Do you still breathe under anesthesia?

Yes, you breathe under anesthesia, but your natural breathing is usually assisted or fully controlled by a machine through a breathing tube (intubation) because the drugs relax your respiratory muscles, preventing you from breathing adequately on your own. An anesthesiologist closely monitors and manages your airway, ensuring a continuous oxygen supply and safe gas exchange throughout the procedure.

Why do people stop breathing under anesthesia?

People stop breathing under anesthesia because the medications relax all muscles, including those controlling breathing, and suppress the brain's respiratory centers, making the lungs unable to function independently; therefore, patients are connected to a ventilator to breathe for them, but risks like airway blockage from muscle relaxation or pre-existing conditions (like sleep apnea) increase the danger, requiring close monitoring by anesthesiologists.
 

Can you breathe by yourself under general anesthesia?

No, under general anesthesia, your muscles, including those for breathing, are relaxed or temporarily paralyzed, so you generally cannot breathe effectively on your own; an anesthesiologist assists or controls your breathing with devices like breathing tubes and ventilators to ensure oxygenation. While some situations allow for spontaneous breathing support, the primary goal is airway control, usually via an endotracheal tube or laryngeal mask airway (LMA) connected to a ventilator. 

What does it feel like to breathe in anesthesia?

General anesthesia may also be given in a gaseous form that you inhale via mask. This may cause a buzzing sensation and dizziness as the gas enters your bloodstream through the pulmonary capillaries (tiny blood vessels in the lungs) and acts on centers within the brain to produce a loss of consciousness.

How long will I be asleep under anesthesia?

After general anesthesia, you typically start waking up within minutes, but it takes 1-2 hours to become fully alert, feeling groggy and drowsy as the drugs wear off, with effects lingering for about 24 hours before you can resume normal activities like driving, requiring someone to drive you home. The exact time varies by procedure length, medications, age, and health, with sedation taking less time than deep general anesthesia. 

3 things you DON'T KNOW happen to YOUR BODY under anesthesia (and HACKS TO FIX in 2023!)

How do people breathe during anesthesia?

Under anesthesia, your breathing is managed by the anesthesia team, often using a breathing tube (endotracheal tube) placed in your windpipe to deliver oxygen and anesthetic gases, or sometimes a mask, ensuring you get enough oxygen and protecting your lungs, while a ventilator helps breathe for you, as muscles relax and spontaneous breathing can become shallow or stop.
 

Does your heart still beat under anesthesia?

The drugs used in general anesthesia do not directly affect the heart. Instead, they slow down the body's metabolism, which can reduce the amount of oxygen being delivered to the heart. This can cause the heart rate to slow down, but it is not likely to stop completely.

How do anesthesiologists know you're asleep?

Anesthesiologists know you're "asleep" (unconscious) by combining continuous monitoring of vital signs (heart rate, blood pressure, oxygen) with specialized brain activity monitors (like EEG/BIS monitors) that track electrical signals, ensuring brain activity aligns with unconsciousness, and checking for lack of movement or response, especially when muscle relaxants are used, as general anesthesia isn't natural sleep but a drug-induced coma. They use these tools to confirm you're not experiencing awareness during surgery. 

Do you breathe through your nose or mouth during surgery?

Once the area is numb, the anaesthetist will pass a small flexible tube attached to a camera through your mouth or nose. This guides the breathing tube into your trachea. Once the breathing tube is safely in place, your anaesthetist will start the general anaesthetic and you will become unconscious.

Are you paralyzed under general anesthesia?

Yes, general anesthesia often paralyzes you, especially the muscles needed for breathing, which is why a ventilator is required to breathe for you during surgery; this muscle relaxation (immobility) is a key part of anesthesia, achieved with neuromuscular blocking agents (paralytics), alongside unconsciousness, pain relief, and memory loss, allowing surgeons to operate safely.
 

Do they put a breathing tube in during surgery?

Yes, for most surgeries requiring general anesthesia, an anesthesiologist places a breathing tube (endotracheal tube) into your windpipe to help you breathe, deliver oxygen, and protect your lungs while you're unconscious. This tube, connected to a ventilator, ensures proper breathing and oxygenation, especially since anesthesia affects your natural respiratory drive, and is removed as you wake up, though sometimes kept in longer for critical care.
 

Do you snore under general anesthesia?

Yes, you can snore under general anesthesia because the muscles in your throat relax, causing partial airway obstruction, similar to regular sleep apnea; anesthesiologists actively manage this by using airways or breathing tubes to keep your breathing open and oxygen flowing, preventing severe blockage.
 

Why can't you breathe during general anesthesia?

During a general anaesthetic, the muscles in your body relax, including those around your throat and chest. This can lead to your airway becoming blocked or your breathing becoming restricted.

