5 top things to know to protect you from vog.

At approximately 11:30 PM on November 27 an eruption began in the summit caldera of Mauna Loa volcano on the Big Island. Winds may carry volcanic gas and possibly fine ash downwind. Vog is a mixture of sulfur dioxide gas and particles.  Sensitivity to vog varies. Here are the five top things to do if you were bothered by vog. 

1. understand the hazard.  get familiar with monitoring websites and the forecast of Vog plume location depending on your location. Links are in the comments. Currently Hawaii air quality levels are good. Still highly sensitive individuals, such as premature infants, patients with asthma, respiratory problems, heart problems pregnant women, and young infants may be affected at these levels. 

2. This is the time to get out your asthma action plan.  keep your medication‘s handy make sure you have a refill of all your asthma medication‘s. If you don’t have any medication‘s but feel that you’ve been having symptoms please contact your doctor for a prescription.  

3. Stay indoors if there is vog and use an air cleaner or HEPA filter while indoors. 

4. limit strenuous activities.  

5. If driving through dense volcanic plume near Hawaii volcanoes national park close up your vehicle or leave the area if appropriate.  Temporarily close your windows and vent and turn your fan and air conditioner off. First of all please note that reports in the media of ash being abrasive to the lungs are not correct.Ash irritates the respiratory system but it will not scratch the lining of your lungs. If you’re concerned wear an N 95 mask to protect yourself from the ash, but keep in mind that these masks are not effective against volcanic gases. We do know from multiple studies from the past with one specific study of the acute impact of volcanic ash on asthma symptoms and treatment that 42% approximately of asthma patients may suffer exacerbation during a volcanic eruption. Compared to severe asthma patients, mild and moderate asthma patients were more at risk. It seems that severe asthma patients were not affected since they knew their asthma is severe and they took measures preventatively.

Happy Parents

    "I was so impressed with Dr. Irene Papaconstadopolous. Everything is at her practice is streamlined and organized. Paperwork all sent beforehand in an easy to use digital format. Communication was clear and office easy to access. Went for our 18 month old’s check up and it was the most time I have ever been able to spend with a doctor! She even administered the vaccines. She was thorough, friendly, and creative in approach to making my toddler comfortable and engaged. So happy to have a competent, friendly, organized, and WONDERFUL pediatrician on Maui. Such a blessing. Mahalo!"

    Dr. Irene is the kind of doctor United States badly need more of. I took my child to see her for a hard to troubleshoot chronic issue, and I was very surprised that instead of typical in the US approach of prescribing a medicine to treat the symptom and get you out of the door, she took the time to understand medical history, went over each possibility what could have been causing the issue, and proposed a few possible follow-ups how to zero in to the root cause. Her advice was very helpful and produced positive results. I highly recommend Dr. Irene Papaconstadopoulos.

    "I can’t express how grateful I am, as a mother of two young children, to have found such a wonderful pediatrician. Dr. Irene is knowledgeable, accessible, and above all, great with kids! Even though my girls have had to be poked and prodded on occasion, they still love Dr. Irene so much that they get excited to see her again - and that’s saying a lot. If you are looking for a pediatrician who you can trust with your children’s health, who can answer your questions, who gets back to you quickly, and who herself is an amazing mother, then you’ve found her! I’m so glad we have. ❤️"

    We love Dr. Irene with CHAMPS Pediatrics! My two daughters have been seeing her since 2018 and we trust her completely. She's extremely warm, understanding and takes her time to explain and answer any questions that you may have as parents. She is extremely fast with the text replies through the online portal (klara) as well, which is great for those forgotten questions in between visits. Dr. Irene is super sweet and efficient and truly cares about your experience and the welfare of your children. HIGHLY recommended!

    "Dr. Irene is the most caring, gentle, genuine Pediatrician. She is so kind and loving with my boys. She makes them feel so comfortable and they are even excited when we have an appt! She was so quick to respond on the Klara App to communicate with me even during a holiday weekend and answer my questions about my son. She takes time to go over everything and answer all my questions and concerns, every time we've met with her. I've never felt rushed. I highly recommend her! She's been so great caring for my family. I feel so blessed to have been referred to her!! Thank you Dr. Irene, for caring for my kids!"
