Even when fires burn outside our area, the air quality in the region can reach dangerous levels. Our expert explains how to maintain your lung health when fire season strikes. It’s a sight we know all too well as northern Nevadans — a hazy or thick layer on the horizon when smoke rolls in from nearby fires. Sometimes the smoke is more evident than others, but it’s important to remember, even when the smoke may not be as visible across the valley, it still impacts our air quality. The last week or so, our air quality has been in the “unhealthy for sensitive groups” range, which can be dangerous for people who are sensitive to air pollution. Air Quality Changes: Who’s at Risk? Renown Pediatric Pulmonologist Sonia Budhecha, M.D., explains certain people are especially at risk when smoke moves in: Older people, whose lungs are not as healthy as they used to be Young children, whose lungs are still developing People with heart and lung disease including asthma, COPD and emphysema “Smoke and haze from fires carry particulates that can get into your respiratory system and eyes, which can be a danger for all ages,” Dr. Budhecha says. How You Can Protect Yourself Until the smoke clears and the air returns to the “good” range, it is best to follow these tips to protect yourself and your family: Stay indoors and keep windows closed Turn on the air conditioning to recirculate clean air Drink plenty of fluids to help your body flush out any toxins you inhale Additionally, all community members should reduce their physical activity and try to prevent heavy exertion outside. If you or a loved one has a heart or lung disease, avoid physical exertion altogether because smoke can aggravate these conditions. “People with heart disease may experience shortness of breath, chest pain, palpitations or fatigue,” Dr. Budhecha says. “People with lung disease may also have shortness of breath, chest discomfort, wheezing, phlegm or a cough.” Smoky Signs and Symptoms Smoke can also impact healthy people — irritating your eyes, nose or throat. And in some cases, inhaling smoke can lead to bronchitis. When haze moves into our area, keep an eye out for these symptoms: Burning or stinging eyes Runny nose Cough or scratchy throat Headaches Wheezing Shortness of breath Difficult taking a full breath Chest heaviness Lightheadedness Dizziness If experiencing any of the above symptoms, seek medical attention or call your doctor for advice. Sometimes, these symptoms do not appear for as long as 24 to 48 hours after smoke inhalation. For those that have pre-existing lung or heart conditions, consult with a health care provider on action or management plans. To schedule an appointment Visit Renown Pulmonary Medicine, or call 775-982-5000. Understanding Our Air Quality The Air Quality Index (AQI) is broken down by large (PM10) and small (PM2.5) particulates. According to Dr. Budhecha, large particulates are usually ones that can be seen and smelled. They can damage your eyes and nose but don’t often get deep in the lungs or blood vessels.   “The more dangerous ones are PM2.5, which can’t always be seen or smelled,” Dr. Budhecha says. “Any time the AQI is above 51, children with lung or heart disease should not be outdoors.” For the latest air quality update in your area, visit AirNow.gov or call (775) 785-4110.

Lung cancer is the leading cause of cancer deaths in both men and women in the U.S. The good news is the five-year survival rate increases dramatically if lung cancer is treated before spreading to other parts of the body. Julie Locken, MD, of Renown Health Imaging, explains more. What are the signs and symptoms of lung cancer? As you might expect, most lung cancer symptoms appear in the chest and can affect your breathing. Watch for signs such as: Persistent cough Constant chest pain Shortness of breath Wheezing Bloody or rust-colored phlegm Hoarseness Swelling of the neck Pain or weakness in the shoulder, arm or hand Recurring pneumonia, bronchitis or other lung infections Loss of appetite and loss of weight can also be signs of lung cancer That said, there are usually no symptoms in the early stages of lung cancer, which means getting screened can truly be a lifesaver. If you have a history of smoking, you should get screened as a precaution.  What are the risk factors of lung cancer?  Around 80% of lung cancer cases stem from a history of smoking tobacco. But there are other known causes, such as secondhand smoke, radon, asbestos and diesel exhaust. It’s important to do what you can to eliminate exposure to all of these to reduce your lung cancer risk.  People with an immediate relative – a parent, sibling or child – diagnosed with lung cancer and people between 50 and 80 years old are also at higher risk and may need to consider screening.  People who are at the highest risk are those with a history of smoking tobacco, particularly smokers who averaged one pack of cigarettes per day for 20 years or more, as well as former heavy smokers who quit in the last 15 years.

