An increase in volume DECREASES the pressure in the chest (pressure and volume vary inversely when temperature is held constant -- Boyle's law). Gas can only flow from an area of higher pressure to an area of lower pressure. It can't go uphill -- ever. It can only go from high to low pressure. When the diaphragm and intercostals contract, the diaphragm flattens and the rib cage rises. That increases the volume of the chest. That increase in volume decreases the pressure inside the chest (temperature is held constant -- because the temperature of the chest cavity does not change appreciably. It remains at body temp.). Air then flows from the area of higher pressure (atmospheric) to lower pressure (intrathoracic). That continues until the pressures are equal.
When the diaphragm and intercostals relax, the chest cavity decreases in size, the pressure increases to above atmospheric, and gas flows again from the area of higher pressure (intrathoracic) to lower pressure (atmospheric) until they are again equal.
It has nothing to do with the concentration of oxygen. You can ventilate a lung with ANY gas. It has to do with the change in pressure and only the change in pressure -- which is a function of the volume of the chest cavity.

Explanation:
Confidentiality and privacy in health care system is very important. All the medical records and information about the patient's medication and diseases concerned should be kept secret. By law of any nation, this is extremely important.
It is understandable to keep the medical records and history of Vivian Armand tests and lab reports secret because as per law the medical professionals and nurses should keep the information private.
Keeping secrecy of medical records is advantageous because it is the right an individual to have his/her health records to be private. If by any means it is found that the privacy has been compromised by any health care professional, it should be reported to the doctor.
