The steps of rib fixation are as follows: 1. Ask the patient to raise both hands above the head and place the concave side of the rib fixation belt against the armpit and the front side against the chest wall. 2. Adjust the rib fixation belt so that the patient does not have difficulty breathing and is not too loose, and then stick the Velcro fastener in place, paying attention to the patient’s breathing during the fixation process. 3. 4.After fixation, ask the patient to breathe to see if there is respiratory distress, and ask the patient if he feels too tight or too loose, if too tight may affect respiration and blood circulation, too loose will not achieve the role of fixation. 5.The rib fixation belt is worn when getting out of bed, and can be removed when resting in bed or sleeping.
