The draining lava left long, tube-like caverns. Of the four caves in this particular cluster, only Boyd Cave is now open to hikers. Arnold Ice Cave is filled with ice. Skeleton and Wind Cave were open to hikers until 2007, when they were gated closed to prevent vandalism and protect hibernating bats.
Dyspnea is translated from medical terminology to mean difficult breathing, where some disease, reaction, or other stimulant has caused breathing to be obstructed or otherwiseâ¦ uneasy. Apnea means lack of or stopped breathing.
I don't think you can say they're the same thing. Dyspnea is difficulty breathing, or labored breathing. Shortness of breath is... just feeling of short of breath, like when you just did a two-mile run. You can feel short of breath but not necessarily have difficulty breathing.
