Helium is less soluble in blood than nitrogen at high pressure.<\/p>\n<p>When a diver descends, the pressure of the water increases. This increase in pressure causes the gases in the diver&#8217;s blood to dissolve more easily. Nitrogen is one of the gases that dissolves in the blood. As the diver descends, more and more nitrogen dissolves in the blood. If the diver ascends too quickly, the nitrogen bubbles out of the blood too quickly, which can cause decompression sickness, also known as the bends.<\/p>\n<p>Helium is less soluble in blood than nitrogen. This means that it does not dissolve in the blood <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> as easily.
