Breathing Exercise Device Incentive Spirometer Coach 2 2500 [Item Number] 22-2500 For those with a vital capacity of up to 2500mL This breathing exercise device is used to improve ventilation by stimulating the lungs through displaying the inhaled volume and training to sustain deep breaths. Purchased in November 2022 at a hospital for 3850 yen (tax included). Used only a few times. Disinfected and stored. I will also disinfect it as much as possible before shipping. A copy of the instruction manual will be included. Please understand. Although it is in good condition, it has been stored at home, so I am looking forward to purchases from those who understand. #Smiths Medical Japan Co., Ltd. #Breathing Exercise Device #Spirometer #Coach 2 #Incentive #Breathing Training #Vital Capacity
