Impairing alveolacapillary membrane diffusion. The major mechanisms that drive pulmonary ventilation are atmospheric pressure (P atm); the air pressure within the alveoli, called intra-alveolar pressure (P alv); and the pressure within the pleural cavity, called intrapleural pressure (P ip). Start studying Chapter 12 Pulmonary Structure and Function. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Pulmonary Function Tests . 15. Edited by J.M.B.

Initial data gathering and interview... 2. This review provides an overview of the relationship between ventilation/perfusion ratios and gas exchange in the lung, emphasising basic concepts and relating them to clinical scenarios. Select the correct statement about the physical factors influencing pulmonary ventilation. Pulmonary ventilation is commonly referred to as breathing. PFT’s help classify lung disorders into 2 categories: Obstructive or Restrictive. The primary function of the pulmonary system is the exchange of gases between the environmental air and the blood.

The prime function of the respiratory system is to ensure that there is effective gas exchange between air and blood. The pulmonary system consists of upper and lower airways, the chest wall, and pulmonary circulation. air moves into lungs when pressure inside lungs is less than atmospheric pressure, air moves out of lungs when pressure inside lungs is greater than atmospheric pressure Pulmonary ventilation, commonly known as ‘breathing’ is the process of moving air into and out of the lungs. • As air moves into and out of the lungs, it travels from regions of high air pressure to regions of low air pressure Page 2. Select the correct statement about the physical factors influencing pulmonary ventilation. Body position directly affects ventilation and perfusion matching and arterial oxygen levels. Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function.

Describe surfactant and its role in alveolar fluid surface tension. It is the process of air flowing into the lungs during inspiration ( inhalation) and out of the lungs during expiration ( exhalation ). Obstructive disorders (i.e. 104. Anatomy of the lungs Air enters the respiratory system through the mouth and the nasal cavity, passing through the pharynx then larynx (where sounds are produced for speech) and finally the trachea which enters the chest cavity. • To identify the muscles used during ventilation. What is the preferred way of breathing? The replacement of stale or noxious air with fresh air. Learning Objectives. The function of the pulmonary arteries is to carry blood to the lungs.

Pulmonary circulation definition is - the passage of blood from the right side of the heart through arteries to the lungs where it picks up oxygen and is returned to the left side of the heart by veins. Successful lung-protective ventilation in patients with acute lung injury and renal failure may require modification of hemodialysis in order to combat severe acidemia. C) Surfactant helps increase alveolar surface tension. Cough . the process by which air moves in and out of lungs. What happens to air through the nasal passageway? The surface tension of alveolar fluid is regulated by pulmonary surfactant, allowing efficient respiration. Respiratory capacity is the combination of two or more selected volumes, which further describes the amount of air in the lungs during a given time. 1).
