چکیده
sacs,' which are main cavities of which the walls are constituted by alveoli or air-cells. By far the greater number of the lung alveoli belong to the air-sac system, but a very appreciable number belong to the atria, and the latter act partly as air-passages to the air-sacs, and partly perform the same respiratory functions as the air-sacs themselves. The walls of the atria have the same general structure as those of the

A Model of the Respiratory System in the Newborn Infant
A dynamic mathematical model is presented which successfully simulates the respiratory control system of the newborn infant in different physiological conditions. The primary objective in constructing this model has been to provide a simulation aid in the investigation of maturation of the respiratory system, and the respiratory disorders during the newborn period, without the need for invasive...
متن کاملLost Space Renewal; a Reborn of an Urban Water Body
Due to rapid growth of urbanization and economic demand, we are continuously losing our fields,our free lands, open sky, ponds, lakes; actually our breathing spaces. Sometimes for zoning policies, migration ortransferal of a particular business or activity, a place like waterfronts, body of water, military or industrial sites can lostits importance, kept vacant and become a dead place. These ar...
متن کاملTime and volume dependence of dead space in healthy and surfactant-depleted rat lungs during spontaneous breathing and mechanical ventilation.
Volumetric capnography is a standard method to determine pulmonary dead space. Hereby, measured carbon dioxide (CO2) in exhaled gas volume is analyzed using the single-breath diagram for CO2. Unfortunately, most existing CO2 sensors do not work with the low tidal volumes found in small animals. Therefore, in this study, we developed a new mainstream capnograph designed for the utilization in sm...
متن کاملThe effects of passive humidifier dead space on respiratory variables in paralyzed and spontaneously breathing patients.
BACKGROUND Passive humidifiers have gained acceptance in the intensive care unit because of their low cost, simple operation, and elimination of condensate from the breathing circuit. However, the additional dead space of these devices may adversely affect respiratory function in certain patients. This study evaluates the effects of passive humidifier dead space on respiratory function. METHO...
متن کاملThe principle of upper airway unidirectional flow facilitates breathing in humans.
Upper airway unidirectional breathing, nose in and mouth out, is used by panting dogs to facilitate heat removal via water evaporation from the respiratory system. Why some humans instinctively employ the same breathing pattern during respiratory distress is still open to question. We hypothesized that 1) humans unconsciously perform unidirectional breathing because it improves breathing effici...
متن کاملNoninvasive measurement of mean alveolar carbon dioxide tension and Bohr's dead space during tidal breathing.
The lack of methodology for measuring the alveolar carbon dioxide tension (PA,CO2) has forced investigators to make several assumptions, such as that PA,CO2 is equal to end-tidal (PET,CO2) and arterial CO2 tension (Pa,CO2). The present study measured the mean PA,CO2 and Bohr's dead space ratio (Bohr's dead space/tidal volume (VD,Bohr/VT)) during tidal breathing. The method used is a new, simple...
