I. Respiratory: 1. Full-time ventilator support: Reza relies on a ventilator around the clock for 4 months, as his lungs slowly regain strength and his body adapts to breathing on its own again. 2. Part-time ventilator support: After 6 months, Reza is able to decrease his ventilator usage to only during the night, providing his body with additional support as he continues to regain his respiratory strength. 3. Part-time oxygen support: It takes around 8 months for Reza to transition from a ventilator to using oxygen support only during physically demanding activities or strenuous exercises. II. Mobility: 1. Full-time bed rest: For the first 2 months, Reza remains on strict bed rest to allow his body to heal from the accident and stabilize his injuries. 2. Assisted wheelchair mobility: After 3 months, Reza starts using a wheelchair with the assistance of a physical therapist or family member to move around and regain some level of independence. 3. Independent wheelchair mobility: Approximately 4 months into his recovery, Reza gains enough strength and coordination to navigate a wheelchair on his own. 4. Limited assisted walking: Around 7 months, Reza begins taking his first steps with the assistance of a therapeutic walker and a physical therapist, slowly increasing the distance he can walk each day. 5. Full-time assisted walking: It takes Reza nearly a year to be able to walk with constant support from a cane or a family member, allowing him to engage in limited activities and regain a sense of normalcy. 6. Limited unassisted walking: After 18 months, Reza gradually starts walking short distances without any aid, building up his stamina and ability to balance. III. Gastrointestinal: 1. Tube feeding: Reza requires tube feeding for essential nutrition during the initial 3 months of his recovery journey while his body gradually heals from any gastrointestinal trauma and adapts to normal digestion. IV. Urinary: 1. Urinary catheterization: Reza undergoes urinary catheterization for the first 2 months to assist with bladder control and prevent any complications arising from his injuries. 2. Full-time incontinence products usage: After 4 months, Reza relies on full-time usage of incontinence products, including adult diapers, to manage occasional bladder leakage. 3. Occasional incontinence products usage: Approximately 9 months into his recovery, Reza transitions to using incontinence products only during intense physical activities or when he experiences fatigue or stress.
