You are looking for required_if.

So, you could have the following rules in your Form Request or your Validator.

return [
    'systolic_blood_pressure_high' => 'nullable|numeric|min:1|required_if:has_systolic_bp,on',
    'systolic_blood_pressure_low'  => 'nullable|numeric|min:1|required_if:has_systolic_bp,on',
];

Assuming you have a checkbox with name has_systolic_bp and it is checked, the fields systolic_blood_pressure_high and systolic_blood_pressure_low will be required.

You also need to mark them as nullable as by default Laravel will consider them as invalid because of the TrimStrings and ConvertEmptyStringsToNull middlewares.
