Can all patients hold their breath during radiation therapy?
Not all patients can hold their breath consistently for the required time (20-30 seconds per radiation field.) Technically, ensuring an accurate set up is more challenging and requires ‘coaching’ the patient on how to do the breathing technique.
How long should you hold your breath during breast cancer treatment?
This technique is called “deep inspiration breath holding,” and requires that you are able to hold your breath for between 20-30 seconds during treatments. This is particularly important for left-sided breast cancers.
How long do you need to stay in the hospital for radiation?
You may need to stay in the hospital for 1 or 2 days, and may need to take special precautions at home. To protect others from radiation, the drugs are kept in special containers that hold the radiation inside, and you’ll be treated in a shielded room that also keeps the radiation inside.
What is the role of deep inspiration breath hold in radiation therapy?
Over the past several years, advances in radiation delivery techniques have reduced cardiac morbidity due to treatment. Deep inspiration breath hold (DIBH) is a technique that takes advantage of a more favorable position of the heart during inspiration to minimize heart doses over a course of radiation therapy.
How long do you have to hold your breath during radiation?
The radiation therapy team will provide you with coaching before starting your treatment. During deep inspiration breath hold you will be required to hold your breath for up to 20 seconds. The radiation beam will only turn on when you have taken a deep breath in.

How many times do you have to hold your breath during breast radiation?
Because breast cancer patients undergo daily radiation treatments for several weeks and two beams of radiation are administered at each session, they must be able to hold their breath twice for 20 seconds during each treatment.
Why do you have to hold your breath during radiation for breast cancer?
When you hold your breath, it inflates your lungs and pushes your heart away from your chest wall and the treatment area. This helps minimize any potential radiation damage to the heart.
What can you not do during radiation treatment?
Avoid raw vegetables and fruits, and other hard, dry foods such as chips or pretzels. It's also best to avoid salty, spicy or acidic foods if you are experiencing these symptoms. Your care team can recommend nutrient-based oral care solutions if you are experiencing mucositis or mouth sores caused by cancer treatment.
How long does it take to recover from radiation therapy?
Most side effects generally go away within a few weeks to 2 months of finishing treatment. But some side effects may continue after treatment is over because it takes time for healthy cells to recover from the effects of radiation therapy. Late side effects can happen months or years after treatment.
Why do I have to hold my breath during mammogram?
The technician may also ask you to hold your breath for a few seconds to better get a still shot. Quality images are achieved by using a plate to compress each breast. Usually, a screening mammogram requires two pictures of each breast, but some women will require additional pictures.
Why do you get tired during radiation?
Most people start to feel tired after a few weeks of radiation therapy. This happens because radiation treatments destroy some healthy cells as well as the cancer cells. Fatigue usually gets worse as treatment goes on. Stress from being sick and daily trips for treatment can make fatigue worse.
How long can you hold your breath?
The longest instance of someone holding their breath without inhaling pure oxygen beforehand is 11 minutes and 34 seconds. However, most people can only safely hold their breath for 1 to 2 minutes. The amount of time you can comfortably and safely hold your breath depends on your specific body and genetics.
How do you breathe in radiation?
Deep inspiration breath hold (DIBH) is a radiation therapy technique where patients take a deep breath during treatment, and hold this breath while the radiation is delivered. By taking a deep breath in, your lungs fill with air and your heart will move away from your chest.
Can you work while getting radiation for breast cancer?
Radiation. You should be able to work while receiving radiation treatments. While your radiation schedule will usually be 5 days a week for 5 to 7 weeks, the appointments are generally short. Treatment centers work efficiently so that the process only takes 15 to 30 minutes.
Can I take vitamins during radiation?
Taking small amounts of antioxidants does not affect your radiation treatment. Small amounts of antioxidants like those found in food and some multivitamins are safe.
When is a deep inspiration breath hold used in breast cancer treatment?
The type of treatment will depend on the size and location of the tumor in the breast, the results of lab tests done on the cancer cells, and the stage , or extent, of the disease.
How does deep inspiration breath hold protect the heart?
One way to protect your heart while you are receiving radiation therapy is to hold your breath via DIBH. The radiation is then delivered to your breast while you are holding your breath deeply for 20 seconds. This will provide protection for your heart.
What is deep inspiration breath hold?
Deep Inspiration Breath Hold in Breast Cancer Treatment. When you take a deep breath and hold it, your diaphragm (a large, dome-shaped muscle located at the base of the lungs) pulls your heart away from your chest. This is known as a deep inspiration breath hold (DIBH). This article describes how DIBH protects the heart during radiation therapy ...
How long does radiation therapy take for breast cancer?
Radiation therapy is usually given after a lumpectomy (partial mastectomy) for one to six weeks to treat the remaining breast tissue.
How to prepare for radiation treatment?
