What Is a Good Oxygen Rate by Age? Topic Guide

There are five main types of headaches including migraines, cluster headaches, tension headaches, sinus headaches, and mixed headaches. Knowing what kind of headache you have is the first step in identifying how to get rid of a headache. There are several treatments for headaches depending on the type of headache you have and your headache triggers. The worst headache of your life could signal a medical emergency and you should seek immediate evaluation.

Acute respiratory distress syndrome (ARDS) is a severe lung condition caused by trauma, sepsis, pancreatitis, aspiration, drug overdose, and massive blood transfusion. Symptoms include: shortness of breath, anxiety, agitation, and fever. Treatment is generally ICU care in a hospital with antibiotics and oxygen treatments. There is no cure for ARDS.

Anemia can be caused by many conditions and diseases such as iron deficiency, poor diet and nutrition, cancers, bone marrow problems, and more. Symptoms of anemia depend upon the cause, and progression of the disease. Treatment depends upon the cause of anemia.

Asthma is a disease that affects the breathing passages of the lungs (bronchioles). Asthma may be caused by genes and environmental factors. Asthma causes wheezing, shortness of breath, and other symptoms. Treatment includes avoidance of triggers and medications to control and prevent symptoms.

Asthma is a disease marked by inflammation of the airways that cause difficulty breathing. Ther are millions who suffer from this chronic disease, and this article covers some of their frequently asked questions (FAQs).

Children account for 47.8% of asthma-related visits to the emergency department. Asthma symptoms include wheezing, coughing, and chest tightness. Treatment focuses on managing the child's symptoms and preventing future asthma attacks with medicines that provide the best results with the fewest side effects.

Asthma is a disease that affects the breathing passages of the lungs (bronchi and bronchioles). Asthma is caused by chronic (ongoing, long-term) inflammation of these passages. Asthma medications include corticosteroid inhalers, oral and intravenous corticosteroids, leukotriene inhibitors, beta-agonists, anticholinergic inhalers, methylxanthines, mast cell inhibitors, and monoclonal antibodies.

Bacterial pneumonia is an infection of the lungs. People with pneumonia usually experience coughing, fever, shortness of breath, and chest pain. Pneumonia is a leading cause of death from infection.

The cause of MIS-C (multisystem inflammatory syndrome in children) is unknown but of the children who have developed MIS-C, many have had COVID-19 or been exposed to someone who has.

About 80 percent of the people who get COVID-19 have relatively mild respiratory symptoms that don’t require hospitalization. For these people, rest and over-the-counter pain and fever medications can help treat coronavirus symptoms.

Chronic obstructive pulmonary disease (COPD) is a lung condition in which there is a long-lasting obstruction of the airways, and occurs with emphysema, chronic bronchitis, and/or asthma. Causes of COPD include cigarette smoking, exposure to secondhand smoke and environmental tobacco smoke, Alpha 1-antitrypsin deficiency, airway hyper-responsiveness, and air pollution. Symptoms of COPD include a productive cough and acute chest illness, shortness of breath, wheezing, heart failure, cyanosis, and weight loss. Treatment of COPD includes medications, oxygen therapy, surgery, and lung transplant.

A collapsed lung or pneumothorax is a condition in which the space between the wall of the chest cavity, the as a result all or a portion of the lung collapses. Types of pneumothorax include tension and simple. Causes of pneumothorax include spontaneous, traumatic, disease and related. Pneumothorax is a life-threatening emergency. Medical care should be sought immediately.

Coronaviruses are very common and typical cause cold-like symptoms. There are seven coronaviruses that infect humans, with SARS, MERS, and COVID-19 being the most notable of the seven. However, COVID-19 (Wuhan coronavirus, 2019 novel coronavirus, or 2019-nCoV) appears to be more contagious than MERS or SARS and appears to not only spread via respiratory secretions, but it may also spread through fecal contamination.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus that causes COVID-19. Reduce your risk of infection with the following tips: wash your hands frequently or use hand sanitizer that contains at least 60% alcohol; avoid touching your face if your hands aren't washed; practice social distancing (maintaining a distance of at least 6 feet).

All currently available vaccines have been found to be safe, effective, and reduce the risk of severe illness and death from COVID-19. Common side effects of COVID-19 vaccines include injection site reactions (pain, tenderness, redness, swelling), fever, chills, fatigue/tiredness, muscle aches or pains, headaches, nausea, and vomiting. Severe allergic reactions (anaphylaxis) are rare.

What causes headaches? Even when mild, headaches can be a cause for concern. Learn about potential causes, types, home remedies, and treatment.