What does waking up from anesthesia feel like?

Waking up from anesthesia often feels groggy, confused, and sleepy, with common temporary side effects like chills, nausea, dry mouth, sore throat (from a breathing tube), and itching. You might feel disoriented, emotional, or even experience temporary memory issues, but these usually pass as the medication wears off, with nurses providing support and pain relief. 

How long does it take to recover from 30 minutes of anesthesia?

Answer: Most people are awake in the recovery room immediately after an operation but remain groggy for a few hours afterward. Your body will take up to a week to completely eliminate the medicines from your system but most people will not notice much effect after about 24 hours.

How fast do you fall asleep under anesthesia?

Anesthesia works very fast, usually putting you to sleep within 30 to 60 seconds when given intravenously (IV) for general anesthesia, with powerful drugs like propofol crossing the blood-brain barrier quickly. Inhalation anesthesia also takes effect rapidly as you breathe it in, though it can take slightly longer than an IV, while sedation for lighter procedures might take a few minutes to fully kick in, depending on the specific medication.
 

What is the 2 4 6 rule for anesthesia?

The 2-4-6 rule for anesthesia is a guideline for preoperative fasting, indicating how long patients should abstain from food and drink before surgery to prevent aspiration (inhaling stomach contents): 2 hours for clear liquids, 4 hours for breast milk, and 6 hours for formula or light meals, with heavier meals requiring longer (often 8+). This evidence-based rule, established by the American Society of Anesthesiologists (ASA), replaces older "NPO after midnight" mandates, allowing for shorter, safer fasting times for most healthy patients. 

Who cannot go under anesthesia?

In addition to the elderly, people who have conditions such as heart disease (especially congestive heart failure), Parkinson's disease, or Alzheimer's disease, or who have had a stroke before are also more at risk. It's important to tell the anesthesiologist if you have any of these conditions.

How does anesthesia put you to sleep so fast?

Anesthesia works so fast by delivering powerful drugs directly into your bloodstream (IV) or lungs (gas), which rapidly travel to the brain to block nerve signals, essentially hijacking the brain's natural sleep circuits and shutting down communication between brain regions, leading to quick unconsciousness, memory loss, and pain blocking, notes BrainFacts. Agents like Propofol quickly activate inhibitory neurons (GABA receptors), overwhelming the brain's excitatory signals, creating a state similar to a coma rather than natural sleep, allowing surgeons to work safely. 

Why do people have heart attacks under anesthesia?

Common causes include hypoxia, hypovolemia, and increased vagal activity due to medications routinely used during general anesthesia or surgical stimulation. The patient in this report was taking 2 medications, propranolol and guanfacine, which likely contributed to the bradycardia and eventual cardiac arrest.

What happens if you don't wake up from anesthesia?

If you don't wake up from anesthesia as expected, it's usually a delayed emergence, often due to lingering medication, but can signal serious issues like metabolic problems or neurological events, requiring close monitoring and supportive care, sometimes with reversal drugs, to ensure breathing and vital signs remain stable until consciousness returns, which is a rare but serious situation. 

Why do they put a tube down your throat during surgery?

They put a tube down your throat during surgery to create a secure airway, ensuring you get enough oxygen and anesthetic gases while protecting your lungs from fluids, because general anesthesia suppresses natural breathing. This endotracheal tube (ET tube) connects to a ventilator, allowing controlled breathing and preventing airway obstruction, with the tube usually removed as you wake up.
 

What is going under anesthesia like?

Going under anesthesia feels like drifting into a deep, dreamless sleep, with a quick transition from feeling alert to total unconsciousness, no pain, and no memory of the surgery; you'll likely feel groggy, disoriented, or chilly upon waking as the effects wear off, with common temporary side effects like nausea or confusion. A dedicated medical team monitors your vitals throughout, ensuring your safety while you're "asleep," but experiencing no sensation.
 

How many times is it safe to go under anesthesia?

In general, anesthesia is considered safe, and most people can undergo multiple procedures with anesthesia without any long-term adverse effects. However, each time you undergo anesthesia, there is a small risk of side effects or complications such as nausea, vomiting, sore throat, headache, or confusion.

What if I stop breathing under anesthesia?

If you stop breathing during anesthesia (apnea), your anesthesiologist immediately intervenes with a breathing tube (endotracheal tube) or mask to manually ventilate you with oxygen, preventing serious brain damage (hypoxia/anoxia) from oxygen deprivation, which can cause cognitive issues, memory loss, or worse; this is usually managed quickly with monitoring and interventions like ventilators or reversal agents, but serious outcomes can happen if it's not handled fast enough, especially in high-risk patients like those with sleep apnea.
