Calculate the minute ventilation for the 5mm tube and then for the 3 mm tube. What effect does decreasing tube radius have on resistance and minute ventilation?

Respuesta :

Calculating minute ventilation, this formula should be used:

  • Minute ventilation = tidal volume x respiratory rate (normal is 4-6 L/min) Tidal volume = alveolar space + dead space.

What is minute ventilation?

Minute ventilation is the tidal volume times the respiratory rate, usually, 500 mL × 12 breaths/min = 6000 mL/min.

Therefore, the 5mm tube will be calculated as:

500 x 15= 7,500 mL/min.

And the 3mm tube will be calculated as:

65 x 15= 975mL/min

The effect decreasing the tube radius will have on increased resistance and minute ventilation is that there will be a decrease in the tube minute ventilation.
