair the functioning of the equipment or damage it.
Oxylog 1000 Function Description Frequency Control When the unit is off, driving gas flows via the manifold and through the dosage valve D2 to the 3/2-way valve DMR5 and to DMR6. In consequence, DMR6 switches through and the switching valve WV1 switches to expiration.
Function Description Oxylog 1000 Air Mix/No Air Mix The setting of the Air Mix/No Air Mix selector switch determines the O con- Selector Switch centration of the supply gas for the patient. When the Air Mix/No Air Mix selector switch is set to "Air Mix", the injector (I) takes in ambient air through the 3/2-way valve (WV2).
The display range is -10 mbar to 80 mbar. 3.4.3 Emergency Air Valve The spontaneously breathing patient can breathe in ambient air through the emergency air valve if the Oxylog 1000 has failed due to a fault. 5503.400...

Function Description Oxylog 1000 Pressure Sensor During ventilation, the pressure sensor controls and switches the stenosis and disconnection of the patient. The pressure sensor comprises two diaphragms. The ventilation pressure acts on the undersides of the diaphragms. The supply pressure (Insp.) is cen- tered on the craters on the pressure sensor during the inspiration phase.
The compressed gas is supplied from the central supply system (CS) or from an O cylinder with pressure regulator. The operating pressure of the Oxylog 1000 is between 2.7 bar and 6 bar. CAUTION Risk of damage to equipment! Dust, oil and humidity in medical gases may impair the functioning of the equipment or damage it.
When the unit is switched off, valve WV1 and switch S1 are closed. No venti- lation is carried out and there is no pressure at the frequency control. If Oxylog 1000 is switched on using switch S1, the gas flows through switch S1 and manifold VL1 to DMR1 and DMR2 of the frequency control.
