| Node | Description |
|---|---|
| example-flow-meter | Patch to test sfm3x00-flow-meter. The sfm3x00-flow-meter can be reset by sending a pulse to the RST input. Run in debug mode and use the tweak node to send a pulse to the RST input. |
| example-insufflation-monitor | Patch to test sfm3x00-insufflation-monitor. Run in debug mode. |
| example-show-sensor-details | Patch to test sfm3x00-about node. Run in debug mode. Article number, serial number, offset and scale factor should be reported. |
| example-flow-volume-meter | Patch to test sfm3x00-flow-volume-meter. Run in debug mode. |
| example-ventilation-monitor | Patch to test sfm3x00-ventilation-monitor node. Run in debug mode. |
| sfm3x00-about | Reports the following information about a SFM3x00 sensor: article number, serial number, offset and scale factor. |
| sfm3x00-flow-volume-meter | Measurement of flow and volume using SFM3x00. This node is designed for use with a ventilator. It does not detect inspiration or expiration, but relies on a pulse to the RVol input to reset volume measurements at the start of each breathing cycle. |
| sfm3x00-insufflation-monitor | Node for monitoring insufflation/inspiration using sfm3x00. Measures flow rate, respiratory rate and insufflation volume. Beginning and end of insufflation are indicated by pulses from Start an End outputs. |
| 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. |
| sfm3x00-flow-meter | SFM3x00 flow meter. |