Migraine is one of over 150 types of headaches. Other common types of headaches include tension, cluster, sinus, and hormonal. Pain is the most common symptom of all headaches, and the severity of the pain depends upon the type of headache. Migraine pain is severe, pulsating, and is located only on one side of the head. Other symptoms and signs of a migraine headache are eye pain, sensitivity to light, sounds, or smells, nausea, and vomiting. Migraine is more common in women, and may increase in frequency and severity during menopause.Signs and symptoms of other common types of headaches. Tension headaches: The pain of a tension headache starts at the back of the head and upper neck. The pain is described as a band-like tightness or pressure on both sides of the head that may spread over the entire head. The pain and pressure is felt over the eyebrows, is sporadic, and usually varies in intensity. Tension headaches are not disabling. Cluster headaches come in groups or clusters that are separated by pain free periods of months to years. The episodes of pain last from 30 to 90 minutes, occur around the same time of day, and the pain is excruciating around or behind one eye. Men have cluster headaches more often than women. Sinus headaches are caused by bacteria or viral infection of the sinuses. The infection causes inflammation of the sinuses, which results in pain. The pain and pressure from a sinus headache is felt around the area of the sinuses. Other symptoms are facial tenderness and swelling, nasal congestion, stuffy nose, earache, and jaw pain. Sinus headaches usually are caused by sinusitis or a sinus infection. Hormonal headaches are caused by hormonal fluctuations in the body and can be caused by hormonal birth control, menstruation, pregnancy, perimenopause, and menopause. The pain and symptoms depend upon the cause of the headache. There is no specific test to diagnose migraines. Treatment for a migraine and other types of headaches depend upon the type.REFERENCES: Blanda, M, MD. "Cluster Headache." Medscape. Updated: Apr 26, 2017. Brook I, MD. "Acute Sinuitis." Medscape.

A cough can be voluntary or involuntary, and it is the body’s way to help clear the airways of irritants and to prevent infection. Cough is not a disease in itself, but a symptom of an underlying medical condition. The duration, severity and accompanying symptoms will tell your doctor whether the cough is an indication of a serious condition.

Treatment to relieve tension and migraine headaches includes pain relievers (aspirin, ibuprofen, acetaminophen/Tylenol), medications (triptans, trigger point injections), rest, ice, heat, massage, biofeedback, and others.

Pneumonia is a lung infection that can be caused by various bacteria, viruses, and fungi. Symptoms of pneumonia include cough, fever, and difficulty breathing.

Pneumonia is frequently caused by bacteria and viruses which can be contagious, depending on the pathogen. Pneumonia is a potentially deadly lung condition that can affect one or both lungs and cause cough, fever, and trouble breathing.

A pressure headache (tension headache) is the most common type of headache with symptoms such as pressure or tightness on both sides of the head. Tension headaches can happen randomly (episodic) or chronically. Treatment can include rest, ice, heat, massage, biofeedback, pain relievers, and antidepressant medication.

Walking pneumonia is a mild case of pneumonia, a respiratory infection. Symptoms include productive cough, shortness of breath, chest pain that is worse when inhaling, fever, chills, fatigue, sore throat, weakness, headache, and feeling unwell (malaise).

Pneumonia is a lung infection with symptoms such as cough, fever, and trouble breathing. There are two types of pneumonia vaccines used to protect against pneumonia, although not all types. One pneumonia vaccine (Prevnar 13) has an unknown immunity duration, while the other (Pneumovax 23) lasts from five to 10 years.

COVID-19 (coronavirus disease) can be contagious for weeks or longer, depending on the patient. The time from infection to the start of symptoms (incubation) ranges from four days to two weeks, though patients are contagious before symptoms develop. Follow CDC guidelines for self-quarantining if you have a coronavirus infection.

Each person has their own distinctive heart rate variability (HRV), which cannot be measured against a chart, range, or averages. A person’s HRV can change from day to day and from season to season. A person’s age, gender, and even circadian rhythm can affect HRV.

Masks can be safely worn by all children 2 years of age and older, including most children with special health conditions, with rare exceptions. Children under 2 years should not wear a mask due to the risk of suffocation.

Asthma is a chronic respiratory disease that makes it difficult to breathe and requires treatment, while severe asthma does not respond well to treatment.People with asthma may have symptoms that flare up or worsen, but that does not always indicate severe asthma.

COVID-19, a coronavirus disease not previously identified in humans, is responsible for an outbreak of respiratory illness that has become a global pandemic. Sore throat is one of a number of possible symptoms of the disease, but it isn't as common as fever, cough and shortness of breath -- the three most prevalent COVID-19 symptoms.

In lung cancer, lung cells exhibit abnormal and uncontrolled growth starting the lungs, while asthma is caused by inflammation and/or mucus that decreases or blocks the breathing passages (bronchioles) of the lungs. Asthma is usually an acute problem triggered by many different substances mainly affecting the lungs, while lung cancer is considered, once detected, an ongoing disease that can metastasize (spread) to other organs like the liver, bones or the brain.

Lung cancer occurs when healthy cells in lung tissue become abnormal and then multiply causing cancerous (malignant) tumors in the lung(s). Pneumonia is a bacterial, viral, or rarely, a fungal infection in the lung(s). The most common, similar signs and symptoms of lung cancer and pneumonia are cough, chest pain or discomfort, and shortness of breath. Both lung diseases also can cause signs and symptoms like coughing up blood, wheezing, pleural effusion, and lethargy.

