Northern Nevada's stunning lakes, including Lake Tahoe, with its average summer water temperature of 50 degrees, present a potential risk of hypothermia. Unlike mild 50-degree air, water at the same temperature poses severe, life-threatening risks, including rapid-onset hypothermia and drowning. Awareness of the symptoms and taking proper precautions are crucial to prevent cold-water drowning. The 4 Phases of Cold-Water Drowning 1. Cold Shock Response: This response affects breathing and happens within the first minute. An automatic gasp reflex occurs in response to rapid skin cooling. If the head goes below water, water may be breathed into the lungs, resulting in drowning. A life jacket will help keep your head above water during this critical phase. Additionally, hyperventilation, like the gasp reflex, is a response to the cold and will subside. Panic will make this worse, so the key is to control breathing. 2. Cold Incapacitation: This response occurs within the first five to 15 minutes in cold water. In order to preserve core heat, vasoconstriction takes place decreasing blood flow to the extremities to protect the vital organs. The result is a loss of movement to hands, feet, arms and legs. Unless a life jacket is being worn, the ability to stay afloat is next to impossible. 3. Hypothermia: Important to note, it can take 30 minutes or more for most adults to become hypothermic. So there’s time to take action and survive. Keeping panic at bay is critical, as you have more survival time than you think. Symptoms include: Shivering Slow and shallow breathing Confusion Drowsiness or exhaustion Slurred speech Loss of coordination Weak pulse 4. Circum-rescue Collapse: This experience can happen just before rescue and is not well understood. Symptoms range anywhere from fainting to death. Some experts believe an abrupt drop in blood pressure may cause this final stage of cold water drowning, post-rescue. Additional Safety Tips and Helpful Resources Always wear a personal flotation device as well as a wetsuit or drysuit. Your personal flotation device is the most important piece of water safety gear. Try not to panic as the first phases will subside. Controlled breathing is to staying calm. Research suggests the body can withstand the cold longer than we think. The Heat Escape Lessening Posture (HELP) is a position which helps conserve energy if you’re wearing a personal flotation device. By hugging your knees to your chest, this posture helps maintain body heat for some time.

Your heart is the muscle in charge of pumping blood to your entire body. This vital organ is made up of chambers, valves and blood vessels. Your heart valves work similarly to a one-way door: they open and close, controlling blood flow in the correct direction through the heart chambers.   For patients who have been diagnosed with a heart-related condition like aortic valve stenosis (narrowing), it is important to know treatment options. Most might think open-heart surgery is the only way to treat a heart valve, but many hospitals, including Renown, also offer a minimally invasive procedure called a Transcatheter Aortic Valve Replacement (TAVR). Dr. Abhilash Akinapelli of Renown Institute for Heart & Vascular Health shares his answers to the top five TAVR questions:  1. What causes aortic valve stenosis?  Aortic valve stenosis can be caused by a variety of factors. The main reasons being wear and tear of the valve due to aging; genetically abnormal heart valve (bicuspid aortic valve); long-standing high blood pressure; and other reasons like radiation exposure.   2. Am I a candidate for TAVR?  Renown’s heart care teams are made up of your primary care provider, cardiologist and cardio thoracic surgeon. They will evaluate if patients are a good candidate for the TAVR procedure by performing a variety of screenings and tests. Some of these include:   Echocardiogram  Electrocardiogram (ECG or EKG)  Chest X-ray Exercise tests or stress tests  Cardiac computerized tomography (CT) scan  Cardiac catheterization  3. What are the advantages of the TAVR procedure?  The Transcatheter Aortic Valve Replacement (TAVR) procedure is much less invasive than open heart surgery, otherwise known as a Surgical Aortic Valve Replacement (SAVR). Patients can typically return to their normal lifestyles within a week after leaving the hospital.   During the TAVR procedure, a stent valve mounted on a balloon is advanced to the heart through the blood vessels in the groin without any incision. Once in position, the balloon will be inflated to firmly expand the new valve inside the diseased old valve, pushing it away to the sides. Once the new valve is in place, it begins working immediately and the deflated balloon is removed. The surgical procedure is approximately one hour long. Patients can get up and walk after four hours and will be discharged the following day if no complications arise. Compared to a SAVR, recovery time is much shorter and less risky for patients above the age of 75. A big advantage for anyone who fits under the criteria for a TAVR.  4. Is the procedure painful?  The TAVR procedure is not surgery, but you will still be asleep during the procedure. Since no incision is made, it is essentially a painless procedure. Patients may experience slight discomfort such as aches and pains at the entry site of the catheter.   5. Can I have an MRI and X-rays done after having a TAVR valve?  Yes, patients can have MRI scans and X-rays after TAVR.   For further questions and information about the TAVR procedure, please consult with your Renown heart care team at 775-982-2452 or through MyChart.

