Effect of Breathing Exercise on Intradialytic Hypotension in Hemodialysis Patients
14 de agosto de 2026 actualizado por: Yasemin Çelik
The Effect of Breathing Exercise on Intradialytic Hypotension and the Evaluation of Risk Factors in Hemodialysis Patients: A Randomized Controlled Study
Intradialytic hypotension is a common complication of hemodialysis that may adversely affect patient safety and treatment tolerance.
This randomized controlled study aimed to evaluate the effect of a breathing exercise on the development of intradialytic hypotension (IDH) and hemodynamic stability in patients receiving hemodialysis and to determine the factors associated with the development of IDH.
A total of 66 eligible patients were enrolled in the study and randomly assigned to the intervention and control groups.
Six participants discontinued the study because of death, unwillingness to perform the breathing exercise, or unwillingness to continue participation.
The study was completed with 60 patients.
Patients in the intervention group performed the breathing exercise during hemodialysis sessions for four weeks and 12 sessions, while patients in the control group received routine care.
Intradialytic hypotension and hemodynamic parameters were monitored throughout the study.

Experimental: Breathing Exercise Group
Participants received routine hemodialysis care and performed the breathing exercise during hemodialysis sessions three times per week for four weeks, for a total of 12 sessions.
|
Participants were taught the breathing exercise face-to-face by the researcher.
Each breathing cycle consisted of four consecutive stages: inhalation through the nose for 4 seconds using the diaphragm, holding the breath for 4 seconds, slow exhalation for 4 seconds, and holding the breath after exhalation for 4 seconds.
Each cycle lasted 16 seconds.
The exercise was performed between the 60th and 90th minutes of the hemodialysis session, after needle insertion and early ultrafiltration procedures had been completed.
During each session, participants performed two 10-minute exercise periods separated by a 5-minute rest.
The intervention was administered three times per week for four weeks, for a total of 12 sessions.
The exercise was discontinued if dizziness, dyspnea, or symptomatic hypotension developed.

|
Sin intervención: Control Group
Participants continued to receive routine hemodialysis care without performing the breathing exercise.
They had contact with the researcher at the same frequency as the intervention group.

Periodo de tiempo |
|---|---|---|
|
Occurrence of Intradialytic Hypotension
Periodo de tiempo: During each hemodialysis session over 4 weeks (12 sessions)
|
Intradialytic hypotension was assessed during each hemodialysis session.
It was defined as a decrease of at least 20 mmHg in systolic blood pressure or at least 10 mmHg in mean arterial pressure, accompanied by symptoms such as dizziness, nausea, or muscle cramps.
The occurrence of intradialytic hypotension was recorded as yes or no for each of the 12 sessions.

Periodo de tiempo |

|
Change in Systolic Blood Pressure
Periodo de tiempo: During each hemodialysis session over 4 weeks (12 sessions)
|
Systolic blood pressure was measured in mmHg before and after the breathing exercise in the intervention group and at corresponding time points in the control group during each hemodialysis session.
|
During each hemodialysis session over 4 weeks (12 sessions)
|
|
Change in Diastolic Blood Pressure
Periodo de tiempo: During each hemodialysis session over 4 weeks (12 sessions)
|
Diastolic blood pressure was measured in mmHg before and after the breathing exercise in the intervention group and at corresponding time points in the control group during each hemodialysis session.
|
During each hemodialysis session over 4 weeks (12 sessions)
|
|
Change in Mean Arterial Pressure
Periodo de tiempo: During each hemodialysis session over 4 weeks (12 sessions)
|
Mean arterial pressure was calculated in mmHg using the formula: (systolic blood pressure + 2 x diastolic blood pressure) / 3, based on measurements obtained before and after the breathing exercise in the intervention group and at corresponding time points in the control group.
|
During each hemodialysis session over 4 weeks (12 sessions)
|
|
Change in Heart Rate
Periodo de tiempo: During each hemodialysis session over 4 weeks (12 sessions)
|
Heart rate was measured in beats per minute before and after the breathing exercise in the intervention group and at corresponding time points in the control group during each hemodialysis session
|
During each hemodialysis session over 4 weeks (12 sessions)
|
|
Change in Peripheral Oxygen Saturation
Periodo de tiempo: During each hemodialysis session over 4 weeks (12 sessions)
|
Peripheral oxygen saturation was measured as a percentage using pulse oximetry before and after the breathing exercise in the intervention group and at corresponding time points in the control group during each hemodialysis session.
|
During each hemodialysis session over 4 weeks (12 sessions)
