Chronic cardiac failure
Conditions
Interventions
Intervention group:1. Preoperative Intervention (5 times per week for 2 weeks)
(1) Rehabilitation Education: Abdominal breathing and enhanced limb mobility
(2) Cycling Training: Target heart
3 exercises × 10 repetitions × 3 sets, 5–10 min, RPE 11–13
(4) Respiratory Function Training: 30% MIP, 30% MEP
if patient RPE < 5, increase load by 5% in the next session
5–10 min per session, RPE 11–13
2. Postoperative Intervention (Start 1 week after surgery, 5 times per week for 2 weeks)
(1) Respiratory Function Training: Same as preoperative intervention
one set morning and evening, 10 repetitions per set
3) Indoor walking: 3 min per session, 2 sessions per day
4) Outdoor walking: 5 min per session, 2 sessions per day
5) Cyclin
Control group:1. Preoperative Intervention (5 times per week for 2 weeks)
Rehabilitation education and routine nursing: Abdominal breathing and enhanced limb mobility
2. Postoperative Interven