You can also help prepare for DIBH during radiation treatment by practicing taking deep breaths and holding them at home, before your treatments . Studies have shown that practicing at home every day can help you improve your skills in DIBH. If you want to learn more about DIBH, please ask your caregivers.
Why is the left breast closer to the heart?
This is because the left breast is closer to the heart, which means it may be in the radiation field. (The lung may also be in the radiation field.) If the heart receives radiation during breast cancer treatment, women may be at greater risk for coronary heart disease.
What is the name of the muscle that pulls your heart away from your chest?
When you take a deep breath and hold it, your diaphragm (a large, dome-shaped muscle located at the base of the lungs) pulls your heart away from your chest. This is known as a deep inspiration breath hold (DIBH). Cleveland Clinic is a non-profit academic medical center.

If playback doesn't begin shortly, try restarting your device.
What is proton therapy for breast cancer?
Proton therapy is another breast cancer radiation modality used to spare heart radiation exposure, taking advantage of the dosimetric properties of protons to reduce cardiac doses. Recent series have shown remarkably low cardiac doses with proton therapy (101). Comparisons of protons at free-breathing versus photons with DIBH have shown that both techniques yield remarkably low heart doses, although proton plans appear to deliver lower mean heart dose and lower dose to the LAD (102). Whether the very small differences in mean heart dose between protons and photons at DIBH will be clinically relevant is in question. Combination series of protons delivered at DIBH have appeared to show no significant improvements over protons at free breathing (103). Notably, the breast contour can evolve significant during radiotherapy due to reabsorption of the seroma or breast edema of shrinkage (104). Proton dosimetry is somewhat less robust to changes in breast size that can occur over the course of treatment as compared to photon plans. As a result, imaging during the RT course and replanning in the event of a contour change, could be considered. Whether the very small differences in mean heart dose between photons using DIBH and protons, and whether the physical and biological uncertainties associated with protons, will be clinically relevant is in question. These questions may be answered by the currently accruing PCORI RADCOMP trial (105). This trial aims to enroll 1,716 patients receiving radiotherapy to the breast or CW in conjunction with the internal mammary nodes and randomize them to radiotherapy with either protons or photons. The primary endpoints of this trial are cardiac events and cancer control events.
How to do DIBH?
For DIBH treatment, at least two CT scans corresponding to free breathing and DIBH have to be acquired during simulation. Patients are coached to breathe through their nose instead of mouth. The patient contours on the two CT scans will be used to match the corresponding daily patient surfaces from the optical tracking system during treatment setup for assuring that patients reach the same level of breathhold as that during simulation. When treating the left-sided breast patients with nodal involvement using DIBH delivery, both nodal and breast fields should be delivered at breathhold due to the matchline between nodal and breast fields. Feathering of the matchline may not be necessary during treatment because a 3 mm threshold of DIBH position uncertainty is usually applied in the surface tracking systems. The number of field-in-fields should be minimized (preferably <4 fields) for more rapid treatment delivery. This is one reason why IMRT planning is not often combined with DIBH delivery. Some types of bolus may not be tracked well by the optical tracking system. Wet towels may be used to replace the more rigid bolus during DIBH delivery (72). Alternatively, a conformal brass bolus can be used and cloth tape can be placed over the bolus to increase contrast for the optical tracking system.
What is the treatment plan for DIBH?
Much like free breathing, treatment modalities include 3D radiation therapy, IMRT, as well as arc therapy (34, 48, 50). Some studies have reported that wide tangents, when combined with DIBH, may reduce cardiac dose even further (34), and the technique has been favored by many with regard to treatment of the IMCs (84, 85). In addition, the wide tangent technique achieved superior IMC dose coverage compared to the traditional photon–electron technique (86, 87), which makes wide tangents the favorable technique in DIBH planning for IMC irradiation. However, a recent paper from Borm et al. evaluated the dosimetric impact of DIBH on the axillary lymph nodes (88). In this study, the authors demonstrated that the axillary nodes move with DIBH, and the magnitude of that movement is significantly different than the movement of the lumpectomy cavity and the breast. This can result in a reduction of incidental dose to the axilla, with the mean dose to the level 1 axilla reduced by roughly 10% (88). For patients with a positive sentinel node biopsy who forgo axillary dissection, this incidental radiation dose to axillary level 1 may contribute to the low risk of axillary recurrence risk observed in patients treated in this manner (89, 90). Consequently, if therapeutic dose to the level 1 axilla is desired, these authors recommend delineating that region as a target and designing fields appropriately to cover the target.
How to decrease heart dose?
Another technique that can be used to decrease heart dose is deep inspiration breath hold (DIBH). The technique is based upon the observation that during inspiration, the flattening of the diaphragm and expansion of the lungs pulls the heart away from the CW. During both simulation and treatment, the patient takes a deep breath and then holds it for a period of time during which radiation is administered. This allows for a decrease in radiation dose to the heart (Figures (Figures1A,B)1A,B) (26). While DIBH can be used alternatively to prone breast irradiation (27), the two techniques can and have been used in conjunction (28, 29).
