The pandemic took a tragic turn when the second wave of coronavirus hit millions of people in India. Not only did it claim many lives, but it also left a considerable number of people gasping for breath. As we know, COVID-19 is a respiratory illness and takes a massive toll on our lungs and other parts of the body. In severe COVID patients, it can lead to a drop in oxygen levels, making it difficult to breathe and leading to chest pain. But what about those people who have no pain, no aches and no external signs of low oxygen levels in their blood, but are diagnosed with it at a later stage? The condition is called 'happy hypoxia' and here's everything you should know about this condition. Coronavirus is a respiratory disease which causes widespread inflammation in different parts of the body, including the lungs and the respiratory tract. It blocks the flow of oxygenated blood in the body, making it hard for the patients to breath. Experts believe that coagulation, or more simply, widespread clotting that takes place in the blood vessels in the lungs is what causes a drop in oxygen levels.

As the second wave of the Covid-19 pandemic rages, young people are now reporting severe lung infections and "unpredictable" symptoms. The latest to join the long list of COVID-19 symptoms is 'happy hypoxia' which means very low levels of oxygen in the blood. This condition is leaving medical professionals across the world baffled. According to ScienceMag, 'this one seems to defy basic biology'. Patients infected with the virus, with extremely low blood-oxygen levels are as comfortable as one can be with an illness, are scrolling on their phones, and talking to doctors normally. Clinicians have called them 'happy hypoxics'. Hypoxia refers to very low oxygen levels in the blood. The normal oxygen saturation in the bloodstream of a healthy person is above 95%, but COVID-19 patients display dangerous declines of as little as 40%. While hypoxia is a warning signal for imminent failure of vital body organs like the kidneys, brain, heart and is usually accompanied by prominent breathlessness, happy hypoxia does not prompt any such obvious external signs. As a result, in the initial stages of sickness, the COVID-19 patient, on the outside, appears to be alright and "happy". The proper medical term is "silent hypoxia." It happens when people are unaware they are being deprived of oxygen and are therefore showing up to the hospital in much worse health than they realize. How does this happen? Doctors speculate that, for some people, Covid-19 lung problems progress in a way that isn...

According to medical experts, Happy Hypoxia is a condition where the oxygen levels in the blood of a COVID-19 patient are low, but there are no external signs, symptoms, or pain that indicate this. Experts believe that coagulation (or clotting) occurs in the blood vessels of the lungs and this causes a drop in the oxygen level. When the blood in your body is deficient in oxygen, the condition is called hypoxia. The normal oxygen saturation level is between 94 and 99 percent, but when COVID-19 affects your lungs, it causes your oxygen levels to drop. Coronavirus is a respiratory disease that causes widespread inflammation in various parts of the body, including the lungs and respiratory system. It blocks the flow of oxygen-rich blood in the body, making it difficult for patients to breathe. Signs Of Low Oxygen Levels In COVID-19 Patients COVID-19 doesn't always cause oxygen levels to drop. Mild symptoms of COVID-19 may include fever, cough, and loss of smell and taste. However, people who have trouble breathing or experience shortness of breath at any time must be taken to the hospital. In normal cases, let's try to understand the signs of low oxygen levels in the blood among hypoxia patients. Common signs include shortness of breath, chest pain, confusion, change in the colour of lips (to a pale blue), and twitching of the nose. How To Detect Happy Hypoxia Experts recommend the continuous monitoring of oxygen levels in COVID-19 patients. Whether the patient has a mild infe...

May 14, 2021 Articles 218 Happy hypoxia refers to the condition where the patient has low oxygen saturation, but does not feel any symptoms of low saturation. As a result, they do not get alarmed until the disease has progressed and there is severe damage to the lungs. Younger patients often experience happy hypoxia in which they do not feel any breathlessness or related symptoms till oxygen saturation levels fall below 80. Usually symptoms are experienced when oxygen levels fall below 90 saturation.But in cases of happy hypoxia patients get alarmed late. • In a healthy person, the normal oxygen saturation is above 95%, but in certain patients suffering from COVID-19, the levels drop as low as 40%.In this case, there is a high likelihood of failure of vital organs like the kidneys, brain and heart. What’s alarming in the case of happy hypoxia in that no external signs are visible.This means that in the initial stages of COVID-19, the patient appears to be happy and healthy but on the inside, his lungs are in poor condition. Symptoms- • Along with common symptoms like • Colour of lips changes to blue • Changes in the colour of skin • Sweating profusely even when not performing any exercise or sternous work Patient suffering from happy hypoxia are able to walk and talk with ease.Their blood pressure, pulse readings also come in the normal range, even though their oxygen levels might have dipped well below 80% in most cases. Causes – • The primary cause of happy hypoxia is wi...

1 2 Study explains potential causes for 'happy hypoxia' condition in COVID-19 patients Findings could prevent unnecessary intubation Date: July 8, 2020 Source: Loyola University Health System Summary: A new research study provides possible explanations for COVID-19 patients who present with extremely low, otherwise life-threatening levels of oxygen, but no signs of dyspnea (difficulty breathing). This new understanding of the condition, known as silent hypoxemia or 'happy hypoxia,' could prevent unnecessary intubation and ventilation in patients during the current and expected second wave of coronavirus. Share: A new research study provides possible explanations for COVID-19 patients who present with extremely low, otherwise life-threatening levels of oxygen, but no signs of dyspnea (difficulty breathing). This new understanding of the condition, known as silent hypoxemia or "happy hypoxia," could prevent unnecessary intubation and ventilation in patients during the current and expected second wave of coronavirus. The condition "is especially bewildering to physicians as it defies basic biology," said Martin J. Tobin, MD, Loyola Medicine and Edward J. Hines Jr. VA Hospital pulmonologist and critical care specialist, and professor, Loyola University Chicago Stritch School of Medicine. Dr. Tobin is lead author of the study, "Why COVID-19 Silent Hypoxemia is Baffling to Physicians," appearing recently in the online American Journal of Respiratory and Critical Care Medicine. "...

