Outcome Measures

Primary Outcomes (1)

  • Evaluation of the changes in oxygen saturation, heart rate, respiratory rate, blood pressure, dyspnea score and arterial blood gases in bronchoscopy procedure

    Evaluate changes and when to reach base line in each of 1- (SPO2) by pulse oximeter in (percentage %) at base line, 15 minute before, during and immediately after bronchoscopy. 2-heart rate in (beat/minute) at base line, 15 minute before, during and immediately after bronchoscopy. 3-respiratory rate in (cycle/minute) at base line, 15 minute before, during and immediately after bronchoscopy. 4-mean arterial blood pressure in {millimeter/mercury mm/Hg)} at base line, 15 minute before, during and immediately after bronchoscopy. 5-dyspnea score in {grade 0-3 according to: (mMRC)} 15 minute before and immediately after bronchoscopy. arterial blood gases (PH, Paco2 in {millimeter/mercury (mm/Hg)}, Pao2 in {millimeter/mercury (mm/Hg)},Spo2 (percentage %) andHco3 in {millimol (mmol/l)} before and after bronchoscopy. To show effects of using NIV and conventional o2 therapy and using of conventional o2 therapy alone on these parameters in the studied patients in bronchoscopy.

Masking Details
Sample method: Method of randomization was stratified random sampling method was adopted to create matched study groups. Patients admitted for bronchoscopy were classified into two categories: 1. A) Non hypoxemic group. 2. B) Hypoxemic group. 3. From each category: 50 patients were selected and allocated randomly in the study groups (either intervention or control group) using lottery method. So, each study group with included 25 patients from each category forming a total of 50 patients in each studies categories.
