Rebreathing vs non rebreathing mask- are they both same??

Nonrebreathing reservoir mask Exception - one-way valve at the exit of the reservoir bag. Enabling delivery of 100% oxygen One-way valves on its side ports to minimize the inhalation of ambient air. Maximum FiO2 upto 90% good temporizing measure in an acutely hypoxemic patient #mneumonic #rebreather #mask #nrbm #oxygen #cannula #delivery #fio2 #highflow #lowflow #respiration #neet #plab1 #chest #hypoxia #hypercapnea #mrcp #icu #critical #care Disadvantage Typically, these masks provide a FiO2 may be even lower (0.60–0.8) in the setting of very high minute ventilation/ respiratory distress Mask tightly sealed on face Risk of CO2 retention if oxygen flow dysfunction Amount of O2 cannot be titrated to target O2 saturation and could theoretically expose patients to hyperoxia Use of NRBM Carbon monoxide poisoning Smoke inhalation Chronic airway limitation Cluster Headache Patients who require high-concentration oxygen, but do not require breathing assistance. Claustrophobia
