$I:Time = 1.0$ seconds

If the respiratory rate is 12 breaths per minute and the I:E ratio is 1:4, what is the total cycle time (TCT) in seconds?

$TCT = 5$ seconds

Study Notes

ICU Equipment and Ventilators

Mechanical ventilators are commonly used to assist breathing in an ICU.

Pain Management in the ICU

Analgesics are used in the ICU to manage pain and promote comfort.

Cardiac Monitoring in the ICU

Cardiac monitors are used in the ICU to track and display a patient's heart rate and rhythm.

Ventilator Calculations

The total cycle time (TCT) can be calculated from the respiratory rate (f) using the formula: TCT = 60/f.
The default inspiratory time (I:Time) for the Pediatric ReVel ventilator is 0.5 seconds.

Ventilator Settings and Calculations

A measured I:E ratio of 1:3.2 indicates that the inspiratory time is 1 unit and the expiratory time is 3.2 units.
If the ventilator is set with a tidal volume (Vt) of 500 mL and a flow rate of 0.5 L/s, the inspiratory time (I:Time) can be calculated as: I:Time = Vt / Flow rate = 500 mL / 0.5 L/s = 1 second.
If the respiratory rate is 12 breaths per minute and the I:E ratio is 1:4, the total cycle time (TCT) can be calculated as: TCT = 60/f = 60/12 = 5 seconds.
