"سَل عنَّا الليل والكتب ومضاجع باتت تشكينا
وجحيمُ الطبِ إذا نشبَ بليالٍ كادت تردينا"

أخر ليالي الطب ومعاها تنتهي الأيام ُالمريرة "إن شاء الله".
الليالي دي على الرغم من صعوبتها ومشاعر الخوف واليأس والجذع اللي بتصيب الإنسان ،
إلا أنها أكتر ليالي نحسُ فيها بمعية الله عز وجل ولطفه بينا وإنها مش بتعدي كل مرة غير بكرمه وعمرها ما كانت بجهودنا.
اللهم لك الحمد ربنا لا نحصي ثناءاً عليك أنت كما أثنيت علي نفسك ، نسألك بفضلك ألا تحرمنا بذنوبنا أجر هذه الليالي وأن تجعلها خالصة لوجهك الكريم، ونسألك تمام فضلك وكرمك وأن تبلغنا أخر يوم في عفو وعافية ورضا منك يا كريم.❤🥰

■ السؤال دا ليه تشخيصه PE :

♤ لأنها جايه ب acute breathless من PE بسبب hypoxia و دا بان عندي low Pao2 و حصل hyperventilation دا دليل انه low PaCo2 و بعد كدا حصل alkalosis

■ ليه مينفعش DKA ؟ لانه بيعمل acidosis

■ ليه م ينفعش severe vomting لانه بيؤدي إلى metabloic alkalosis و دا بيظهر عندي high PH & high HCO3 و Pao2 مش بيقل

■ ليه م ينفعش panic attack ؟ لأنه بيحصل acute alkalosis في عدم وجود hypoxia
