Dangerously low breathing, called bradypnea, is an abnormally slow respiratory rate (under 12 breaths/min in adults) that prevents enough oxygen from entering the blood and carbon dioxide from leaving, leading to respiratory depression, a severe state often caused by drug overdose (opioids, sedatives), head injury, or serious illness, characterized by confusion, extreme drowsiness, and bluish skin, requiring immediate emergency care.
Bradypnea: An abnormally slow respiratory rate, typically fewer than 12 breaths/min in adults. Common causes include sedative or opioid use, hypothyroidism, alcohol intoxication, and traumatic brain injury. Tachypnea: An abnormally rapid respiratory rate, greater than 20 breaths/min in adults.
The most plausible explanation for the increase in respiratory rate is that prednisone may pass through the blood-brain barrier and stimulate the breathing centre. Another hypothesis was that the shortness of breath was due to hyperventilation induced by psychological effects.
Shortness of breath (SOB) is serious and requires immediate emergency care if it's sudden, severe, or accompanied by chest pain, dizziness, fainting, blue lips/nails, confusion, or inability to speak in full sentences; it can signal heart or lung emergencies like heart attack, pulmonary embolism, or severe asthma, so seek help if you have trouble breathing at rest, feel sick, cough up blood, or experience worsening chronic SOB.
Bradypnea is a slower-than-usual respiration rate. The average adult breathes 12–20 times per minute, while children typically have higher respiration rates. Conditions such as hypothyroidism, toxin exposure, or brain injuries can cause bradypnea. Symptoms may include confusion, headaches, or weakness.
Respiratory Distress FAQs
In addition to the signs & symptoms seen in adults, children may have the following signs and symptoms: Nasal flaring (widening of the nostrils when breathing in) More pronounced use of the chest and neck muscles to breathe (muscles pull in around the collarbone and ribs) Grunting.
If left untreated, bradypnea can lead to serious complications, including: Oxygen deprivation and subsequent organ damage. Increased risk of heart failure or stroke. Difficulty performing physical activities due to fatigue and lack of oxygen.
Learning the signs of respiratory distress
There are many reasons you may need supplemental oxygen. One is if you are not getting enough oxygen (this is called hypoxia) after a bad case of pneumonia put you in the hospital. Symptoms of hypoxia include headaches, weakness, shortness of breath, fainting, chest pain, muscle pain and lightheadedness.
you have severe difficulty breathing – you're gasping, choking or not able to get words out. your chest feels tight or heavy. you have pain that spreads to your arms, back, neck and jaw. your lips or skin are turning very pale, blue or grey – on brown or black skin, this may be easier to see on the palms of the hands.
Prednisolone is a glucocorticoid, also known as a corticosteroid, used to reduce inflammation, particularly in the lungs, to prevent lung fibrosis. It is available in both oral and intravenous forms. Oral prednisolone is typically taken once daily in the morning and comes in 1mg, 5mg, and 25mg tablets.
Prednisolone is a corticosteroid (cortisone-like medicine or steroid). It works on the immune system to help relieve swelling, redness, itching, and allergic reactions.
Common side effects
It may seem erratic, with moments of rapid breaths followed by periods of slowed or irregular breathing. This pattern often indicates the body's diminishing ability to regulate breathing. Some providers may call this form of breathing mandibular breathing or guppy breathing as it appears like a fish out of water.
Bradypnea is an abnormally slow breathing rate. It's a symptom of an underlying health condition, which may include hypothyroidism, head injuries or opioid or heavy alcohol use. Associated symptoms may include dizziness, confusion and feeling tired.
Adults have a normal breathing rate of 12 to 25 breaths per minute at rest (no activity). Transient tachypnea in a newborn occurs if your baby has a respiratory rate of more than 60 breaths per minute. In adults, you could experience tachypnea if you take more than 25 breaths per minute at rest.
A low oxygen level in the blood can cause shortness of breath and air hunger (the feeling that you can't breathe in enough air). Your skin, lips, and fingernails may also have a bluish color.
Patients with hypoxemia (blood oxygen saturation <90%) are usually hospitalized, although validated criteria (eg, the Pneumonia Severity Index [PSI]) suggest outpatient treatment is safe.
Silent hypoxia (also known as happy hypoxia) is generalised hypoxia that does not coincide with shortness of breath. This presentation is known to be a complication of COVID-19, and is also known in walking pneumonia, altitude sickness, and rebreather diving.
Acute respiratory failure can be a life-threatening emergency. Low oxygen levels in your blood can cause: Difficulty with routine activities such as dressing, taking a shower, and climbing stairs, due to extreme tiredness. Shortness of breath or feeling like you cannot get enough air (called air hunger)
Healthcare providers sometimes classify ARDS into three stages: exudative, proliferative and fibrotic. This classification mainly describes the level of inflammation and fluid buildup, and the subsequent repair process that your lungs go through to heal.
In medical terms, wet lungs are also called pneumonia which is an infection that causes inflammation of the alveoli or air sacs in one or both lungs. This causes breathing problems because the alveoli are filled with fluid.
As the brain dies, the respiratory system often responds with periods of no breathing (apnea), where the time between breaths becomes longer and longer. The respiration rate may decrease below 8 breaths per minute.
Electrolyte imbalances: Abnormal levels of electrolytes, such as potassium or sodium, can affect nerve function and lead to bradypnea. Cardiac issues: Certain heart conditions, including heart block or myocardial infarction, can disrupt the standard electrical signals regulating heart rate and breathing.
Diaphragmatic breathing involves breathing in slowly through the nose and then out through the mouth using the diaphragm (the thin muscle that separates the chest from the abdomen) and abdominal muscles.
