We believe that informed clients are empowered clients.
Understanding Acute Mountain Sickness (AMS)
Among altitude-related health concerns, acute mountain sickness (AMS) is the most common. AMS typically occurs when ascending to altitudes above 2500 meters, but it can affect individuals at lower altitudes if they are highly susceptible. Risk factors include the rate of ascent, the altitude reached, and individual predisposition. Recognizing the symptoms of AMS is vital for early detection and appropriate management. Headache, nausea/vomiting, fatigue, and dizziness/light-headedness are key indicators of AMS. Understanding these symptoms and their implications will empower you to take necessary precautions and seek timely assistance if needed.
The Lake Louise AMS Score (LLS)
To assess the presence and severity of AMS, the Lake Louise AMS score is widely used. This scoring system enables guides and healthcare professionals to evaluate your condition objectively. The Lake Louise AMS score considers four major symptoms: headache, nausea/vomiting, fatigue, and dizziness/light-headedness. By assigning scores to each symptom and considering the total score, we can determine the presence and severity of AMS. Our medical check-up form has been revised to provide you with a clear understanding of this evaluation process, allowing you to actively participate in your own health assessment during the expedition.
Psychotic Episodes at High Altitudes
Psychotic episodes have been reported in mountain literature during exposure to very high or extreme altitudes. While not systematically analyzed as a distinct clinical entity, it is essential to acknowledge the potential risk. Our guides are experienced to recognize and manage such situations to a certain extent, ensuring your safety throughout the expedition. Although rare, being aware of this possibility will help you approach high-altitude environments with preparedness and caution.
Pulse Oximeters: Monitoring Your Pulse and Oxygen Levels
Pulse oximeters are invaluable devices used to monitor two vital parameters: your pulse rate and oxygen saturation levels. These non-invasive tools provide real-time measurements, allowing for continuous evaluation of your physiological well-being in high-altitude environments. Pulse oximeter is solely used and is not enough. They are accurate to a certain extent but can be used partially to evolute AMS. As for us, we partially use it for evaluation.
Pulse Rate Monitoring
Your pulse rate, also known as heart rate, reflects the number of times your heart beats per minute. Monitoring your pulse rate during high-altitude expeditions provides crucial insights into your cardiovascular response to altitude-related stressors. Our guides will assist you in using a pulse oximeter to track your pulse rate regularly, ensuring that it remains within a healthy range for your specific circumstances. The normal pulse rate, also known as the heart rate, varies depending on factors such as age, fitness level, and overall health. However, for adults, the normal resting heart rate typically falls within the range of 60 to 100 beats per minute (bpm). It's important to note that highly trained athletes or individuals with excellent cardiovascular fitness may have resting heart rates below 60 bpm, sometimes as low as 40 bpm. This is because their hearts are more efficient and can pump a greater amount of blood with each beat.
Oxygen Saturation Monitoring
Oxygen saturation refers to the percentage of hemoglobin in your blood that is carrying oxygen. This parameter is particularly important at high altitudes, where the availability of oxygen is reduced. Monitoring your oxygen saturation levels using a pulse oximeter allows us to assess your respiratory function and the adequacy of oxygen delivery to your body's tissues. Our experienced guides will guide you on the appropriate oxygen saturation levels to maintain during your high-altitude expedition.
Interpreting Pulse Oximeter Readings
While pulse oximeters provide valuable data, it's important to understand how to interpret the readings accurately. Our guides will explain the significance of oxygen saturation levels and pulse rates in the context of high-altitude environments. They will also discuss potential factors that may affect the readings, such as individual variations, physical exertion, and environmental conditions. By comprehending the nuances of pulse oximeter data interpretation, you can make informed decisions regarding your health and well-being during your high-altitude journey.
Here are the commonly used oxygen percentages and their corresponding saturation levels:

Breathing Challenges at High Altitudes
One of the most noticeable effects of high altitudes is the decreased oxygen availability in the air. As a result, individuals may experience difficulties in breathing, especially during physical exertion. Shortness of breath, rapid breathing, or a feeling of breathlessness can occur. It's important to be aware of these challenges and adjust your activities accordingly. Our guides will provide guidance on pacing yourself, taking regular breaks, and employing breathing techniques to manage and adapt to the changes in oxygen levels.
Appetite Changes and Hydration
At high altitudes, appetite changes are common among individuals. Some may experience a decreased appetite, while others may feel increased hunger. It's crucial to listen to your body and maintain proper nutrition and hydration levels. Even if your appetite is reduced, it's important to consume enough calories and stay hydrated to support your body's needs. Our guides will provide nutritional recommendations and encourage you to drink plenty of fluids to prevent dehydration and maintain your energy levels.
Medication Considerations
If you have any pre-existing medical conditions or take medications, it's essential to discuss them with your healthcare provider before embarking on a high-altitude expedition. Certain medications may have interactions or side effects that can be exacerbated by the altitude. Your healthcare provider can provide specific guidance on adjusting your medication regimen, if necessary, and ensure that you have an adequate supply for the duration of your trip. It's crucial to inform our guides about any medications you are taking to ensure your safety and well-being during the expedition.
Monitoring and Adaptation
During your high-altitude journey, our guides will regularly assess your breathing patterns, appetite, and overall well-being. They will be attentive to any significant changes or symptoms that may indicate altitude-related issues. By keeping an open line of communication with our guides, you can promptly address any concerns or difficulties you may experience. Our team is experienced in managing altitude-related challenges and will provide necessary support, including advice on managing breathing difficulties, maintaining proper nutrition, and addressing medication-related concerns.
