monitoring
2

Respiratory therapy and management

Requires immediate emergency medical intervention. Do not delay treatment.

procedure
3

Diaphragm pacing implantation

Surgical placement of electrodes on the phrenic nerves to enable electrical stimulation of the diaphragm for respiratory support, offering greater mobility than conventional ventilation.
