When Whitney had an asthma attack, oxygen was delivered through a face mask. When patients are administered low flow nasal O 2, the oxygen flow rates are typically between 2-10 liters/minute (L/M).Spontaneously breathing patients typically have an inspiratory flow rate (IFR) of 20-40 L/M. HFNC can provide high-flow gas at a rate of 8-80 L/min, meeting the respiratory requirements of patients with asthma. The O2P is currently the smallest and lightest 1-liter portable oxygen concentrator. Since the lung tidal volume or capacity of a person's lung taken for every breath at the most is about 1/2 liter or 500ml of air, I believe a. . This is why they are often referred to as MC (medium concentration) masks, as 40%-60% is considered to be a medium concentration of oxygen.
