What do you do if a person has very shallow and ineffective breathing?

If a person has very shallow and ineffective breathing, first ensure their safety by moving them to a comfortable position, preferably sitting up. Encourage them to take slow, deep breaths by demonstrating abdominal breathing—inhale deeply through the nose, allowing the diaphragm to expand, and exhale slowly through the mouth. If their condition does not improve or worsens, seek medical assistance immediately, as this could indicate a serious underlying issue.
