2. Incentive spirometer - Wikipedia

   en.wikipedia.org/wiki/Incentive_spirometer

   An incentive spirometer is a handheld medical device used to help patients improve the functioning of their lungs. By training patients to take slow and deep breaths, this simplified spirometer facilitates lung expansion and strengthening. Patients inhale through a mouthpiece, which causes a piston inside the device to rise.

3. Artificial ventilation - Wikipedia

   en.wikipedia.org/wiki/Artificial_ventilation

   The process of forcing air into and out of the lungs is known as ventilation. The process by which oxygen is taken in by the bloodstream is called oxygenation. Lung compliance is the capacity of the lungs to contract and expand. The obstruction of airflow via the respiratory tract is known as airway resistance.

4. Negative pressure ventilator - Wikipedia

   en.wikipedia.org/wiki/Negative_pressure_ventilator

   NPVs do not work well if patient's lung compliance is decreased, or their lung resistance is increased. [2] They result in a greater vulnerability of the airway to aspiration, such as inhalation of vomit or swallowed liquids, than with intermittent positive pressure ventilation. [1] They exacerbate obstructive sleep apnea. The device is not ...

5. Ventilator - Wikipedia

   en.wikipedia.org/wiki/Ventilator

   A ventilator is a type of breathing apparatus, a class of medical technology that provides mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing

6. Mechanical ventilation - Wikipedia

   en.wikipedia.org/wiki/Mechanical_ventilation

   Mechanical ventilation helps move air into and out of the lungs, with the main goal of helping the delivery of oxygen and removal of carbon dioxide. Mechanical ventilation is used for many reasons, including to protect the airway due to mechanical or neurologic cause, to ensure adequate oxygenation, or to remove excess carbon dioxide from the ...

7. Continuous positive airway pressure - Wikipedia

   en.wikipedia.org/wiki/Continuous_positive_airway...

   Both modalities stent open the alveoli in the lungs and thus recruit more of the lung surface area for ventilation. However, while PEEP refers to devices that impose positive pressure only at the end of the exhalation, CPAP devices apply continuous positive airway pressure throughout the breathing cycle. Thus, the ventilator does not cycle ...
