Published	08/28/2024	In an upright position, the largest alveoli are at the {{c1::apex}} of the lung.
Published	08/28/2024	At end-expiration, intrapleural pressure is {{c1::-5}} cm H2O.
Published	08/28/2024	Distended alveoli {{c1::reduces}} surfactant concentration, leading to a {{c2::increase}} in surface tension.
Published	08/28/2024	Closing capacity:The volume at which {{c1::small airways}} begin to close in {{c1::dependent (basen)}} areas of the lung.
Published	08/28/2024	In normal, young patients, the closing capacity is {{c1::less}} than the FRC.
Published	08/28/2024	In {{c2::elderly}} (CC stiger) and {{c2::obese}} patients (FRC minskar), the closing capacity is {{c1::more}} than the FRC.
Published	08/28/2024	Dead space from {{c2::conducting airways}} is known as {{c1::anatomic dead space}}.
Published	08/28/2024	Shunt is {{c1::perfusion}} without {{c1::ventilation}}.
Published	08/28/2024	At the base of the lung, pleural pressure is {{c2::less negative (större)}}, so the transpulmonary pressure is {{c1::smaller::bigger/smaller}}.
Published	08/28/2024	During a pneumothorax, the transpulmonary pressure becomes {{c3::zero}}, causing the lungs to {{c1::collapse}} as a result of {{c2::elastic recoil}}.&…
Published	08/28/2024	How does positive pressure, such as CPAP, affect FRC?{{c1::Increased due to decreased atelectasis}}
Published	08/28/2024	PEEP is applied {{c1::at end-expiration}}, while CPAP is applied {{c2::continuously}}.
Published	08/28/2024	PEEP/CPAP will increase {{c1::FRC::lung volume}}.
Published	08/28/2024	Excessive PEEP/CPAP increases {{c2::right ventricular afterload}} by compressing {{c1::alveolar capillaries}}.
Published	08/28/2024	How can excessive PEEP/CPAP affect intracranial pressure?{{c1::May increase ICP}}