Pulmonary edema is a collection of excess fluid in the lungs. Pulmonary edema is classified as either cardiogenic (caused by heart problems) and non-cardiogenic. The primary symptom of pulmonary edema is shortness of breath. Pulmonary edema can be a life-threatening medical situation. The treatment for pulmonary edema can be ICU care in some cases, and medication in other cases.

Pulmonary edema is an excess collection of watery fluid in the lungs that inhibits lung function. Emphysema is a type of chronic obstructive pulmonary disease (COPD).

There is currently no FDA-approved vaccine to prevent COVID-19, but one is authorized for use under an emergency designation. Pfizer-BioNTech created one in distribution Dec. 2020. As of December 12, 2020, The New York Times Coronavirus Vaccine Tracker listed 58 vaccines in clinical trials on humans, with 15 having reached the final stages of testing. At least 85 preclinical vaccines are under active investigation in animals. Possible rare side effects may include allergic reactions and a facial nerve problem called Bell's palsy, but the connection with the vaccine wasn't clear as of late 2020.

A target heart rate refers to what your heart rate should be while doing exercise, while a resting heart rate is the number of beats per minute (bpm) when at rest. An adult’s target heart rate is calculated based on their maximum heart rate, which is calculated based on a person’s age.

The four main categories of asthma, a chronic respiratory disease that makes it difficult to breathe, are intermittent, mild persistent, moderate persistent, and severe persistent.

A type of pneumonia called lobar pneumonia has four stages of development and resolution. Pneumonia is an infection of the lungs that causes cough, fever, and trouble breathing. It can cause serious illness in young children, people over age 65, and people with other health problems. Pneumonia may affect one or both lungs.

There are four stages of COPD (chronic obstructive pulmonary disease), which are determined by the total volume of air that a person can exhale and the amount of air a person can exhale in the first second of a hard exhale, which are measured in a breathing test called spirometry.

The Delta variant of COVID-19 is a newer strain of the virus that appears to be more contagious than other variants. The COVID-19 Delta variant may cause symptoms such as headache, sore throat, runny nose, or fever.

Walking pneumonia is a term often used to describe mild cases of pneumonia, an infection of the respiratory system. Walking pneumonia is usually caused by a type of atypical bacteria called Mycoplasma pneumonia.

There are two main categories of asthma: Allergic, which is triggered by exposure to an allergen, such as pollen or pet dander, and Non-allergic, which is triggered by factors such as stress, illness, extreme weather, irritants in the air, and some medications.

If it is hard to breathe it’s important to see a doctor to diagnose the cause and receive proper treatment. Some causes of breathing difficulty can be life-threatening. Difficulty breathing (dyspnea) may be characterized by shortness of breath, difficulty getting a breath in, or pain when breathing and can be a sign of a serious medical condition.

COPD (chronic obstructive pulmonary disease) is a group of chronic lung diseases that includes emphysema, chronic bronchitis, refractory (non-reversible) asthma, and some forms of bronchiectasis. Symptoms of a COPD exacerbation (flare-up) include tiredness or fatigue, more shortness of breath than usual, more coughing, more wheezing than usual, feeling unwell, feeling as if you have a cold, mucus changes, swollen legs or ankles, trouble sleeping, and others.

A COVID-19 antibody test is a blood test that looks for immune system markers (antibodies) specific to an immune response to the coronavirus. This test can tell you if you have been infected, but there is no way to know just from an antibody test whether you are contagious still or not.

Asthma is a chronic respiratory disease with symptoms such as inflammation and narrowing of the airways, and difficult breathing. The best asthma medication depends on the person's age, symptoms, lung function, risk factors for asthma attacks, patient preference, and certain practical issues (ability to use the medication delivery device or the accessibility of medication).

Of the three COVID-19 vaccines authorized for use in the U.S. that have been shown to be highly effective in reducing the risk of severe disease (including the Delta variant), hospitalization, and death, two of them require boosters. The Modern and Pfizer COVID-19 vaccines involve two shots, while the Johnson & Johnson vaccine involves just one shot.

The main cause of COPD (chronic obstructive pulmonary disease) in the U.S. is smoking tobacco, which accounts for up to 90% percent of all COPD cases. Other causes of and risk factors for COPD include secondhand smoke, air pollutants in the home and workplace, a history of respiratory infections, genetic factors, and poor indoor air quality.

There isn't one drug that's considered the safest asthma medication. Asthma drugs are usually used in combination with others for the best results in controlling symptoms and reducing attacks. The medication choice depends on how the individual responds to them, as well as their underlying conditions.

Signs that a headache is something more serious include major changes in the pattern of your headaches, headaches that get steadily worse, an unusually severe headache (“the worst headache of your life”), head pain that increases with coughing or movement, headache after a blow to the head, headache that interferes with normal daily activities, and others.
