Final answer:
A disposable oxygen humidifier should be considered for ambulance services that often transport patients on runs longer than 80 minutes. Administering oxygen helps in turning carbon monoxide back into hemoglobin.
Step-by-step explanation:
A disposable oxygen humidifier should be considered for ambulance services that often transport patients on runs longer than 80 minutes. This is because administering oxygen via a non-rebreather mask shortens the half-life of carbon monoxide from 320 minutes to only 80 minutes. Oxygen helps in turning carbon monoxide back into hemoglobin by hastening the dissociation process.
