Incentive spirometer

Incentive spirometer is indicated for patients who have had any surgery that might jeopardize respiratory function, particularly surgery to the lungs,{{cite web | url=http://my.clevelandclinic.org/services/Surgery/hic_How_to_Use_an_Incentive_Spirometer.aspx | title=How to use an incentive spirometer | work=The Cleveland Clinic Foundation | accessdate=2013-11-03}} but also to patients recovering from cardiac or other surgery involving extended time under anesthesia and prolonged in-bed recovery. Under general anesthesia and inactivity, a patient's breathing may slow, causing air sacs in their lungs to not fully inflate. Atelectasis can develop and, if unmanaged, lead to pneumonia and postoperative fever. Pneumonia is a major lung complication associated with increased morbidity and mortality, length of hospital stay, and likelihood of hospital readmissions.{{cite journal |last1=Chughtai |first1=Morad |last2=Gwam |first2=Chukwuweike U. |last3=Mohamed |first3=Nequesha |last4=Khlopas |first4=Anton |last5=Newman |first5=Jared M. |last6=Khan |first6=Rafay |last7=Nadhim |first7=Ali |last8=Shaffiy |first8=Shervin |last9=Mont |first9=Michael A. |title=The Epidemiology and Risk Factors for Postoperative Pneumonia |journal=Journal of Clinical Medicine Research |date=2017 |volume=9 |issue=6 |pages=466–475 |doi=10.14740/jocmr3002w |pmid=28496546 |pmc=5412519 }} In conjunction with breathing exercises and early mobility, incentive spirometry use is therefore beneficial for patients recovering from pneumonia or rib damage to help minimize the chance of fluid build-up in the lungs. Because of its role in pulmonary rehabilitation and inspiratory muscle training, this device may theoretically benefit patients with COVID-19.{{cite journal |last1=Seyller |first1=Hannah |last2=Gottlieb |first2=Michael |last3=Colla |first3=Joseph |title=A breath of fresh air: The role of incentive spirometry in the treatment of COVID-19 |journal=The American Journal of Emergency Medicine |date=October 2021 |volume=48 |pages=369 |doi=10.1016/j.ajem.2021.01.084 |pmid=33558097 |pmc=8500986 }} It may be used as well by wind instrument players who want to improve their air flow.{{cn|date=July 2022}}

While there are no absolute contraindications for spirometry use, inspiratory muscle training can worsen some existing medical conditions, including the following:

{{div col|colwidth=20em|small=yes}}

• Recent or current respiratory tract infection
• Hemoptysis of unknown origin
• Pneumothorax
• Emphysema, due to increased barotrauma{{cite journal |last1=Kenny |first1=Jon-Emile S |last2=Kuschner |first2=Ware G |title=Pneumothorax Caused by Aggressive Use of an Incentive Spirometer in a Patient With Emphysema |journal=Respiratory Care |date=July 2013 |volume=58 |issue=7 |pages=e77–e79 |doi=10.4187/respcare.02130 |pmid=23232741 |s2cid=74429 |doi-access=free }}
• Thoracic, abdominal, or cerebral aneurysms

Patient starts in a seated upright position. Patient exhales completely before using device. The patient then places the mouthpiece into their mouth and seals their lips tightly around it. The patient breathes in from the device as slowly and as deeply as possible, then holds that breath in for 2–6 seconds. This provides back pressure that pops open alveoli. It has the same effect as that which occurs during yawning. An indicator piston driven by the patient's breathing provides a gauge of how well the patient's lungs (or lung if singular) are functioning, by indicating sustained inhalation vacuum. While the patient is holding their breath, the indicator piston will slowly return to the bottom of the column. Patient then removes the mouthpiece from their mouth and exhales normally. Coughing can be expected to clear the airway and lungs of mucus. Patients are encouraged to rest if they begin feeling dizzy.

Generally, patients are encouraged to do many repetitions a day while measuring progress by way of advancing the movable gauge along the central column of the device as they improve.{{cn|date=July 2022}}

Traditional incentive spirometers can be more challenging for children due to compliance and submaximal effort.{{cite journal |last1=Gupta |first1=Anish |last2=Mishra |first2=Priyanka |last3=Gupta |first3=Bhavna |last4=Kakkar |first4=Kamna |title=A kid-friendly approach to Incentive Spirometry |journal=Annals of Cardiac Anaesthesia |date=2021 |volume=24 |issue=2 |pages=238–240 |doi=10.4103/aca.ACA_188_19 |pmid=33884984 |pmc=8253039 |doi-access=free }} Age-appropriate devices including whistles, pinwheels, and bubble wands should be considered.{{cite journal |last1=Schivinski |first1=Camila Isabel Santos |last2=Manna |first2=Bruna Cardoso |last3=Belém |first3=Fabíula Joanita da Mata |last4=Castilho |first4=Tayná |title=Therapeutic blowing toys: does the overlap of ventilatory stimuli alter the respiratory mechanics of healthy schoolchildren? |journal=Revista Paulista de Pediatria |date=2020 |volume=38 |pages=e2018259 |doi=10.1590/1984-0462/2020/38/2018259 |pmid=32159645 |pmc=7063596 }} These toys and activities reinforce proper breathing mechanics by stimulating deep inhalation and prolonged exhalation.{{cn|date=July 2022}}
