[Monitoring of FiO2 mask under nebulized oxygen therapy for post-heart surgery patients].
Using Oxygen-Meter measure FiO2 directly inside the patient's mask in different oxygen flow. The purpose was to realize the actual FiO2 that patient inspirated. So oxygen therapy can be carried on correctly and scientifically and provide basis for respiratory monitoring and management post heart surgery. When patient breathe in oxygen in mask nebulize way, a porbe of oxygen meter was put in through a side hole 10 minutes later, the result was recorded. It demonstrated that when oxygen flow was 5L/min FiO2 inside mask was 56% approximately 58%. That means it's not correct to determine FiO2 according to the oxygen flow meter. The oxygen-meter should be used to monitor in order to avoid complications caused by incorrect adjustment and ensure the post heart surgery patient to recovery quickly.
