Introduction:
Oropharyngeal dysphagia is a severe swallowing disorder with consequences that can be life-threatening or impair quality of life. One of the major risks is laryngeal penetration, which can lead to the bolus being aspirated. It is best assessed and quantified using the Penetration-Aspiration Scale (PAS), which is a validated tool in English. Our aim was to translate in French and validate the French version of the Penetration-Aspiration Scale (Fr-PAS).
Methods:
Our study was 2-fold: (i) to assess the contribution of the Fr-PAS for French-speaking speech-language therapists (SLTs) in their management of dysphagic patients using a survey questionnaire and (ii) to translate the scale and to perform linguistic and psychometric validation of the Fr-PAS and its reliability by assessing 64 video sequences from patients with oropharyngeal dysphagia using fiberoptic endoscopic evaluation of swallowing. Intrarater reliability was assessed using a 15-day test-retest procedure by Kendall tau. Interrater reliability was evaluated using Cronbach's alpha.
Results:
The survey demonstrated strong interest in the use of Fr-PAS, with 96.43% of SLTs providing positive responses. The Fr-PAS reported high internal consistency (α = 0.85) and reproducibility (τ = 0.8583 and p < 0.001).
Conclusion:
The Fr-PAS is reliable and reproducible over time. The tool responds to a specific demand in assessing the severity of dysphagia and its management by SLT and the clinical team.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

01:20Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
