 She has chronic lung disease, is on ventilator, but doing sprints, has been doing very well, is up to 4-1/2 hours sprints twice daily and may go up 15 minutes every three days or so; which she has been tolerating fairly well as long as they kind of get her distracted towards the end, otherwise, she does get sort of tachypneic.
