There are reasons to have the head of the medical bed elevated:
#1 This helps when eating in bed. People need to be in the most natural position for swallowing safely. Food and drink can cause coughing or choking if a person in not in the most upright position.
#2 During the declining in health state or the dying process respiratory difficulty is common. The body may be too weak to cough or clear phlegm from the upper airway. Laying flat may also contribute to feeling like they just don’t “get enough air.”
#3 Preventing or postponing “aspiration pneumonia” is the third reason. I will talk about what “aspiration pneumonia” is in another entry.