What is vdibh in medical?
Alternatively, patients can undergo vDIBH, where respiratory motion is monitored, and the patient is instructed to hold his or her breath at certain points in the breathing cycle. One example of this technique is the Varian RPM (real-time position management) system (Varian Medical Systems, Palo Alto, CA, USA), where a device is placed on the patient’s chest and vertical displacement throughout the respiratory cycle provides surrogate data to create a tracing of the patient’s breathing (Figures (Figures1C,D).1C,D). With this technique, the patient is coached and must voluntarily hold their breath. The treatment beam can be gated so that treatment is stopped when the breathing signal falls outside a preset threshold. This type of gating in DIBH, in which the beam is turned off only in the event that the breath hold is out of target range, should be differentiated from standard respiratory gating, in which the patient is breathing free and the beam is repeatedly turned off during a predetermined portion of the respiratory cycle. Unlike DIBH, respiratory gating at free breathing is not usually an effective method for cardiac sparing because at no point in the standard respiratory cycle does the heart move dramatically away from the breast or chest wall. It appears that vDIBH is quite comparable to ABC DIBH on multiple levels. The UK HeartSpare study (61) compared the two techniques using a crossover study, where patients initially received treatment with one DIBH technique for one half, followed by the other technique for the other half of their therapy. The study noted similar overall treatment times, but found that vDIBH was associated with decreased time for both simulation and daily setup. Additionally, both patients and therapists endorsed greater satisfaction with the vDIBH technique (61). In fact, a study by Eldredge-Hindy et al. noted that 18% of the 112 patients enrolled in their study did not tolerate the ABC technique (62). All of these studies, along with the fact that vDIBH can be executed relatively cheaply (61, 63), question whether ABC is necessary for DIBH.
Is DIBH tolerated?
Although DIBH is well tolerated by most patients, patients should be screened and carefully selected after taking into account factors such as ability to tolerate the technique, cost, patient convenience, and potential benefit based on size, location, and type of tumor. As noted previously, patients with left-sided breast cancers appear to have increased cardiac mortality simply due to the proximity of the target to the heart, therefore, it is likely these patients that would benefit most from the DIBH technique. Based on this, many centers currently only offer DIBH to patients with left-sided disease.
Can DIBH be used for breast cancer?
Patients with right-sided breast cancers may also benefit from DIBH, largely due to decreased ipsilateral and total lung doses associated with use of DIBH in patients receiving IMC radiation (60). Additionally, DIBH has been shown to more significantly decrease the heart dose in women receiving nodal irradiation to the IMC (56), largely due to the increased heart dose associated with IMC treatment when compared to treatment of the breast and CW alone (18). While the cardiac toxicity associated with IMC irradiation is worse with left-sided disease, the risk applies to patients with both left- and right-sided disease due to proximity of the target to the heart. DIBH use in right-sided patients can also result in lowered ipsilateral lung and liver doses (80). Hence, these patients with right-sided disease and concern for lung dose, as well as patients undergoing IMC irradiation should also be considered for DIBH. Tolerability of the technique, as noted above, should also be a consideration. While the technique is well tolerated overall, DIBH treatment can take longer when compared to a standard free breathing technique, and patients should be able to lie comfortably flat on their back for the duration of treatment.
How long can you hold your breath during radiotherapy?
The technique increases oxygen levels in the lungs and removes carbon dioxide from the blood, enabling individuals to hold their breath safely for up to 6 min and for multiple times in a single session.
How long can you hold breath on a PET scan?
The technique increases oxygen levels in the lungs and removes carbon dioxide from the blood, enabling individuals to hold their breath safely for up to 6 min and for multiple times in a single session. Movement in the thorax and abdomen during an MRI or PET scan can negatively impact the diagnostic quality of the exam.

With practice over a few days, all 30 could perform single prolonged breath-holds safely for around 6 min.
Who invented the mechanical ventilator?
Parkes and Clutton-Brock invented the mechanical ventilator technique approximately 20 years ago. “It is the easiest and safest method of lowering blood carbon dioxide levels,” Parkes explains. “While voluntary hyperventilation is possible, it is too difficult for individuals to do reliably and safely.”
Is it safe to hold your breath for a long time?
The study demonstrates for the first time that multiple prolonged breath-holds are feasible and safe, according to the authors. It also shows three major new features of their prolonged breath-holding technique.
Who developed the oxygen halved oxygen approach?
Co-principal investigators Michael Parkes, Stuart Green, Qamar Ghafoor and Tom Clutton-Brock developed an approach in which individuals breathe oxygen-enriched air (60% oxygen) and halve blood carbon dioxide levels by mechanical ventilation through a face mask.
