One of SA’s top Covid-19 experts has advised South Africans to \u201cseek help immediately\u201d if they have chest pains and shortness of breath.<\/p>\n\n\n\n
\u201cThe main symptoms of low oxygen are chest pain and difficulty with breathing,\u201d explains Professor Shabir Madhi, who is on the Covid-19 advisory council to the department of health and is head of the vaccine trials in the country.<\/p>\n\n\n\n
He adds that \u201cdizziness\u201d follows as one fails to get enough oxygen to the brain.<\/p>\n\n\n\n
He said people should \u201cseek assistance immediately\u201d if they are experiencing \u201cchest pains, shortness of breath, lightheadedness or confusion\u201d, as these are all \u201ctelltale signs that your oxygen levels are not adequate\u201d.<\/p>\n\n\n\n
Rapid breathing is also a sign.<\/p>\n\n\n\n
\u201cIf you are taking more than 20 breaths per minute, then you need to receive oxygen,\u201d he told TimesLIVE.<\/p>\n\n\n\n
He said it is \u201cdifficult to quantify\u201d if many South Africans are failing to seek help when they should, but suspected that \u201csome are delaying seeking care because they\u2019re too afraid of what might happen\u201d.<\/p>\n\n\n\n
Across the globe, between 12% to 14% of those who are hospitalised lose their lives and, says Prof Madhi, \u201cSouth Africa is in the same ballpark figures of what has been observed in other countries\u201d.<\/p>\n\n\n\n
Apart from monitoring these symptoms, another way to check oxygen levels is with a pulse oximeter, but these are not readily available to the public in South Africa.<\/p>\n\n\n\n
\u201cA pulse oximeter is good to have but they aren’t readily available,\u201d said Madhi. \u201cIt\u2019s a medical device so very few pharmacists will have it. But, the symptoms on their own will tell you if you need oxygen.\u201d<\/p>\n\n\n\n
It\u2019s a small device that clips onto your finger and measures your oxygen saturation levels, and outside of hospitals, one is most likely to see them in an ambulance or a nursing home.<\/p>\n\n\n\n
You need to \u201cmake sure your hands are warm\u201d while using one, says Madhi.<\/p>\n\n\n\n
Nail polish can also interfere with the readings, so the device should be used without any.<\/p>\n\n\n\n
\u201cYour saturation should be above 95,\u201d says Prof Madhi, \u201cif it is under 93 you need to get oxygen.\u201d<\/p>\n\n\n\n
While the public may also attempt to measure their own oxygen with smartphone apps or fitness trackers, a British general practitioner, Ann Robinson told The Guardian<\/em>, \u201cThere is no evidence to say that smartphone apps or fitness trackers are accurate enough for this purpose.\u201d<\/p>\n\n\n\n In a small percentage of Covid-19 cases, a person can suffer from what\u2019s known as silent hypoxia \u2014 where there is no way of knowing that oxygen levels have dropped to very dangerous levels.<\/p>\n\n\n\n This was first reported in Chinese studies but there was no indication of how commonly this occurs.<\/p>\n\n\n\n Cases then showed up in Europe and the UK.<\/p>\n\n\n\n A\u00a0letter\u00a0to the\u00a0British Journal of Anaesthesia<\/em>\u00a0suggests that silent hypoxaemia could result from one\u2019s oxygen and carbon dioxide being low, because if only your oxygen is low, it is high blood carbon dioxide that usually causes breathlessness.<\/p>\n\n\n\n The WHO advises that if you have minor symptoms, such as only a slight cough or a mild fever, \u201cthere is generally no need to seek medical care\u201d. It advises such people to stay at home, monitor their symptoms, and follow national guidance on self-isolation.<\/p>\n\n\n\n The WHO advises that people get medical attention immediately if they have any breathing difficulties or pain or pressure in the chest.<\/p>\n\n\n\n
