Introduction

Monitoring oxygen saturation is a fundamental aspect of patient care in acute and critical care settings, where timely and accurate assessment of oxygenation status is crucial for optimizing patient outcomes. Oxygen saturation, measured non-invasively using pulse oximetry, provides valuable information about the adequacy of oxygen delivery to tissues and organs. In acute and critical care settings, where patients may be at risk of respiratory compromise or failure, continuous monitoring of oxygen saturation is essential for early detection of hypoxemia and prompt intervention [1].

Acute and critical care settings encompass a diverse range of clinical environments, including emergency departments, intensive care units (ICUs), operating rooms, and post-anesthesia care units (PACUs). Patients admitted to these settings often present with acute respiratory distress, sepsis, trauma, or other life-threatening conditions that require immediate and intensive monitoring and intervention. In such high-stakes environments, optimizing oxygenation and preventing hypoxemia are paramount to patient safety and survival [2].

Pulse oximetry, a non-invasive method for measuring oxygen saturation, has revolutionized the monitoring of oxygenation in acute and critical care settings. By providing continuous, real-time feedback on arterial oxygen saturation (SaO2), pulse oximetry allows healthcare providers to rapidly assess changes in oxygenation status and adjust treatment strategies accordingly. In addition to pulse oximetry, arterial blood gas (ABG) analysis is often performed to confirm oxygen saturation levels and assess acid-base balance in critically ill patients [3].

Despite its widespread use and clinical utility, monitoring oxygen saturation in acute and critical care settings poses several challenges. These challenges include the risk of inaccurate readings due to patient factors (e.g., motion artifact, poor perfusion), device-related issues (e.g., sensor malposition, signal interference), and physiological conditions (e.g., vasoconstriction, hypothermia). Furthermore, patients with severe respiratory compromise or shock may exhibit discordance between oxygen saturation measured by pulse oximetry and actual arterial oxygenation [4].

This review aims to explore the best practices and challenges associated with monitoring oxygen saturation in acute and critical care settings. By examining current guidelines, evidence-based practices, and emerging technologies, we seek to provide insights into optimizing oxygenation monitoring strategies and enhancing patient safety in these high-acuity environments. Additionally, we will discuss strategies for mitigating common challenges and improving the accuracy and reliability of oxygen saturation measurements in acute and critical care settings [5].

Risk factor

Patient Movement and Activity: Patients in acute and critical care settings may be restless, agitated, or unable to cooperate with monitoring procedures due to their condition or sedation. Patient movement can result in motion artifact, leading to inaccurate pulse oximetry readings. Additionally, excessive movement may displace pulse oximeter sensors, compromising signal quality and reliability [6].

Poor Peripheral Perfusion: Conditions such as hypotension, shock, peripheral vascular disease, or hypothermia can impair peripheral perfusion, affecting the accuracy of pulse oximetry measurements. Reduced blood flow to the extremities may result in weak or absent pulse signals, leading to unreliable oxygen saturation readings despite adequate arterial oxygenation [7].

Skin Pigmentation: Skin pigmentation, particularly in individuals with darker skin tones, can affect the transmission of light through the skin and alter the accuracy of pulse oximetry readings. Increased melanin content may attenuate the light signal, leading to underestimation of oxygen saturation levels [8].

Nail Polish and Artificial Nails: Nail polish, acrylic nails, or other nail enhancements can interfere with the proper placement of pulse oximeter sensors and affect light transmission through the nail bed. This interference may lead to inaccurate oxygen saturation readings or signal loss, especially if the nail polish is dark or opaque [9].

Intravenous Dyes and Pigments: Administration of intravenous dyes or medications containing pigments (e.g., methylene blue, indocyanine green) can alter the color of blood and affect the accuracy of pulse oximetry measurements. These substances may absorb or scatter light in the vascular bed, leading to erroneous oxygen saturation readings [10].

Conclusion

Monitoring oxygen saturation in acute and critical care settings is essential for assessing patients' respiratory status and guiding appropriate interventions. Despite its importance, several challenges exist that can affect the accuracy and reliability of oxygen saturation measurements. These challenges include patient movement, poor peripheral perfusion, skin pigmentation, nail polish/artificial nails, intravenous dyes, ambient light, low perfusion states, respiratory conditions, altitude, and device-related factors. Despite these challenges, advancements in technology and ongoing research continue to improve the accuracy and reliability of oxygen saturation monitoring in acute and critical care settings. Future efforts should focus on developing innovative monitoring solutions, enhancing staff training, and integrating oxygen saturation data into comprehensive patient care protocols.