What is the role of a physicist in respiratory motion?
It is recommended that, due to the complexity of the management of respiratory motion problem and the technology used, a physicist be present at all imaging sessions in which respiratory management devices are used and also for at least the first treatment for each patient. A physicist should also be available for consultation during the treatment planning process and all treatment sessions. The physicists involved with the procedures should have appropriate understanding of the equipment, and have attended, where possible, training on the specific device(s) used.
What are the concerns of ABC?
As with DIBH, the primary concerns of ABC for individual patients involve reproducibility and duration of breath hold. Early studies indicate a difference in short- and long-term reproducibility, thus potentially indicating the need for integration of ABC with routine image-guided adjustment of setup.
What is FSB in medical terms?
Forced shallow breathing (FSB) was originally developed for stereotactic irradiation of small lung and liver lesions by Lax and Blomgren at Karolinska Hospital in Stockholm.77-79 These techniques have been shown to reduce the magnitude of intra-fractional motion.46,80-82 This technique employs a stereotactic body frame with an attached pressure plate that is pressed against the abdomen in a reproducible fashion. The applied pressure to the abdomen is administered to minimize diaphragmatic excursions, thereby reducing the volume of gases exchanged during normal respiration while still permitting limited normal respiration. Elekta Instruments, Inc. commercially produces the body frame and the pressure plate system. The accuracy of the reproducibility of both the body frame and the pressure plate has been evaluated by several groups, with the most comprehensive and careful assessment of this device being published by Negoro et al. from Kyoto University School of Medicine.83
What are the different types of respiration techniques used in radiotherapy?
The methods that have been developed to explicitly account for respiration motion in radiotherapy can be broadly separated into four major categories: respiratory gating techniques, breath-hold techniques, forced shallow breathing techniques, and respiration synchronized techniques. These methods are discussed in this section.
What are the three techniques for CT scanning?
Three techniques for CT scanning are possible that include the entire range of tumor motion for respiration (at least at the time of CT acquisition) are slow CT, inhale and exhale breath hold CT and 4D CT. These are listed in order of increasing workload. For all of these techniques it is important to understand that the breathing patterns, and hence tumor motion will change between simulation sessions and treatment sessions.
How does dynamic feedback work in gating?
Dynamic feedback in gating systems is established by correlating the signal from a respiration-monitoring device with the internal location of the target. Because respiratory gating is a dynamic feedback process, existing static test phantoms and tools cannot be used to fully evaluate a gating system. In order to test in vivo dosimetry and target localization for gating systems, dynamic test phantoms that simulate respiration are needed. Such test phantoms are needed for acceptance testing, commissioning, and ongoing QA of clinical respiratory gating treatment programs.
What organs move with breathing?
The lungs, esophagus, liver, pancreas, breast, prostate, and kidneys, are known to move with breathing. The impact of this motion on CT and MR image quality, as well as on radiotherapy dose planning and delivery, has prompted medical physicists and clinicians to study the motion using a variety of imaging modalities. We provide here a survey of published observations on organ motion due to respiration and other influences. The survey is not exhaustive, but is intended to provide guidelines for accommodating the motion during treatment.
How does radiation therapy work?
Internal radiation therapy uses a sealed source of radiation that is implanted (put inside your body) where the cancer is located. Depending on the type of implant used, your body may give off a small amount of radiation for a short time.
Why is it important to keep radiation exposure to the people around you?
If you're getting systemic radiation treatment , sometimes safety measures are needed to protect the people around you. This is because the radioactive materials can leave your body through saliva, sweat, blood, and urine and that makes these fluids radioactive. It's very important to keep radiation exposure to the people around you as limited as possible.
Why is it important to know that not all radiation treatments work the same way or have the same safety precautions?
This is because they must meet certain regulations that help to limit their exposure to radiation when caring for patients who need treatment and imaging tests. It's important to know that not all radiation treatments work the same way or have the same safety precautions.
What is external beam radiation?
External radiation therapy is given from an outside source, involves a beam of radiation aimed at a part of the body, and affects cells in your body only for a moment. Because there’s no radiation source inside your body, you are not radioactive at any time during or after treatment.
How to avoid radiation therapy?
Avoid contact with pets for a specific amount of time. Avoid public transportation for a specific amount of time. Plan to stay home from work, school, and other activities for a specific amount of time. Again, the information here describes some safety concerns of different types of radiation therapy.
How long after radiation treatment should you follow safety precautions?
In most cases for systemic radiation treatment, the safety precautions must be followed only the first few days after treatment.
How long after radiation treatment should you wash your clothes?
In most cases for systemic radiation treatment, the safety precautions must be followed only the first few days after treatment. Here are examples of things you might be told to do if you're getting systemic radiation treatment: Wash your laundry separately from the rest of the household, including towels and sheets.
