Airplane flights can be a great way to travel, but they can also pose certain risks, particularly when it comes to medical emergencies. To help ensure a safe and comfortable flight, it's important to be prepared and know how to handle potential medical issues that may arise. One of the most important things you can do to avoid medical emergencies on an airplane flight is to make sure you're in good health before you depart. This means getting a thorough check-up from your doctor, especially if you have any underlying health conditions that may be exacerbated by flying. It's also a good idea to bring any necessary medications with you and to inform the flight crew of any medical conditions you may have. Another key step in avoiding medical emergencies on an airplane flight is to stay hydrated. Airplanes are typically kept at a low humidity, which can dehydrate your body quickly. To combat this, make sure to drink plenty of water before and during the flight. Avoiding alcohol and caffeine, which can also dehydrate you, is also a good idea. Deep vein thrombosis (DVT) is a serious condition that can occur during long-haul flights, and can cause blood clots to form in the legs. To prevent DVT, it's important to get up and move around the cabin as much as possible, and to do exercises to keep your blood flowing. You can also wear compression stockings, which can help to reduce the risk of DVT. Another important step in avoiding medical emergencies on an airplane flight is to be aware of the signs and symptoms of altitude sickness. Altitude sickness can occur when you're flying at high altitudes, and can cause symptoms such as headache, nausea, and fatigue. To prevent altitude sickness, it's important to breathe deeply and stay well-oxygenated. If you experience any symptoms of altitude sickness, inform the flight crew immediately. Finally, it's important to be prepared for any medical emergencies that may occur on an airplane flight. This means knowing where the emergency medical equipment is located, and how to use it. It's also a good idea to bring a first aid kit with you, in case you need to treat any minor injuries or illnesses. In conclusion, there are many steps you can take to avoid medical emergencies on an airplane flight. By being prepared, staying hydrated, preventing DVT, and being aware of the signs and symptoms of altitude sickness, you can help to ensure a safe and comfortable flight. Remember to always inform the flight crew of any medical conditions you may have and to bring your necessary medications with you. Dr. A. Arrazaghi MD,FRCPC
