This study tested two ways to remove a breathing tube after a C-section to see which one helps mothers breathe better right after surgery. Researchers compared a gentle airflow method to a suction method in 120 women having planned C-sections. The main goal was to see which techn…

This study tested how accurately three different brands of smartwatches measure blood oxygen levels compared to a standard medical device. Eighteen healthy volunteers wore the watches while their oxygen levels were safely lowered in a controlled setting. The goal was to see if co…

This study tested how accurately pulse oximeters measure blood oxygen levels and heart rate. Researchers compared readings from finger-clip devices to blood samples and heart monitors in 11 healthy adults. Participants breathed controlled low-oxygen air while at rest to see how w…

This study tested how accurately a new type of pulse oximeter measures blood oxygen levels and heart rate. Eleven healthy adults wore the device while breathing different levels of oxygen in a controlled setting. Researchers compared the device's readings to measurements from blo…

This study tested whether using a special monitor that tracks multiple breathing signals could help prevent low oxygen levels in patients aged 65 and older during painless colonoscopy. Researchers compared patients using this new monitor to patients using a standard oxygen monito…

This study tested whether placing children on their stomachs at specific head-up angles (10°, 30°, or 45°) helps their heart and lung recovery after congenital heart surgery. Researchers monitored 102 infants and children to see which angle best improved breathing support and all…

This study aimed to find out if the finger you choose to place a pulse oximeter sensor on affects the oxygen level reading it gives. Researchers tested 24 healthy volunteers by having them briefly breathe air with low oxygen and high carbon dioxide while wearing sensors on all th…

This research study aimed to understand how men's and women's bodies differ in controlling blood flow when oxygen levels drop. Researchers measured blood flow in the arms of 31 healthy adults aged 18-45 while they breathed air with reduced oxygen. The goal was to gather basic kno…

This study compared two ways to measure oxygen levels in ICU patients who needed extra oxygen. Researchers checked if readings from a simple finger clip monitor matched results from more invasive blood tests. The goal was to understand how well these two methods correlate in crit…

This study aimed to understand how exercising with less oxygen affects muscle growth at the cellular level. Researchers had 38 healthy young men perform specific resistance exercises under normal and low-oxygen conditions. They took muscle and blood samples at different times to …

This study aimed to check how well a new type of pulse oximeter works. Pulse oximeters are the small clip-on devices that measure blood oxygen levels without a needle. Researchers tested it on 12 healthy adults by having them breathe different oxygen mixtures while at rest, compa…

This study aimed to understand how sleep apnea and low oxygen levels affect muscle strength and lung function in people with chronic spinal cord injury. Researchers measured hand grip strength and collected blood samples from 30 participants with cervical spinal cord injuries to …

This study aimed to understand how spinal anesthesia affects a patient's oxygen levels during varicose vein surgery. Researchers monitored 56 patients using a standard oxygen sensor and a newer one that gives an early warning. The goal was to see if the level of numbness from the…

This study aimed to understand how low oxygen at high altitudes affects the brain and body. Researchers compared 20 healthy adults experiencing real mountain altitude with others in a lab that simulated the same low-oxygen conditions. They measured brain oxygen, heart rate, stres…

This study tested how accurately a new model of pulse oximeter measures blood oxygen levels and heart rate. Researchers compared the device's readings on healthy volunteers' fingers to measurements taken from blood samples and heart monitors. The goal was to gather performance da…

This study aimed to understand how the brain responds to exercise when oxygen levels are low, like at high altitudes. Researchers tested 30 healthy men using brain scans and other tools while they exercised in normal and low-oxygen air. The goal was to learn if the brain itself c…

This study aimed to understand why people with obstructive sleep apnea (OSA) have a higher risk of developing diabetes. Researchers compared 48 people with OSA, some who had low oxygen levels (hypoxia) and some who did not, to see if low oxygen caused more severe insulin resistan…

This study aimed to understand how breathing different gas mixtures—some with low oxygen or high carbon dioxide—affects basic body functions in healthy people. Fifteen volunteers breathed different gas combinations while researchers measured their heart function and blood flow. T…

This study aimed to understand sleep quality and breathing patterns in adults undergoing orthodontic treatment. Researchers enrolled 52 patients and had them wear a smart ring and use a phone app for a week to track sleep, snoring, and oxygen levels. The goal was to gather data t…

This study tested a new training system designed to help military pilots handle the effects of high G-forces, which can cause vision loss and blackouts. Researchers used a special tilting table and leg chamber to safely simulate the blood pressure drops and blood pooling that pil…

This study aimed to check how accurate a new model of pulse oximeter is when people are moving. Pulse oximeters are the small clip-on devices that measure blood oxygen and heart rate without a needle. Researchers tested the device on 5 healthy adults while they performed controll…

This study aimed to see if wearing FFP2/N95 masks affects oxygen levels and heart rate in people who wear them for work. Researchers measured these vital signs in 60 dental professionals while they wore the masks. The goal was to gather information on mask safety, not to test a t…
