### 4/5 — You have deactivated the breaths measurement.

*2022-08-12, version 1.9*

Preston 2000 worked fine for 6 months, now when I ventilate I get “You have deactivated breaths measurement.” Compressions work fine.

Recalibrated ventilation same result.  Changed lungs same result.  Changed add-on kit same results. I have current app version 1.9.3.

Any ideas?

### 4/5 — Needs ventilation only mode

*2022-03-03*

Would be nice to have ventilation mode when practicing airway.

### 5/5 — Manikins will not calibrate

*2022-07-31, version 1.9*

i have 4 manikins the app recognizes only 2 and none will calibrate
