sfm3x00-ventilation-monitor
wayland/sfm3x00-flow-meter/sfm3x00-ventilation-monitor
Node for monitoring ventilation using sfm3x00. Measures flow rate, respiratory rate, inspiratory/insufflation volume and expiratory/exsufflation volume. End of inspiratory and expiratory phases are indicated by a pulse from INS and EXP, respectively.

I²C bus
RSTpulse
Reset. Triggers soft reset and reinitialisation of sensor.
UPDpulse
Update
DONEpulse
Pulse on read.
EXPpulse
Pulse on end of expiration (start of inspiration).
INSpulse
Pulse on end of inspiration (start of expiration).
eVOLnumber
Expiratory/exsufflation volume (cubic centimetres).
iVOLnumber
Inspiratory/insufflation volume (cubic centimetres).
RRnumber
Respiratory rate (breaths per minute).
FRnumber
Flow rate (standard litre per minute). Inspiration/insufflation results in a positive flow. Flow is negative during expiration/exsufflation.
