Abstract
Various methods and systems are provided for a ventilation system. In one example, a method for operating a ventilation system in a manual ventilation mode includes activating an electronically-controlled valve and a pneumatically-controlled valve to provide a pilot pressure to the pneumatically controlled valve to deliver a target positive end expiratory pressure (PEEP) from a gas control unit during expiration. The method further includes adjusting the pilot pressure based on a comparison of a patient airways pressure to the target PEEP for each breath of a patient.
Claims20
A method for operating a ventilation system in a manual ventilation mode, comprising:
- activating an electronically-controlled valve and a pneumatically-controlled valve to provide a pilot pressure to the pneumatically-controlled valve to deliver a target positive end expiratory pressure (PEEP) from a gas control unit during expiration;
- adjusting the pilot pressure based on a comparison of a patient airways pressure to the target PEEP.
A ventilation system, comprising:
- a pneumatically-controlled valve arranged in a path of pilot gas flow between a bag and a scavenging circuit of the ventilation system, the pneumatically-controlled valve adjusted based on a pilot pressure directed thereto by an electronically-controlled valve to provide a positive end expiratory pressure (PEEP) to a patient during manual ventilation of the patient.
A method for a ventilation system, comprising:
- responsive to adjustment of the ventilation system to operation in a manual ventilation mode;
- flowing a pilot gas from an electronically-controlled three-port, two-way (TPTW) valve to a pneumatically-controlled pressure relief valve (PRV) during an expiration cycle to deliver a positive end expiratory pressure (PEEP) to a patient;
- and
- responsive to adjustment of the ventilation system to operation in a mechanical ventilation mode;
- blocking a flow of the pilot gas to the pneumatically-controlled pressure relief valve and maintaining the PEEP based on a PEEP setting of the manual ventilation mode.
