Dead Space Ventilation
Monitoring alveolar dead space during a surgical operation is a sensitive and important tool in monitoring airway.
Dead space ventilation. Some apparatus dead space may actually reduce total dead space as an ett bypasses the majority of anatomical dead space of the patient nasopharynx. Physiological dead space refers to a condition that results in reduced perfusion to well ventilated alveoli. Factors that increase dead space.
Dead space from equipment such as tubes ventilator circuitry. Dead space ventilation involves that component of the respiratory gases that does not participate in gas exchange. With the subsequent development of a simple.
It is determined by subtracting the dead space volume from the tidal volume and multiplying the result by the respiratory rate. During strenuous exercise co 2 will rise. It is a function of the size of the tidal volume the rate of ventilation and the amount of dead space present in the respiratory system.
This is something that should not occur in healthy people like in the conditions described above. The current calculation of physiological dead space utilising measurements of arterial co 2 tension p aco 2 and mixed expired co 2 tension p eco 2 was initially thought to include an anatomical dead space representing the fraction of ventilation advancing no further than the conducting airways and an alveolar dead space representing the fraction of ventilation delivered to alveolar surfaces receiving no pulmonary artery perfusion. Alveolar dead space poorly ventilated alveoli do not generally empty at the same rate as healthy alveoli.
The movement of air into and out of the alveoli.
