Calc Rdos

x402 APIPassing, checked 4 h ago

Campbell 2010 RDOS for patients unable to self-report dyspnea. Eight caller-assigned 0-2 integers (heart_rate, respiratory_rate, restlessness, paradoxical_breathing, accessory_muscle_use, grunting, nasal_flaring, look_of_fear). magent sums only (max 16); does not convert raw heart or respiratory rate or observe the patient. Campbell 2010 published the 0-16 instrument; magent does not apply later cutoff papers. Not a medical device and not an opioid or oxygen order.
