Personalise inspiratory and expiratory time to ease work of breathing | ResMed

Rise time and fall time

Customising the time required to reach IPAP and EPAP.


What’s the problem?

When the amount of time your patient requires for inhalation and exhalation is out of sync with their needs, it can cause discomfort and compromise the quality of gas exchange.

What do Rise time and Fall time do?

Rise Time and Fall time* can improve your patient’s work of breathing, comfort and synchrony by enabling you to personalise the amount of time that they have to complete inspiration and exhalation.


How do they work?

  1. Inspiratory and expiratory pressure can be adjusted to reflect your patient’s ventilatory requirements, disease type and physical condition. Rise Time is the time it takes for inspiratory pressure to reach IPAP. Fall Time* is the time it takes for expiratory pressure to reach EPAP. The greater the rise time or fall time value, the longer it takes for pressure to rise or fall to the prescribed level of IPAP (rise time) or EPAP (fall time).
  2. Patients with neuromuscular diseases may prefer a longer rise time whereas patients with high ventilatory demand, such as those with COPD, may prefer a shorter rise time and longer fall time.
  3. Rise Time and TiControl are designed to work in harmony so your patient can benefit from a comfortable inspiratory time as well as sufficient time to complete inspiration.
