Final answer:
Without specific details of the MD-1 cylinder's volume and pressure, it's not possible to determine how many minutes of oxygen it would furnish for use.
Step-by-step explanation:
An MD-1 emergency oxygen cylinder would furnish an approximate volume of O2 based on its capacity and the pressure it's stored. However, the question as presented does not provide specific details such as the volume of the cylinder, the pressure at which the oxygen is stored, or the flow rate at which the oxygen would be used. Therefore, it's not possible to give a precise number of minutes without this information.
Mountain climbers use bottled oxygen at high altitudes, for instance, and the calculable usage for a climber can involve mathematical physics and human biology factors like the metabolic rate. These figures can then be used to deduce the duration an oxygen cylinder would last; noting that only a percentage of inhaled oxygen is used by the body, and the rest is exhaled. This presents a multidisciplinary problem involving chemistry, biology, and physics.
