How is respiration regulated? | Inhale - exchanges of gasses across membranes. Exhale due to increased C02. Accessory muscles used. |
Normal rate of respiration - Adult | 12-20 |
Normal rate of respiration - Over 70 | 15-20 |
Normal rate of respiration - Teen | 15-20 |
Normal rate of respiration - Child | 15-25 |
Normal rate of respiration - Infant | 30-60 |
Tachypnea | greater than 20 |
Bradynea | less than 10 -meds, brain damage |
Hyperventilation | Increased rate and depth |
Hypoventilation | Decreased, can be due to narcotics/anesthesia |
Cheyne - Stokes | Rapid followed by apnea Overdose, heart failure, cranial pressure |
Biot | irregular -meningitis, brain damage |
Orthopnea | easier to breathe in an upright |
Arterial Oxygen saturation | Pulse ox normal 90-100 |
Hypoxia | inadequate cellular oxygenation |
5 interventions for client with impaired respiratory status | -monitor Spo2 sat -adjust position to maximize breathing -encourage coughing, turning -assist with spirometer -assist with walking 3-4 x daily -give meds that promote airway patency -teach breathing technique |
blood pressure | refers to force of blood against arterial walls |
systolic pressure | number on top, highest pressure formed when heart contracts (systolr) and ejects blood into the arteries |
diastolic pressure | lowest pressure, heart at rest, refills |
mean arterial pressure | MAP is average pressure within arteries |
normal BP range | 120/80 |
BP pattern | compare client's BP to his regular BP to make determination about normal/abnormal |
brachial blood pressure reading | left arm at heart level, pump to 20 mmg over, let air out slowly, document |
cuff size | must be appropriate to get accurate reading |
What neurological center controls respiration? | medulla oblongata pons |
