A

  • Diaphoresis: excessive sweating
  • Tachycardia: HR >100

Q

Q: What 2 things must we determine FIRST in order to DIAGNOSE asthma?

A

Determine an airflow obstruction is present and if it is at least partially reversible

  • What “at least partially reversible” means: the obstruction in the airways can improve significantly after administering a bronchodilator, but it might not return to completely normal function. This characteristic helps differentiate asthma from other respiratory conditions.

Q

Stages of ABG’s in Asthma:

Q: At FIRST, what do arterial blood gas (ABG) results typically show in asthma?

A

Q

ABG’s in Asthma:

What shows LATER in ABGs during an asthma attack?

Q

Q: What does a NORMAL PaCO2 level indicate during an asthma attack?

A

A: It may signal impending respiratory failure.

  • It suggests that the patient may NOT be effectively ventilating and could be losing the ability to breathe adequately.

Q

Which assessment finding would be MOST CONCERNING in a patient having an asthma attack?

a. Inspiratory wheezing
b. Productive cough
c. Tachycardia
d. Expiratory wheezing

A

a. Inspiratory wheezing
(high-pitched, musical sound that occurs during INHALATION)

  • It suggests a more severe degree of airway obstruction and may indicate impending respiratory failure or significant respiratory distress.

Q

What is the Methacholine challenge?

A
  • test is performed to evaluate how “reactive” or “responsive” your lungs are- INDUCES asthma attack
  • inhale doses of methacholine, a drug that can cause narrowing of the airways.
  • A breathing test will be repeated after each dose of methacholine to measure the degree of narrowing or constriction of the airways

78
Q

Asthma:

What does a “silent chest” indicate in a Asthma patient?

A
  • Indicates that the patient may be in status asthmaticus- a medical emergency requiring immediate intervention.
  • is dangerous and an ominous sign indicating severe airway obstruction and impending respiratory failure.
79
Q

6 steps to Manage & Teach patients with Asthma.

A
  • Managed by EARLY treatment and education
  • Written asthma action plan
  • Quick-acting beta adrenergic agonist medications (SABA)- FIRST
  • Systemic corticosteroids if do not respond to SABA medications- SECOND
  • Supplemental oxygen if hypoxic
  • Peak flow monitoring
80
Q

What is Status Asthmaticus

A
  • Now its called “Severe life-threatening asthma attack”
  • Rapid onset, severe, persistent asthma attack that does NOT respond to usual treatment
  • High risk for respiratory failure
  • Pt usually ends up on ventilator
81
Q

S/S of Status Asthmaticus

A

Same as sever Asthma with:
* PROLONGED exhalation
* Distended Neck Veins
* Wheezing -as obstruction worsens, wheezing may disappear = impending resp. Failure!!! **

82
Q

Assessments & Dx findingsfor Status Asthmaticus

A
  1. Ability to talk
  2. LOC
  3. Positioning
  4. ABGs: LOW PaCO2 in beginning due to increased breathing
83
Q

Most common diagnostic findings for Status Asthmaticus

A

ABGs: LOW PaCO2 (in beginning)
(plus increased PH= respiratory ALKALOSIS)

84
Q

As Asthma gets worse ABGs change.

A

HIGH PoCO2 (can become normal levels)
and
DECREASED PH
* increased PaCO2 bc they can’t breath it out.
* Both of these reflecting Respiratory ACIDOSIS = signals IMPENDING RESP. FAILURE.

85
Q

Medical mgmt of Status Asthmaticus:

After administering SABAs (inhaled), systemic corticosteroids, and supplemental oxygen for hypoxia in status asthmaticus, what additional medication may be given, and at what dosage if did NOT respond to the initial tx.

A
  • Magnesium sulfate: help relax bronchial smooth muscle and reduce airway resistance
  • Single dose over 20 minutes

-all of this can cause flushing, tingling, CNS depression, respiratory depression, hypotension

86
Q

Medical mgmt of Status Asthmaticus:

Adverse effect of Magnesium sulfate

A
  • flushing
  • tingling
  • CNS depression
  • respiratory depression
  • hypotension
87
Q

Complications of severe asthma can be caused by

A

the increased pressures within the pulmonary system
