Proning is when healthcare providers move someone from lying on their back (supine position) to lying on their front, face-down (prone position). Healthcare providers use it to help people with certain serious respiratory conditions get more oxygen.
Healthcare providers usually prone people who are on mechanical ventilation (prone ventilation). Many providers work together to move them into the prone position.
More people are aware of proning now because of its use to treat people with COVID-19, but it’s not a new thing. Providers have used it for several decades. Studies suggest it can significantly reduce mortality (death) rates in certain people with severe respiratory illness on mechanical ventilation if done early.
Providers use proning to help get more oxygen to people with severe respiratory conditions who aren’t getting enough (hypoxia). Most commonly, it’s used in acute respiratory distress syndrome (ARDS). ARDS causes fluid to collect in your alveoli, the small air sacs in your lungs. This makes it hard to breathe. ARDS is a serious complication of many respiratory illnesses, including COVID-19 and pneumonia.

Why does proning improve oxygen levels (oxygenation)?
The reason proning works is largely because our bodies aren’t symmetrical. Proning does two things to get more oxygen to your body. It:
Decreases the amount of weight and compression on your lungs, allowing more air to get to your alveoli (improved ventilation).
Improves your lung efficiency by getting oxygen to the parts of your lungs that get the most blood flow (improved gas exchange).
Improved ventilation
Because of the way human bodies are shaped, you have more lung tissue toward your back than your chest. When you’re lying on your back, excess fluid presses on your alveoli, preventing them from completely filling with air. Your heart and abdominal organs at the front of your body also put pressure on your lungs when you’re lying on your back.
When you’re lying on your belly in the prone position, the weight of your heart and abdominal organs rests on your chest instead of your lungs. Fluid in your lungs compresses a smaller area of lung tissue. This leaves the larger area of your lungs at your back available to hold air.
Improved gas exchange
During ARDS, there’s a mismatch between the amount of oxygen that’s getting into your lungs (ventilation) and the amount that’s getting into your bloodstream (perfusion). Your blood carries oxygen from your lungs to the rest of your body. Ideally, you’d have the same amount of ventilation and perfusion.
Meanwhile, the back part of your lungs gets better blood flow than the front, no matter what position you’re in. When you’re in the prone position, not only are you opening up more alveoli so you can get more oxygen to your lungs, you’re getting the oxygen to the part of your lungs that has better blood flow. This makes breathing more efficient, with ventilation and perfusion more closely matched.
Proning is a technique used by healthcare providers to move someone into the prone position
prone position
Prone position (/proʊn/) is a body position in which the person lies flat with the chest down and the back up. In anatomical terms of location, the dorsal side is up, and the ventral side is down.
(face-down on their belly). This can increase your oxygen levels if they're too low due to severe respiratory illness. It's most commonly used in people who are on a ventilator.
Facial edema and ocular complications have also been reported in patients who have been put in prone position for surgical procedures and/or respiratory failure. Vision loss can occur as a result of increased orbital pressure or direct trauma to underlying structures.
Placing the patient in the prone position results in more uniform alveolar architecture and perfusion, thus reducing regional V/Q mismatch and improving oxygenation. The consequent improvement in oxygenation leads to further improvement of the V/Q mismatch and is associated with reduced mortality [1,2].
The purpose of proning is to allow better distribution and volume of air in the lungs. When the patient is proned, the position facilitates better ventilation of the posterior lung regions. HCGH had a manual process, but with the number of patients we were proning, it required a team.
Furthermore, numerous lines of evidence have confirmed that prone positioning could prevent lung injuries caused by ventilators (6-7). In supine position, the heart and its adjacent parts likely compress the central posterior parts of the lung.
Surgical staff should consider risks and complications associated with the prone position such as increased intra-abdominal pressure, increased bleeding, abdominal compartment syndrome, limb compartment syndrome, nerve and pressure injuries, and cardiovascular compromise, among others.
Providers can see improvement in your oxygen levels in as little as one hour, but they'll usually keep you prone for 12 to 18 hours to see if you improve. If you do, they'll keep you in the prone position for at least 16 hours per session and return you to a supine position in between.
Contraindications to prone positioning include the presence of spinal instability, unstable fractures, an open chest or an unstable chest wall, an open abdomen, elevated intracranial pressure, acute bleeding, and severe hemodynamic instability.
While it helps with snoring it is not advised by professionals. The spine is the least supported while sleeping on the stomach. Additionally, sleeping in a prone position increases the pressure on the spinal tissues which could lead to pain upon waking.
Prone positioning is generally used for patients who require a ventilator (breathing machine). Prone positioning may be beneficial for several reasons: (1) In the supine position, the lungs are compressed by the heart and abdominal organs.
If you have a long-term (chronic) lung problem associated with excessive mucus, or you have increased mucus from an infection, lying with your chest lower than your belly (abdomen) can help loosen and drain extra mucus from your lungs.
Lying prone can also help your cough to be more effective. This helps with clearing out any secretions that are in your chest. Current, available evidence suggests that lying prone must be considered early in the treatment of acute lung conditions for the best outcomes.
Lie on your side with a pillow between your legs and your head elevated with pillows. Keep your back straight. Lie on your back with your head elevated and your knees bent, with a pillow under your knees.
Inflammation in the lungs and respiratory tract can reduce the flow of oxygenated blood throughout the body, causing a patient to gasp for air. Normal oxygen saturation levels range between 94%-99%. When SPo2 levels fall below 93% it is a sign that oxygen therapy is required.
Ventilation in the prone position (PP) has been used for decades in patients with acute respiratory distress syndrome (ARDS) and is associated with a reduction in mortality rate. Its application has been extended to patients with SARS-Cov-2 pneumonia and is recommended by the main international organizations.
Placing patients in a prone (face-down) position is a technique that helps improve breathing for patients with pulmonary distress and/or complications. The resulting inflammation and fluid buildup in the lungs can cause great difficulty breathing, requiring the use of a ventilator (mechanical breathing machine).