COPD (chronic obstructive pulmonary disease) is a progressive lung condition often mistaken for typical aging signs, like shortness of breath and coughing. While smoking and pollution can contribute to its development, lifestyle changes and medications can help manage its progression. Diagnosis typically involves lung function tests, chest X-rays, or CT scans, with treatments available through a pulmonologist or primary care provider. Renown’s Pulmonary Rehabilitation Program offers insights into living with COPD. What is COPD? According to the COPD Foundation, it is an umbrella term used to describe progressive lung diseases including: Emphysema: Damage to the small air sacs in the lungs (alveoli). Chronic Bronchitis: Irritation and swelling of bronchial tubes, causing shortness of breath and coughing for long periods of time. Asthma (non-reversible): When asthma medications cannot reduce swelling in the airways. COPD Risk Factors Smoking is the most significant COPD risk factor, and the American Lung Association (ALA) says it accounts for nearly 90 percent of cases. If you are a smoker, it is essential to seek help and quit. Other COPD risk factors include: Air pollution Genetics Second-hand smoke Chemical, fumes or dust in the workplace How Can You Protect Yourself?  Stop smoking Renown Health provides support offering 4-week Smoking Cessation Virtual Classes, free of charge! Sign up today. Use natural cleaning products Many household chemicals, especially those containing bleach, can irritate the lungs – a condition called, chemical pneumonitis. Stay away from all types of smoke This includes smoke from fireplaces. Likewise, plan to stay indoors when it is smoky outside, or air quality is poor. Get active Of course, it’s never too late to start an exercise program. When exercising your heart pumps, circulating your blood and sending oxygen to every part of your body. Notably it strengthens your lungs, making it easier to breath. Talk to your doctor to see if you are healthy enough to begin exercising. Eat a healthy diet Surprisingly what you eat can affect your breathing. The American Lung Association encourages those with COPD to watch their sodium intake, eat smaller, more frequent meals (instead of three large ones), limit high fat foods and drink plenty of water. Avoid scented products Perfumes, aerosol sprays and plug-in air fresheners can trigger flare-ups. Get a flu shot Did you know chronic lung conditions, as well as, heart disease, cancer and diabetes, can be made even worse by the flu? Now is the time to get your flu shot for the season if you haven’t already. Renown’s Pulmonary Rehab staff is certified through the American Association for Cardiovascular and Pulmonary Rehabilitation (AACVPR).  Recently, Renown Regional Medical Center successfully completed a disease specific COPD certification survey by The Joint Commission. For two accreditation cycles in a row, the COPD Program has had zero findings during the rigorous survey.

Whether you're a parent, grandparent, caregiver, or sibling, it's vital to recognize that drowning is the second leading cause of death among children," states Dr. Leland Sullivan, of Northern Nevada Emergency Physicians. "While we diligently work to protect children from water-related accidents, there's a lesser-known threat that often goes unnoticed—dry drowning, also known as delayed drowning. Surprisingly, many people remain unaware of its existence and potential dangers. Dry drowning defined Dry drowning is a side-effect of a near-drowning experience and includes spasms of the vocal cords and larynx — known as a laryngospasm. This occurs when the body attempts to shut down the passage of any liquid into the lungs. Unfortunately, it can also shut down the passage of air into the lungs and force fluid into the stomach and lungs. Often the condition is not discovered until it's too late — severe cases can cause death within one to 24 hours after a water incident occurs. Who is susceptible? Novice or first-time swimmers are at increased risk, as are children with asthma and known breathing issues. In addition, children who have had pneumonia or experienced acute respiratory distress syndrome are also at greater risk. To reduce these factors, caregivers should be exceptionally watchful of inexperienced swimmers. According to Dr. Sullivan, children under the age of 5 are most susceptible to drowning and often drown in residential swimming pools. Infants less than 1-year-old most often drown in bathtubs. What are the signs of a dry drowning episode? If your child has a near-drowning incident, a few moments of coughing until they calm down is normal. However, you should know the more severe signs and symptoms to watch for during the 24 hours following the incident, including: Persistent coughing Difficulty breathing and/or shortness of breath Chest pains Extreme fatigue and/or lethargy Change in typical behavior Face becomes pale   What is the treatment and prognosis for dry drowning? Dr. Sullivan recommends that all victims of near-drowning incidents seek medical attention, even if they have no symptoms. If caught early, dry drowning can be treated. If you think your child is experiencing a dry drowning episode, go to the nearest emergency room as quickly as possible — do not attempt treatment at home. Healthcare professionals will work to supply oxygen to your child's lungs to restore and regulate breathing.
