    Spirometer: To measure the patients lung capacity spirometer is used,  where a patient has to blow all the air from their lungs, from the patients blowing ability, their injury or illness severity can be predicted.

    Blood gas analyzer: Normal human being contains around 95 to 100 percent of oxygen, blood gas analyzer checks the amount of oxygen from the blood specimen, anything below 100 percent is considered as a complication.

    Volumetric exerciser: To increase the lung efficiency and to bring back the normal rhythm of breathing in ill patient, volumetric exerciser is used.

    Inhaler and Nebulizer: Patient having asthma attack and other breathing problems inhalers and nebulizer are used to administer the medication.
