Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients who are planned for abdominal surgery under elective conditions and who meet the inclusion criteria will be divided into 2 groups after routine preoperative preparations. The 1st group will start at least 5 days before the preoperative period and until the preoperative period, a minimum of 5 minutes of effective triflo exercise will be performed 4 times a day under the supervision of a nurse, and the 2nd group (control group) will not be exercised except for routine preoperative preparation. Age, existing chronic diseases, body mass index, haemoglobin levels, smoking status, presence or absence of lung disease, SpO2 values before and at the end of respiratory exercise (in the preoperative respiratory exercise group) will be recorded. All patients will be monitored with ECG, SpO2, non invasive blood pressure, Masimo. After the patients are taken to the operating table, they will be preoxygenated with oxygen at FiO2 100% at 10 L\\min in supine position, with the anaesthesia mask placed on the patient's face so that there is no leakage. Patients will be preoxygenated until ETO2 concentration reaches 85%. When preoxygenation is started, the timer will be started and the time to reach ORI:0.55 and the time to reach ETO2 85% will be measured and recorded with a timer. Preoxygenation time will be limited to a maximum of 5 minutes and patients who do not reach ETO2 concentration 85% or ORI:0.55 within 5 minutes will be noted.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control (C)

Patients in the control group who will undergo abdominal surgery will not be given any breathing exercises other than routine preoperative preparation. After appropriate anesthesia preparation, preoxygenation will begin.

No interventions assigned to this group

Triflo (T)

The patient group who receives breathing exercises will be given effective triflo exercise under the supervision of a nurse, starting with hospitalization at least 5 days before the operation and until the pre-operative period. Triflo working time will be planned to be minimum 5 minutes 4 times a day. Breathing exercise will be performed with both inhalation and exhalation. After appropriate anesthesia preparation, preoxygenation will begin.
