Please be sure to teach the students only restoratives and no intense poses, no matter what the doctor says. Please also apply common sense to my suggestions and omit anything that causes nausea or giddiness, or modify it using props.
Allow the students to do mild standing poses with wall support behind them. In general, front bends and backbends are all right if the students are fully supported and not straining.
The important poses are those that open the chest and mildly stimulate the immune system. These include fully supported Sarvangasana (Shoulderstand), Setu Bandha Sarvangasana (Bridge Pose), Viparita Karani (Legs-Up-the-Wall Pose), lying on cross bolsters with arms stretched out sideways (sometimes called Supported Savasana, or Supported Bridge Pose), and Pranayama posture (with legs and buttocks on the floor, a bolster supporting the upper body from the kidneys upward, a small pad under the head, and arms in Savasana).
Throughout the restoratives and the gentle practice, please ask the students to be conscious of their breath and to breathe deeply and fully, in both inhalation and exhalation. Oxygenating the blood is very important for the body's fight against disease, and deep breathing while visualizing the blood becoming oxygenated will increase energy reserves and revitalize their fatigued bodies.