Find One Now Flu Shot Information Whitney Robinson, Renown Health Infection Prevention Expert Chills, body aches, fever and congestion; getting the flu isn’t fun. When you get a flu shot, you’re not just protecting yourself, you’re also helping reduce the total flu cases and hospitalizations. The ideal time to get your flu shot is September through October. This timing allows the vaccine to provide the strongest protection during the length of flu season. However, getting the vaccine later is better than not at all as it's still flu season well into spring. Flu Symptoms In general, influenza (flu) is worse than the common cold and shares symptoms with COVID-19, causing mild to severe illness, and at times can lead to death. Symptoms include: Fever or feeling feverish/chills (not everyone will have a fever) Cough and/or sore throat Runny or stuffy nose Headaches, muscle or body aches Fatigue (tiredness) Vomiting and diarrhea, though this is more common in children than adults Who Needs a Flu Shot? Almost everyone. The Centers for Disease Control and Prevention (CDC) considers it the first and most crucial step in protecting against the flu virus. Therefore, they recommend the yearly flu shot for those six months of age and older. Does the Flu Shot Help with COVID-19? The short answer is no. However, flu vaccines can reduce the risks of flu illness and hospitalization. Therefore, it is crucial for you to get your flu shot to not only protect yourself and the community, but also to help conserve vital, local healthcare resources. CDC Resource: Who Needs a Flu Vaccine and When Kids, the Elderly and Flu Shots  Vanessa Slots, M.D., Renown Medical Group The flu is not a passing cold. It is a serious illness that takes lives every year and it happens like clockwork. The onset of flu season is fall and lasts through winter into the spring months. This lung illness is caused by viruses, with yearly outbreaks occurring worldwide. No one is immune, and anyone can catch  to the flu. Flu Signs and Symptoms Quick onset of fever Headache Body aches and fatigue along with respiratory symptoms including cough Sore throat and nose Who's at Risk for the Flu? Children and the elderly are at greater risk of complications from the flu, specifically toddlers less than two years old. At this age, their immunity is still developing. Seniors over 65 are also at increased risk because their immune systems have weakened with age. The severity of a child’s symptoms depends on age and prior exposure to the virus. With young children, for example, the flu is more problematic since they cannot talk and communicate their symptoms. As a result, children often experience higher fevers, which can lead to seizures or convulsions. This can be coupled with issues such as nausea, vomiting, diarrhea and poor appetite, all of which put children at risk of dehydration and other complications that can require hospitalization. An average of 20,000 children are hospitalized for flu each year. Pre-Existing Health Issues Ongoing health conditions including asthma, heart conditions, diabetes and more can intensify flu symptoms. Still, many children without risk factors can experience severe flu complications. CDC Resource: Flu Information for Parents Pregnant Moms and Flu Shots Tamsen Carson, PAC, Surgical First Assistant, OB/GYN, Renown Medical Group “During pregnancy, your immune system wards off infection for your baby, leaving you more susceptible to infection and adverse health conditions,” Tamsen explains. She   highly recommends flu shots for ALL women during pregnancy. You must receive the injected vaccine versus the live vaccine, a nasal spray, which can cause the flu to occur. Passing Flu Immunity on to Your Baby Also, remember that you will also be able to pass the immunity onto your baby if you breastfeed, which will protect your baby from the flu.
