I. Respiratory: 1. Full-time ventilator support: The doctors estimate that Reza will require full-time ventilator support for approximately three months. During this time, he is hooked up to a complex respiratory device that helps him breathe and recover from the injuries sustained in the accident. 2. Part-time ventilator support: After three months, Reza gradually progresses to only requiring part-time ventilator support. The doctors anticipate that he will need this support for another two to three months before he can breathe comfortably on his own. 3. Part-time oxygen support: Following the reduction in ventilator support, Reza transitions to part-time oxygen support. This stage lasts for around one month as his lungs regain strength and become accustomed to breathing independently once again. II. Mobility: 1. Full-time bed rest: Due to the severity of his injuries, Reza is confined to full-time bed rest for the first four months. This period allows his body to heal and rebuild strength while minimizing the risk of further injury. 2. Wheelchair mobility: After four months, Reza slowly progresses to using a wheelchair to regain mobility. This stage lasts approximately six months, during which he undergoes physical therapy and gradually learns to maneuver the wheelchair independently. 3. Assisted walking: Around ten months after the accident, Reza begins assisted walking. Supported by crutches or a walking frame, he gradually relearns the mechanics of walking, building up his strength and balance. This phase lasts for about one year until he can confidently walk unaided. III. Gastrointestinal: 1. Tube feeding: During the initial stages of his recovery, Reza requires tube feeding due to difficulties with swallowing caused by his injuries. The doctors estimate that this stage may last for six to eight weeks until his ability to eat and swallow safely is restored. IV. Urinary: 1. Catheterization: In the initial weeks after the accident, Reza requires catheterization to assist with urinary function. It is expected that this stage will last for three to four months as his body heals and regains control over bladder functions. 2. Absorbent products usage: Following the removal of the catheter, Reza may rely on absorbent products for an additional month or two. This allows for any residual issues with bladder control to be managed seamlessly as he continues to recover.
