An oxygen level of 88% is dangerously low (hypoxemia) and requires immediate medical attention: call emergency services (like 911) or go to the nearest emergency room right away, especially if you have symptoms like shortness of breath, confusion, or dizziness. While some with lung conditions might have levels between 88-92%, 88% generally indicates a serious issue needing urgent assessment for the root cause, like pneumonia, COPD, or heart problems, and potential treatment like supplemental oxygen.
If it's at 88% or lower, get to the nearest emergency room as soon as possible. If you have a chronic lung condition, such as COPD or asthma, you'll likely need to see your healthcare provider regularly to make sure your treatment is working.

Vital Signs
It may be helpful to have a baseline as some patients living with lung disease can tolerate low oxygen levels for months and months. Generally, if the oxygen level is 79% or lower, they will likely die in the next 24 hours.
If your blood oxygen level is 88% or lower, call 911 or go to your nearest Emergency Department. If you need to go to the hospital, you will likely receive a blood test called an arterial blood gas, which can make sure your blood oxygen level is accurate so you can get treatment as needed.
Blood oxygen saturation <90% was independently associated with 30-day mortality or hospitalization (adjusted odds ratio (OR), 1.7; 95% confidence interval (CI) 1.1-2.8; P = . 032).
If the oxygen saturation drops below 85%, the severe lack of oxygen affects the brain. The person may experience vision changes and lose consciousness.
The following symptoms are often a sign that the person is about to die:
Healthy pulse oximeter values often range from 95% to 100%. Values under 90% are considered low. Often, hypoxemia treatment involves receiving extra oxygen. This treatment is called supplemental oxygen or oxygen therapy.
In hypoxic hypoxia 95–100% saturation is considered normal; 91–94% is considered mild and 86–90% moderate. Anything below 86% is considered severe. Cerebral hypoxia refers to oxygen levels in brain tissue, not blood.
Low oxygen concentrations can include giddiness, mental confusion, loss of judgment, loss of coordination, weakness, nausea, fainting, loss of consciousness, and death. 20.9 percent: Normal atmospheric oxygen content.
When you feel short of breath, pursed-lip breathing helps get more oxygen into your lungs and calms you down, so you can better control your breath. To practice pursed-lip breathing, sit down in a chair and relax your neck and shoulder muscles. Breathe in slowly through your nose, making sure to keep your mouth closed.
Stay hydrated:
One must drink filtered water to get the full benefits of oxygenation. So ensure that you make a habit of drinking water throughout the day. Also remember that caffeinated beverages, alcohol, and food with high sodium can dehydrate the body, so it's best to avoid consuming them.
Open windows or get outside to breathe fresh air.
Something as simple as opening your windows or going for a short walk increases the amount of oxygen that your body brings in, which increases overall blood oxygen level. It also has benefits like improved digestion and more energy.
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.
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.
If your blood oxygen level is low, you will benefit from oxygen therapy which should bring your blood oxygen level up to the normal range. If your blood oxygen level is normal, you will probably not benefit from oxygen therapy, even if you feel a little breathless.
Low oxygen levels can make you feel tired and mentally foggy. If you are experiencing chronic fatigue, headaches, dizziness or confusion, it may be due to low oxygen levels. Oxygen therapy can help improve energy and cognitive abilities by ensuring the brain and muscles get enough oxygen.
Consume dark leafy greens: Leafy greens such as kale and spinach increase blood oxygen. They contain nitrogen, which “plays a major role in delivering oxygen throughout the body.” Incorporate iron-rich foods: Foods like white beans, tofu, and dark chocolate contain iron, an “essential element for blood production.”
Some common symptoms of many types of organ failure include:
Breathing may become irregular with periods of no breathing or apnea lasting 20-30 seconds. Your loved one may seem to be working hard to breathe -- even making a moaning sound. The moaning sound is just the sound of air passing over very relaxed vocal cords. This indicates that the dying process is coming to an end.
Key signs 2 weeks before death at the end-of-life stages timeline: Extreme fatigue and increased sleep. A marked decrease in appetite and fluid intake. Irregular breathing patterns (Cheyne-Stokes breathing)
Some common causes of hypoxemia include:
Oxygen Therapy: Supplemental oxygen may be provided to alleviate shortness of breath and improve oxygenation. However, it's essential to monitor oxygen levels carefully to avoid potential complications. In most cases using nasal cannula oxygen is enough to provide a comfortable flow of oxygen to the dying patient.
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.
