Abstract:
The presence of a palatal cleft at birth should not prevent good speech production in most children provided they have (1) appropriate surgical intervention to close the palate at or around the child's first birthday, (2) careful monitoring of speech development throughout childhood, (3) speech therapy when needed, and (4) secondary surgical or speech-prosthetic intervention when needed. When managed carefully by an experienced, well-prepared multidisciplinary team that applies the criteria listed above, ~70% of children with nonsyndromic palatal clefts will have no significant difficulties with speech intelligibility or speech quality due to velopharyngeal insufficiency by the time they enter elementary school. Speech assessment is the first step toward comprehensive team management of children with cleft palate. The purpose of this chapter is to describe the use of instrumentation in the evaluation of speech of children with palatal clefts, within the context of a multidisciplinary team. The focus of this article is on instruments that are used to supplement the perceptual assessment to document current speech status and plan management strategies.

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:

A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
