Q. How do I check my oxygen level at home without a Pulse Oximeter?
A. If you do not have a portable finger pulse oximeter in your home, you can also learn how to assess signs and symptoms of low oxygen levels. Two classic signs of a low oxygen level are a rapid heart rate and a fast breathing rate. An average heart rate is 60–100 beats per minute and an average breathing rate is 12–20 breaths per minute. However, under low oxygen conditions, body responses include an increase in heart rate and breathing rate. Another
sign of a low blood oxygen level is cyanosis or a bluish color change on your lips, nose, or fingertips. As your body loses oxygen, the blood cells in your body change colour in your bloodstream to a dark blue, which can be seen from the outside of your skin if it is severe. Cyanosis is typically a late sign of low oxygen levels and is considered a medical emergency. If you notice this bluish discolouration, you should immediately visit the
nearest hospital.
Q. Do we see many cases of silent hypoxia in this wave? How can this be addressed?
A. Silent hypoxia or happy hypoxia is referred to as the early stage of COVID-19. As the oxygen level drops, one may start feeling shortness of breath, confusion, and other symptoms. Keep watching for these signs and do not ignore them. This is true for young people as well. If you monitor low oxygen level, change in lip colour from natural to blue or persistent sweating, consult the covid helpline or doctor. They could be the early sign of silent hypoxia.
Q. In brief, how can proning help enhance blood oxygen levels?
A. Proning is a medically accepted process to improve the distribution and exchange of oxygen in the lungs. A patient is safely placed from their back onto their abdomen (stomach), i.e., having face down to improve breathing and oxygenation. It has been shown beneficial for COVID-19 patients with compromised breathing comfort, especially during home isolation.
Q. Is pure oxygen used in hospitals?
A. Medical oxygen contains high purity oxygen used for medical treatments and is developed for use in human body. Cylinders contain a compressed oxygen gas and no gases are allowed in the cylinder to prevent contamination.
Q. What is the use of Medical Oxygen?
A. Oxygen is used for treatment in hospitals. Hence, it is considered a drug or a
pharmaceutical product.
Q. What is the need for Medical Oxygen?
A. The human body requires oxygen to survive, and typically, we breathe in from air. However, if you have lung disease or other medical conditions such as COVID-19, you may not get enough oxygen due to compromised lungs. That can leave you short of breath and cause problems with your heart, brain, and other parts of your body.
Q. Can breathing 100 per cent oxygen harm your body?
A. Yes. Breathing 100% oxygen also eventually leads to collapse of the alveoli (atelectasis).
