Hospitals and surgical facilities typically advise patients to remove nail polish before surgery. This is because a device called a pulse oximeter is clipped onto the fingertip to monitor oxygen levels in the blood. The oximeter works by sending light through the finger and analyzing the amount that passes through. Nail polish, including artificial nails and nail extensions, can prevent the pulse oximeter from accurately detecting oxygen levels and may also chip or peel, leading to potential contamination of sterile surfaces.

What You'll Learn
Hospitals advise removing nail polish before surgery
Hospitals advise patients to remove nail polish before surgery for several reasons. Firstly, it is important for monitoring a patient's health during surgery. A device called a pulse oximeter is often used to monitor a patient's blood oxygen levels during surgery. This device is typically attached to the fingertip and works by passing red light through the tissue to measure oxygen levels in the blood. Nail polish, including acrylic nails, shellac, and gel nail polish, can interfere with the accuracy of the pulse oximeter, reducing its effectiveness in detecting oxygen levels.
The nail bed is one of the best places to detect cyanosis, a bluish discolouration of the skin and tissues caused by low oxygen levels in the blood. Nail polish can conceal the presence of cyanosis, hindering the early detection of hypoxemia, or low blood oxygen levels. Therefore, removing nail polish is crucial for ensuring the safety of the patient during surgery.
Additionally, surgical environments require sterility to minimize the risk of infection. Nail polish can chip or peel, potentially contaminating sterile surfaces. Long nails, often associated with nail polish, may also harbour bacteria and germs, increasing the risk of infection. Removing nail polish and maintaining short, natural nails help ensure a clean and sterile environment during surgery.
In certain cases, some surgical facilities may permit the use of specific types of nail polish, such as clear, liquid-fast-drying, and chip-resistant formulas. However, it is always advisable to consult with the surgical team beforehand to confirm their requirements and any necessary precautions.
It is recommended to remove nail polish the night before or the morning of the surgery. If a patient forgets to do so, they should inform the surgical team, who may offer solutions such as removing the nail polish or using alternative monitoring methods.

Pulse oximeters monitor blood oxygen levels
Patients are often advised to remove nail polish before surgery or a local anesthetic. This is because pulse oximeters are vital medical devices used to monitor blood oxygen levels in patients. They are small, portable devices that measure oxygen saturation levels in arterial blood non-invasively. Pulse oximeters are one of the most important monitoring devices that help make modern anesthesia so safe.
Pulse oximeters work by emitting light into a body part, usually a finger, earlobe, or toe, and measuring the amount of light that returns based on the absorption of red and infrared light by the blood. Oxygenated blood absorbs light differently than deoxygenated blood, allowing the oximeter to calculate the percentage of oxygen saturation. Most healthy individuals will have an oxygen saturation level of 95% to 100%. If levels fall below this range, it could indicate a respiratory or circulatory issue that requires medical attention.
The accuracy of a pulse oximeter reading is critical in diagnosing and managing patients with respiratory or cardiovascular diseases. Inaccurate readings can delay urgent medical attention and lead to inappropriate interventions and incorrect therapeutic decisions. When choosing a pulse oximeter, it is important to consider accuracy, reliability, and ease of use. Factors such as patient movement, skin color, and nail polish can affect the accuracy of the reading.
Pulse oximeters are widely used in hospitals, emergency departments, and operating rooms, and by patients at home. They are particularly beneficial for individuals with chronic lung or heart conditions, such as COPD, asthma, or sleep apnea, as they can track their oxygen saturation levels regularly and ensure their body is receiving enough oxygen. Pulse oximeters are also useful for athletes, especially those engaged in high-altitude sports, as they can monitor how their bodies adapt to reduced oxygen availability.

Nail polish affects pulse oximeter readings
Hospitals and offices typically advise patients to remove nail polish before surgery. This is because nail polish can interfere with pulse oximeters, which are important monitoring devices that measure the oxygenation of a patient's haemoglobin. A sensor is placed on the fingertip and measures the level of oxygen in the blood by passing red light through the tissue.
Several studies have been conducted to determine the effect of nail polish on pulse oximetry readings. One blind study examined the effect of nail polish colour on oxygen saturation measurements by applying blue, green, purple, black, and red nail polish to the fingernails of 14 adult volunteers. The study found that black, blue, and green nail polish significantly lowered oximeter readings, with blue and green producing greater decreases than purple and red, and black producing an intermediate decrease.
Another study evaluated the accuracy and precision of pulse oximetry readings on gel manicures using two different oximeters. This study found that certain colours, such as black, purple, navy blue, and green, affected the precision of the readings more than other colours.
While the impact of nail polish on pulse oximetry readings is still controversial, with some studies showing no clinically significant changes in healthy individuals, it is generally recommended to remove nail polish before pulse oximetry monitoring to ensure accurate readings. This is especially important in clinical settings, as accurate oxygen saturation measurements are crucial for patient care.

Sterile surgical environments are crucial
Monitoring devices such as the pulse oximeter, which measures blood oxygen levels, are crucial for patient safety during surgery. The oximeter is typically attached to the fingertip, where it can accurately monitor the oxygenation of a patient's haemoglobin by passing red light through the tissue. However, nail polish can interfere with the oximeter's ability to detect oxygen levels, affecting the results. The nail bed is one of the best places to detect cyanosis, a bluish discolouration caused by low oxygen levels. Nail polish can conceal this condition, preventing the timely detection of hypoxemia, or low blood oxygen levels.
To ensure accurate monitoring and maintain a sterile environment, hospitals and surgical facilities advise patients to remove nail polish, acrylic nails, shellac polish, and similar products before surgery. In some cases, surgical teams may offer to remove the nail polish upon arrival or suggest alternative monitoring sites, such as attaching the oximeter to the earlobe instead of the fingertip.
While toenail polish is generally allowed as it does not interfere with surgical monitoring, it is always best to consult with the surgeon or surgical facility to confirm their specific requirements and guidelines. Adhering to these instructions is vital to ensuring a sterile surgical environment and the safety of the patient.

Toenail polish is generally permitted
It is important to note that while toenail polish may be permitted, other types of nail polish and artificial nails are usually requested to be removed prior to surgery. This includes acrylic nails, shellac polish, gel nail polish, and solar nails. The reason for this request is primarily related to patient safety and the accuracy of monitoring devices.
The pulse oximeter, a vital monitoring device used during surgery, measures oxygen levels in the blood by sending light through the fingertip or earlobe. Nail polish, especially dark or richly pigmented colors, can interfere with the accuracy of this device by reducing the light that passes through. Additionally, long nails associated with nail polish can hold bacteria and germs, increasing the risk of infection.
To ensure patient safety and accurate monitoring, it is generally recommended to remove nail polish and artificial nails before surgery. However, as mentioned earlier, toenail polish is often permitted as it does not typically interfere with the pulse oximeter or other monitoring devices used during surgery. It is always advisable to consult with your surgeon to confirm their specific requirements and ensure you are adequately prepared for the procedure.
In conclusion, toenail polish is generally permitted in surgical settings, but it is important to confirm with your surgeon beforehand. The main concerns related to nail polish during surgery are the accuracy of monitoring devices and maintaining a sterile environment to ensure patient safety. By following the instructions provided by your surgeon, you can ensure a safe and successful procedure.