Happy hypoxemia is severe hypoxemia (poorly responsive to supplemental oxygen) without dyspnea. This isn’t anything especially new – we have occasionally seen this since time immemorial. However, COVID is causing us to re-think how to manage this physiology. understanding the paradox of happy hypoxemia The key to understanding this is thinking about oxygenation and CO2 clearance separately. These problems typically run together, but under certain situations they can become divorced. (1) oxygenation Hypoxemia occurs when blood somehow passes from the right ventricle into the left ventricle without being fully oxygenated. This generally occurs in one of two ways: • Ventilation-perfusion mismatch (V-Q mismatch): Some parts of the lung have excess ventilation, whereas other parts have inadequate ventilation. Blood going to portions of the lung which are inadequately ventilated will be starved of oxygen. Alternatively, blood flowing to areas of the lung with excess ventilation will not be saturated over 100%. Taken together, the net result is hypoxemia. Increasing the concentration of inhaled oxygen generally fixes this problem – because even poorly ventilated areas of the lung will now get enough oxygen. • Shunt physiology: Blood flows from the right ventricle to the left ventricle without ever coming into contact with oxygenated alveoli at all. Examples include an anatomic abnormality (e.g., ventricular septal defect) or complete dysfunction of parts of the lung (e.g., mucus ...

Written by |Updated : December 31, 2020 8:05 AM IST • • • • • It's been a year now since the Covid-19, the disease caused by the novel coronavirus, emerged in China's Wuhan city. But many questions still remain unanswered. Although most Covid-19 patients have mild to moderate symptoms, the disease can cause severe medical complications in some people. Common complications of Covid-19 include Happy hypoxia is one of the physiopathological characteristics of Covid-19 that has most baffled the scientific and medical community. Why is it called happy hypoxia? For a normal person, the blood oxygen saturation level (the amount of hemoglobin carrying oxygen) is around 95 percent or more. Hypoxemia is a condition in which the blood saturation levels drop below 94 percent. Also Read • • • Patients with blood oxygen levels below 90 percent, which is considered too low, may experience symptoms like Cause of happy hypoxia found Researchers and doctors have been trying to understand the causes of happy hypoxia in Covid-19 patients. Now, researchers from the University of Seville in Spain have come up with an explanation for the condition. They say that infection in carotid bodies by SARS-CoV-2, the virus responsible for the pandemic, may be the cause of the decreased blood oxygen levels in many Covid-19 cases. Carotid bodies are sensory organs located on either side of the neck next to the carotid artery. They detect the drop in blood oxygen and send signals to the brain to stimulate t...

Various mysterious forms of fatal diseases in patients with COVID-19 have been coming to light during the second wave of COVID-19. Doctors are alarmed with an increasing number of youngsters being admitted to hospitals with ‘Happy Hypoxia’ which is being deemed as a ‘silent’ killer in COVID-19 patients. What is Happy Hypoxia? •Medical experts explain Happy Hypoxia as a medical condition in which patients suffering from COVID-19 with extremely low blood-oxygen levels are not exhibiting any symptom of a shortage of oxygen. •These people grouped as ‘Happy Hypoxics’ by the doctors are experiencing a drop in oxygen levels, failure of organs internally but still, show no external symptoms. Most of them are normally sitting, conversing, and using phones. •COVID-19 patients, especially youngsters, with happy hypoxia may not exhibit symptoms of breathlessness till a much later stage of the infection and crash suddenly. •Generally, a patient infected with COVID-19 shows oxygen saturation levels declining up to 40 percent, in some cases even lower. The healthy oxygen saturation level is above 95 per cent. How is Happy Hypoxia identified? •Medical experts highly advise monitoring blood oxygen levels with a pulse oximeter even if a COVID-19 patient is not exhibiting breathlessness but only fever, cough, sore throat, etc. •Medical experts say that in addition to regular COVID-19 symptoms, patients with happy hypoxia will exhibit skin discolouration to purple or red, change in lip colour...

Hypoxia is low levels of oxygen in your body tissues. It causes symptoms like confusion, restlessness, difficulty breathing, rapid heart rate, and bluish skin. Many chronic heart and lung conditions can put you at risk for hypoxia. Hypoxia can be life-threatening. If you are experiencing symptoms of hypoxia, call 911 or go to the nearest ER. Overview If you are experiencing any symptoms of hypoxia, especially if you have an underlying heart or lung condition, call your healthcare provider or go to the nearest ER. What is hypoxia? Hypoxia is when the tissues of your body don’t have enough oxygen. When you breathe, you take oxygen into your You can think of oxygen as billions of passengers flying into the airport (your lungs). They get picked up at the gate and get on the highway (blood vessels) to be taken to their destination (your tissues). As the oxygen gets dropped off, it makes room for a different passenger to be picked up: carbon dioxide. Carbon dioxide is a waste product, which is then taken back to your lungs and exits your body when you breathe out. If not enough oxygen gets through at any place on the journey, it can lead to hypoxia. Airflow and blood flow are both important to the process. This is why lung disease and heart disease both increase your risk of hypoxia. Someone who experiences hypoxia is called hypoxic. Hypoxia vs. hypoxemia: What’s the difference? You may hear the words hypoxia and hypoxemia used interchangeably, but they aren’t the same. The name...
