Inhaled Nitric Oxide for Cardiac Arrest in Pediatrics and Adults (iNOCAPA)

In patients randomized to the this arm, iNO will be delivered into the ventilator circuit through the endotracheal tube or tracheostomy. The dose will be 80 ppm during chest compressions and reduced to 20 ppm immediately following ROC. If the patient is enrolled following ROC, the dose will be 20 ppm. Dose modifications will occur if there is toxicity or if there is a clinical concern. The iNO or sham will be continued for 72 hours or until extubation.

In patients randomized to sham, the iNO delivery device will be connected to the ventilator circuit or manual ventilation bag but flow of iNO will not be turned on. For the purposes of patient safety and to maintain blinding, the respiratory therapists (RTs) will continue checks of gas flow, flow adjustments and change iNO gas tanks at rates like routine clinical procedures on patients treated with iNO or sham.
