HEART Massaging in prone posture by oneself and Pink CPR in standing or lying posture by oneself proposed by PhysiologyWalla! These manoeuvres help to perfuse the heart with oxygenated blood by external compression of heart and by internal ripples of blood in aorta respectively! PhysiologyWalla advocates for these physiological manoeuvres by oneself daily for walking and talking people with nearly normal heart functions to strengthen own heart rather than in emergency situations! How & Why to do oneself daily?! Welcome and Thanks! ☺️ 🙏
