1 Μαΐ 2013 · The P co 2 is controlled primarily by alveolar minute ventilation, which is equal to the product of the respiratory rate and effective (alveolar) tidal volume (TV). Consequently, causes of severe hypoventilation are diseases that impair the ability of patients to maintain an adequate respiratory rate and/or TV.
To evaluate a novel physiological approach for setting the tidal volume in mechanical ventilation according to inspiratory capacity, and to determine if it results in an appropriate mechanical and gas exchange measurements in healthy and critically ill dogs.
Minute volume = the volume of air inhaled or exhaled in one minute. FORMULA FOR WORKING OUT FLOW RATE. The animal’s tidal volume must be calculated fi rst: Tidal volume = 10–15 ml/kg Cats/small dogs = 15 ml/kg Medium/large dogs = 10 ml/kg. To fi nd out the minute volume, multiply the tidal volume by the respiration rate per minute.
10 Ιουν 2016 · To evaluate three routinely used tidal volumes (VT; 10, 12 and 15 mL kg−1) for controlled mechanical ventilation (CMV) in lung-healthy anaesthetized dogs by assessing alveolar ventilation (VTalv) and dead space (DS).
Modes of Ventilation. Pressure-controlled ventilation (PC) Gas is delivered to a chosen airway pressure, regardless of the tidal volume. Appropriate for animals with lung disease. Volume-controlled ventilation (VC) A pre-determined tidal volume is given regardless of the airway pressure generated.
The recommended Vt for the MV of healthy dogs ranges from 10 to 20 mL/kg [2, 14], even though the use of a high Vt level of 20 mL/kg in patients could lead to overdistention and lung injury, making these recommendations questionable.
