Verdict

The call

The clearest difference is price: Ventilator Guide at Free against Respiratory Assistant's $3.99. Ventilator Guide also leads on iOS requirement (11.0 vs 13.0). Respiratory Assistant's advantage is update cadence (every 3 weeks vs every 30 months) and chart position (#196 vs unranked).
