Some real-life events, such as the assassination of a top-ranked Iranian general, are also referenced in the game. The game takes place in a variety of settings including the US-Mexico border, Mexico Gulf, Chicago, and the fictional city of Las Almas. The plot follows the multinational spec ops unit Task Force 141 as they gain support from various allies such as the CIA and Russian militias in their hunt for an extremely dangerous terrorist known as major Hassan Zyani. Moreover, the Mexican Special Forces unit Los Vaqueros will also be aiding Task Force 141 in their hunt.Īlthough released with the same name, the 2022 Modern Warfare II is not a remake of the 2009 classic but rather a continuation of the 2019 Modern Warfare. Fan-favorite characters such as Captain Price, Soap, Gaz, and Ghost make a return and this time around, they have to deal with Hassan Zyani, a major terrorist working for the Iranian Quds Force. The newest installment in the critically-acclaimed series, Call of Duty: Modern Warfare II, brings a new storyline while maintaining the nostalgic value with its incorporation of Taskforce 141 alongside certain other characters.

Q – perfusion – the blood that reaches the alveoli via the capillaries.V – ventilation – the air that reaches the alveoli.Time constant is proportional to by resistance and compliance.In respiratory physiology, the ventilation/perfusion ratio ( V/Q ratio) is a ratio used to assess the efficiency and adequacy of the matching of two variables: the time required to inflate the lung unit if the flow rate is constant throughout.the time required to inflate to 63% of final volume if inflation is prolonged indefinitely.Time constant Definition of time constant NB: Normal tidal breathing is about 0.5L/sec => ventilation of apex:base = 1:1 or 1+:1 fast inspiration (flow rate > 1.5 L/sec) from FRC.during slow inspiration from residual volume.In anaesthetized patients, better ventilation in upper side. Alveoli on dependent side is less expanded.Diaphragm on the lower side is higher and thus contract better.Right lung ventilates better than left, because of its larger size.īetter ventilation on dependent side because: Right vs left lung Supine or erect position Thus, lung base is only ventilated intermittently in emphysema. => during inspiration, intrapleural pressure at lung base take a while to become negative and airflow occurs => at base, intrapleural pressure may even become positive => intrapleural pressure becomes less negative Where the elastic recoil of lung is reduced (e.g. Only the first part of inspired gas goes preferentially to apex. => initially, apex will expand first before intrapleural pressure at base becomes negative and air flows into base. Lung volume and recoil Very low lung volumeĪt very low lung volume (lower than closing capacity),īecause the lung base is so compressed that intrapleural pressure becomes positive,īecause small airways at base are closed, compliance at base is more optimal and is higher than apex.
